Key result
Double-patch pericardial sandwich repair eliminates late ventriculo-atrial communication after mitral valve replacement through 32 months.
Why the study?
Late ventriculo-atrial communication after mitral valve replacement causing heart failure and hemolytic anemia requires effective surgical repair strategies.

A double-patch sandwich technique using autologous pericardium successfully treats late ventriculo-atrial communication following mechanical mitral valve replacement, safely avoiding a high-risk redo valve replacement.
A 62-year-old man developed progressive heart failure and hemolytic anemia 11 years after mechanical mitral valve replacement (MVR). Echocardiography showed severe paravalvular regurgitation caused by a localized ventriculo-atrial communication near the anterior commissure. Intraoperatively, the prosthesis was stable and noninfected, but the annular tissue was friable. Redo valve replacement was avoided and the defect was closed with two autologous pericardial patches placed on the ventricular and atrial sides in a sandwich fashion. At 32 months, there was preserved prosthetic function, marked reverse remodeling, and no recurrent shunt.

Tsukada et al. (2026) conducted a case report in Late ventriculo-atrial communication after mitral valve replacement (n=1). Double-patch sandwich closure with autologous pericardial patches was evaluated on Clinical and echocardiographic outcomes (prosthetic function, remodeling, shunt recurrence). Double-patch sandwich closure using autologous pericardial patches successfully treated a late ventriculo-atrial communication after mitral valve replacement, with no recurrent shunt at 32 months.
