Although this arrhythmia is often self-limited and vanishes in about 24 hours upon surgery; a number of arrhythmias might ensue among which some might be really life-threatening. A multitude of therapeutic modalities have been proposed for the prevention of this arrhythmia and one of them is posterior pericardiotomy. This method has not been fully accepted by the peers yet and more studies are needed to prove its efficacy and benefits to the patients."n"nMethods: In this single-blind randomized clinical trial, done over a 2-year period from February 2009 to January 2011, the effects of posterior pericardiotomy were evaluated in 174 patients (87 the case and 87 the control groups) undergoing elective coronary artery bypass grafting (CABG). The case group underwent CABG with posterior pericardiotomy while the control group underwent CABG-only operation. The post-operative incidence of arrhythmia, especially atrial fibrillation, was assessed for a week using statistical methods."n"nResults: The prevalence of postoperative atrial fibrillations were fewer in the group undergoing CABG with posterior pericardiotomy compared with the CABG-only group (P<0.004)."n"nConclusion: Posterior pericardiotomy seems to reduce the incidence of atrial fibrillation following elective CABG; therefore, its application is suggested for elective CABGs.
