- Abstract: We report a case of extracardiac rupture of the left Valsalva sinus aneurysm, which is an extremely rare and fatal lesion. The three drugs, clindamycin, ethambutol and rifampicin, had been administered for eleven years because of lung mycobacterium infection. An emergency surgery was performed because of cardiac tamponade. The left Valsalva sinus was entirely enlarged without an aneurysmal neck. The other Valsalva sinuses seemed to be almost normal. The aneurysmal wall adhered the pulmonary artery and the left atrium. The left descending and circumflex arteries independently originated from the aneurysmal wall. The left main trunk seemed to become a part of the aneurysmal wall. Additionally the intraoperative transesophageal echocardiography showed severe aortic regurgitation. The Bio-Bentall procedure was performed. The right coronary artery was reconstructed with the Carrel patch method and the saphenous vein grafts were anastomosed to the proximal portions of the left anterior descending and circumflex arteries, individually. On the thirty-third postoperative day, the patient was discharged uneventfully expect for the delayed sternal closure on the second postoperative day. Five and half years after surgy, the patient is living a normal life and rifampicin has been administered without any anticoagulation drugs.
