Polimorfismo do gene IL6 candidato à predisposição à rotura prematura de membranas pré-termo e ao trabalho de parto pré-termo

Introduction: Preterm Labor (PTL) and Preterm Premature Rupture of Membranes (PPROM) cause severe complications for both mother and fetus. Among the risk factors associated with preterm labor and PPROM, genetic predisposition has been gaining importance. However, the association between polymorphic genes and the pathogenesis of PTL and PPROM remains elusive. A better understanding of the genetic mechanisms underlying these adverse pregnancy outcomes may enable the identification of high risk patients and allow new approaches to minimize the deleterious effects of prematurity. Aim: To determine the association between maternal IL-6 polymorphism gene and the occurrence of PTL and PPROM. Patients and Methods: The study included 109 patients with prior history of PL and/or PPROM that delivered prematurely at the Obstetrical Unit Care of Botucatu Medical School, UNESP between 2003 and 2012. The control group consisted of 68 patients that delivered at term, matched to the case group by age, ethnicity, and sex of the newborn. Oral swabs (Cath-AllTM – Epicentre Biotechnologies) were collected for analysis of genetic polymorphisms by PCR. Statistical tests were performed to compare genotype, clinical and socio-demographic data from the groups. A p-value of <0.05 was considered significant. Results: The sociodemographic characteristics in both groups were homogeneously distributed. The frequency of the polymorphic allele C, associated with less production of IL-6, and therefore thought to be protective against PTL and PPROM, was 32,5% in the study group and 30,9% in the control group, without statistically significant differences. Conclusion: Considering the sample size included in this study, the frequency of the mutated allele is similar in pregnant women who delivered at term and gestational complications as PTL and PPROM

Outpatient versus inpatient treatment for acute pulmonary embolism

Background: Pulmonary embolism (PE) is a common life-threatening cardiovascular condition, with an incidence of 23 to 69 new cases per 100,000 people per year. Outpatient treatment instead of traditional inpatient treatment in selected non-high-risk patients with acute PE might provide several advantages, such as reduction of hospitalizations, substantial cost saving and an improvement in health-related quality of life. Objectives: To compare the efficacy and safety of outpatient versus inpatient treatment for acute PE for the outcomes of all-cause and PE-related mortality; bleeding; and adverse events such as hemodynamic instability, recurrence of PE and patients'satisfaction.Search methodsThe Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator (TSC) searched the Specialised Register (last searched October 2014) and the Cochrane Central Register of Controlled Trials (CENTRAL; 2014, Issue 9). The TSC also searched clinical trials databases. The review authors searched LILACS (last searched November 2014). Selection criteria: Randomized controlled trials of outpatient versus inpatient treatment in people diagnosed with acute PE. Data collection and analysis: Two review authors selected relevant trials, assessed methodological quality, and extracted and analyzed data. Main results: We included one study, involving 339 participants. We ranked the quality of the evidence as very low due to not blinding the outcome assessors, the small number of events with imprecision in the confidential interval (CI), the small sample size and it was not possible to verify publication bias. For all outcomes, the CIs were wide and included clinically significant treatment effects in both directions: short-term mortality (30 days) (RR 0.33, 95% CI 0.01 to 7.98, P = 0.49), long-term mortality (90 days) (RR 0.98, 95% CI 0.06 to 15.58, P = 0.99), major bleeding at 14 days (RR 4.91, 95% CI 0.24 to 101.57, P = 0.30) and 90 days (RR 6.88, 95% CI 0.36 to 134.14, P = 0.20), recurrent PE within 90 days (RR 2.95, 95% CI 0.12 to 71.85, P = 0.51) and participant satisfaction (RR 0.97, 95% CI 0.92 to 1.03, P = 0.30). PE-related mortality, minor bleeding, and adverse course such as hemodynamic instability and compliance were not assessed by the single included study. Authors' conclusions: Current very low quality evidence from one published randomized controlled trial did not provide sufficient evidence to assess the efficacy and safety of outpatient versus inpatient treatment for acute PE in overall mortality, bleeding and recurrence of PE adequately. Further well-conducted research is required before informed practice decisions can be made.

