Summary
Transcatheter mitral valve replacement in failed surgical rings is challenging. This case highlights successful valve-in-ring TMVR using leaflet and stitch laceration techniques to prevent obstruction and ensure hemodynamic stability.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Cardiac Surgery
Background:
- Transcatheter mitral valve replacement (TMVR) in patients with prior surgical mitral valve repair, particularly those with failed rings and an Alfieri stitch, presents significant therapeutic challenges.
- Severe mitral regurgitation and pulmonary hypertension in such patients can lead to acute decompensated heart failure, often precluding redo surgery.
- Dynamic left ventricular outflow tract (LVOT) obstruction is a recognized risk in TMVR, especially when specific anatomical features like a long anterior mitral leaflet are present.
