Our early results of isolated coronary artery bypass grafting: A case series of the first 100 patients in a newly established heart center

Abstract

Objective: In this study, we aimed to investigate the early results of the first 100 patients who underwent isolated elective coronary artery by-pass surgery because of coronary artery disease in our clinic. Methods: The first 100 patients who underwent isolated elective coronary artery by-pass surgery between October 2016-January 2018 were included. İn the study routine blood tests, echocardiography, electrocardiography, chest X-ray, carotid-vertebral artery doppler ultrasound, pulmonary function tests were performed and nasal culture was obtained preoperatively. Euroscore II scoring system was used for calculating the mortality risk. All operations were performed under intrathoracic general anesthesia. Using median sternotomy approach, ascending aortic cannulation, unicaval venous cannulation, intermittent antegrade cold blood cardioplegia and under mild hypothermia cardiopulmonary by-pass were performed. Results: Median age was 58 years and 35% (n=35) of the patients were female. Most common preoperative risk factors were hypertension (HT) (50%; n=50) and smoking (42%; n=42). Mean cardiopulmonary by-pass time was 70±13 minutes, mean cross-clamp time was 40±16 minutes, mean number of revascularized coronary arteries was 3.4±1.0. Postoperative atrial fibrillation was detected in 22% (n=22) of the patients, and all patients were converted to sinüs ritm with medical treatments. In hospital mortality was 2% (n=2). Conclusion: Surgical treatment of isolated coronary artery disease, especially in low-risk patient group, remains in the current treatment guidelines with low mortality and morbidity rates. © Istanbul Medeniyet University Faculty of Medicine.
