Abstract :Objectives: In patients who do not respond to medical treatment with idiopathic premature ventricular complex insert ignore into journalissuearticles values(PVC);, catheter ablation is performed using the electroanatomic mapping insert ignore into journalissuearticles values(3D EAM); system for ablation. The aim of this study is to evaluate the acute and long-term success of patients and the procedural features and complication results associated with PVC localization in patients who underwent catheter ablation in our center. Methods: Two hundred seventeen patients who underwent activation mapping and ablation using 3D EAM for PVC were included in the study. Patients were followed up for acute procedure success, periprocedural complications, and six-month long-term recurrence. In addition, these parameters, PVC’s were evaluated in three groups as right ventricular outflow tract insert ignore into journalissuearticles values(RVOT);, coronary cusp and rare localized origin, and clinical outcomes and interventional variables related to the success of the PVC’s location were compared. Results: In our study, the mean age of the patients was 43 ± 12.1 years and the female gender ratio was 37.8%. When catheter ablated PVC foci were evaluated, it is seen that 81 insert ignore into journalissuearticles values(37.3%); were from RVOT and 56 insert ignore into journalissuearticles values(25.8%); were from coronary cusp. In addition, 6 insert ignore into journalissuearticles values(2.8%); were aortomitral continuity, 22 insert ignore into journalissuearticles values(10.1%); were left ventricular summit/epicardial, 17 insert ignore into journalissuearticles values(7.8%); were parahisian, and total 80 insert ignore into journalissuearticles values(36.8%); were rare localized PVCs. Acute procedure success was 92.6% and long-term procedure success was 83% in all cases. When the patients in our study were analyzed according to their PVC locations and procedure successes, those with rare localization compared to those with RVOT and coronary cusp origin were 66 insert ignore into journalissuearticles values(87.5%);, 79 insert ignore into journalissuearticles values(96.3%);, and 53 insert ignore into journalissuearticles values(94.6%);; respectively insert ignore into journalissuearticles values( p = 0.03); and long-term successes were 58 insert ignore into journalissuearticles values(72.5%);, 73 insert ignore into journalissuearticles values(90.1%);, and 49 insert ignore into journalissuearticles values(87.5%);; respectively insert ignore into journalissuearticles values( p < 0.05);. Long-term transaction success was lower. Conclusions: Frequent PVCs can be treated with electroanatomic mapping and radiofrequency ablation with high success rate and low complication rate. Patients with RVOT and coronary cusp-derived PVC had a high acute and long-term success rate, while success rates were lower in rare localized PVCs from epicardial/summit, papillary muscle, parahisian and tricuspid-mitral anulus.
