Objective:
To evaluate the safety and efficacy of intermittent aortic cross-clamping technique for myocardial preservation during coronary artery bypass grafting and to compare the results with other published series using the same technique.
Design:
An institution-based analytical study.
Place And Duration Of Study:
Study was carried out from July 1995 to December 1997 at Punjab Institute of Cardiology, Lahore.
Patients And Methods:
The data of 100 consecutive patients were analyzed who had coronary artery bypass grafting without cardioplegia using intermittent aortic cross-clamping. All the patients who had emergency or concomitant major surgery, reoperations, and aortic disease with calcification were excluded from this study.
Results:
Despite minor complications there was no mortality, no rhythm disturbance or perioperative infarction. Inotropic support was needed in 8% of patients.
Conclusion:
Our results compared favourably with other published series using the same technique. These results provide re-assurance that intermittent aortic cross-clamping provides excellent myocardial protection and operative conditions for primary coronary artery bypass. It also provides a simple and safe option for myocardial protection during coronary artery bypass grafting.
