AbstractWe reviewed ten cases who underwent aortic root replacement after operation for the ascending aorta and/or aortic valve. As initial operation, aortic valve replacement (AVR) was performed in five patients, replacement of the ascending aorta in two, original Bentall operation in two, and entry closure and suspension of the aortic valve in one. At reoperation, three patients were diagnosed as aneurysm of the ascending aorta, two were annulo-aortic ectasia, and one was acute aortic dissection, chronic dissecting aneusym, pseudoaneurysm of the ascending aorta, prosthetic valve endocarditis, and massive aortic regurgitation. Aortic root replacement was performed using mechanical valved composite graft in all cases. One patient who underwent repeat aortic root replacement for prosthetic valve endocarditis was died of septemia and ventricular fibrillation. Five patients had nine complications (two low output syndrome, respiratory failure and cerebral infarction, one gastrointestinal bleeding, septemia and ventricular fibrillation). In conclusion, aortic root replacement after operation for the ascending aorta and/or aortic valve was performed with acceptable morbidity and mortality.
