1 Acute right coronary artery occlusion after radiofrequency catheter ablation of cavotricuspid isthmus: Vascular response assessed by optical frequency domain imaging  Naohiro Funayama, MD, Takao Konishi, MD, Tadashi Yamamoto, MD, PhD, Seiichiro Sakurai, MD  HeartRhythm Case Reports  Volume 3, Issue 10, Pages (October 2017) DOI: /j.hrcr Copyright © 2017 Heart Rhythm Society Terms and Conditions

2 Figure 1 Coronary angiography (A, B, C) and optical frequency domain imaging (D, E, F). A: Initial angiography. B: An immediate coronary angiography showed an occlusion (white arrow) of the posterolateral branch. C: Final angiography. D: Proximal site maintained a normal “three-layer” structure. E: Optical frequency domain imaging revealed thickening of the intima and thrombus at the target lesion. F: Distal site had fibrous and fibrocalcific plaques.

3 Figure 2 A: Computed tomography (CT) image. PDA = posterior descending artery; PLA = posterolateral artery; RA = right atrium; RV = right ventricle. B: Enlarged view. C: Corresponding view of 3-dimensional electroanatomic mapping system and CT. The dots present the radiofrequency applications. Right anterior oblique (RAO) view and left anterior oblique (LAO) view. RCA = right coronary artery. HeartRhythm Case Reports 2017 3, DOI: ( /j.hrcr ) Copyright © 2017 Heart Rhythm Society Terms and Conditions
