Old calcified aortic stenosis and aortic valve calcification simple ultrasound diagnosis
, Moving map on the old valve degeneration diagnosis ¨ J with Doppler technology in particular, found that older calcified aortic stenosis increased, the elderly about 3% to 4% of its cause is aortic valve ring and aortic valve leaves replaced senescent progressive degeneration of collagen fibers, calcium and fat accumulation of calm,[link widoczny dla zalogowanych], valvular thickening caused by deformation at the adhesive joint integration week to be in a narrow valvular position can be expressed on a clinical C ',[link widoczny dla zalogowanych], colic, faint of heart failure and even sudden death; cardiac auscultation can be heard and the typical multi-jet samples of hair rough systolic murmur. Simple aortic valve calcification in elderly mainly fibrosis and calcification of the aortic valve, very few violations of the free edge,[link widoczny dla zalogowanych], the joint at the adhesive does not occur,[link widoczny dla zalogowanych], although stiff valve leaflets, but the valve is only slightly limited or fixed tim normal, and therefore no obvious clinical symptoms. 3.2 are both similarities and differences between ultrasonic seal degenerative aortic valve disease,[link widoczny dla zalogowanych], so the two-dimensional echocardiography images share many manifestations: aortic valve thickening and nodular deformation of calcified plaque echogenic leaflets stiff open to varying degrees by the storm, there are different degrees of aortic diameter widened. But the old calcified aortic valve stenosis combined valve pathology shame there are still Fusion induced adhesion of aortic valve stenosis and close all caused significant hemodynamic abnormalities Lang, which has its characteristic ultrasound: left ventricular hypertrophy, aortic valve combined To finance units at the adhesion valve Yan mobility decreased more in the moderate or moderate stenosis above. Valve opening rate 15mm, and therefore no significant hemodynamic changes, left ventricular and active {House of smell no significant pressure difference is worth noting that , old calcified aortic stenosis in early aortic valve calcification in elderly with simple changes in the ultrasound image may be completely unable to identify shed, but over time the dynamic tracking. His aortic valve calcium old prison will gradually narrow the ultrasonic characteristics displayed. If the two-dimensional ultrasound, M-mode ultrasound, multi-Xi Le ultrasound examination. Clinical data, may make the correct diagnosis and identification of calcified aortic stenosis aged and elderly need well calcified rheumatic aortic stenosis identification, the latter often: ① a history of rheumatic heart disease for several decades and / or heart failure history: ② disease often involving the aortic valve 3 valve; ③ often accompanied by mitral stenosis j} Xinjiang and / or mitral: All therefore make the correct diagnosis can
