Background This study aimed to investigate the predictive significance of C‐reactive protein/albumin ratio for postoperative atrial fibrillation occurrence in patients who were underwent coronary artery bypass graft surgery. Methods Among 830 patients who underwent coronary artery bypass grafting with cardiopulmonary bypass between January 2016 and February 2020, 137 patients with no prior arrhythmia history were included in this cross sectional study. Results One hundred and thirty‐seven (16.5%) patients developed atrial fibrillation in postoperative period. Patients who experienced postoperative atrial fibrillation were more likely to be older but displayed similar rates of diabetes mellitus, hypertension, hypercholesterolemia, cerebrovascular disease, peripheral vascular disease and chronic obstructive pulmonary disease. For prediction of postoperative atrial fibrillation development, diagnostic odds ratio (OR) and positive likelihood ratio of C‐reactive protein/albumin ratio value (OR: 1.854; confidence interval [CI]: 1.598‐2.142; P < .001) was higher than serum C‐reactive protein and albumin levels. (OR: 1.159; CI: 1.115‐1.201; P < .001; OR: 0.438; CI: 0.258‐0.865; P < .001, respectively). Which means that C‐reactive protein/albumin ratio may detect postoperative atrial fibrillation development better C‐reactive protein itself. Conclusion Based on our results, patients who developed postoperative atrial fibrillation after coronary artery bypass grafting had significantly higher preoperative C‐reactive protein/albumin ratio levels than patients who remained in normal sinus rhythm in the postoperative period. Also, higher C‐reactive protein/albumin ratio value was one of the independent predictive factors for postoperative atrial fibrillation. Therefore, we concluded that evaluating preoperative C‐reactive protein/albumin ratio value might provide early identification of patients with high risk for postoperative atrial fibrillation.

Background: Aortic neo-cuspidization (AVNeo) procedure has been adopted by limited centers with the publication of the mid-long term successful results. The aim of this study was to present initial experience of the AVNeo procedure of a single center. Methods: The medical records of 24 patients who underwent AVNeo with or without concomitant cardiac surgery between February 2019 and February 2021 at our tertiary hospital were scanned retrospectively. Results: The mean age of patients was aged 58.21 ± 13.14 years and 16 (66.7%) of them were men. 16 patients were operated on for aortic stenosis (66.67%). Morphology of the aortic valve was tricuspid in 21 (87.5%) and bicuspid in 3 (12.5%) of the patients. Additional cardicac surgery was performed in 13 (54.17%) patients. No patients needed reoperation for bleeding, pacemaker implantations, conversion to classical prosthetic aortic valve replacement, or infective endocarditis. Two patients died due to non-cardiac reasons. Preoperative peak and mean aortic valve pressures improved significantly at 1 st and 6 th months (

Introduction: Partial pulmonary venous return anomalies (PPVRA) were not considered as a good candidate for robotic surgery in early time of robotic cardiac surgery. In this study, we present our experience in patients undergoing robotic atrial septal defect (ASD) and PPVRA surgery.Methods: Between November 2014 and January 2020, data of 21 patients underwent robotic ASD with PPVRA was collected. Inclusion criterion was presence of right-sided PPVRA with ASD. All operations were performed robotically. Results:The mean age of patients was 26.7 � 10.3 years. Seventeen patients (81%) had superior-caval ASD with supracardiac PPVRA and double-patch technique was used. Four patients had inferior-caval ASD with intracardiac PPVRA and singlepatch technique was preferred. Cross-clamp time and cardiopulmonary bypass time were 92.8 � 29.6 and 127.8 � 38.1, respectively. There was no mortality. One patient had atrioventricular-block and required pacemaker. Conclusion:Robotic repair of ASD with PPVRA is feasible and effective method as an alternative to conventional surgery.
