Femoral or Radial Secondary Access in TAVR: A Subanalysis From the Multicenter PULSE Registry.

Background: Transradial secondary access (TR-SA) may serve as an alternative to the traditional femoral secondary access (TF-SA) for pigtail placement in transcatheter aortic valve replacement (TAVR).

Objectives: The aim of this study was to assess the incidence of secondary access-related vascular complications after TR-SA or TF-SA in TAVR.

Methods: The PULSE (Plug or sUture based vascuLar cloSurE after TAVR) registry retrospectively evaluated data of 10,120 patients who underwent transfemoral TAVR at 10 heart centers from 2016 to 2021.

Computed Tomography-Based Assessment of Transvalvular Pressure Gradient in Aortic Stenosis.

In patients with aortic stenosis, computed tomography (CT) provides important information about cardiovascular anatomy for treatment planning but is limited in determining relevant hemodynamic parameters such as the transvalvular pressure gradient (TPG). In the present study, we aimed to validate a reduced-order model method for assessing TPG in aortic stenosis using CT data. TPG was calculated using a reduced-order model requiring the patient-specific peak-systolic aortic flow rate (Q) and the aortic valve area (AVA).
