Key result
Complex redo mitral valve replacement in a patient with a degenerated bioprosthesis was complicated by early dehiscence of the mechanical valve, leading to multi-organ failure and death.
Case Report (n=1)
This case highlights the severe risks, including early mechanical valve dehiscence and multi-organ failure, associated with complex redo mitral valve replacement in patients with rheumatic heart disease.
This case of complex redo MVR in degenerated bioprosthesis does not change practice; leaves open questions on optimal timing and durability.
A female patient in her early 50s with rheumatic heart disease (RHD) presented with symptoms of cardiac failure 13 years following a bioprosthetic mitral valve replacement (MVR). Echocardiography revealed degenerated MVR, resulting in severe mitral regurgitation (MR), severe tricuspid regurgitation, and pulmonary hypertension, warranting complex redo MVR with atrioventricular groove reconstruction and tricuspid valve annuloplasty. The perioperative period was complicated by multi-organ failure due to early dehisce of the mechanical MVR leading to the tragic death of this patient.

Kazi et al. (2025) conducted a case report in Rheumatic heart disease with degenerated bioprosthetic mitral valve replacement (n=1). Complex redo mitral valve replacement with atrioventricular groove reconstruction and tricuspid valve annuloplasty was evaluated. Complex redo mitral valve replacement in a patient with a degenerated bioprosthesis was complicated by early dehiscence of the mechanical valve, leading to multi-organ failure and death.