Use of botulin toxin in the treatment of diffuse esophageal spasm. A case report

The diffuse esophageal spasm distinguishes from others esophageal disturbs by the symptoms severity and bad results to conservative treatment. This situation requires formal indication to surgical treatment or dilation. In high risk patients this situation becomes a big problem, due to the lack of another therapeutic option. In a patient with this problem we use an endoscopic injection of botulin toxin in cardia with good results in three months follow-up. Despite this short period of observation we believe that the infiltration with botulin toxin in cardia constitutes a valid therapeutic option in treatment of diffuse esophageal spasm.

Endovascular repair of a complex giant infrarenal abdominal aortic aneurysm

Giant aortic aneurysms (transverse diameter greater than 10.0 cm) are rare and open surgery is often the treatment of choice. We report an infrarenal saccular giant aortic aneurysm (measuring 25 cm in transverse diameter), which was treated with endovascular repair, with immediate technical success. No similar report of a giant infrarenal aortic aneurysm treated with an endovascular technique was found in the literature. High-risk patients could possibly benefit from the endovascular technique. Nevertheless, patient survival remains strongly influenced by comorbidities.

In vitro effect of sodium trimetaphosphate additives to conventional toothpastes on enamel demineralization

The aim of this study was to evaluate the ability of conventional toothpastes (1100 ppm F) supplemented with sodium trimetaphosphate (TMP) in demineralization. Blocks of enamel were selected and then divided into seven experimental groups of 12: toothpaste without F and TMP (placebo), toothpaste with 1100 ppm F (1100), and toothpaste with 1100 ppm F supplemented with TMP-1 % (1100 1 % TMP), 3 % (1100 3 % TMP), 4.5 % (1100 4.5 % TMP), 6 % (1100 6 % TMP), and 9 % (1100 9 % TMP). Blocks were subjected to five pH cycles (demineralizing/remineralizing solutions) at 37 °C and treated with toothpaste slurries twice daily, after which the blocks were maintained for 2 days in fresh remineralizing solution. Following treatments, surface hardness (SHf) and cross-sectional hardness were determined for calculating the integrated loss of subsurface hardness (ΔKHN). The fluoride present in the enamel was also measured. The SHf and ΔKHN measurements showed that supplementation with 3 % TMP was the most effective (p < 0.001) and showed greater concentration of F in the enamel (p < 0.001). Addition of 3 % TMP to a conventional toothpaste (1100 ppm F) showed greater efficacy in reducing enamel demineralization. Fluoride toothpastes containing trimetaphosphate possess good anticaries potential required to reduce the prevalence of dental caries in high-risk patients.

Expression analysis of stem cell-related genes reveal OCT4 as a predictor of poor clinical outcome in medulloblastoma

Aberrant expression of stem cell-related genes in tumors may confer more primitive and aggressive traits affecting clinical outcome. Here, we investigated expression and prognostic value of the neural stem cell marker CD133, as well as of the pluripotency genes LIN28 and OCT4 in 37 samples of pediatric medulloblastoma, the most common and challenging type of embryonal tumor. While most medulloblastoma samples expressed CD133 and LIN28, OCT4 expression was found to be more sporadic, with detectable levels occurring in 48% of tumors. Expression levels of OCT4, but not CD133 or LIN28, were significantly correlated with shorter survival (P <= 0.0001). Median survival time of patients with tumors hyperexpressing OCT4 and tumors displaying low/undetectable OCT4 expression were 6 and 153 months, respectively. More importantly, when patients were clinically stratified according to their risk of tumor recurrence, positive OCT4 expression in primary tumor specimens could discriminate patients classified as average risk but which further deceased within 5 years of diagnosis (median survival time of 28 months), a poor clinical outcome typical of high risk patients. Our findings reveal a previously unknown prognostic value for OCT4 expression status in medulloblastoma, which might be used as a further indicator of poor survival and aid postoperative treatment selection, with a particular potential benefit for clinically average risk patients.

A comparison of non-HDL and LDL cholesterol goal attainment in a large, multinational patient population: The Lipid Treatment Assessment Project 2

Objective: This study evaluated the success in attaining non-HDL-cholesterol (non-HDL-C) goals in the multinational L-TAP 2 study. Methods: 9955 patients >= 20 years of age with dyslipidemia on stable lipid-lowering therapy were enrolled from nine countries. Results: Success rates for non-HDL-C goals were 86% in low, 70% in moderate, and 52% in high-risk patients (63% overall). In patients with triglycerides of >200 mg/dL success rates for non-HDL-C goals were 35% vs. 69% in those with <= 200 mg/dL (p < 0.0001). Among patients attaining their LDL-C goal, 18% did not attain their non-HDL-C goal. In those with coronary disease and at least two risk factors, only 34% and 30% attained respectively their non-HDL-C and LDL-C goals. Rates of failure in attaining both LDL-C and non-HDL-C goals were highest in Latin America. Conclusions: Non-HDL-C goal attainment lagged behind LDL-C goal attainment; this gap was greatest in higher-risk patients. (c) 2012 Elsevier Ireland Ltd. All rights reserved.

