Real-Time Hemodynamic Guidance During Valve-in-Valve TAVI.

OBJECTIVES To describe hemodynamic guidance during valve-in-valve transcatheter aortic valve implantation using simultaneous aortic and left ventricular pressure monitoring. KEY STEPS A 90-year-old woman with a failed 19-mm surgical bioprosthesis and severe transvalvular regurgitation underwent valve-in-valve implant...

Right internal jugular approach for transcatheter edge-to-edge mitral valve repair using the MitraClip G4 system after failed transfemoral access: a case report

Transcatheter edge-to-edge repair of the mitral valve is conventionally performed via transfemoral venous access. When this route is not feasible, the right internal jugular vein may provide an alternative, but procedural experience remains limited. A 93-year-old woman with refractory heart failure had atr...

Early-Phase Trajectory of Right Ventricular Hemodynamics during Microaxial Flow Pump Support for Cardiogenic Shock

Background Right ventricular dysfunction (RVD) is common in cardiogenic shock and associated with poor outcomes. However, early RVD trajectories after initiation of percutaneous ventricular assist device (PVAD) support and their prognostic implications remain unclear. Objectives The objectives of the study was to chara...
