Optical coherence tomography in ablation-related coronary artery injury
A 43-year-old male with recurrent atrioventricular re-entrant tachycardia refractory to adenosine, amiodarone, and intravenous flecainide underwent a right femoral access radiofrequency ablation (RFA) using four sheaths (6F, 7F, 2 × 8F). The procedure was performed using TactiCath™ D–F irrigated contact force ablation catheter and EnSite Precision™ 3D mapping system (Abbott Laboratories, Chicago, IL, USA). Earliest atrial activation was found at the middle coronary sinus (CS) electrodes. Following trans-septal puncture to access the left atrium, 30–35 W RFA was delivered at 6 o’clock over the mitral annulus. On the right, earliest atrial activity was mapped to the posteroseptal region ...
