Immunoglobulin G4 (IgG4)-related fibroinflammatory systemic disease accounts for 7% of all noninfectious aneurysms of the thoracic aorta. A patient was admitted with a symptomatic ascending aortic aneurysm and thickened aortic wall (outer/inner diameter 55/45 mm), which was replaced. Probes revealed IgG4-related aortitis associated with a primary tuberculosis infection. Corticosteroid and antituberculosis therapies were used, and the patient's clinical evolution was favorable. The optimal treatment strategy of IgG4-related aortitis, a new entity, remains vague. Inner aortic diameter alone does not justify aortic replacement, but wall thickening may mimic intramural hematoma. In this particular case of IgG4-related aortitis, immunosuppressive treatment alone, as an alternative to a surgical procedure, may be debatable.

The observation concerns a patient who was professionally exposed to silica dust. Radiologically he presented a diffuse interstitial infiltrate and clinically an obstructive syndrome with emphysem. The diagnosis of silicosis was made. The development was followed during 12 years without important modification of the X-ray or the respiratory functions. The patient died of a ruptured aortic aneurysm. At the autopsy the examination of the lungs permitted to exclude the initial diagnosis of silicosis and to conclude to an histiocytosis X. This diagnostic mistake allows to get on some radiological, clinical and epidemiological aspects, characteristic or these both pathologies.

Dilatation of the ascending aorta (AAD) is a prevalent aortopathy that occurs frequently associated with bicuspid aortic valve (BAV), the most common human congenital cardiac malformation. The molecular mechanisms leading to AAD associated with BAV are still poorly understood. The search for differentially expressed genes in diseased tissue by quantitative real-time PCR (qPCR) is an invaluable tool to fill this gap. However, studies dedicated to identify reference genes necessary for normalization of mRNA expression in aortic tissue are scarce. In this report, we evaluate the qPCR expression of six candidate reference genes in tissue from the ascending aorta of 52 patients with a variety of clinical and demographic characteristics, normal and dilated aortas, and different morphologies of the aortic valve (normal aorta and normal valve n = 30; dilated aorta and normal valve n = 10; normal aorta and BAV n = 4; dilated aorta and BAV n = 8). The expression stability of the candidate reference genes was determined with three statistical algorithms, GeNorm, NormFinder and Bestkeeper. The expression analyses showed that the most stable genes for the three algorithms employed were CDKN1β, POLR2A and CASC3, independently of the structure of the aorta and the valve morphology. In conclusion, we propose the use of these three genes as reference genes for mRNA expression analysis in human ascending aorta. However, we suggest searching for specific reference genes when conducting qPCR experiments with new cohort of samples.
Correction of pectus excavatum combined with open heart surgery in a patient with Marfan's syndrome.
Resumo:
We report a patient with Marfan's syndrome and pectus excavatum who underwent open heart surgery with simultaneous correction of the sternal malformation. Permanent internal stabilization, achieved by bilateral overlapping of the bevelled ends of the lowest ribs and reinforced with sternal closure wires offered a maintained postoperative chest wall stability, avoided the potential postoperative complications of cardiac compression, and improved the aesthetic appearance of the anterior chest wall. The increased risk of bleeding due to extensive dissection was minimized by postponing the repair of pectus excavatum to when protamin is administered after termination of cardiopulmonary bypass.

Medicare will cover a one-time preventive physical exam within the first six months that you have Part B. This benefit is for all Medicare beneficiaries including those under age 65. How much does the exam cost? You pay 20% of the Medicare approved amount after you meet the yearly Part B deductible ($131 for 2007). Since this exam may be your first Medicare-covered service, you could meet your entire Part B deductible for the year. Medicare will cover the exam if performed by a physician, physician assistant, nurse practitioner, or clinical nurse specialist. What should I expect during the exam? The “Welcome to Medicare Physical” will include the following: 1. A review of your medical and social history. 2. A review of your potential risk factors for depression. 3. A review of your functional ability and level of safety. 4. Blood pressure, height, weight and vision test 5. An electrocardiogram (EKG) 6. Education and counseling on the above five items. 7. A written plan explaining screenings and other recommended preventive services. All seven elements must be documented in order for the physical to be covered by Medicare. The exam does not include clinical laboratory tests. Medicare will pay for a one-time ultrasound screening for abdominal aortic aneurysms for beneficiaries who are at risk (has a family history or a man age 65 to 75 who has smoked at least 100 cigarettes in his lifetime.) Only Medicare beneficiaries who receive a referral from the Welcome to Medicare physical exam will be covered for this benefit. There is no Part B deductible, but you or your supplemental insurance will be responsible for the coinsurance. What should I take to the exam? You should bring the following when you go to your “Welcome to Medicare” physical exam: • Medical records, including immunization records (if you are seeing a doctor for the first time) • Family health history • A list of current prescription drugs, how often you take them, and why.

