What causes this aortic sentry to go awry? Calcium, for one. As we get older, it accumulates on the aortic valve, and this is a primary cause of stenosis [source: Nishimura]. These deposits stiffen the leaflets, thicken the annulus and commonly appear around age 60, but they don't...

In the current issue of Circulation, Ix et al demonstrate an inverse correlation between mitral and aortic valve calcification and serum fetuin-A levels in a cross-sectional study of 970 patients with coronary artery disease and without renal disease.1 Increased serum fetuin was significantly associat...
Manual versus automatic detection of aortic annulus plane in a computed tomography scan for transcatheter aortic valve implantation screening. Precise measurements of aortic annulus dimensions are crucial for prosthesis size selection in patients undergoing transcatheter aortic valve implantation ... Arnaud,V...
MIP (c) and VR (d) views show the overall extent of MAC reaching the mitral-aortic curtain and the aortic valve. Another cause of MAC is caseous calcification of the mitral annulus (CCMA), a benign entity that can mimic a granuloma, abscess or cardiac mass. CCMA typically involves the...
A particularly illustrative example of this is observed in the increased CIED implantation rates associated with transcatheter aortic valve implantation (TAVI). Damage to the conduction system during TAVI procedures results in the need for PPM implantation in about 10–14% of cases (compared to under...
It signifies that part of the cardiac cycle between aortic valve closure and MVO, where the ventricle relaxes (diastole) without lengthening, and ventricular volume is unaltered. Wiggers described it in 1923 [59,60], as does today's Stedman Medical Dictionary [60]. The ventricle is isovol...
