[Postoperative myocardial infarct after aorto-coronary bypass].

The incidence (4.3%) of myocardial infarction after aorto-coronary bypass vein graft procedures, and the mechanisms by which they occur, have been analysed in a series of 300 postoperative patients. Very careful case selection for surgery, extreme care in preserving the myocardium throughout the operation, and especially while the coronary anastomoses are being carried out, and attention to detail as they are done all contribute in varying degrees to the prevention of this complication. The particular clinical features and the natural history of this condition of post-operative infarction are recalled.
