THE human aortic valve consists of three cusps made of relatively inelastic, muscle-free material about 0.15 mm thick. It opens and shuts about once a second, and withstands a pressure difference ...

Transthoracic and transesophageal echocardiography revealed a mobile mass on the right coronary cusp of the aortic valve. Multislice CT demonstrated a significant narrowing in the proximal left ...

There was free aortic regurgitation because of dilatation of the valvular annulus; the cusps themselves were not deformed. The valve was excised and a No. 9 Starr-Edwards valve inserted.

PVL observed after transcatheter aortic valve implantation (TAVI), (D, E) CT imaging after the initial TAVI, (F) redo TAVI, (G) CT imaging after redo TAVI, (H) PVL observed after redo TAVI. R: ...

Or it may happen later (acquired). It occurs more often in boys than in girls. A normal aortic valve has 3 cusps (leaflets) that act as a one-way door. With aortic stenosis, the valve doesn’t work as ...

in regions of the aortic valve prone to degenerative changes, particularly calcification, at the base and proximal areas of the cusps. This suggests that CD34+ VICs play a critical role in maintaining ...

Large and rare duplications and deletions in a chromosome region known as 22q11.2 , which involves genes that regulate ...

THE SOLVE-TAVI trial demonstrated that both valve type and anaesthesia strategy yielded comparable long-term outcomes in ...

Aortic valve calcification (AVC) has been shown to be a powerful assessment of aortic stenosis (AS) severity and a predictor of adverse outcomes. However, its accuracy in patients with low-flow AS has ...

Billy Wagner has a great shot to make it in his last year on the ballot. Carlos Beltrán is on the cusp and may just clear the 75% hurdle. The last question is CC Sabathia. By customary measures ...
