A double aorto-coronary bypass procedure performed in 2 cases, one with a Prinzmetal`s variant angina and the other with an unstable angina, is presented. The patient with a Prinzmetal`s angina who had a high-grade obstruction of the left anterior descending and the right coronary system showed a marked postoperative improvement with complete disappearance of anginal pain. The other patient with unstable angina had obstruction of the left anterior descending as well as a marginal branch of the left circumflex artery. Following bypass of these vessels, the patient did well during the immediate postoperative period. However, he developed hypotension in the recovery room and died 6 hours postoperatively, in spite of an intensive effort at resuscitation. The most likely cause of death in this patient is a myocardial infarction.
