Bradycardia-dependent complete AV block after TAVR

The patient was a 79-year-old man with a history of coronary artery disease and right coronary artery percutaneous intervention in the remote past. The patient was diagnosed with severe aortic stenosis for which he underwent a transcatheter aortic valve replacement (TAVR) procedure. This was complicated by the development of right bundle branch block (RBBB) postoperatively. Three leads of the electrocardiogram before and after TAVR are shown in Figure 1.
