2025年2月1日 · The main findings of our study are that patients receiving mechanical aortic prostheses demonstrated superior long-term survival. This benefit is especially apparent in smaller valve sizes with a 19-mm mechanical valve providing better long-term survival than both 19- and 21-mm bioprosthetic valves, and equivalent to 23-mm bioprosthetic valves.

2025年1月25日 · The choice of bioprosthetic or mechanical surgical aortic valve replacement (AVR) should balance individual valve durability with the potential liabilities of oral anticoagulation. Objective To inform clinical practice, this study sought to evaluate contemporary, real-world, long-term AVR outcomes from the Society of Thoracic Surgeons Adult ...

2024年9月2日 · Identify candidates most suitable for mechanical aortic valve replacement based on clinical indications and patient characteristics. Differentiate between mechanical and biological valve options, considering patient-specific factors and long-term management needs.

2025年1月25日 · Mechanical surgical aortic valve replacement (AVR) was associated with lower all-cause mortality in patients ≤60 years old compared with bioprosthetic AVR, according to a study on the longitudinal survival difference among more than 100,000 patients presented at the Society of Thoracic Surgeons (STS) Annual Meeting and simultaneously ...

2022年8月18日 · Replacement of the native aortic valve with a mechanical one is associated with the need for lifelong anticoagulation, significantly increasing the patient’s risk of hemorrhage. On the other hand, biological valves are more prone to structural deterioration, requiring reoperation.

2 天之前 · Aortic valve anatomy. In addition to surgical risk, the anatomy of the aortic valve and presence of concomitant disease such as aortic aneurysm, coronary artery disease, atrial fibrillation or other valvular heart disease should be considered to ensure that each patient is treated with a comprehensive approach. Patient longevity.

2024年6月29日 · This review summarizes relevant literature regarding valve choice (bioprosthetic, mechanical, or Ross procedure), interventional strategies (TAVR vs SAVR), and lifetime management to help providers counsel their patients with aortic stenosis in a shared decision-making model to select the right valve for each patient.

2024年12月14日 · We present a case where the use of a sutureless valve implanted within the ring of a mechanical valve helped minimize the aortic cross-clamp time and avoid a potentially complex aortic root reconstruction.

2025年2月14日 · BackgroundValve‐in‐valve transcatheter aortic valve replacement (TAVR) is a recognized alternative for treating the structural valve deterioration of bioprosthetic valves. ... although the 2014 American Heart Association/American College of Cardiology guidelines recommended mechanical valves for patients <60 years of age, 7 the 2020 update ...

2025年2月12日 · Recent randomized clinical trials (RCTs) on the effects of early intervention in patients with asymptomatic severe aortic stenosis (AS) support a reconsideration of current practice patterns. 1-3 The 2020 guidelines on the timing of aortic valve replacement (AVR) include several class 2a recommendations for asymptomatic patients with severe AS (stage C1) in selected situations. 4 These ...
