The OT areas consist of the Right Ventricular Outflow Tract (RVOT), the Left Ventricular Outflow Tract (LVOT), the Aortomitral Continuity (AMC), the aortic cusps and the Left Ventricular (LV) summit. By definition, all OT PVCs will exhibit an inferior QRS axis, defined as positive net forces in leads II, III and aVF. Activation mapping using the contemporary 3D mapping systems followed by pace mapping is the cornerstone strategy of every ablation procedure in these patients. In this mini review we discuss in brief all the modern mapping and ablation modalities for successful elimination of OT PVCs, along with the potential advantages and disadvantages of each ablation technique.<\/jats:p>","DOI":"10.31083\/j.rcm2303103","type":"journal-article","created":{"date-parts":[[2022,3,18]],"date-time":"2022-03-18T09:30:40Z","timestamp":1647595840000},"source":"Crossref","is-referenced-by-count":13,"title":["Modern mapping and ablation of idiopathic outflow tract ventricular arrhythmias"],"prefix":"10.31083","volume":"23","author":[{"given":"Stylianos","family":"Dragasis","sequence":"first","affiliation":[{"name":"Arrhythmia Unit, Onassis Cardiac Surgery Center, 17674 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konstantinos","family":"Vlachos","sequence":"first","affiliation":[{"name":"Arrhythmia Unit, Onassis Cardiac Surgery Center, 17674 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"Frontera","sequence":"first","affiliation":[{"name":"Cardiac Arrhythmia Department, Humanitas Research Hospital IRCCS Rozzano, 20089 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Panagiotis","family":"Mililis","sequence":"first","affiliation":[{"name":"Arrhythmia Unit, Onassis Cardiac Surgery Center, 17674 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Athanasios","family":"Saplaouras","sequence":"first","affiliation":[{"name":"Arrhythmia Unit, Onassis Cardiac Surgery Center, 17674 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andromahi","family":"Zygouri","sequence":"first","affiliation":[{"name":"Arrhythmia Unit, Onassis Cardiac Surgery Center, 17674 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Erato","family":"Zymatoura","sequence":"first","affiliation":[{"name":"Arrhythmia Unit, Onassis Cardiac Surgery Center, 17674 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marianthi","family":"Kontonika","sequence":"first","affiliation":[{"name":"Arrhythmia Unit, Onassis Cardiac Surgery Center, 17674 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikolaos","family":"Kafkas","sequence":"first","affiliation":[{"name":"Department of Cardiology, KAT General Hospital of Attica, 14561 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Efremidis","sequence":"first","affiliation":[{"name":"Arrhythmia Unit, Onassis Cardiac Surgery Center, 17674 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konstantinos P.","family":"Letsas","sequence":"first","affiliation":[{"name":"Arrhythmia Unit, Onassis Cardiac Surgery Center, 17674 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2022,3,16]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","unstructured":"Cronin EM, Bogun FM, Maury P, Peichl P, Chen M, Namboodiri N, et al. 2019 HRS\/EHRA\/APHRS\/LAHRS expert consensus statement on catheter ablation.
