Her electrocardiography (ECG) demonstrated ventricular pre-excitation combined with atrial fibrillation. The polarity of the delta waves in leads V5, V6, I, and aVL were positive and negative in leads V1, III, and aVF, suggesting that the accessory pathway (AP) was located on the right posterior free wall. She did not want to take any medicine to prevent the tachycardia. Moreover, the shortest pre-excited RR interval during the atrial fibrillation was 200 ms, so we decided to ablate the AP without fluoroscopy. An electrophysiology study was performed with guidance of a 3-dimension (3D) navigation system and intracardiac echocardiography (ICE). We ablated the right free wall AP without fluoroscopy. A follow-up ECG no longer exhibited any delta waves. Even in the early period of pregnancy, catheter ablation might be performed safely using ICE and a 3D navigation system without fluoroscopy. Therefore, it could more often be considered as a therapeutic option in pregnant women without concern for radiation exposure.<\/jats:p>","DOI":"10.31083\/j.rcm.2020.02.46","type":"journal-article","created":{"date-parts":[[2020,7,1]],"date-time":"2020-07-01T07:12:31Z","timestamp":1593587551000},"source":"Crossref","is-referenced-by-count":8,"title":["Radiofrequency catheter ablation without radiation exposure in a 13th week pregnant woman with Wolff-Parkinson-White syndrome"],"prefix":"10.31083","volume":"21","author":[{"given":"Hyung Ki","family":"Jeong","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Medicine, Heart Center of Chonnam National University Hospital, Chonnam National University Medical School, Chonnam National University, 42 Jaebongro, Dong-gu, Gwangju 61469, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Namsik","family":"Yoon","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Medicine, Heart Center of Chonnam National University Hospital, Chonnam National University Medical School, Chonnam National University, 42 Jaebongro, Dong-gu, Gwangju 61469, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyung Wook","family":"Park","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Medicine, Heart Center of Chonnam National University Hospital, Chonnam National University Medical School, Chonnam National University, 42 Jaebongro, Dong-gu, Gwangju 61469, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeong Gwan","family":"Cho","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Medicine, Heart Center of Chonnam National University Hospital, Chonnam National University Medical School, Chonnam National University, 42 Jaebongro, Dong-gu, Gwangju 61469, South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2020,6,30]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","unstructured":"Bigelow, A.
