Background: Cardiogenic shock (CS) associated with severe mitral regurgitation (MR) forebodes a high risk of morbidity and mortality. Transcatheter edge-to-edge repair (TEER) is a rapidly evolving technique for severe MR in haemodynamically stable patients. However, the safety and efficacy of TEER for severe MR in CS are not well established. Case summary: An 83-year-old male presented with dyspnoea and was hospitalized for heart failure. Chest X-ray revealed pulmonary oedema. Transthoracic echocardiography showed severely depressed ejection fraction (EF) with severe secondary MR. Right heart catheterization confirmed a low cardiac index. Diuretics and inotropes were administered. Due to persistent hypotension, we could not wean inotropes. The patient was deemed high risk for surgery by the heart team, and a decision was made to proceed with TEER with MitraClip. Under transoesophageal echocardiography and fluoroscopic guidance, two MitraClips were deployed sequentially. The MR grade was reduced to two mild jets subsequently. The patient was weaned off inotropes and eventually discharged. At the 30-day follow-up, he was participating in physical activities such as golf. Discussion: Cardiogenic shock complicated by severe MR carries high mortality. With severe MR, the forward stroke volume is lower than the stated EF leading to poor organ perfusion. Inotropes and/or mechanical circulatory support devices are paramount for initial stabilization; however, they do not treat underlying MR. Transcatheter edge-to-edge repair with MitraClip has been shown to improve survival in CS patients with severe MR in observational studies. However, prospective trials are lacking. Our case demonstrates the utility of MitraClip to treat severe secondary MR refractory to medical therapy in a CS patient. The heart team must evaluate risks and benefits of this therapy in CS patients.
