Temporary mechanical circulatory support in cardiogenic shock.

Treatment selection and long-term survival in patients aged 50 to < 75 years undergoing valve reintervention for failed surgical aortic bioprostheses: insights from the Netherlands Heart Registration.

OBJECTIVES To describe real-world treatment allocation and observed long-term survival in patients aged 50 to < 75 years with failed surgical aortic bioprostheses who underwent reintervention through valve-in-valve transcatheter aortic valve implantation (ViV-TAVI) or redo surgical aortic valve replacement (redo-SAVR)...

Reversing Regurgitant Physiology: Pressure-Volume Insights After Dedicated TAVR for Pure Aortic Regurgitation.

BACKGROUND Dedicated transcatheter aortic valve replacement (TAVR) devices for the treatment of pure aortic regurgitation (AR) have emerged as an alternative to surgery for patients at high or prohibitive operative risk. However, the immediate hemodynamic effects of TAVR in this setting remain poorly characterized. C...

Impact of residual tricuspid regurgitation after transcatheter tricuspid therapies on right and left ventricular mechanics: insights from a case series

Abstract Background Severe tricuspid regurgitation (TR) induces right ventricular (RV) volume overload and disrupts biventricular mechanics. Tricuspid transcatheter edge-to-edge repair (T-TEER) and transcatheter tricuspid valve replacement (TTVR) are effective strategies to reduce or eliminate TR, yet their immediate p...

One-Year Outcomes of M-TEER With the PASCAL System in Atrial and Ventricular FMR: Insights From the MiCLASP Postmarket Clinical Follow-Up Study.

One-year MiCLASP results support the safety of mitral transcatheter edge-to-edge repair with the PASCAL system in both AFMR and VFMR, with comparable echocardiographic, functional, and quality-of-life changes, despite baseline differences in clinical presentation.
