Aortic valve replacement with frozen irradiated homografts. An 18-year experience.

Between May 1968 and April 1981, 339 patients underwent isolated aortic valve replacement using frozen irradiated homografts. All the operations were carried out by the same surgeon (EJMW) using the same technique. Thirty-two patients were lost to follow-up at various stages and the long-term results of the remaining 307 patients are reported. Two hundred and thirty-four were males and 73 females. Their ages ranged between 10 and 75 years, with a mean age of 53. The dominant lesion was aortic stenosis in 195 cases (63.5%), aortic regurgitation in 68 (22.1%), and mixed aortic valve disease in 44 (14.3%). Early mortality was 8.8% and late mortality during the 5-18 year follow-up period was 49.6%. Re-operations for homograft failure were carried out in 112 patients (40%), with an early mortality of 25%. The results are compared with those of other major series using antibiotic sterilized homograft valves.

Distal internal mammary artery (IMA) with retrograde flow for coronary artery grafting.

A case in which the right distal internal mammary artery (IMA) was used to graft the posterior descending branch of the right coronary artery is presented. The retrograde blood flow at dissection was 60 ml per minute, no electrocardiographic signs of myocardial ischemia were detected postoperatively. The patient is well and fully active 6 months after surgery.

Late results of mitral valve replacement using unstented antibiotic sterilised aortic homografts.

Three hundred and seventy nine patients who had undergone mitral valve replacement using unstented antibiotic sterilised aortic homografts were followed up for 52 to 138 months (mean 102 months). Patients requiring additional aortic valve replacement were excluded. The commonest cause was rheumatic heart disease (321 patients). There were 37 early deaths (9.8%) and 97 late deaths (28%). The actuarial survival of operative survivors was 83% at three years, 75% at five years, and 55% at nine years. Technical valve failure occurred in six patients (1.6%), infective endocarditis in 19 (5%), and degeneration of the valve in 43 (12.5%). The cumulative probability of freedom from endocarditis was 96% at three years, 94% at five years, and 91% at nine years, while that of freedom from valve degeneration was 97% at five years and 48% at 10 years. There were no early embolic episodes, but late embolism occurred in five patients (1.5%).
