1 Usefulness of a 2-F catheter electrode in a case with successful electrical isolation of remarkably hypoplastic right inferior pulmonary vein  Takeshi Kitamura, MD, Seiji Fukamizu, MD, Rintaro Hojo, MD, Harumizu Sakurada, MD, PhD, Masayasu Hiraoka, MD, PhD, FHRS  HeartRhythm Case Reports  Volume 1, Issue 3, Pages (May 2015) DOI: /j.hrcr Copyright © 2015 Heart Rhythm Society Terms and Conditions

2 Figure 1 A: Three-dimensional enhanced computed tomography scanning of the left atrium. Note the remarkably hypoplastic RIPV. B: Three-dimensional electroanatomic mapping of catheter positions of the successful ablation site for the RIPV. LA = left atrium; RIPV = right inferior pulmonary vein; RtPA = right pulmonary artery.

3 Figure 2 Fluoroscopic AP projection view of ablation arrays at ablation sites shown in Figure 1B. AP = anteroposterior; RIPV = right inferior pulmonary vein. HeartRhythm Case Reports 2015 1, DOI: ( /j.hrcr ) Copyright © 2015 Heart Rhythm Society Terms and Conditions

4 Figure 3 A: Intracardiac electrograms at the initiation of atrial fibrillation from the remarkably hypoplastic RIPV firing. The arrows indicate firing from the RIPV. B: Intracardiac electrograms during radiofrequency application to electrically isolate the RIPV. The arrows indicate RIPV potentials. ABL = ablation; CS = coronary sinus; d = distal; p = proximal; RA = right atrium; RIPV = right inferior pulmonary vein; RSPV = right superior pulmonary vein.
