Transcatheter mitral valve replacement in native mitral valve with severe mitral annular calcification: Skirting the Sapien 3 to reduce the risk of paravalvular leaks

Frontiers in Cardiovascular Medicine, 2022
BackgroundMitral annular calcification (MAC) may represent a significant challenge for heart surgeons with an extremely high perioperative risk during mitral valve (MV) surgery.

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).

The Heart Team during the Pandemic: A Case Report of Bio-Prosthesis Degeneration Treated with Valve in Valve Implantation

Journal of Cardiovascular Echography
The pandemic changed the type of patients. The concept of “patient at the center” became concrete. The execution of simple consultancy was overcome to create effective collaboration and fruitful exchanges between specialists. The “Heart Team” model is on increasing affirmation.

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.

Macrophage‐targeted cerium‐tannic acid metal‐polyphenol framework nanoenzyme promotes in situ heart valves regeneration through adaptive immunomodulation

BMEMat, EarlyView.
A novel nanoenzyme based on cerium ions‐tannic acid metal‐polyphenol framework (FCT) has been developed and loaded onto DHVs for targeting M1 macrophages to reduce their ROS level and reprogram macrophage phenotype, thereby eliminating inflammation, promoting endothelialization and adaptive matrix remodeling of scaffolds, offering a promising strategy ...

Single Centre Experience With the Balloon‐Expandable Myval Transcatheter Aortic Valve System in Patients With Bicuspid Anatomy: 1 Year Follow‐Up

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter aortic valve implantation (TAVI) in bicuspid aortic valve (BAV) anatomy remains challenging due to anatomical complexity and limited trial data. New‐generation balloon‐expandable valves, such as Myval, require further evaluation in this subgroup.
