A 69-year-old man with severe aortic stenosis underwent
transcatheter aortic valve replacement with a 29-mm Edwards Sapien 3 Transcatheter Heart Valve
(Edwards Lifesciences LLC). During the procedure, he had transient 3rd-degree
atrioventricular block, followed by sinus rhythm with PR prolongation, right
bundle branch block, and left anterior fascicular block. Our electrophysiology team
was consulted.
We decided to implant a dual chamber pacemaker (Medtronic)
in DDDR mode. The day after implantation, the following surface
electrocardiogram (ECG) was obtained (programmed atrioventricular [AV] delay,
160 ms).
