  • Title: Myocardial preservation with intermittent aortic cross-clamping technique during coronary artery bypass grafting.
    Author: Hussain S, Zaman H, Ahmed M.
    Journal: J Coll Physicians Surg Pak; 2003 Jun; 13(6):309-12. PubMed ID: 12814525.
    Abstract:
    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.
