Frequency of conduction disturbances after transcatheter implantation of an Edwards Sapien aortic valve prosthesis.
American Journal of Cardiology 2010 September 2
We evaluated the incidence of conduction abnormalities and requirement for permanent pacemaker in patients undergoing transcatheter aortic valve implantation (TAVI) with the Edwards Sapien prosthesis. In 2009, >8,000 patients were treated with TAVI using 1 of the 2 commercialized models of bioprosthesis (Edwards Sapien, Edwards Lifesciences, Irvine, California; and CoreValve, Medtronic, Irvine, California). Occurrence of conduction abnormalities including complete atrioventricular block requiring permanent pacemaker has been reported after TAVI with the 2 models of valve, more frequently with the CoreValve. We analyzed standard 12-lead electrocardiograms of 69 consecutive patients in whom an Edwards Sapien prosthesis was successfully implanted. Electrocardiograms were examined before treatment, at day 1, and at 1-month follow-up. Heart rate, PR and QT intervals and QRS duration were measured and the presence of a first-, second-, or third-degree atrioventricular block was documented. There was a slight increase in heart rate and a discrete decrease in QT interval at day 1. These values had returned to baseline values at 1 month. There was no change in PR interval but a transitory increase in QRS duration was noted. Frequency of left bundle branch block increased from 14.5% at baseline to 27.5% at day 1 with a decreased incidence at day 30 (21.3%). Permanent pacemaker was required in only 3 patients (4.3%). In conclusion, in our experience, conductive disorders and requirement of a definitive pacemaker after implantation of an Edwards Sapien aortic bioprosthesis are infrequent. The physical properties of this prosthesis may explain this observation.
