We observed a higher incidence of early conduction disorders and need for PPM implantation after PAVR than generally reported after surgery. Whether this observation is clinically important requires larger prospective studies and follow up.

LBBB and PPM implantation requirement after TAVI are common occurrences using the self-expanding CoreValve prosthesis. In this large series of consecutive patients, only RBBB was found to be a strong predictor of PPM requirement.

This study indicates that VAs are common in patients with AS. We observed a significant decrease in the incidence and severity of PVCs since the first month after TAVI. Furthermore, after 1 year follow-up there was a further and significant reduction in the frequency of complex PVCs. This may be related to the benefits determined by valve replacement on left ventricular function.