Circoli collaterali porto-sistemici all'eco-color-Doppler addominale in pazienti con ipertensione portale cirrotica: correlazione con il gradiente porto-epatico e valore prognostico

Background. Abdominal porto-systemic collaterals (APSC) on Color-Doppler ultrasound are a frequent finding in portal hypertensive cirrhotic patients. In patients with cirrhosis, an HVPG ≥ 16mmHg has been shown to be associated with increased mortality in two studies. Non-invasive indicators of HVPG ≥ 16 mmHg might define a subgroup of high-risk patients, but data on this aspect are lacking. Aims. We aimed to investigate whether HVPG predicts mortality in patients with clinically significant portal hypertension, and if APSC may predict a severe portal hypertensive state (i.e. HVPG≥16mmHg) in patients with cirrhosis and untreated portal hypertension. Methods. We analysed paired HVPG and ultrasonographic data of 86 untreated portal hypertensive cirrhotic patients. On abdominal echo-color-Doppler data on presence, type and number of APSC were prospectively collected. HVPG was measured following published guidelines. Clinical, laboratory and endoscopic data were available in all cases. First decompensation of cirrhosis and liver-disease related mortality on follow-up (mean 28±20 months) were recorded. Results. 73% of patients had compensated cirrhosis, while 27% were decompensated. All patients had an HVPG≥10 mmHg (mean 17.8±5.1 mmHg). 58% of compensated patients and 82% of decompensated patients had an HVPG over 16 mmHg. 25% had no varices, 28% had small varices, and 47% had medium/large varices. HVPG was higher in patients with esophageal varices vs. patients without varices (19.0±4.8 vs. 14.1±4.2mmHg, p<0.0001), and correlated with Child-Pugh score (R=0.494,p=0.019). 36 (42%) patients had APSC were more frequent in decompensated patients (60% vs. 35%, p=0.03) and in patients with esophageal varices (52% vs. 9%,p=0.001). HVPG was higher in patients with APSC compared with those without PSC (19.9± 4.6 vs. 16.2± 4.9mmHg, p=0.001). The prevalence of APSC was higher in patients with HVPG≥16mmHg vs. those with HVPG<16mmHg (57% vs. 13%,p<0.0001). Decompensation was significantly more frequent in patients with HVPG≥16mmHg vs. HVPG<16mmHg (35.1% vs. 11.5%, p=0.02). On multivariate analysis only HVPG and bilirubin were independent predictors of first decompensation. 10 patients died during follow-up. All had an HVPG≥16 mmHg (26% vs. 0% in patients with HVPG <16mmHg,p=0.04). On multivariate analysis only MELD score and HVPG ≥16mmHg were independent predictors of mortality. In compensated patients the detection of APSC predicted an HVPG≥16mmHg with 92% specificity, 54% sensitivity, positive and negative likelihood ratio 7.03 and 0.50, which implies that the demonstration of APSC on ultrasound increased the probability of HVPG≥16mmHg from 58% to 91%. Conclusions. HVPG maintains an independent prognostic value in the subset of patients with cirrhosis and clinically significant portal hypertension. The presence of APSC is a specific indicator of severe portal hypertension in patients with cirrhosis. Detection of APSC on ultrasound allows the non-invasive identification of a subgroup of compensated patients with bad prognosis, avoiding the invasive measurement of HVPG.

