Abstract :Objective: We intended to report our institutional experience with ventricular tachycardia insert ignore into journalissuearticles values(VT); ablation in patients with structural heart disease. Patients and Methods: A total of 36 consecutive patients insert ignore into journalissuearticles values(31 male, age: 62.8 ± 13.2 years); who had undergone VT ablation in our institution between 01.01.2017 and 01.05.2019 were included in the analysis. Results: A total of 27 patients with the diagnosis of ischemic cardiomyopathy and 9 patients with the diagnosis of nonischemic cardiomyopathy had undergone VT ablation. VT ablation was successful in 32 insert ignore into journalissuearticles values(88.9%); patients. There were no major procedural complications; however, one patient with ischemic cardiomyopathy died 48 hours after the procedure because of post-ablation cardiogenic shock. Another patient with unsuccessful VT ablation died during hospitalization due to electrical storm. Endocardial ablation was performed in 23 insert ignore into journalissuearticles values(63.9%); patients and epicardial or combined endocardial and epicardial ablation was performed in 13 insert ignore into journalissuearticles values(36.1%); patients. Substrate ablation was the dominant strategy in 29 insert ignore into journalissuearticles values(80.6%); patients whereas activation mapping and isthmus ablation was performed in 7 insert ignore into journalissuearticles values(19.4%); patients. Conclusion: Our experience confirms the effectiveness and safety of VT ablation in patients with structural heart disease who are resistant to medical therapy and/or who receive recurrent implantable cardioverter-defibrillator shocks.
