Ultrafine Structure of Human Aortic Valve Calcific Deposits
نویسندگان
چکیده
Conclusions: Crystals forming mineral blocks of mostly compact matter are nucleated on organic substrates, with their growth controlled by the diffusion of building units through the virtually stagnant layer of interstitial fluid wetting the deposit surface. Preferentially formed precursors of hydroxyapatite, dicalcium, octacalcium and/or amorphous calcium phosphate, are in later stages of deposit development transformed into biological hydroxyapatite.

Calcific pulmonic stenosis.
C ALCIFIC STENOSIS of the aortic valve is a well-recognized and relatively common clinical and pathological entity. In contrast, calcific pulmonic stenosis is rarely encountered either at operation or necropsy. We have observed small deposits of calcium in one or more pulmonic valve cusps in patients who lived into adulthood with left-toright intracardiac shunts, and in older persons with sever...
متن کاملStudy on the structure and composition of aortic valve calcific deposits. etiological aspects
The structures and chemical compositions of valve calcific deposits were investigated. The deposits was chosen arbitrarily and subjected to chemical analysis, observation with scanning microscope, semi-quantitative determination of Ca, Mg, Na, K, P and C elements by energy dispersive X-ray, X-ray diffraction and Fourier transform infra-red spectroscopy carried out. These deposits were found to ...
متن کاملUltrasonic decalcification of calcified cardiac valves and annuli.
Heavily calcified annuli increase the incidence of complications after prosthetic valve replacement-heart block, separation of the aorta or the atrium from the ventricle, late aneurysm formation, paravalvular leak, and haemolysis. An ultrasonic calculus-disintegrator has been developed to remove calcific deposits. The instrument is portable, robust, easily sterilized, inexpensive, and provides ...

Calcific aortic valve disease (CAVD) is a cardiovascular condition that causes the progressive narrowing of the aortic valve (AV) opening, due to the growth of bone-like deposits all over the aortic root (AR). Transcatheter aortic valve replacement (TAVR), a minimally invasive procedure, has recently become the only lifesaving solution for patients that cannot tolerate the standard surgical val...
متن کاملEvidence for heritability of abdominal aortic calcific deposits in the Framingham Heart Study.
BACKGROUND Atherosclerosis is a systemic disease that underlies clinical cardiovascular disease. The radiographic finding of abdominal aortic calcific deposits is an indicator of the presence of aortic atherosclerosis and an independent predictor of cardiovascular disease events. Little is known about the heritability of aortic calcification. METHODS AND RESULTS Original Framingham Heart Stud...
