Bioinspired Passive Flow Routing to Mitigate Thrombosis in Prosthetic Heart Valves and Cardiovascular Devices

Advanced Science, EarlyView.
Bioinspired passive flow routing mitigates thrombosis in cardiovascular devices by redirecting a small fraction of forward flow into stagnation‐prone regions. Inspired by avian alula and aircraft slat mechanisms, strategically placed routing channels restore washout around mechanical heart valves, reducing low‐shear exposure by four orders of magnitude

Hyperbranched poly‐L‐lysine surface‐engineered bioprosthetic heart valves with anti‐calcification, anti‐infection, and durability

BMEMat, EarlyView.
The challenges of bioprosthetic heart valves (BHV) with respect to calcification, infection, and poor durability are tackled by surface engineering of hyperbranched poly‐L‐lysine (HBPL), providing a translational solution to improve long‐term valve performance.

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).

Same‐Day Discharge After Transcatheter Aortic Valve Implantation: Who, When, and How?

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The burden of severe aortic stenosis requiring treatment is growing due to ageing populations. This places increased demands on health resources due to the growing number of transcatheter aortic valve implantation (TAVI) procedures and hospital bed occupancy.
