Key result
Ventricular ruptures after mitral valve replacement were classified into type 1 (atrioventricular groove) and type 2 (midventricular wall) based on the site of the tear in 7 cases.
Why the study?
Ventricular rupture after mitral valve replacement is a rare and often fatal complication.
Left ventricular rupture after mitral valve replacement is a rare, fatal complication historically classified into atrioventricular groove (type 1) and midventricular wall (type 2) tears.
Site-based classification may aid recognition of rare post-MVR rupture; leaves open validation in larger cohorts.
Ventricular rupture after mitral valve replacement (MVR) is a rare and often a fatal complication of this operation. This problem was first presented at the 39th Annual Meeting of the American College Chest Physicians in Toronto, on October 22, 1973, by Dr Robert L. Treasure and colleagues.1 Those investigators collected 7 cases from 3 hospitals and, based on the site of the ventricular tear, they classified the ventricular ruptures in type 1 (atrioventricular groove) and type 2 (midventricular wall).

Tirone E. David (2020) studied Ventricular rupture after mitral valve replacement (n=7). Mitral valve replacement was evaluated on Site of ventricular tear. Ventricular ruptures after mitral valve replacement were classified into type 1 (atrioventricular groove) and type 2 (midventricular wall) based on the site of the tear in 7 cases.
