: A 56-year-old patient was referred because of refractory heart failure and mild haemolysis caused by multiple, severe paravalvular leaks of a Starr-Edwards valve implanted in mitral position 23 years before. Owing to perceived high risk of surgical re-valving, percutaneous paravalvular leak occlusion was performed by implantation of multiple, simultaneously deployed Amplatzer Vascular Plugs.

Background: There are several high-risk treatment options for valve failure of a biological full root replacement. When tailoring the best treatment option for the patient, implantation of a rapid deployment valve (RDV) should be considered.
Case Presentation: Six patients presented with aortic regurgitation in a full root Freestyle bioprosthesis.

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.

Background: The Hydra CE study revealed 1-year favorable efficacy of TAVR, showing a large effective orifice area (EOA), low gradient, and acceptable complication rates.
Aims: We evaluated the 3-year clinical and hemodynamic outcomes of Hydra self-expanding transcatheter aortic valve (manufactured by Vascular Innovations Co Ltd, Nonthaburi, Thailand; a subsidiary of Sahajanand Medical Technologies Limited, India) in patients with symptomatic severe aortic stenosis at high or extremely high surgical risk.
Methods: The Hydra CE study was a prospective, multicenter, single-arm study.

Background And Objective: Prosthetic heart valve interventions such as TAVR have surged over the past decade, but the associated complication of long-term, life-threatening thrombotic events continues to undermine patient outcomes. Thus, improving thrombogenic risk analysis of TAVR devices is crucial. In vitro studies for thrombogenicity are typically difficult to perform.