Langzeitergebnisse nach Trabekulektomie bei Glaukompatienten

Hintergrund: Die antimetabolitgestützte Trabekulektomie stellt seit längeren denrnGoldstandard bei medikamentös nicht ausreichend therapierbaren Glaukomen dar. Kurz- und mittelfristige Erfolge wurden durch viele Studien bestätigt. Allerdings unterliegen diese sehr unterschiedlichen Erfolgsdefinitionen. Eine strikte Druckkontrolle ≤ 15 mm Hg ohne zusätzliche medikamentöse Therapie erscheint sinnvoll einen risikofreien Therapieerfolg zu bewerten. Es existieren nur wenige Langzeitstudien mit diesem Erfolgskriterium. Die durchgeführte Studie soll einen Eindruck der ophthalmologischen Versorgung trabekulektomierter Patienten an der Universitätsaugenklinik Mainz über einen bewusst langen Zeitraum bieten. Patienten und Methoden: In diese retrospektiven Studie wurden alle Patienten, die aufgrund einer fortgeschrittenen Glaukomerkrankung in den Jahren 1996, 2001 oder 2006 eine Trabekulektomie erhielten, aufgenommen. Von den 723 Augen der 664 Patienten dieser Jahrgänge konnten 447 (61,8%) nachverfolgt werden. Die Zusammensetzung der Patienten war mit anderen Studien vergleichbar. 28% konnten mindestens 7 Jahre, 10% sogar 10 Jahre nachverfolgt werden. Esrnwurde untersucht, ob ein signifikanter Zusammenhang zwischen dem ophthalomologisch-internistischem Entlassstatus (Visus, Tensio, Gesichtsfeld,rnGlaukomtyp, Voroperationen, Medikation, Vorerkrankungen, Art der Operation) undrnder erstrebten Kontrolle des Intraokulardruckes besteht. Ergebnisse: Die mittlere Nachbeobachtungszeit betrug 4,3 ± 3,4 Jahre. Nach 1, 3,rn5, 7 und 10 Jahren wiesen 217 (82,1%) (p < 0,001), 133 (67,7%) (p < 0,001), 70rn(50%) (p < 0,001), 59 (47,7%) (p = 0,056) und 16 (38,1%) (p = 0,06) Augen Intraokulardrücke ≤ 15 mm Hg ohne zusätzliche Antiglaukomatosa auf. Nichtrnstatistisch signifikant waren die 7- und 10-Jahresergebnisse. Mit Hilfe von Antiglaukomatosa waren es insgesamt, 225 (85,1%), 156 (79,7%), 87 (62,5%), 93 (75%) und 23 (54,7%) (alle p < 0,001). Die mediane Überlebenszeit für IOD ≤ 15 mm Hg ohne Medikation betrug 7,4 Jahre ± 5 Monate. Druckobergrenzen von ≤ 18 bzw. 21 mm Hg erfüllten bis zu 20% mehr Patienten. Der mittlere Visus von 0,32 ± 6 Stufen blieb nach einem mittleren postoperativen Abfall auf 0,25 ± 5 Stufen in den Folgeuntersuchungen stabil. Er zeigte ab dem 3-Jahresintervall keine statistisch signifikante Verschlechterung zum präoperativen Visus. 5,8 Jahre ± 80 Tage betrug die mediane Überlebenszeit für ein stabiles Gesichtsfeld. Gesichtsfelddaten, MD und PSD zeigten keine statistisch signifikante Verschlechterung (p > 0,05). Risikofaktoren für ein Scheitern der Operation waren Patientenalter (RR = 1,01, KI: 0,95 - 1,34, p = 0,043), arterielle Hypertonie (RR = 1,87, KI: 1,21-2,9, p = 0,005) und männliches Geschlecht (RR = 1,24; KI: 1,07 – 1,43; p = 0,004). Komplikationen waren passagere okuläre Hypotonien an 85 (19%), Fistulation an 46(10,2%), Aderhautschwellung an 29 (6,4%) –abhebung an 14 (3,1%), retinale Amotio an 9 (2%), hypotone Makulopathie an 5 (1,1%) und Hypertonien an 70 (15,6%) Augen. 150 (33,5%) Augen erhielten einen Folgeeingriff, 117 (26%) eine Phakoemulsifikation, 149 (33%) eine Fadenlockerung, 122 (27%) 5-FU-Injektionen, 42 (9,4%) eine Fadennachlegung, 33 (7,4%) ein Needling, 26 (5,8%) eine Zyklophotokoagulation, 19 (4,3%) eine Re-TE und 9 (2%) sonstige chirurgische Revisionen. Schlussfolgerung: Die Kontrolle des Augeninnendruckes ≤ 15 mm Hg ohne zusätzliche Medikation erreichten viele Patienten über einen langen Nachbeobachtungszeitraum. Die Häufigkeit der Komplikationen oder nötiger Folgeeingriffe war meist niedriger als in vergleichbaren Studien. Selbst Patienten mit hohem Risikoprofil hatten gute Ergebnisse. Aufgrund mangelnder Gesichtsfelddaten fanden sich keine Hinweise auf statistisch relevantes Fortschreiten des Glaukoms zur angestrebten medikationsfreien Druckkontrolle. Weitere Studien für einen Untersuchungszeitraum von 10 Jahren mit gleichen Erfolgskriterien wie in der vorliegenden Arbeit mit genauer Analyse der Gesichtsfelddaten wären wünschenswert, um zu belegen, dass die guten Langzeitergebnisse nach Trabekulektomie an der Universitätsaugenklinik Mainz auch eine Glaukomprogredienz dauerhaft verhindern. Damit stellt die an der Universitätsaugenklinik Mainz durchgeführte antimetabolitgestützte Trabekulektomie und deren postoperative Nachbetreuung an einer repräsentativen Population eine sichere und komplikationsarme Methode dar.

