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...

Two cases of loculated pericardial effusion resulting in cardiac tamponade are presented. The loculated nature and extent of the effusion was best defined by two-dimensional echocardiography or B- mode ultrasonography. Cross-sectional images should probably be obtained in all cases of suspected loculated pericardial effusion and in patients in whom the interpretation of the M-mode echocardiogra...

The Boxer dogs have high predisposition to show dilated cardiomyopathy (DC). Consequently the evaluation of the left atrium size is important to the assessment of the severity of this disease. In the present study, the aortic root (AO) and left atrium (LA) dimensions were evaluated using two-dimensional (2D) and M mode (M) echocardiography in 36 healthy Boxer dogs. There were used 18 males and ...

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...

turkmen horse is one of the oldest and purest breeds in the world, but there is no information on doppler echocardiographic parameters in this horse. in the present study, pulsed-wave (pw) doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing turkmen horses. no cardiac disease was detected with two-dimensional (2-d) real-time, m-mode, and colour flow mapping. d...

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...

Twenty nine patients with isolated perimembranous ventricular septal defects were investigated by M mode, cross sectional, and pulsed Doppler echocardiography. Tricuspid valve anomalies were present in all six patients with a left ventricular-right atrial shunt but in only six (26%) of 23 patients who had interventricular shunts only. Systolic flutter of the tricuspid valve was shown in five (8...

M-mode echocardiography has been accepted as gold standard for measuring left atrial (LA) size. Electrocardiography (ECG) offers a simple, non-invasive, cost-effective and reproducible method to assess LA size and it is mostly in agreement with echocardiography though discrepancies exist. ECGs and echocardiograms were obtained in 100 consecutive patients suspected of having left atrial enlargem...

Three hundred and five patients routinely referred to a general hospital were surveyed to assess the advantages of cross-sectional echocardiography (CSE) over the conventional M mode method. CSE provided a dynamic display of the movement of the heart, particularly left ventricular function, and facilitated the location of cardiac structures. It was valuable in assessing the degree of mitral ste...

Background: Conventional echocardiography and tissue Doppler imaging have been highlighted to diagnose diastolic and systolic heart dysfunction. We aimed to compare tissue Doppler imaging with conventional echocardiography to diagnose heart dysfunctions in diabetes mellitus type 1 (DMT1) patients. <s...
