Transcatheter mitral valve repair with a mitraclip for severe mitral regurgitation in a patient on hemodialysis

Abstract

A 55-year-old male patient undergoing hemodialysis (HD) had shortness of breath, New York Heart Association (NYHA) class IIm (moderate limitation of physical activity) due to chronic heart failure. His past medical history was remarkable for chronic heart diseases and severe functional mitral regurgitation (MR), with an ejection fraction of only 33%. The cardiologist considered this severe MR as the cause of his symptom. Due to the multiple comorbidities and low cardiac function, transcatheter mitral valve repair (TMVR) using a MitraClip was selected as an alternative to surgery. TMVR with MitraClip was successfully performed. Postoperatively, the degree of MR decreased from severe to trivial, with an obvious improvement in symptoms to NYHA class I. He was discharged without any postoperative complications. TMVR with MitraClip is an effective nonsurgical treatment for mitral valve disease in HD patients with multiple comorbidities.