One hundred fascia-sparing myocutaneous rectus abdominis flaps: An update

Major efforts have been undertaken to reduce donor-site morbidity after abdominal flaps, which eventually culminated in the introduction of the deep inferior epigastric perforator (DIEP) flap. However, due to anatomical variations (absence of dominant perforators) and the risk of ischaemic complications, the selection of patients qualifying for a DIEP flap is limited. Furthermore, DIEP flaps can only be used as free flaps. We present our long-term experience with a dissection technique of rectus abdominis myocutaneous (RAM) flaps that was developed to circumvent these drawbacks. The dissection is characterised by preventing to sacrifice any perforators nourishing the flap and by fully preserving the anterior rectus sheath, but not the muscle. The study comprises a consecutive series of prospectively assessed patients, treated between February 2000 and April 2008. A total of 100 fascia-sparing RAM flaps were operated on 97 patients (age 22-84 years, median 64 years). Free flaps were mainly used for breast reconstruction (47 flaps/24 patients), and cranially (34) or caudally (19) pedicled flaps for soft-tissue coverage after sternectomy, urogenital tumour resection or rectum amputation. Eighty patients had a total of 213 risk factors, such as cardiovascular diseases, obesity, hyperlipidaemia, diabetes mellitus, smoking or steroid medication. Partial tissue loss (skin or fat necrosis) occurred in 13 flaps, out of which seven required surgical revision. The ischaemic complications were evenly distributed between the patient subsets. At a follow-up of 2-89 months (median 20 months), one patient showed a flap harvest-related abdominal bulge after bilateral-free transverse rectus abdominis myocutaneous (TRAM) flap. We conclude that the present dissection technique provides maximal perforator-related perfusion and minimal donor-site morbidity even in pedicled flaps and high-risk patients. In free flaps, it may, therefore, be recommended as an alternative to the DIEP flap.

Controversies in cardiovascular medicine: Chronic stable coronary artery disease: drugs vs. revascularization

Coronary artery disease remains the leading cause of mortality in most industrialized countries, although age-standardized mortality related to coronary artery disease (CAD) has decreased by more than 40% during the last two decades. Coronary atherosclerosis may cause angina pectoris, myocardial infarction, heart failure, arrhythmia, and sudden death. Medical management of atherosclerosis and its manifestation aims at retardation of progression of plaque formation, prevention of plaque rupture, and subsequent events and treatment of symptoms, when these occur as well as treatment of the sequelae of the disease. Revascularization by either percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG) is performed as treatment of flow-limiting coronary stenosis to reduce myocardial ischaemia. In high-risk patients with acute coronary syndromes (ACS), a routine invasive strategy with revascularization in most patients provides the best outcome with a significant reduction in death and myocardial infarction compared with an initial conservative strategy. Conversely, the benefit of revascularization among patients with chronic stable CAD has been called into question. This review will provide information that revascularization exerts favourable effects on symptoms, quality of life, exercise capacity, and survival, particularly in those with extensive CAD and documented moderate-to-severe ischaemia. Accordingly, CABG and PCI should be considered a valuable adjunct rather than an alternative to medical therapy.

