To investigate the procedural efficiency, efficacy, and safety of high-power, short-term radiofrequency ablation delivered by the SmartTouch Surround Flow (STSF) catheter for paroxysmal atrial fibrillation (AF). Methods. We retrospectively analyzed a total of 72 patients who were admitted with paroxysmal AF, and who underwent radiofrequency catheter ablation (RFCA) for the first time. Of these patients, 36 cases underwent low-power, long-duration (LPLD, (30\u201335\u2009W\/20\u201340\u2009s) pulmonary vein isolation (PVI) delivered by an SmartTouch (ST) catheter (control group), and the other 36 cases underwent high-power, short-duration (HPSD, (45\u201350\u2009W\/10\u201320\u2009s) PVI delivered by a STSF catheter (study group). The baseline data, duration of PVI, procedural time, fluoroscopy time, the rate of first-pass isolation, irrigation perfusion, eschar and steam pop occurrences, intraoperative complications, and the rate of stable sinus rhythm maintenance following a blanking period of three months were analyzed between the two groups. Results. The isolation time of bilateral PVI and procedural time in the study group were markedly less than in controls (<jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>p<\/a:mi>\n                        <a:mo>&lt;<\/a:mo>\n                        <a:mn>0.01<\/a:mn>\n                     <\/a:math>\n                  <\/jats:inline-formula>). The rate of first-pass isolation in the study group was significantly higher than in the control group (95.8% vs. 84.7%, <jats:inline-formula>\n                     <c:math xmlns:c=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\">\n                        <c:mi>p<\/c:mi>\n                        <c:mo>=<\/c:mo>\n                        <c:mn>0.023<\/c:mn>\n                     <\/c:math>\n                  <\/jats:inline-formula>), while the fluid perfusion in the study group was approximately 20% less than that in the control group (767\u2009\u00b1\u2009171 vs. 966\u2009\u00b1\u2009227\u2009ml, <jats:inline-formula>\n                     <e:math xmlns:e=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M3\">\n                        <e:mi>p<\/e:mi>\n                        <e:mo>&lt;<\/e:mo>\n                        <e:mn>0.001<\/e:mn>\n                     <\/e:math>\n                  <\/jats:inline-formula>). We observed no severe complications in any patients. The rate of freedom from AF recurrences following a blanking period of three months showed a tendency to be higher than in controls (93.9% vs. 87.1%, <jats:inline-formula>\n                     <g:math xmlns:g=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M4\">\n                        <g:mi>p<\/g:mi>\n                        <g:mo>=<\/g:mo>\n                        <g:mn>0.348<\/g:mn>\n                     <\/g:math>\n                  <\/jats:inline-formula>). Conclusions. The HPSD strategy delivered by the STSF catheter was superior to conventional LPLD ablation through the ST catheter with respect to efficiency, acute procedural effectiveness, short-term safety, and the risk of heart failure in patients with paroxysmal AF.<\/jats:p>","DOI":"10.1155\/2022\/6009275","type":"journal-article","created":{"date-parts":[[2022,8,8]],"date-time":"2022-08-08T20:35:09Z","timestamp":1659990909000},"page":"1-8","source":"Crossref","is-referenced-by-count":3,"title":["Procedural
