Transcatheter Mitral Valve Implantation in Failed Transventricular Mitral Valve Repair.
JACC Case Rep
April 2024
Cardiac Surgery, Department of Surgical Sciences, University of Turin, Turin, Italy.
An 84-year-old man presented with dyspnea at rest due to severe mitral regurgitation. He first underwent transventricular mitral valve repair with the Harpoon system, which relapsed owing to rupture of neochords. He was definitively treated with transcatheter mitral valve implantation of the Tendyne system 8 months later.

Background: In conventional left ventricular assist devices (LVAD), a separate outflow graft is sutured to the ascending aorta. Novel device designs may include a transventricular outflow cannula crossing the aortic valve (AV). While transversal ventricular dimensions are well investigated in patients with severe heart failure, little is known about the longitudinal dimensions.

Article Synopsis
- A 68-year-old man had heart surgery to replace a valve but later had serious complications needing more surgery.*
- He faced another issue called a "trapped valve leaflet" that made his heart not work well.*
- Doctors used a new, less invasive method to fix the trapped leaflet, and he was able to go home 12 days later, showing hope for similar patients in the future.*
Three-Dimensional Finger Test: A New Echocardiographic Method to Locate the Best Access Site During NeoChord Procedure.

Objective: Transventricular beating-heart mitral valve repair (TBMVR) with artificial chordae implantation is a technique to treat mitral valve prolapse. Two-dimensional (2D) echocardiography completed with simultaneous biplane view during surgeon finger pushing on the left ventricular (LV) wall (finger test [FT]) is currently used to localize the desired LV access, on the inferior-lateral wall, between the papillary muscles (PMs). We aimed to compare a new three-dimensional (3D) method with conventional FT in terms of safety and better localization of LV access.

The NeoChord procedure is an echo-guided trans-ventricular beating-heart mitral valve repair technique to treat degenerative mitral regurgitation (MR) due to prolapse and/or flail. The aim of this study is to analyze echocardiographic images to find pre-operative parameters to predict procedural success (≤moderate MR) at 3-year follow-up. Seventy-two consecutive patients with severe MR underwent the NeoChord procedure between 2015 and 2021.
