2025年1月8日 · The more common form of bicuspid aortic valve occurs in a valve with three cusps with underdevelopment of a commissure and fusion of two adjacent cusps to form a raphe 7. Over time, the abnormal stress across the valve leads to calcification, usually in adulthood.

2017年3月1日 · Bicuspid aortic valves with raphe had a significantly higher prevalence of valve dysfunction, with a significantly higher frequency of aortic regurgitation (622 [33.1%] vs 57 [24.1%], P < .001) and aortic stenosis (728 [38.7%] vs 51 [21.5%], P < .001).

2019年12月6日 · A raphe between two fused cusps is visible in 50–88% in bicuspid aortic valve (BAV) by transthoracic echocardiogram (TTE) and the presence of raphe, particularly if calcified, is associated with early BAV degeneration and future development of aortic stenosis (AS).

The aortic valve was evaluated in a cross-sectional view for the presence and extent of a raphe. For valves where a raphe could be distinguished (subgroup A), distinction was made between a complete raphe and an incomplete raphe.

Anatomical and clinical predictors of valve dysfunction and aortic dilation in bicuspid aortic valve disease.

Aortic aneurysms are defined as those with dimensions greater than 50 mm. The association between the presence of a raphe, and the risk of aortic valve dysfunction and aortopathy was also analyzed.

2017年9月6日 · Classification of bicuspid aortic valve based on computed tomography in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). A, A tricommissural, functionally bicuspid aortic valve. A bicommissural raphe-type bicuspid aortic valve is presented in B. The arrow indicates the calcified raphe between the ...

Bicuspid aortic valve is categorized as no raphe type (C and D) and raphe type (E to H). Raphe type is further categorized as noncalcified raphe type (E and F) and calcified raphe type (G and H) . Arrowheads indicate noncalcified raphe, and arrows indicate calcified raphe.

Aim: To determine whether the presence and extent of the raphe (fusion site of valve leaflets) is associated with the degree of aortopathy and valvular dysfunction in patients with isolated BAV and associated aortic coarctation (CoA).

In one common lesion, 2 cusps are fused together. The conjoined area of the fused cusps is termed raphe. Occurring in 1% to 2% of the population, the bicuspid aortic valve (BAV) is the most common congenital cardiac malformation. The majority of …
