Bioprosthetic Aortic Valve Thrombosis: Definitions, Clinical Impact, and Management: A State-of-the-Art Review

Circulation Cardiovascular Interventions, Journal Year: 2024, Volume and Issue: 17(7)

Published: June 10, 2024

Bioprosthetic aortic valve thrombosis is frequently detected after transcatheter and surgical replacement due to advances in cardiac computed tomography angiography technology standardized surveillance protocols low-surgical-risk trials. However, evidence limited concerning whether subclinical leaflet leads clinical adverse events or premature structural deterioration. Furthermore, there may be net harm the form of bleeding from aggressive antithrombotic treatment patients with thrombosis. This review will discuss incidence, mechanisms, diagnosis, optimal management bioprosthetic replacement.

Published: Jan. 14, 2025

With the aging of general population and rise in surgical transcatheter aortic valve replacement, there will be an increase prevalence prosthetic valves. Patients with valves can develop a wide range unique pathologies compared to population. Accurate diagnosis is necessary this generate comprehensive treatment plan. Transthoracic echocardiography often insufficient alone diagnose many pathologies. The integration imaging modalities, including transthoracic echocardiography, transesophageal cardiac computed tomography, magnetic resonance imaging, nuclear care for patients purpose review describe strengths, limitations, contemporary use different modalities dysfunction.

Image‐Based Analysis of Correlation Between Valve Stent Deformation and Valve Function in Transcatheter Aortic Valve Replacement

Catheterization and Cardiovascular Interventions, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 26, 2025

Currently, there remains a paucity of research on the deformation and valve function transcatheter heart valves (THV) in patients with aortic regurgitation (AR) following replacement (TAVR). This study aimed to thoroughly explore correlation between THV postoperative hemodynamics these patients. In this study, we assessed 39 AR treated J-Valve system during TAVR. We utilized cardiac-enhanced computed tomography angiography (CTA) examine extent stent deformation, correlating measurements concurrent echocardiographic data. Among AR, exhibited three distinct configurations: rectangular, trapezoidal, inverted trapezoidal shapes. The rectangular configuration showed trend toward larger effective orifice area (EOA) compared configurations (rectangular: 2.20 ± 0.11 cm², trapezoidal: 1.88 0.08 2.04 cm²; p = 0.068). Stratified analysis degree inclined commissural posts indicated that THVs all angles < 5° highest standard EOA (sEOA). An increase number correlated decrease sEOA. Furthermore, higher was observed when expansion mid transition level exceeded 80%. During TAVR procedure, ensuring sufficient stent, maintaining configuration, avoiding tilting contribute achieving favorable hemodynamics.
