This study sought to determine acute success rates and complication rates of ablation procedures for patients with VA in a Swiss tertiary care center. Methods: All patients who underwent ablation therapy for VT and PVC at the University Heart Center in Zurich, Switzerland, between March 2012 and April 2017 were included in this analysis. Results: A total of 120 patients underwent catheter ablation for VT and PVC (69 and 51, respectively). Seventy percent of patients were male, and the mean age was 55.3 years. The most common indication for ablation was high PVC burden (47.5%), followed by paroxysmal VT (38.3%), ICD shocks (23.3%), incessant VT (12.5%), electrical storm (7.5%), and syncope (3.3%). Acute success rates for VT and PVC ablations were 94.2% and 92.2%, respectively. Rates for complications (including major and minor) for VT and PVC were 10.1% and 7.8%, respectively. Complications occurred only in patients with structural heart disease; no complications were noted in structurally normal hearts. Conclusions: Our results suggest that catheter ablation for VT and PVC has high acute success rates with a reasonable risk for complications in the setting of tertiary care centers, comparable to those reported in other studies.<\/jats:p>","DOI":"10.3390\/jcm13082310","type":"journal-article","created":{"date-parts":[[2024,4,17]],"date-time":"2024-04-17T07:54:36Z","timestamp":1713340476000},"page":"2310","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Real World Data from Catheter Ablation of Ventricular Tachycardias and Premature Ventricular Complexes in a Tertiary Care Center"],"prefix":"10.3390","volume":"13","author":[{"given":"Christian","family":"Schlatzer","sequence":"first","affiliation":[{"name":"University Hospital of Zurich, 8091 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan","family":"Berg","sequence":"additional","affiliation":[{"name":"University Hospital of Zurich, 8091 Zurich, Switzerland"},{"name":"Department of Cardiology, Medical University Department, Kantonsspital Aarau Tellstrasse 25, 5001 Aarau, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4748-0158","authenticated-orcid":false,"given":"Firat","family":"Duru","sequence":"additional","affiliation":[{"name":"University Hospital of Zurich, 8091 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Corinna","family":"Brunckhorst","sequence":"additional","affiliation":[{"name":"University Hospital of Zurich, 8091 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1896-0803","authenticated-orcid":false,"given":"Ardan M.","family":"Saguner","sequence":"additional","affiliation":[{"name":"University Hospital of Zurich, 8091 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laurent M.","family":"Haegeli","sequence":"additional","affiliation":[{"name":"University Hospital of Zurich, 8091 Zurich, Switzerland"},{"name":"Department of Cardiology, Medical University Department, Kantonsspital Aarau Tellstrasse 25, 5001 Aarau, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"652","DOI":"10.1161\/01.CIR.0000138107.11518.AF","article-title":"Identification of the Ventricular Tachycardia Isthmus After Infarction by Pace Mapping","volume":"110","author":"Brunckhorst","year":"2004","journal-title":"Circulation"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2056","DOI":"10.1016\/j.hrthm.2014.07.012","article-title":"Catheter ablation of postinfarction ventricular tachycardia: Ten-year trends in utilization, in-hospital complications, and in-hospital mortality in the United States","volume":"11","author":"Palaniswamy","year":"2014","journal-title":"Hear.
