Zusammenfassung: | Early and Persistent Intraventricular Conduction Abnormalities and Requirements for Pacemaking After Percutaneous Replacement of the Aortic Valve Nicolo Piazza, Yoshinobu Onuma, Emile Jesserun, Peter Paul Kint, Anne-Marie Maugenest, Robert H. Anderson, Peter P. Th de Jaegere, Patrick W. Serruys We examined the standard 12-lead electrocardiograms of 40 consecutive patients who underwent implantation with the CoreValve Revalving System (CoreValve, Paris, France) for the occurrence of early post-procedural conduction abnormalities and the need for a temporary or permanent pacing. There was a significant increase in the frequency of left bundle branch block (LBBB) after percutaneous implantation of the aortic valve (15% before treatment vs. 55% after treatment, p = 0.001). Although the incidence of LBBB had decreased after follow-up of 1 month, it did not reach statistical significance, with the proportion decreasing from 55% to 48% (p = 0.63). A temporary and permanent pacemaker was required in 20% and 18% of patients, respectively. |
