Double orifice of the mitral valve (DOMV) is a rare anomaly often associated with other congenital malformations, especially with endocardial cushion defect. The case of a 36-year-old man with DOMV and no associated anomalies is reported here. Preoperative transthoracic echocardiography showed prolapse of the posterior mitral leaflet and moderate to severe regurgitation. The existence of the DOMV was not suspected, however. Intraoperative direct pericardial echocardiography clearly showed the orifice of the mitral valve to be divided into two openings by bridging tissue, indicating DOMV. No other cardiac anomalies were found. The preoperative diagnosis was mitral valve prolapse, and valvuloplasty was planned. DOMV was identified during openheart surgery, however, so valve replacement was performed instead of valvuloplasty. Postoperative course was uneventful, and the patient recovered and was discharged 43 days after surgery.
