Alteraciones de la conducción auriculoventricular y predictores de la necesidad de marcapasos tras el implante percutáneo de la prótesis aórtica de CoreValve®

Factors Predicting and Having an Impact on the Need for a Permanent Pacemaker After CoreValve Prosthesis Implantation Using the New Accutrak Delivery Catheter System

“…Our study also confirms other previously described factors regarding the need for pacemaker implantation: the depth of the prosthesis in the LVOT (14,15) and the previous presence of RBBB (14,21). The improvements incorporated into the release system of the prosthesis thus allow greater stability during the implantation and a higher position, resulting in a reduction in AV conduction disorders.…”

“…The incidence of AV conduction disturbances with the need to implant a definitive pacemaker after TAVI with the CoreValve aortic valve prosthesis is high (15,16). This is easily explained if we recall the anatomic relation between the AV conduction system and the aortic valve.…”

Bundle-branch reentry ventricular tachycardia after transcatheter aortic valve replacement

“…Only 5–10% of the patients develop a right-bundle branch block, as seen in our patient. Lastly, approximately 25–30% of the patients with a Core valve prosthesis need a pacemaker implantation [1] .…”
