Transcatheter aortic valve implantation (TAVI) is now utilised as a less invasive alternative to surgical replacement (SAVR) across the whole spectrum of risk. Long-term durability bioprosthetic valves has become key goal TAVI this procedure considered for younger and lower-risk populations. The purpose article present state-of-the-art overview on definition, aetiology, risk factors, mechanisms, diagnosis, clinical impact, management dysfunction (BVD) failure (BVF) following with comparative perspective versus SAVR. Structural deterioration (SVD) main factor limiting used or SAVR, but non-structural BVD, such prosthesis-patient mismatch paravalvular regurgitation, well thrombosis endocarditis may also lead BVF. incidence BVF related SVD other causes low (<5%) at midterm (5- 8-year) follow-up compares favourably that long-term data randomised trials conducted first generations transcatheter heart suggest similar in SAVR 10 years, these suffer from major survivorship bias, will need be confirmed by analysis low-risk years.

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.

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.

With the rise of transcatheter aortic valve-in-valve (ViV) procedures for high-risk patients with degenerated surgical valves, precise positioning heart valve (THV) within (SHV) is crucial optimal functional outcomes. This study aims to explore impact implantation depth on outcomes post-ViV in a controlled vitro setting. focused fluid dynamics characteristics and subsequent ViV procedural Rigorous experiments measured structural parameters based these, appropriate Taurus Elite valves were selected pulse flow testing under simulated conditions varying rates cardiac outputs. Fluid dynamic evaluations conducted THVs sizes 21, 23, 26, 29 mm SHVs from two brands: Hancock II (Medtronic, USA) BalMedic (Balance Medical, China) across range diameters. In-depth analysis was performed at output (CO) 5 L/min rate (HR) 70 bpm, focusing key metrics such as transvalvular pressure gradient (TVPG), effective orifice area (EOA), total regurgitation fraction (TRF) depths -2.5, 0, 2.5, gain insights into interaction between THV placement hemodynamic performance. Anchoring force tests also SHV-THV combinations -2.5 0 ensure safety implantation. Significant differences observed TVPG, EOA, TRF various SHV brands sizes, emphasizing importance positioning. Specifically, Elite23 demonstrated superior TVPG performance compared Elite21, indicating better match BalMedic19 II21, especially ranging mm. Elite29 showed lowest all tested depths, making it preferred choice BalMedic25 II27. These findings highlight selecting model determining different SHVs. In both interventional can affect its opening-closing morphology. The recommended shallowly possible this has guiding significance clinical surgeries.
