We present results of the histopathological workup of a prosthetic aortic valve which was explanted from a 31-year-old woman due to valve thrombosis during early pregnancy. Our images demonstrate nicely thrombotic material directly adherent to the pyrolytic carbon surface in a human specimen.

25 years of Ross operation in adults: the inclusion technique keeps up the expectations.
J Thorac Cardiovasc Surg
January 2025
Institute for Health Transformation, Western Health, Melbourne, Australia.
Background: In adults the Ross procedure provides an excellent alternative to prosthetic valves, but it is underutilised because of concerns about technical complexity, durability, and perceived high late reoperation rates. The inclusion technique stabilizes the aortic root, prevents dilatation, and respects the dynamic root physiology. Long-term outcomes of the Ross procedure with the inclusion cylinder technique (1992-2022) are reported.

Background Patients undergoing transcatheter aortic valve implantation (TAVI) are often elderly, and perioperative and long-term risk assessments should primarily consider cognitive function, comorbidities, and procedural complexity. This study investigated the association between cognitive function and mortality in patients with severe aortic valve stenosis (AS) who underwent TAVI. Methodology This single-center, retrospective cohort study consecutively registered patients who underwent TAVI between December 2014 and December 2018.

Cardiovasc Intervent Radiol

Department of Surgery, Rijnstate Hospital, Arnhem, The Netherlands.
Purpose: To investigate the influence of antithrombotic therapy on occurrence of thrombotic and bleeding complications after endovascular aneurysm repair (EVAR).
Methods: In this retrospective single-center cohort study, patients who underwent elective endovascular aneurysm repair for abdominal aortic aneurysm were categorized into three antithrombotic groups: single antiplatelet therapy (SAPT), anticoagulants, or dual antiplatelet therapy (DAPT). Outcome measures were the incidence of major adverse cardiovascular events (MACE), prosthetic limb occlusions, and bleeding complications during follow-up.
Transcatheter closure of paravalvular leakage through multiple approaches after surgical mechanical valve replacements: A retrospective study.
Medicine (Baltimore)
November 2024
Department of Cardiovascular Surgery, Xijing Hospital, Air Force Medical University, Xi'an, Shaanxi Province, China.
Background: Transcatheter closure of percutaneous paravalvular leak (PVL) is a technically challenging procedure, especially after surgical mechanical valve replacements (SMVR), as the risk of interference with the prosthetic valve discs and the complex interventional techniques required for mitral PVL closure. Our study was designed to review the results with transcatheter closure of PVL after SMVR.
Methods: From January 2018 through December 2023, a total of 64 patients with PVL after SMVR underwent transcatheter closure with the help of preoperative 3-dimensional printing model and simulator for image evaluation.
Analysis of the haemodynamic changes caused by surgical and transcatheter aortic valve replacements by means fluid-structure interaction simulations.

Aortic valve replacements, both surgical and transcatheter, are nowadays widely employed treatments. Although clinically effective, these procedures are correlated with potentially severe clinical complications which can be associated with the non-physiological haemodynamics that they establish. In this work, the fluid dynamics changes produced by surgical and transcatheter aortic valve replacements are analysed and compared with an ideal healthy native valve configuration, employing advanced fluid-structure interaction (FSI) simulations.
