Treatment of degenerative mitral regurgitation in elderly patients

Advanced age is a common contraindication for cardiac surgery, particularly in high-risk patients with comorbidities, such as pulmonary and renal impairment, associated coronary artery disease, and neurological disorders. In elderly patients with degenerative mitral regurgitation who are not eligible for conventional surgical valve repair or replacement, percutaneous valve repair is emerging as a viable alternative therapeutic option. Nonsurgical and minimally invasive therapies for degenerative mitral regurgitation are of particular value in this subset of patients, because these interventions are associated with reduced perioperative mortality, clinical improvement, and faster recovery than is possible with surgical procedures. However, given that surgery remains the gold-standard treatment and should still be considered an option regardless of a patient's age, transcatheter mitral valve repair should be performed only in candidates who will gain the most benefit from it. The balance between the risks and benefits, and the value versus the futility of procedures to treat degenerative mitral regurgitation in elderly patients should be assessed by a specialized multidisciplinary care team. In this Review, we discuss the treatment options and indications for degenerative mitral regurgitation in elderly patients
