MULTICENTER EVALUATION OF PROSTHESIS OVERSIZING FOR THE SAPIEN 3 TRANSCATHETER HEART VALVE – IMPACT ON NEW PACEMAKER IMPLANTATIONS

Journal of the American College of Cardiology, 2017
Background: Prosthesis sizing in transcatheter aortic valve replacement (TAVR) uses certain prosthesis oversizing (OS) to achieve device success. However, an increase in OS may increase the need for permanent pacemaker implantations (PPI).

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

Multicenter Evaluation of Prosthesis Oversizing of the SAPIEN 3 Transcatheter Heart Valve. Impact on Device Failure and New Pacemaker Implantations

Revista Española de Cardiología (English Edition), 2019
A certain degree of prosthesis oversizing (OS) is recommended for the SAPIEN 3 to achieve device success. However, an increase in OS may increase permanent pacemaker implantation (PPI) rates. We therefore investigated the influence of OS on device failure and PPI.A total of 804 patients were treated with SAPIEN 3 at 3 centers.
