Abstract
Aims. Permanent pacemaker requirement is a known complication after transcatheter aortic valve implantation (TAVI). The aim of the present study was to analyze the effects of Edwards SAPIEN prosthesis implantation on atrioventricular conduction. Methods. The study included 28 patients who underwent TAVI due to severe aortic valve stenosis. An electrophysiological study was performed in the catheterization room immediately before the initial balloon valvuloplasty and immediately after Edwards SAPIEN prosthesis implantation. Results. His-ventricle interval was significantly prolonged postprocedure (55.9 +/- 11.5 ms) vs preprocedure (47.3 +/- 7.8 ms) (P<.001). The antegrade Wenckebach point was observed to be significantly prolonged postprocedure (354.4 +/- 41.3 ms) vs preprocedure (333.7 +/- 45.4 ms) (P=.001). Despite atrial-His interval prolongation, it was not statistically significant. After the procedure, we observed significant conduction disturbances in 3 patients (10.7%). These conduction problems recovered before discharge. One of the patients (3.6%) with right bundle branch block + left anterior fascicular block required permanent pacemaker implantation. At postprocedure electrocardiogram, QRS duration increased, QRS axis shifted to the left, and both of the values became normal before discharge. The patient-s echocardiographic and clinical parameters were improved during follow-up. Conclusion. The effect of Edwards SAPIEN on the conduction system was mostly infranodal and temporary. The physical properties of the Edwards SAPIEN prosthesis may explain this observation. This complication may be lessened if the frame height characteristics can be improved.
