A total of 83 bypasses were studied. Angiographic results demonstrated occlusion in 3 of 24 bypass of internal mammary artery placed in the anterior descending artery, 2 in the right coronary artery, 1 in the posterolateral of the circumflex and 1 in the first diagonal branch, with a total occlusion average of 8.4% within the first 8 days. We found a good correlation between the coronarographic angiograms and the positivity or negativity of the echo-electrocardiographic tests, during atrial pacing. We believe that this simple method could be done routinely in all the patients after coronary surgery, to decide the need of a new coronary angiogram. Furthermore, this study shows that the occlusion of a single coronary bypass does not produce myocardial infarction, detectable by enzymatic measures or by resting EKG. This method also detects the early post-operatory sinus sick syndrome.
