“…Similar to our study, these studies support the hypothesis that CBP and CC times do not affect POAF, since there is no significant difference between the two surgical techniques in development of POAF [ 6 , 22 ] . However, Hashemzadeh et al [ 23 ] showed that the development of POAF was significantly reduced after off-pump CABG compared to on-pump CABG, and the conversion from POAF to a sinus rhythm was likelier in patients who underwent off-pump CABG. Similarly, some meta-analyses revealed lower rates of POAF in patients who underwent off-pump CABG [ 24 , 25 ] .…”

Introduction Many etiological factors affect the occurrence of atrial fibrillation after coronary artery bypass grafting. In this study, the relationship between cardiopulmonary bypass and cross-clamping times and the development of postoperative atrial fibrillation was examined. Methods All patients who underwent isolated coronary artery bypass grafting with the same surgical team in our clinic between September 2018 and December 2019 were prospectively included in the study, and their perioperative data were recorded. Results One hundred and three patients who met the specified criteria were included in the study. The median age was 62 (interquartile range: 54-71) years, and 82 (79.6%) were male. The patients were divided into two groups: those who developed atrial fibrillation and those who did not. Atrial fibrillation developed in 25 of 103 patients (24.3%). All patients underwent isolated coronary artery bypass grafting under standard cardiopulmonary bypass. The median duration of cardiopulmonary bypass was 72 (interquartile range: 63-97) minutes in those with atrial fibrillation and 82 (61-98) minutes in those without it, and there was no statistical difference (P=0.717). The median cross-clamping time was 40 (32.5-48) minutes in those with atrial fibrillation and 39.5 (30-46) minutes in those without it. Statistically, the relationship between cross-clamping time and atrial fibrillation was not significant (P=0.625). Conclusion Our study found no significant relationship between cardiopulmonary bypass and cross-clamping times and the incidence of postoperative atrial fibrillation. However, we believe that there is a need for large-scale and multicenter clinical studies on the subject.

Background: This study aimed to investigate the incidence of postoperative atrial fibrillation (POAF) in patients undergoing off-pump versus on-pump coronary artery bypass grafting (CABG) under cardiopulmonary bypass (CPB). Methods: A total of 3,197 consecutive patients (1,816 males, 1,381 females; mean age: 60.8 ± 9.8 years) with preoperative sinus rhythm who underwent CABG at a cardiovascular surgery clinic between November 2009 and March 2014 retrospectively were analyzed. Of the patients, 1,680 underwent on-pump and 1,517 underwent off-pump cardiac surgery. Data, including demographic characteristics, preoperative risk factors, preoperative medications, laboratory test results, postoperative data and complications, and mortality and morbidity rates, were recorded. Results: According to the multivariate analysis, the type of operation, number of anastomoses, right coronary artery or right coronary posterior descending artery graft, vasopressor therapy (epinephrine, norepinephrine), operation duration, age >60 years, hypertension, length of hospital stay >4 days, and obstructive sleep apnea syndrome (OSAS) were the independent predictors of POAF after CABG. Our study results suggest that on-pump CABG under CPB is correlated with POAF. Conclusion: We recommend using off-pump CABG in select cases to minimize the risk of POAF.

Background: Few studies have focused on new-onset postoperative atrial fibrillation in patients with hypertrophic obstructive cardiomyopathy who have undergone septal myectomy. Therefore, we investigated the incidence and prognosis effects of postoperative atrial fibrillation following septal myectomy in patients with hypertensive obstructive cardiomyopathy. Additionally, we investigated the relationship of estimated glomerular filtration rate and postoperative atrial fibrillation.Methods: Data from 300 patients with hypertrophic obstructive cardiomyopathy who underwent isolated surgical septal myectomy were collected from January 2012 to March 2018. Results: The overall incidence of postoperative atrial fibrillation during hospitalization was 22.67% (68 of 300 patients). Patients with postoperative atrial fibrillation were older (P<0.001), had lower preoperative estimated glomerular filtration rate (P<0.001), and a larger preoperative left atrial diameter (P=0.038) compared to patients without. The preoperative estimated glomerular filtration rate predicted postoperative atrial fibrillation with sensitivity and specificity of 0.824 and 0.578 (P<0.001), respectively. Multivariate regression analyses showed that age [odds ratio (OR) =1.090, 95% confidence interval (CI): 1.034-1.110], an New York Heart Association functional class ≥ III (OR =2.985, 95% CI: 1.349-6.604), hypertension (OR =2.212, 95% CI: 1.062-4.608), a history of syncope (OR =3.890, 95% CI: 1.741-8.692), and the preoperative estimated glomerular filtration rate (OR =0.981, 95% CI: 0.965-0.996) were independent risk factors associated in the development of postoperative atrial fibrillation. Survival analysis showed that the incidence of long-term cardiovascular events was higher in the patients with postoperative atrial fibrillation than that in the patients without the condition (P<0.001). Conclusions:The preoperative estimated glomerular filtration rate was a moderate predictor of postoperative atrial fibrillation after septal myectomy. Postoperative atrial fibrillation affected the early recovery and the long-term prognoses of patients with hypertrophic obstructive cardiomyopathy who underwent septal myectomy.
