Conduction disorders after transcatheter aortic valve implantation: a focused review.

Transcatheter aortic valve implantation (TAVI) is a less invasive approach to aortic valve replacement than traditional open chest surgery. It has been very successful in elderly and sick patients who might have otherwise been turned down for surgery. However, many patients who have the procedure develop conduction disease, including new LBBB or complete heart block, and may need permanent pacing or ongoing follow-up to monitor for worsening conduction problems. Here we discuss the risk for conduction disease with TAVI, identifying which patients may need a pacemaker or long-term rhythm follow-up, and methods to decrease the risk of worsening conduction.
