A 58-year-old asymptomatic and otherwise healthy woman presented for surgical evaluation after echocardiography revealed severe mitral valve regurgitation (MR). She had a family history of MR and was being followed by her primary care doctor for a murmur. Transthoracic echocardiography (TTE) demonstrated severe MR due to bileaflet prolapse, Barlow's disease, a left atrial dimension of 44 mm, a left ventricular end systolic dimension of 36 mm, and a preserved ejection fraction. Mitral annular calcification (MAC) was also identified. After careful evaluation we believed that the extent of the MAC in this patient could be handed with the robotic technique as we have done before. There was no other significant valvular disease and the patient did not have coronary disease or arrhythmias.
