Özet

© 2015 Clinics Cardive Publishing (Pty) Ltd.Introduction: The aim of this study was to determine the factors associated with postoperative atrial fibrillation (AF) in patients with left atrial (LA) myxoma Methods: Thirty-six consecutive patients with LA myxoma (10 men, mean age: 49.3 ± 15.7 years), who were operated on between March 2010 and July 2012. were included in this retrospective study. Pre-operative electrocardiograms and echocardiographic examinations of each patient were reviewed. Results: Postoperative AF developed in 10 patients, whereas there was no evidence of paroxysmal AF after resection of the LA myxoma in the remaining 26 patients. The patients who developed AF postoperatively were significantly older than those who did not develop AF (median: 61.5 vs 46 years; p = 0.009). Among the electrocardiographic parameters. only P-wave dispersion differed significantly between postoperative AF and non-AF patients (median. 57.6 vs 39.8 ins, p = 0.004). Logistic regression analysis revealed P-wave dispersion (OR: 1.11,95% CI: l.003-1.224,p-0.043)and age(OR: 1.13, 95% CI: l.OOI-l.278,p = 0.048) as independent predictors of postoperative AF in our cohort of patients. Conclusions: P-wave dispersion is a simple and useful parameter for the prediction of postoperative AF in patients with LA myxoma.
