Purpose: Development of AV-block is a frequent complication associated with transcatheter aortic valve implantation (TAVI). To date little is known about the predictive value of the HV-interval prior to TAVI with respect to the risk of AV-block development.
Methods And Results: HV-interval was determined in 25 consecutive elderly patients with severe aortic valve stenosis (AS) before and immediately after TAVI.