BACKGROUND AND PURPOSE: There is no strong evidence that all ischaemic stroke types are associated with high cardiovascular risk. Our aim was to investigate whether all ischaemic stroke types are associated with high cardiovascular risk. METHODS: All consecutive patients with ischaemic stroke registered in the Athens Stroke Registry between 1 January 1993 and 31 December 2010 were categorized according to the TOAST classification and were followed up for up to 10 years. Outcomes assessed were cardiovascular and all-cause mortality, myocardial infarction, stroke recurrence, and a composite cardiovascular outcome consisting of myocardial infarction, angina pectoris, acute heart failure, sudden cardiac death, stroke recurrence and aortic aneurysm rupture. The Kaplan-Meier product limit method was used to estimate the probability of each end-point in each patient group. Cox proportional hazards models were used to determine the independent covariates of each end-point. RESULTS: Two thousand seven hundred and thirty patients were followed up for 48.1 ± 41.9 months. The cumulative probabilities of 10-year cardiovascular mortality in patients with cardioembolic stroke [46.6%, 95% confidence interval (CI) 40.6-52.8], lacunar stroke (22.1%, 95% CI 16.2-28.0) or undetermined stroke (35.2%, 95% CI 27.8-42.6) were either similar to or higher than those of patients with large-artery atherosclerotic stroke (LAA) (28.7%, 95% CI 22.4-35.0). Compared with LAA, all other TOAST types had a higher probability of 10-year stroke recurrence. In Cox proportional hazards analysis, compared with patients with LAA, patients with any other stroke type were associated with similar or higher risk for the outcomes of overall mortality, cardiovascular mortality, stroke recurrence and composite cardiovascular outcome. CONCLUSIONS: Large-artery atherosclerotic stroke and cardioembolic stroke are associated with the highest risk for future cardiovascular events, with the latter carrying at least as high a risk as LAA stroke.

In the case of atherosclerotic renal artery disease, the best conclusive results lie principally not in the degree of the stenosis but rather in the degree the renal parenchymal disease beyond the stenosis itself. These determining factors involve the controlling of the patients blood pressure, the improvement in the renal function and the beneficial results to the cardiovascular system. Besides the indispensable medical treatment, a revascularisation by angioplasty may be indicated. This procedure with or without vascular stent often allows satisfactory angiographic results. A treatment by surgical revascularisation is only recommended in the case of extensive atherosclerotic lesions of the aorta, complex lesions of the latter or an abdominal aortic aneurism. Although the frequency of restenosis of angioplasty with stent remains extremely low, the risk of cholesterol emboli due to the diffuse atherosclerotic lesions of the abdominal aorta, must be considered at the time of each aortic catheterization. The therapeutic approach of atherosclerotic renal artery disease must be dictated by the whole cardiovascular risk factors and by the threat of target organs. The control of the blood pressure and the maintenance of the renal function must be integrated in the decisional algorithm as well as the possible risks in carrying out an eventual revascularisation procedure. Finally, the renal angioplasty should in numerous situations be integrated in the overall assumption of responsibility of the atherosclerotic vascular diseases, and should be part of the medical treatment. Several questions still do exist; at what moment an atherosclerotic renal artery stenosis should and e considered critical, and which procedure should be considered for which patient? The purpose of this review is to propose a decisional tool for individualized treatments in the light of results from randomized and controlled studies.

BACKGROUND/OBJECTIVES: The most recent ACC/AHA guidelines recommend high-intensity statin therapy in ischemic stroke patients of presumably atherosclerotic origin. On the contrary, there is no specific recommendation for the use of statin in patients with non-atherosclerotic stroke, e.g. strokes related to atrial fibrillation (AF). We investigated whether statin treatment in patients with AF-related stroke is associated with improved survival and reduced risk for stroke recurrence and future cardiovascular events. METHODS: All consecutive patients registered in the Athens Stroke Registry with AF-related stroke and no history of coronary artery disease nor clinically manifest peripheral artery disease were included in the analysis and categorized in two groups depending on whether statin was prescribed at discharge. The primary outcome was overall mortality; the secondary outcomes were stroke recurrence and a composite cardiovascular endpoint comprising of recurrent stroke, myocardial infarction, aortic aneurysm rupture or sudden cardiac death during the 5-year follow-up. RESULTS: Among 1602 stroke patients, 404 (25.2%) with AF-related stroke were included in the analysis, of whom 102 (25.2%) were discharged on statin. On multivariate Cox-proportional-hazards model, statin treatment was independently associated with a lower mortality (hazard-ratio (HR): 0.49, 95%CI:0.26-0.92) and lower risk for the composite cardiovascular endpoint during the median 22months follow-up (HR: 0.44, 95%CI:0.22-0.88), but not with stroke recurrence (HR: 0.47, 95%CI:0.22-1.01, p: 0.053). CONCLUSIONS: In this long-term registry of patients with AF-related stroke, statin treatment was associated with improved survival and reduced risk for future cardiovascular events.

