The Effect of Posterior Pericardiotomy on the Risk of Supraventricular Arrhythmias after Off-Pump Coronary Artery Bypass Grafting (OPCABG)
Abstract
Aim. To evaluate the effectiveness of posterior pericardiotomy in reducing the risk of postoperative supraventricular arrhythmias in patients who underwent off-pump coronary artery bypass grafting.
Materials and methods. This study was conducted at the Republican Specialized Scientific and Practical Medical Center of Cardiology. The study included 220 patients with coronary artery disease who had indications for surgical intervention. The average age of the patients was 58,6±7,2years, including 31 women and 189 men. The patients were randomly divided into 2 groups. 110 patients in the first group underwent posterior pericardiotomy, and 110 patients in the second group did not undergo this procedure. All patients underwent Holter ECG monitoring (HMECG) 5 days and 24 hours before the surgery.
Results. According to the monitoring results, 48 patients developed POAF after off-pump coronary artery bypass grafting, which accounted for 21.8% of the total number of patients. Analysis of clinical and anamnestic parameters showed the following. The groups did not differ significantly in age and gender (Table 1). Arterial hypertension was more common in the group with POAF - 95.1% compared to 44.3% in the group without POAF (X2 = 29.9; p < 0.001). Also, patients in the main group were more likely to be obese than in the group without POAF (X2 = 7.1; p = 0.008). Diabetes mellitus (DM) was also significantly more common in patients with POAF - 68.5% compared to 30.5% (X2 = 17; p < 0.001).
Conclusion. According to our results, 21.8% of patients after off-pump CABG had POAF. The main reasons for this were the patient’s age, left atrial dilation, comorbidities, and myocardial fibrosis. It can be concluded that posterior pericardiotomy significantly reduces the incidence of supraventricular arrhythmias. It also reduces the incidence of cardiac tamponade, thromboembolic complications, and the length of stay in the intensive care unit and rehabilitation unit, which saves hospital resources.
