title: Incidence of atrial fibrillation after extrapleural pneumonectomy vs. pleurectomy in patients with malignant pleural mesothelioma.
abstract: Extrapleural pneumonectomy (EPP) and pleurectomy are the surgical procedures for the treatment of pleural mesothelioma. However, EPP increases the risk for postoperative atrial fibrillation (AF). We conducted a retrospective chart review of 130 patients who underwent EPP or pleurectomy. Seventy patients (excluding three patients with a prior history of AF) underwent EPP and 57 patients underwent pleurectomy. The mean ages were 60+/-11 and 63+/-13 years, and the male to female ratios were 50/20 and 44/13, respectively. Postoperative AF was observed in 45 patients with 36 (51%) of these cases occurring after EPP and 9 (17%) after pleurectomy (P<0.0001). There were no significant differences between the two treatment groups for gender, age, side of affected lung, preoperative heart rate, history of beta-blocker use, coronary heart disease, and chronic obstructive pulmonary disease. Through logistic regression, EPP (OR=7.1, 95% CI: 2.9, 17.8) and age over 65 years (OR=2.9, 95% CI: 1.2, 6.8) were found to be risk factors for AF. We conclude that EPP vs. pleurectomy and age over 65 years are risk factors for postoperative AF. The increased odds of having AF after EPP could be due to right heart stress caused by pneumonectomy.
