The design of a saline\u2010irrigated tip (SIT) catheter (Thermo\u2010Cool\u2122, Cordis\u2010Webster) involves active cooling of the tip electrode, which allows creation of larger ablation lesions.<\/jats:p><jats:p> <jats:italic>Methods and Results:<\/jats:italic> Eight patients (<jats:styled-content>6 men, age 59 \u00b1 12 years<\/jats:styled-content>) in whom the clinical target VT (<jats:styled-content>cycle length 430 \u00b1 97 msec<\/jats:styled-content>) could not be ablated using a conventional 4\u2010mm tip RF ablation catheter underwent additional attempts to ablate this VT using a SIT catheter. Six patients had an old myocardial infarction, 1 patient had a dilated cardiomyopathy, and 1 patient had a structurally normal heart. Ablation of the clinical target VT using a SIT catheter was attempted from the left ventricle in 6 (septal, posterobasal, and inferior: 2 each) and from the right ventricle in 2 patients (both septal), by entrainment (<jats:styled-content>n = 6<\/jats:styled-content>), activation (<jats:styled-content>n = 1<\/jats:styled-content>), or pace mapping (<jats:styled-content>n = 1<\/jats:styled-content>). A mean of <jats:styled-content>6 \u00b1 5<\/jats:styled-content> (range 2 to 15) pulses were delivered. Target VT ablation was successful in 5 patients (63%). After successful ablation, at a mean follow\u2010up of <jats:styled-content>6.5 \u00b1 4<\/jats:styled-content> months and while taking antiarrhythmic drugs, all 5 patients were free of VT recurrences.<\/jats:p><jats:p> <jats:italic>Conclusion:<\/jats:italic> The clinical target VT could be ablated using a SIT catheter in 5 (63%) of the 8 patients in whom ablation using a conventional RF catheter was unsuccessful. In the 2 patients with septal VT, a biventricular approach to mapping and ablation was required.<\/jats:p>","DOI":"10.1046\/j.1540-8167.2001.00153.x","type":"journal-article","created":{"date-parts":[[2003,8,13]],"date-time":"2003-08-13T12:04:30Z","timestamp":1060776270000},"page":"153-161","source":"Crossref","is-referenced-by-count":17,"title":["Use of a Saline\u2010Irrigated Tip Catheter for Ablation of Ventricular Tachycardia Resistant to Conventional Radiofrequency Ablation: Early Experience"],"prefix":"10.1111","volume":"12","author":[{"given":"ASHISH","family":"NABAR","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"LUZ MARIA","family":"RODRIGUEZ","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CARL","family":"TIMMERMANS","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"HEIN J.
