title: Watchful waiting for severe mitral regurgitation.
abstract: Watchful waiting is an established treatment strategy for asymptomatic patients with severe organic mitral regurgitation. It is based on indications for surgery that are based on current European Society of Cardiology and American Heart Association/American College of Cardiology guideline recommendations, which are defined by symptom onset, impairment of left ventricular function, and left ventricular enlargement. Excellent outcome is achieved when patients are periodically followed with clinical and echocardiographic examinations and when surgery is performed in expert centers. The strategy is based on the recognition of mitral regurgitation at an early symptomatic stage, avoiding a delayed referral of these patients. There is an ongoing debate about whether surgery should be performed in asymptomatic patients with preserved ventricular function. Ultimately, decision-making needs to be individualized and to take individual patient-related factors and local resources (including the natural history of the disease, the risk of surgery, and the likelihood of successful mitral valve repair) into consideration to obtain an optimal outcome with medical and surgical management.
