Very late occurrence of complete heart block without preexisting atrioventricular conduction abnormalities: A rare complication after transaortic valvular replacement Nagesh Chopra, MD, Matthew S. Tong, DO, Steven J. Yakubov, MD HeartRhythm Case Reports Volume 4, Issue 2, Pages 77-81 (February 2018) DOI: 10.1016/j.hrcr.2017.11.010 Copyright © 2017 Heart Rhythm Society Terms and Conditions

Figure 1 A: Baseline 12-lead electrocardiogram (ECG) of case 1 before transaortic valve replacement, showing normal sinus rhythm with a normal PR interval as well as an rSR pattern in lead V1 with normal QRS axis and duration. B: Twelve-lead ECG of the same patient 20 hours after transaortic valve replacement prosthesis deployment, showing minor changes in the septal depolarization as detailed in the case report. These changes resolved on follow-up ECG in 1 month. HeartRhythm Case Reports 2018 4, 77-81DOI: (10.1016/j.hrcr.2017.11.010) Copyright © 2017 Heart Rhythm Society Terms and Conditions

Figure 2 A: Baseline 12-lead electrocardiogram (ECG) of case 2 before transaortic valve replacement, showing normal sinus rhythm with a normal PR interval as well as QRS axis and intervals. B: Twelve-lead ECG of the same patient on postprocedure day 4, showing no changes in the QRS axis or precordial septal activation. Mild prolongation of the PR interval, although still in the normal range, is noted.
