Transcatheter aortic valve implantation (TAVI) is an emerging technology used to treat high-risk patients with severe aortic stenosis. During TAVI with the CoreValve ReValving System, a balloon is used for the reduction of paravalvular regurgitation. However, in this paper, we describe the "balloon withdrawal" technique through which the positioning of a second valve can be avoided in case of i...

Objectives: Continuous ambulatory peritoneal dialysis (CAPD) is an established alternative method to hemodialysis for treating endstage renal disease patients. Malfunction of the peritoneal catheter is a frequent complication in peritoneal dialysis (PD). Laparoscopy is a minimal invasive technique that allows rescue therapy of malfunctioning catheters and consecutive immediate resumption of PD....

The factors governing the characteristic laminated termination of hippocampal afferents are essentially unknown. Principally, diffusible factors of the target region, membrane-bound molecules on the ingrowing afferent fibers and on the postsynaptic target cells as well as molecules of the extracellular matrix (ECM), may play a role. Using slice cocultures as a model, we show that hyaluronic aci...

OBJECTIVE The study sought to evaluate outcomes and predictors of mortality after transcatheter aortic valve implantation (TAVI). BACKGROUND TAVI registries can reliably address outcomes and issues that adversely affect results in real-life. METHODS All endpoints and complications were analyzed according to Valve Academic Research Consortium-2 criteria. RESULTS Between January 2008 and Ja...

Alar base retraction is a common yet difficult problem faced by the rhinoplasty surgeon. It may be caused by weakened, overresected lateral crura, vestibular lining deficiencies, or congenital alar malpositioning. Methods of correction include soft tissue manipulation, auricular composite grafting, and cartilage grafting. We present the senior author's graded approach to alar retraction using a...
