Posterior pericardiotomy reduces the incidence of supra-ventricular arrhythmias following coronary artery bypass surgery.
A prospective study of 100 patients undergoing coronary artery bypass surgery was performed to demonstrate the effectiveness of a posterior pericardiotomy in reducing the incidence of pericardial effusions and, consequently, reducing the incidence of supraventricular arrhythmias in the post-operative period. Pericardial effusion occurred in 4 of 50 patients following a posterior pericardiotomy, whereas effusion occurred in 20 of 50 patients in whom a pericardiotomy was not created (P < 0.0005). Supra-ventricular arrhythmias occurred in 4 patients in the pericardiotomy group and 18 in the group treated without pericardiotomy (P < 0.005). No complications resulted from this procedure. We conclude that pericardiotomy is a simple, safe and effective method for reducing the incidence or pericardial effusion and thereby post-operative supra-ventricular arrhythmias.
