During a mean follow-up of 16 \u00b1 5 months, 3 patients in the conventional group had recurrences, compared with none in the contact force group. Complications occurred only in the conventional group (one steam pop; 2 ablations suspended because of significantly increasing impedance). In the contact force group, the median contact force during ablation was 10 g (interquartile range, 7\u201314 g). Times for overall procedure (36.9 \u00b1 5 min), fluoroscopy (86.3 \u00b1 22.7 s), and ablation (60.3 \u00b1 21.4 s) were significantly shorter in the contact force group than in the conventional group (46.2 \u00b1 6.2 min, 107.7 \u00b1 30 s, and 88.7 \u00b1 32.3 s, respectively; P<\/jats:italic> <0.001). In the contact force group, cases with a force-time integral <560 gram-seconds (g-s) had significantly longer procedure and fluoroscopy times (both P<\/jats:italic> <0.001) than did those with a force-time integral \u2265560 g-s.<\/jats:p>\n These findings suggest that ablation of premature ventricular contractions originating from the right ventricular outflow tract with an irrigated contact force\u2013sensing catheter instead of a conventional catheter shortens overall procedure, fluoroscopy, and ablation times without increasing risk of recurrence or complications.<\/jats:p>","DOI":"10.14503\/thij-17-6441","type":"journal-article","created":{"date-parts":[[2020,2,21]],"date-time":"2020-02-21T19:49:05Z","timestamp":1582314545000},"page":"3-9","source":"Crossref","is-referenced-by-count":8,"title":["Benefit of Contact Force\u2013Guided Catheter Ablation for Treating Premature Ventricular Contractions"],"prefix":"10.14503","volume":"47","author":[{"given":"Ziming","family":"Zhao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaowei","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lianjun","family":"Gao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yutao","family":"Xi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qi","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong","family":"Chang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xianjie","family":"Xiao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Cheng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanzong","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yunlong","family":"Xia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaomeng","family":"Yin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"5628","reference":[{"issue":"6","key":"i1526-6702-47-1-3-b1","series-title":"J Cardiovasc Electrophysiol","first-page":"509","article-title":"Determinants of lesion size during radiofrequency catheter ablation: the role of electrode-tissue contact pressure and duration of energy delivery","volume":"2","year":"1991","unstructured":"Haines\n DE.\n \n \n Determinants of lesion size during radiofrequency catheter ablation: the role of electrode-tissue contact pressure and duration of energy delivery.
