Influence of Device Generation on Alterations of Mitral Annulus after Transcatheter Edge-to-Edge Repair: A Real-Time Three-Dimensional Transesophageal Echocardiography Study

Mari Ohmori, et al.

Objective: Alteration of the mitral annulus (MA) following transcatheter edge-to-edge mitral valve repair (TEER) is associated with a reduction in mitral regurgitation (MR). However, the influence of the new device system (MitraClip G4; Abbott Vascular, Santa Clara, CA, USA), which has 4 device size options, on the MA geometry as compared to the conventional device (G2; Abbott Vascular) remains unknown. This study aimed to investigate the influence of different device generations on the MA geometry after TEER and their association with procedural success.

Intracardiac Echocardiography via Trans-Jugular Approach for Transcatheter Tricuspid Valve Repair: In Vitro Study of Device Movement for Leaflet Detection

Shingo Kuwata, et al.

Objective: Severe tricuspid regurgitation (TR) is linked to poor prognosis, and transcatheter edge-to-edge repair (Tricuspid-TEER) has become a promising therapeutic option. However, intraprocedural imaging remains challenging. While transesophageal echocardiography (TEE) is the standard, it may not always provide optimal visualization and can cause esophageal injury.

Hemolytic Anemia Caused by Paravalvular Regurgitation after Transcatheter Aortic Valve Implantation That Required Aortic Valve Replacement: A Case Report

Hidetaka Kariya, et al.

Objective: We report a rare case of severe hemolytic anemia caused by residual paravalvular leak (PVL) following transcatheter aortic valve implantation (TAVI), which ultimately required surgical aortic valve replacement (AVR).
