Background: Vascular complications remain prevalent on transfemoral transcatheter aortic valve replacement (TF-TAVR) with a significant proportion related to the secondary arterial access. We hypothesized that placing the second sheath ipsilateral and distal to the delivery sheath could reduce vascular complications with similar safety and efficacy.
Objectives: Comparing vascular complications and clinical outcomes when placing the secondary arterial sheath in the ipsilateral (unilateral-access) versus in the contralateral (bilateral-access) femoral artery during TF-TAVR.
Purpose: Left ventricular myocardial work (LVMW) has been shown to better characterize LV function in patients with severe aortic stenosis by correcting LV afterload. The aim of this study was to evaluate the evolution in LVMW indices after transcatheter aortic valve replacement (TAVR) and their prognostic value.
Methods: The following LVMW indices were calculated before and immediately after TAVR in 255 patients (median age 82 years, 51% male): global work index (GWI), global constructive work (GCW), global wasted work (GWW) and global work efficiency (GWE).
Background: The PRAETORIAN score was developed as an alternative for defibrillation testing after subcutaneous implantable cardioverter-defibrillator implantation to assess 3 aspects of implant position on a bidirectional chest radiograph. The score is validated on a standard standing chest radiograph with arms elevated in the lateral view.
Objective: We aimed to evaluate the effect of different anatomic positions on the PRAETORIAN score.
