Aims: Sutureless aortic valve replacement (SU-AVR) and transcatheter aortic valve implantation (TAVI) are both viable therapeutic interventions for aortic stenosis in elderly patients. Meta-analyses show similar all-cause mortality for both techniques albeit with a different pattern of adverse effects. This study means to compare costs and, to a lesser extent, clinical outcomes of both techniques.

Objectives: We present the long-term results of a trileaflet (Triflo) versus bileaflet (On-X) mechanical valve in both aortic and pulmonary positions in a sheep model.
Methods: The Triflo valve was implanted in 21 female sheep in aortic (n = 8) and pulmonary position (n = 13). The On-X valve was implanted in 7 female sheep in aortic (n = 1) and pulmonary (n = 6) positions.

Objectives: Differences in indication and technique make a randomised comparison between valve-sparing root replacement (VSRR) and personalised external aortic root support (PEARS) challenging. We performed a propensity score (PS)-matched comparison of PEARS and VSRR for syndromic root aneurysm.
Methods: Patients in the PEARS 200 Database and Aortic Valve Insufficiency and ascending aorta Aneurysm InternATiOnal Registry (undergoing VSRR) with connective tissue disease operated electively for root aneurysm <60 mm with aortic regurgitation (AR) <1/4 were included.
Objective: The aim of this study was to evaluate the outcome and experience of the Perceval sutureless valve at our institution (UZ Leuven).
Methods: Between 2007 and 2019, 784 patients underwent sutureless aortic valve replacement using the Perceval valve (isolated or combined with other procedures). We performed a retrospective analysis of the postoperative and follow-up data.
