Abstract :Objectives: Atrial fibrilation insert ignore into journalissuearticles values(AF); develops from an arrhythmogenic ectopic focus, which triggers the vicious circle that creates arrhythmias. Arrhythmogenic foci are often located in the transition areas between the pulmonary veins and the left atrial endothelium. This study aims to compare the pulmonary vein anatomy of patients with and without AF using multidetector computed tomographic insert ignore into journalissuearticles values(MDCT); angiography and to evaluate the relationship between the presence of pulmonary vein variations and the development of AF. Methods: Seventy cases insert ignore into journalissuearticles values(38 males, 32 females); aged between 23 and 75 insert ignore into journalissuearticles values(mean age: 49.9 ± 13.3 years); were included in this study. This study consisted of 20 patients undergoing endovascular radiofrequency catheter ablation with AF and 50 participants insert ignore into journalissuearticles values(control); without AF. MDCT angiography examination was performed for the evaluation of pulmonary vein anatomy and variations. Results: Normal pulmonary vein anatomy was observed in 30% insert ignore into journalissuearticles values(n = 6); of the study group, 60% insert ignore into journalissuearticles values(n = 30); of the control group, and 51.4% insert ignore into journalissuearticles values(n = 36); of the total of both groups. Variation in pulmonary vein anatomy insert ignore into journalissuearticles values(accessory pulmonary vein or common ostium); was detected in 48.6% insert ignore into journalissuearticles values(n = 34/70); of the cases. The most common variation was the presence of accessory pulmonary vein insert ignore into journalissuearticles values(35.7%);. Common ostium was found to be the second most common variation insert ignore into journalissuearticles values(12.8%);. All common ostia were localized on the left side. Early branching of pulmonary veins was detected in 41 insert ignore into journalissuearticles values(58.5%); of 70 cases. Conclusions: Accesory pulmonary vein, common ostium and early branching are more frequently present in patients with AF.
