Complete heart block and subsequent sudden cardiac death following transcatheter tricuspid valve replacement in a heart transplant patient: a case report

This is the first case report of a complication of transcatheter tricuspid valve replacement in a heart transplant patient resulting in complete heart block and sudden cardiac death. While TTVR may be a good treatment option for select patients in this high-risk group, conduction system damage is a potential complication given the anatomy of the region and requires very close monitoring. This case further highlights the unique physiology of HT patients and illustrates the fact that bradyarrhythmias are often poorly tolerated and potentially lethal.
