Abstract

Background: Atrial fibrillation (AF) is the most prevalent arrhythmia occurring after cardiac surgery. The occurrence of postoperative AF (POAF) significantly affects patient outcomes, leading to increased morbidity, mortality, and hospital readmission rates. The incidence of POAF following total arterial coronary artery bypass grafting remains a subject of ongoing debate. This study seeks to evaluate the occurrence of early postoperative arrhythmias in patients undergoing total arterial revascularization.

Methods: We studied a cohort of 50 patients who underwent total arterial revascularization at the Cardiothoracic Surgery Department of Benha University Hospitals between October 2023 and October 2024. Data were collected preoperatively and postoperatively, encompassing demographic information, laboratory results, and both intraoperative and postoperative parameters.

Results: The average age of the study population was 52.5 years, with a predominance of male patients. The incidence of postoperative arrhythmias was recorded as follows: 6% for self-contained AF, 6% for uncontrolled AF, 2% for ventricular fibrillation, and 4% for premature ventricular contractions. The mean duration of bypass was 154.9 minutes, and the average length of stay in the intensive care unit (ICU) was 2.1 days. Postoperative complications included wound infections in 28% of patients, and the mortality rate was 4%.

Conclusions: Early postoperative arrhythmias pose a significant concern following total arterial revascularization. Identifying and managing risk factors associated with these arrhythmias could enhance patient outcomes, decrease complications, and ultimately contribute to improved survival and quality of life for individuals undergoing cardiac surgery.
