Background: The early outcome of OPCAB is widely accepted to bring benefits to patient by reducing the complications of a cardiopulmonary bypass. The procedure is relatively new in the Philippines and is increasingly gaining popularity. It is the objective of this study to determine the midterm outcome of patients who underwent Off-pump coronary artery bypass.
Materials and Methods: From January 2001 to December 2002, medical records of patients from 3 centers who underwent pure OPCAB surgery were reviewed. Their demographic, peri-operative and postoperative data were collected. Patients were followed-up from a period of 12 to 30 months. It was done by interview through telephone and at the attending physician's clinic. Event-free survival and the association between the co-morbidities and cardiac events were determined using appropriate statistical analysis.
Results: A total of 68 patients were included in the study. Midterm outcome showed 5 patients with cardiac related events. Only one patient had repeat revascularization.
Conclusion: OPCAB is a safe procedure with promising results. however, greater number of subjects and loner follow-up period are needed to establish its superiority against the conventional CABG.
