Acute Mitral Regurgitation with Unilateral Left-Sided Pulmonary Edema: A Complication of STEMI Treated Successfully with a MitraClip Procedure

摘要

A 67-year-old man with inferior wall ST-segment elevation myocardial infarction underwent Impella-assisted percutaneous coronary intervention complicated by unilateral left-sided pulmonary edema and cardiogenic shock due to severe mitral valve regurgitation. Surgery was deferred due to hemodynamic instability and a high risk of mortality, so he underwent a MitraClip procedure. Mitral regurgitation (MR) is a catastrophic mechanical complication of myocardial infarction that leads to the development of pulmonary edema, cardiogenic shock, and death. After the procedure, the patient significantly reduces MR with a resolution of pulmonary edema. Acute MR can rarely present as a unilateral left-sided pulmonary edema delaying diagnosis and treatment. Transcatheter edge-to-edge repair can be a safe alternative for patients who are at high risk for surgery.
