Which unusual _'s treatments does plump type patient's supersound of myocardium disease aroused in interest have to pursue to check
Pursue to check and diagnose to the plump type myocardium disease that there is important value in the supersound aroused in interest, can judge cardiac muscle plump position and intensity ocularly.The typical plump type myocardium disease patient can have the following supersound to change:
(1)The asymmetry of interventricular septum is plump, activity degree is poor, the heart is diminished, the left room systolic phase internal diameter shrinks, the wall thickness proportion (IVS/ LVPW) behind interventricular septum and left room gt; 1. 3- 1. 5 or the interventricular septum thickness gt; 15mm.
(2)The left room flows out a narrow lt; 20mm. If have obviously at the quiet interest flow out dishes of steps bad pressure, can employ inferior the intersection of nitric acid and different the intersection of fifth and ester bring out dynamics pressure steps poor, in order to exclude from flowing out one to obstruct. Colored the intersection of blood flow and formation of image can diagnose and judge it is compatible bicuspid valve that shut off the wholly. Can determine the relaxation function of left ventricle on the bicuspid valve or pulmonary vein blood flow speed curve.
(3)The intersection of bicuspid valve and in front of the systolic phase to move frontal lobe (SAM phenomenon) Contact with plump interventricular septum. 1/ 3 of the the end before systolic phase that SAM starts, keep in touch with the interventricular septum while shrinking interim 1/ 3, form the left room and flow out one is narrow. Aorta petal close ahead of time in systolic phase, present half lock state, when hold the intersection of relaxation and a issue of time, lengthen, reflect the left room is reduced.
(4)Relaxation issues of the intersection of bicuspid valve and frontal lobe and interventricular septum from little than the normal one.
(5)25% of the plump type myocardium disease patients have aorta one not to close completely, the obstructing plump type myocardium disease of great majority has backflow of bicuspid valve, a few getting plump person who obstruct myocardium disease have slight bicuspid valve shut off the whole too. A few patients can present room wall tumour.
(6)LVEF drops, the heart function changes and takes function obstacle of relaxation as the core.
