BACKGROUND Color M-mode Doppler echocardiography has been suggested as a new noninvasive technique for assessing left ventricular diastolic function. The present study investigated intraventricular filling pattern by color M-mode Doppler in patients during percutaneous transluminal coronary angioplasty (PTCA). In a dog model of myocardial ischemia, the color M-mode flow pattern was related to i...

BACKGROUND Although echocardiography is a useful and cost-effective technique for the detection of morphological and functional cardiac abnormalities, it has a main limitation in its subjectivity. Therefore the aim of the present study was to assess the intra-observer reproducibility and validity of 2-dimensional guided M-mode echo measurements at a Nigerian metropolitan Hospital. METHODS Sta...

We reviewed the M-mode and two-dimensional echocardiograms of 100 consecutive patients with rheumatic heart disease. All were subsequently studied by cardiac catheterization and angiography. In four patients, cardiac catheterization showed tricuspid stenosis (average mean diastolic gradient 6.2 mm Hg), which was confirmed during cardiac surgery. M-mode echocardiography showed a diminished EF sl...

Cross-sectional echocardiographic (CSE) studies were obtained in 29 children with tetralogy of Fallot. In this study we evaluated the capability of CSE to record the right ventricular outflow tract (RVOT) and compared the severity of infundibular obstruction determined by CSE with cineangiographic (cine) determinations. In addition, we examined capabilities of CSE and M-mode echocardiography (M...

This report describes a spectrum of M-mode and cross-sectional echocardiographic abnormalities in eight patients with infective endocarditis of the tricuspid valve. The M-mode echocardiogram of the tricuspid valve was abnormal in all but one patient in whom abnormal echoes were seen anterior to the tricuspid valve, in the right ventricular cavity and right ventricular outflow tract. Six patient...
