Background: The influence of permanent pacemaker implantation upon outcomes after transcatheter aortic valve implantation (TAVI) remains controversial.
Aims: To evaluate the impact of permanent pacemaker implantation after TAVI on short- and long-term mortality, and on the risk of hospitalization for heart failure.
Methods: Data from the large FRANCE-TAVI registry, linked to the French national health single-payer claims database, were analysed to compare 30-day and long-term mortality rates and hospitalization for heart failure rates among patients with versus without permanent pacemaker implantation after TAVI.
Objectives: The estimation of systolic pulmonary artery pressure (sPAP) by transthoracic echocardiography (TTE) is challenging in patients with severe tricuspid regurgitation (TR). The study aimed to determine the reliability of the assessment of sPAP by TTE in this population.
Methods: This study was a single-centre analysis of consecutive patients at the University Hospital of Rennes with right heart catheterisation and TTE, performed with a maximum delay of 48 hours.
New-onset conduction disturbances, including left bundle branch block and permanent pacemaker implantation, remain a major issue after transcatheter aortic valve implantation. Preprocedural risk assessment in current practice is most often limited to evaluation of the baseline electrocardiogram, whereas it may benefit from a multimodal approach, including ambulatory electrocardiogram monitoring and multidetector computed tomography. Physicians may encounter equivocal situations during the hospital phase, and the management of follow-up is not fully defined, despite the publication of several expert consensuses and the inclusion of recommendations regarding the role of electrophysiology studies and postprocedural monitoring in recent guidelines.

- Guidelines suggest aortic valve replacement for severe aortic stenosis when patients exhibit symptoms or reduced left ventricular ejection fraction, which indicates advanced disease severity.
- This study aimed to analyze changes in myocardial work for patients undergoing transcatheter aortic valve implantation (TAVI) by evaluating echocardiographic data before and after the procedure.
- The results showed a significant decrease in mean transaortic pressure gradient and improvements in myocardial work indices post-TAVI, indicating that these measures could help better understand the left ventricular effects of aortic stenosis and treatment outcomes.
Background: Conduction disturbances requiring permanent pacemaker implantation (PPI) remain a common complication of transcatheter aortic valve replacement (TAVR).
Objective: The purpose of this study was to determine the prognostic impact of PPI after TAVR according to the timing of implantation relative to TAVR.
Methods: A total of 1199 patients (median age 83 years; interquartile range 78-86 years; 549 [45.
