Urgent exploratory cardiotomy successfully explants 2 embolized valves from the left atrium following complicated TMVR.
Case Report (n=1)
No
This case demonstrates the successful surgical explantation of embolized transcatheter mitral valves and highlights the risk of valve embolization during TMVR.
Embolized TMVR valves may require urgent surgical retrieval; this case leaves open questions on incidence and prevention strategies.
An 81-year-old man with a history of transcatheter aortic valve replacement for severe aortic stenosis presented with dyspnea on exertion and moderate-severe mitral stenosis. He underwent transcatheter mitral valve replacement (TMVR) through a transseptal approach, given his age and comorbidities. The TMVR procedure was complicated by 2 embolized TMVR valves into the left atrium, requiring urgent transfer to the operating room for exploratory cardiotomy. The embolized valves were explanted from the left atrium successfully without additional mitral valve intervention. Intraoperative transesophageal echocardiography revealed improved mitral stenosis from severe to mild level after TMVR valve deployments. He was discharged home on postoperative day 10.

Marthy et al. (2024) conducted a case report in Moderate-severe mitral stenosis and embolized TMVR valves (n=1). Transcatheter mitral valve replacement (TMVR) and exploratory cardiotomy was evaluated on Successful explantation of embolized valves and improvement of mitral stenosis. Urgent exploratory cardiotomy successfully explanted two embolized balloon-expandable valves from the left atrium following a complicated transcatheter mitral valve replacement.
