# Explantation of Two Embolized Balloon-Expandable Valves in Left Atrium After Transcatheter Mitral Valve Replacement

## TL;DR

An elderly man had a complex heart valve procedure where two valves accidentally moved to the wrong place but were successfully removed.

## Contribution

This case report highlights a rare complication and successful management of embolized valves during TMVR.

## Key findings

- Two TMVR valves embolized into the left atrium during the procedure.
- The valves were successfully explanted without additional valve intervention.
- Post-procedure echocardiography showed significant improvement in mitral stenosis.

## Abstract

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.
