The new St. Jude Medical aortic valve graft prosthesis was evaluated for composite graft replacement of the aortic root in 32 patients at three institutions. This study was performed in conformity with the Japanese Drugs, Cosmetics and Medical Instruments Act. The grafts were preclotted with blood of serum albumin: coronary artery reconstruction was performed employing the classical Bentall procedure (4 cases), Cabrol's procedure (14 cases), the interposition graft technique (8 cases) or the button technique (6 cases); concomitantly the aortic arch was replaced in one patient, and the mitral valve was replaced in two patients. One early death (3%) occurred as the result of shock sustained prior to establishing cardiopulmonary bypass. Postoperative complications included perivalvular leakage (one case), perioperative myocardial infarction (two cases), hepatitis (one case). There were no late deaths and no complications related to the SJM valve graft prosthesis. The SJM valve graft prosthesis is a safe and reliable prosthesis for use as a composite graft replacement of the aortic root.

From May 1975 to August 1991, 90 patients (56 males and 34 females) underwent Bentall's operations or its modified technique. In our modified technique the coronary ostium is cut out like a button and anastomosed to the aortic graft and aortic grafts are not wrapped by the aortic wall. Preoperative diagnoses were AAE (25 patients, 28%), Stanford type A dissection (19, 21%), Marfan's syndrome (16, 18%), aortitis syndrome (12, 13%), AR+ascending aortic aneurysm (6, 7%), syphilitic aortitis (5, 6%), AS+ascending aortic aneurysm (3, 3%), Valsalva's sinus aneurysm (2, 2%) and other diseases (2, 2%). The hospital mortality rate was 17% (15/90) for all cases. The hospital mortality for aortic dissection (37% (7/19)) and reoperation cases (75% (3/4)) were very high. There were 10 cases of late death and the 10 year actuarial survival rate was 66.3%. Among 11 cardiovascular events which occured in the late phase, 5 were dissection at other aortic sites in the type A dissection and Marfan syndrome cases, and 3 were pseudoaneurysm formation at the site of coronary or the aortic anastomosis in the aortitis syndrome cases, and a detachment of the composite graft in the Marfan's syndrome cases. The 10-year event-free rate was 92.0% for non-specific AAE, 68.8% for aortitis syndrome, 61.9% for Marfan's syndrome and 47.3% for Stanford type A dissection. Non-specific AAE had excellent long-term results, but Marfan's syndrome and dissection had poor results. The button technique for coronary reconstruction is effective for all cases and its long term results are good, but, even with this technique, coronary pseudo-aneurysm occured in cases of aortitis syndrome.

A 13-month-old girl (BW 4476g) with Taussig-Bing malformation was successfully treated by anterior intraventricular tunnel repair (Patrick-McGoon method). She had large subpulmonary malalignment ventricular septal defect with extreme inflow extension with anteroposterior relationship of the great arteries. Coronary arterial anatomy was a very rare type in that LAD branching from RCA originated from right facing sinus was running just anterior to the aorta and coronary relocation would result in straining and obstructing LAD. Intraventricular tunnel through the VSD to the aorta was tailored by use of a double velour Dacron conduit (14mm in diameter) and inflow extension of VSD was partly closed with a separate flat Dacron patch. LVOTO was not found on echocardiography and good clinical results were obtained at 11 months postoperatively.