In 2014, the debate on the indication of revascularization in case of asymptomatic carotid disease continued, while another one regarding the use of surgery vs. stenting addressed some new issues regarding the long-term cardiac risk of these patients. Renal arteries interventions trials were disappointing, as neither renal denervation nor renal artery stenting was found associated with better blood pressure management or outcome. In contrast, in lower-extremities artery disease, the endovascular techniques represent in 2014 major alternatives to surgery, even in distal arteries, with new insights regarding the interest of drug-eluting balloons. Regarding the aorta, the ESC published its first guidelines document on the entire vessel, emphasizing on the role of every cardiologist for screening abdominal aorta aneurysm during echocardiography. Among vascular wall biomarkers, the aorta stiffness is of increasing interest with new data and meta-analysis confirming its ability to stratify risk, whereas carotid intima-media thickness showed poor performances in terms of reclassifying patients into risk categories beyond risk scores. Regarding the veins, new data suggest the interest of D-dimers and residual venous thrombosis to help the decision of anti-coagulation prolongation or discontinuation after the initial period of treatment for deep vein thrombosis.

BACKGROUND AND PURPOSE: Information about outcomes in Embolic Stroke of Undetermined Source (ESUS) patients is unavailable. This study provides a detailed analysis of outcomes of a large ESUS population. METHODS: Data set was derived from the Athens Stroke Registry. ESUS was defined according to the Cryptogenic Stroke/ESUS International Working Group criteria. End points were mortality, stroke recurrence, functional outcome, and a composite cardiovascular end point comprising recurrent stroke, myocardial infarction, aortic aneurysm rupture, systemic embolism, or sudden cardiac death. We performed Kaplan-Meier analyses to estimate cumulative probabilities of outcomes by stroke type and Cox-regression to investigate whether stroke type was outcome predictor. RESULTS: 2731 patients were followed-up for a mean of 30.5±24.1months. There were 73 (26.5%) deaths, 60 (21.8%) recurrences, and 78 (28.4%) composite cardiovascular end points in the 275 ESUS patients. The cumulative probability of survival in ESUS was 65.6% (95% confidence intervals [CI], 58.9%-72.2%), significantly higher compared with cardioembolic stroke (38.8%, 95% CI, 34.9%-42.7%). The cumulative probability of stroke recurrence in ESUS was 29.0% (95% CI, 22.3%-35.7%), similar to cardioembolic strokes (26.8%, 95% CI, 22.1%-31.5%), but significantly higher compared with all types of noncardioembolic stroke. One hundred seventy-two (62.5%) ESUS patients had favorable functional outcome compared with 280 (32.2%) in cardioembolic and 303 (60.9%) in large-artery atherosclerotic. ESUS patients had similar risk of composite cardiovascular end point as all other stroke types, with the exception of lacunar strokes, which had significantly lower risk (adjusted hazard ratio, 0.70 [95% CI, 0.52-0.94]). CONCLUSIONS: Long-term mortality risk in ESUS is lower compared with cardioembolic strokes, despite similar rates of recurrence and composite cardiovascular end point. Recurrent stroke risk is higher in ESUS than in noncardioembolic strokes.

Our objective is to report a case of a patient with a descending thoracic aortic aneurysm and chronic aortic dissection, who was submitted to an endovascular treatment. A 68-year-old male with coronary artery disease and hypertension, with no history of trauma, diabetes or smoking. He had myocardial infarction ten years ago. Under general anesthesia, the left femoral artery was surgically exposed and the left braquial artery was catheterized with a "pigtail" catheter, under Seldinger technique. The proximal 46mm/Æ and distal 34mm/Æ stent-graft was placed just distal to the origen of the left subclavian artery. Control arteriography showed that the lesion was completely excluded. The patient was discharged seven days after the surgery, when a computed tomographic control, was performed showing a sustained aneurysm exclusion and a satisfactory endovascular position.

Aortotracheal fistula is a rare condition that is invariably fatal if not diagnosed and surgically treated. Patients usually present with small intermittent hemoptysis. The findings using computerized tomography (CT) are usually diagnostic. CT should be considered in the initial investigation of patients suspected to have such a disease. A 62-year-old woman with a aneurysm of the descending thoracic aorta presented with new-onset back pain and hemoptysis. The hemoptysis was thought to be the result of invasion of the bronchial tree by the aneurysm.
