Özet
Introduction: Currently, there are no data regarding outcomes of the catheter ablation for structural ventricular tachycardia (VT) in T & uuml;rkiye. In this observational study, we aim to investigate cardiac outcomes of patients undergoing catheter VT ablation at a tertiary center in Turkiye. Methods: This was a retrospective observational study performed at a single university center. Patients with a confirmed ischemic or non-ischemic cardiomyopathy, undergoing structural VT ablation were included. Procedural and mid-term outcomes were analyzed. Results: A total of 124 patients were enrolled in the study. 54(43.5%) patients presented with an electrical storm. During the mean follow-up of 351 +/- 232 days 10(8.1%) patients experienced a recurrence. There was only one peri-procedural death and cardiac tamponade occurred in two patients.14(11.3%) patients died during the follow-up, most commonly due to a cardiovascular death. In the multivariate analysis only age >70 was found to be correlated with death during follow-up, with p =.008, HR = 4.923. Conclusion: A good acute success with low complications was observed in patients undergoing VT ablation for structural heart disease in a tertiary center in T & uuml;rkiye. Mid-term outcomes are comparable with international studies with no difference in VT recurrence in ischemic and non-ischemic patients. Similar to international studies, significant mid-term mortality was observed.
