Mitral Transcatheter Edge-to-Edge Repair in a Pregnant Woman: Procedure and Pregnancy Outcomes

Secondary mitral regurgitation (MR) associated with left ventricular dysfunction carries a high risk of acute heart failure during pregnancy because of associated hemodynamic changes. Mitral transcatheter edge-to-edge repair (TEER) is currently recommended for symptomatic patients with secondary MR; however, no evidence exists on the use of this therapy in pregnancy. We present a case of secondary MR in a pregnant woman with dilated cardiomyopathy. She was successfully treated with TEER with minimal use of fluoroscopy (35 seconds). This is the first case to our knowledge of mitral TEER during pregnancy described in the literature, suggesting feasibility and safety of this procedure.