Clinical outcome and predictors for adverse events after transcatheter aortic valve implantation with the use of different devices and access routes

Background Transcatheter aortic valve implantation (TAVI) is a treatment option for high-risk patients with severe aortic stenosis. Previous reports focused on a single device or access site, whereas little is known of the combined use of different devices and access sites as selected by the heart team. The purpose of this study is to investigate clinical outcomes of TAVI using different devices and access sites. Methods A consecutive cohort of 200 patients underwent TAVI with the Medtronic CoreValve Revalving system (Medtronic Core Valve LLC, Irvine, CA; n = 130) or the Edwards SAPIEN valve (Edwards Lifesciences LLC, Irvine, CA; n = 70) implanted by either the transfemoral or transapical access route. Results Device success and procedure success were 99% and 95%, respectively, without differences between devices and access site. All-cause mortality was 7.5% at 30 days, with no differences between valve types or access sites. Using multivariable analysis, low body mass index (<20 kg/m2) (odds ratio [OR] 6.6, 95% CI 1.5-29.5) and previous stroke (OR 4.4, 95% CI 1.2-16.8) were independent risk factors for short-term mortality. The VARC-defined combined safety end point occurred in 18% of patients and was driven by major access site complications (8.0%), life-threatening bleeding (8.5%) or severe renal failure (4.5%). Transapical access emerged as independent predictor of adverse outcome for the Valve Academic Research Consortium–combined safety end point (OR 3.3, 95% CI 1.5-7.1). Conclusion A heart team–based selection of devices and access site among patients undergoing TAVI resulted in high device and procedural success. Low body mass index and history of previous stroke were independent predictors of mortality. Transapical access emerged as a risk factor for the Valve Academic Research Consortium–combined safety end point.

Transcranial Doppler-detected cerebral embolic load during transcatheter aortic valve implantation

Transcatheter aortic valve implantation (TAVI) is an alternative to surgery for high-risk patients with severe aortic valve stenosis. Periprocedural stroke is reported at an incidence up to 10%. Magnetic resonance imaging studies have identified new onset of clinically silent ischaemic cerebral lesions more frequently (68-84%). So far, few data are available about cerebral embolism during TAVI. The aim of this study was to determine the frequency of high-intensity transient signals (HITS) and to explore differences in the HITS pattern between transfemoral and transapical access and between self-expanding (SE) and balloon-expandable (BE) deployment technique.

Physical performance limitations in adolescent and adult survivors of childhood cancer and their siblings

Purpose This study investigates physical performance limitations for sports and daily activities in recently diagnosed childhood cancer survivors and siblings. Methods The Swiss Childhood Cancer Survivor Study sent a questionnaire to all survivors (≥16 years) registered in the Swiss Childhood Cancer Registry, who survived >5 years and were diagnosed 1976–2003 aged <16 years. Siblings received similar questionnaires. We assessed two types of physical performance limitations: 1) limitations in sports; 2) limitations in daily activities (using SF-36 physical function score). We compared results between survivors diagnosed before and after 1990 and determined predictors for both types of limitations by multivariable logistic regression. Results The sample included 1038 survivors and 534 siblings. Overall, 96 survivors (9.5%) and 7 siblings (1.1%) reported a limitation in sports (Odds ratio 5.5, 95%CI 2.9-10.4, p<0.001), mainly caused by musculoskeletal and neurological problems. Findings were even more pronounced for children diagnosed more recently (OR 4.8, CI 2.4–9.6 and 8.3, CI 3.7–18.8 for those diagnosed <1990 and ≥1990, respectively; p = 0.025). Mean physical function score for limitations in daily activities was 49.6 (CI 48.9–50.4) in survivors and 53.1 (CI 52.5–53.7) in siblings (p<0.001). Again, differences tended to be larger in children diagnosed more recently. Survivors of bone tumors, CNS tumors and retinoblastoma and children treated with radiotherapy were most strongly affected. Conclusion Survivors of childhood cancer, even those diagnosed recently and treated with modern protocols, remain at high risk for physical performance limitations. Treatment and follow-up care should include tailored interventions to mitigate these late effects in high-risk patients.

Improvement of physical and mental health after transfemoral transcatheter aortic valve implantation

Transcatheter aortic valve implantation (TAVI) has emerged as a treatment alternative to surgical aortic valve replacement in elderly high-risk patients with symptomatic severe aortic stenosis. In this patient population, rapid improvement or restoration of quality of life (QoL) is at least as important as improved clinical outcomes. The purpose of the present study was to assess changes in QoL in response to TAVI.
