Conduction delays after transcatheter aortic valve implantation with balloon-expandable prosthesis and high implantation technique

, 2022
: Performing transcatheter aortic valve implantation with high implantation technique, i.e. with an aorto-ventricular ratio > 60/40, reduces the need of permanent pacemaker implantation.

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

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

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).
