Updated standardized endpoint definitions for transcatheter aortic valve implantation: the Valve Academic Research Consortium-2 consensus document

The aim of the current Valvular Academic Research Consortium (VARC)-2 initiative was to revisit the selection and definitions of transcatheter aortic valve implantation (TAVI)- clinical endpoints to make them more suitable to the present and future needs of clinical trials. In addition, this document is intended to expand understanding of patient risk stratification and case selection.

Circumferential evaluation of the neointima by optical coherence tomography after ABSORB bioresorbable vascular scaffold implantation: can the scaffold cap the plaque?

To quantify the circumferential healing process at 6 and 12 months following scaffold implantation.

The management of patients on oral anticoagulation undergoing coronary stent implantation: a survey among interventional cardiologists from eight European countries

To evaluate the current management, and adherence to recommendations, of patients on oral anticoagulation (OAC) undergoing coronary stent implantation (PCI-S).

A 3-center comparison of 1-year mortality outcomes between transcatheter aortic valve implantation and surgical aortic valve replacement on the basis of propensity score matching among intermediate-risk surgical patients

This study sought to compare all-cause mortality in patients at intermediate surgical risk undergoing transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR).

Surgical planning tool for robotically assisted hearing aid implantation

PURPOSE : For the facilitation of minimally invasive robotically performed direct cochlea access (DCA) procedure, a surgical planning tool which enables the surgeon to define landmarks for patient-to-image registration, identify the necessary anatomical structures and define a safe DCA trajectory using patient image data (typically computed tomography (CT) or cone beam CT) is required. To this end, a dedicated end-to-end software planning system for the planning of DCA procedures that addresses current deficiencies has been developed. METHODS :    Efficient and robust anatomical segmentation is achieved through the implementation of semiautomatic algorithms; high-accuracy patient-to-image registration is achieved via an automated model-based fiducial detection algorithm and functionality for the interactive definition of a safe drilling trajectory based on case-specific drill positioning uncertainty calculations was developed. RESULTS :    The accuracy and safety of the presented software tool were validated during the conduction of eight DCA procedures performed on cadaver heads. The plan for each ear was completed in less than 20 min, and no damage to vital structures occurred during the procedures. The integrated fiducial detection functionality enabled final positioning accuracies of [Formula: see text] mm. CONCLUSIONS :    Results of this study demonstrated that the proposed software system could aid in the safe planning of a DCA tunnel within an acceptable time.

Intraperitoneal mesh implantation for fascial dehiscence and open abdomen

Postoperative fascial dehiscence and open abdomen are severe postoperative complications and are associated with surgical site infections, fistula, and hernia formation at long-term follow-up. This study was designed to investigate whether intraperitoneal implantation of a composite prosthetic mesh is feasible and safe.

Combined pars plana phacofragmentation, vitrectomy, and Artisan lens implantation for traumatic subluxated cataracts

PURPOSE: To report on the outcome of combined pars plana phacofragmentation, vitrectomy, and Artisan lens implantation in the management of subluxated cataracts. METHODS: This prospective, interventional, nonrandomized case series included nine eyes of seven consecutive adult patients with traumatic lens subluxation. Pre- and postoperative data (complete manifest refraction, best spectacle-corrected visual acuity, slit-lamp examination findings, intraocular pressure, fundus status, numerical density of endothelial cells, corneal thickness, and complications) were collected prospectively for all patients. RESULTS: After a median postoperative follow-up of 12 months (range, 8-18 months), a mean spherical equivalent of -0.50 +/- 0.87 diopter (range, +1 to -1.50 diopter) was achieved. The mean logarithm of the minimum angle of resolution visual acuity improved from 1 (preoperatively) to 0.1 (postoperatively) (P = 0.007, Wilcoxon test). Median endothelial cell losses of 15 +/- 8% (P = 0.008) and 14 +/- 16% (P = 0.011) were registered at follow-ups of 1 month and 12 months, respectively. Postoperative complications included chronic intraocular inflammation and superior corectopia. CONCLUSIONS: Our procedure appears to be a safe, accurate, stable, and efficacious option for the management of traumatic subluxated cataracts in adults. However, longer-term data are needed to evaluate the corneal endothelium.
