[Management of intraoperative systolic anterior motion of the mitral valve after valve plasty: a case report].
We report a case of intraoperative systolic anterior motion (SAM) of the mitral valve after mitral valve plasty (MVP). A 53-year-old man underwent MVP for mitral regurgitation (MR). MVP was carried out uneventfully. We weaned the patient from cardiopulmonary bypass (CPB) with continuous administration of catecholamines and a vasodilator. However, after the weaning from CPB, transesophageal echocardiography (TEE) detected moderate MR with left ventricular outflow tract obstruction (LVOTO) due to SAM. LVOTO and SAM gradually disappeared after the reduction of catecholamines and volume loading. He was transferred to the intensive care unit postoperatively and extubated 18 hours after operation. Transthoracic echocardiography after operation revealed disappearance of MR. He was discharged from the hospital on postoperative day 15 without complications. We successfully managed MR with LVOTO due to SAM by reduction of catecholamines and volume loading.
