Physiologists could keep animals alive with an open chest long before surgeons set about doing the same thing in patients. Why was there not an orderly transfer of knowledge and technique?

In 12 patients who had had composite replacement of the aortic valve and ascending aorta, infective endocarditis developed 2 months to 17 years after operation. Six patients had mechanical valves and 6 had biological ones (four homograft and two porcine valves). All patients needed operation because of shock, heart failure, persistent sepsis in spite of adequate antibiotic therapy, or the development of a paravalvular false aneurysm. ⋯ Operative survivors were followed up from 3 to 156 months (mean, 42 months). One patient died 35 months postoperatively due to bleeding complications of anticoagulation; 1 patient suffered a cardiac arrest at home 2 months after operation, sustained permanent cerebral damage, and died 4 months later. The remaining patients are asymptomatic from the cardiovascular viewpoint.(ABSTRACT TRUNCATED AT 250 WORDS)
