Seventy-nine patients underwent repeat myocardial revascularization between March 1971 and January 1977. The initial procedure was performed at the St. Vincent Medical Center, Los Angeles, in 70 (2.0 percent) of 3,526 patients undergoing surgery for coronary arterial disease and in nine more patients was performed at other hospitals; the second operation followed the first procedure at an interval of from three weeks to 78 months. Five deaths (6 percent) occurred while patients were hospitalized, and six deaths (8 percent) occurred later. Two of the six later deaths were from noncardiac causes. Complications were not different from those that occurred during primary procedures. Thirty-six (60 percent) of 60 patients undergoing repeat surgery since 1973 did not receive any transfusions of blood during or after surgery. Of 48 patients followed-up for periods ranging from 12 to 70 months after the second operation, angina was completely relieved in 18 patients (38 percent), improved in 16 patients (33 percent), unchanged in 11 patients (23 percent), and worse in three patients (6 percent).
