Predictors of permanent pacemaker implantation in aortic valve diseases after TAVI with vitaFlow liberty system

Abstract

IntroductionPermanent pacemaker implantation (PPI) is a known complication in patients with aortic stenosis following transcatheter aortic valve implantation (TAVI). However, there is limited research on TAVI for pure aortic regurgitation (PAR), and more investigation is needed to determine the occurrence of postoperative cardiac conduction block and the need for PPI in this population. Therefore, this retrospective analysis aimed to evaluate the incidence of cardiac conduction block and the necessity of PPI after TAVI in patients with different types of aortic valve disease, including pure aortic stenosis (PAS), aortic stenosis with regurgitation (ASR), and PAR.MethodsClinical data of 100 patients who TAVI were analyzed retrospectively. The incidence of conduction block was assessed, and clinical factors were examined to predict the necessity of PPI.ResultsCardiac conduction block was found to be a common complication following TAVI, particularly in patients with PAR. PAR was identified as an independent risk factor for requiring PPI. Additionally, first-degree atrioventricular block emerged as a sensitive predictor for PPI in patients with PAR.DiscussionThese findings provide valuable insights into the safety and effectiveness of TAVI, which can help enhance patient management and reduce complications.

Predictors for new-onset conduction block in patients with pure native aortic regurgitation after transcatheter aortic valve replacement with a new-generation self-expanding valve (VitaFlow Liberty™): a retrospective cohort study

“…In comparison to other self-expanding transcatheter heart valves, the first-generation VitaFlow™ valve is associated with a lower degree of AR, and fewer patients with AS undergoing TAVR with these valves develop moderate-to-severe AR [ 29 ]. Data from our hospital showed a lower new PPI rate (3.03%) after TAVR with the new-generation VitaFlow ™ valve (VitaFlow Liberty™) in patients with AS [ 25 ].…”

“…Data from our hospital revealed that patients with PNAR were more prone to developing new conduction blocks requiring PPI compared to patients with AS [ 25 ]. Evidently, there is an urgent need for further research to investigate the causes of these complications and to optimize the management and treatment of patients requiring PPI after TAVR.…”
