Continuous-wave Doppler echocardiography was used to estimate pulmonary artery pressures by measuring pulmonary regurgitant flow velocity in 21 patients with pulmonary hypertension (mean pulmonary artery pressure 20 mm Hg) and 24 patients without pulmonary hypertension. The pulmonary regurgitant flow velocity patterns, characterized by a rapid rise in flow velocity immediately after closure of ...

PURPOSE To evaluate the reliability of 16-slice multidetector computed tomographic (MDCT) angiography for the preoperative morphologic assessment of coarctation of the aorta in adults. MATERIALS AND METHODS Twenty-four adult patients with clinical suspicion of coarctation of the aorta who underwent both Doppler echocardiography and MDCT angiography were included in this study. The sensitiviti...

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...

Pulmonary hypertension has been associated with poor outcome after liver transplantation. We assessed the diagnostic accuracy of Doppler echocardiography in detecting significant pulmonary hypertension. Seventy-four potential liver transplant candidates underwent Doppler echocardiography in which the systolic right ventricular pressure (RVsys) was used to estimate the systolic pulmonary artery ...

Thirteen fetuses with persistent arrhythmias underwent combined noninvasive echocardiographic evaluation utilizing M-mode, two-dimensional and pulsed Doppler echocardiography. This group (Group A) was compared with 14 fetuses in which only two-dimensional and M-mode echocardiographic evaluations were performed (Group B). In both groups correct prenatal interpretation of the arrhythmia was confi...

1. Rudski LG . Point: can Doppler echocardiography estimates of pulmonary artery systolic pressures be relied upon to accurately make the diagnosis of pulmonary hypertension? Yes . Chest . 2013 ; 143 ( 6 ): 1533 1536 . 2. Rich JD . Counterpoint: can Doppler echocardiography estimates of pulmonary artery systolic pressures be relied upon to accurately make the diagnosis of pulmonary hypertension...

BACKGROUND Doppler echocardiography is currently applied for the assessment of left ventricular and right ventricular hemodynamics in patients with cardiovascular disease. However, there are conflicting reports about its accuracy in patients with unstable decompensated heart failure. The objective of this study was to evaluate the accuracy of the technique in patients with unstable heart failur...

We tested the hypotheses that Doppler echocardiography has a higher accuracy than clinical evaluation in the detection of significant aortic and mitral valvular heart disease and that Doppler echocardiography is highly accurate as compared with cardiac catheterization for the assessment of valvular disease severity. Thus, cardiac catheterization for the assessment of valve lesion severity may b...
