Abstract
|
|
|
The new color flow mapping Doppler technology provide a dynamic melted for studying the spatial distribution of blood flow in the heart, unlike any noninvasive or invasive technique previously available.
The aim of this observation is a grading of mitral insufficiency or aortic insufficiency by color Doppler flow mapping.
The subjects were 11 cases of mitral insufficiency and 14 cases of aortic insufficiency confirmed by cineangiography.
In all 11 cases of mitral insufficiency, regurgitant flows through miral valves were observed by color Doppler flow mapping and there was significant correlation between the grades of left ventricular angiography and color Doppler flow mapping.
Among 14 cares of aortic inssufficiency, regurgitant flows through aortic valves were observed in 11 cases by color Doppler flow mapping. There was significnt correlation also between the glades of ascending aortogram and color Doppler flow mapping. In 3 cases of aortic insufficiency combined with mitral stenosis, aortic regurgitant flows were masked by mitral stenotic jets.
Although some limitations of aliasing or signal to noise problems in deep structures are present, It appeares that this now technology will provide substantial opportunity in evaluating valvular regurgitaions.
