Both M mode and two dimensional echocardiography are useful in determining the origin of
mitral regurgitation. Two dimensional echocardiography appears to be superior to M mode …

To test the role of recently developed biplane transesophageal color Doppler
echocardiography in the assessment of severity of mitral regurgitation, we examined 51 …

RESULTS The procedure was completed successfully in 24 of the 30 patients. It was
abandoned in 1 patient because of electrocardiographic changes due to catheterization of a …

Accurate clinical assessment of the severity of mitral regurgitation is often difficult, and left
ven-tricular cine-angiocardiography is probably the most commonly used methodof …

Preoperative cardiac catheterization of patients with valvular heart disease is the currently
accepted standard method to confirm the diagnosis, exclude other significant valve lesions …

When open operations are performed for the repair of malformations of the mitral valve, the
associated aortic regurgitation may prove a serious technical handicap. It is desirable …

Partial detachment of a mitral ball-valve prosthesis, resulting in left ventriculo-atrial
regurgitation, may be responsible for persistent symptoms of diminished cardiac reserve …

The value of left ventricular angiocardiography in the assessment of mitral regurgitation has
been critically analysed. 2. The main radiological sign of importance and value is the …

Before the development of color Doppler, coventiona! pulsed Doppler echocardiography
had been used to detect the presence of valvular regurgitation because it provided …

The purpose of this study was to evaluate whether the degree of valvular regurgitation could
be reliably estimated by digital subtraction angiography using a 0 to 4+ scale of …
