In a series of 4,522 consecutive patients who underwent aorta-coronary
bypass (ACB) with the saphenous vein at the Texas Heart Institute, 32 had a
second revascularization procedure. All patients were reoperated upon
because of recurrence of incapacitating angina. Reappearance of angina was
related to obstruction of the grafts alone in 6 patients, to the disease of
other arteries alone in 16, and to both sources in the remaining 10
patients. In 9 patients progression of the native coronary disease was
found, in 16 significant coronary obstructions had been left unbypassed at
the time of initial operation, and in the remaining 7 patients inadequate
indication and/or performance of revascularization was considered
responsible for the failure. Of the 31 survivors, 61 per cent experienced
complete relief of angina or were improved, whereas 39 per cent were
unimproved. Reoperation was more successful in relieving angina when
performed in patients with new lesions or with previously unbypassed
lisions than when done in patients with graft occlusion. Incidence of
myocardial infarction after the first and second procedure was similar (3
per cent). Reoperation was performed with a mortality rate of 3 per cent,
comparable to that of the original procedure, but relief of angina was not
achieved so consistently.
