Isovolumic contraction time by pulsed-wave Doppler tissue imaging in aortic stenosis.
BACKGROUND Doppler Tissue Imaging (DTI) has been evaluated in ischaemic heart disease and some cardiomyopathies. In patients with aortic stenosis (AS), left ventricular contraction is slowered. This study aimed to evaluate the possible role of the measurement of isovolumic contraction time (ICT) by DTI in the evaluation of AS severity. METHODS The study population constitutes 30 patients: 15 ...
متن کاملEvaluation of aortic stenosis by continuous wave Doppler ultrasound.
Twenty-four patients with suspected aortic stenosis (Group I) were evaluated noninvasively by continuous wave Doppler ultrasound before undergoing cardiac catheterization. Twenty normal subjects served as the control group (Group II). Maximal velocity measurements in the ascending aorta ranged from 3.0 to 5.8 m/s (mean 4.34 +/- 0.65) in Group I versus 1.0 to 1.6 m/s (mean 1.28 +/- 0.16) in Grou...
متن کاملCardiac dysfunction in acromegaly: evidence by pulsed wave tissue Doppler imaging.
OBJECTIVE To verify whether the accuracy of data on myocardial function provided by pulsed-wave tissue Doppler imaging (PWTDI), a new echocardiographic application that allows quantitative measurements of myocardial wall velocities, could help towards a better understanding of the natural history of acromegalic cardiomyopathy. DESIGN Eighteen patients with active acromegaly (ten men and eight...
متن کاملNormal left ventricular systolic time intervals assessed by pulsed wave Doppler echocardiography in the Turkmen horse of Iran
The Turkmen horse is one of the oldest and purest breeds in the world. There is no information with regards to the normal echocardiographic parameters of this horse regarding to cardiac diseases. Pulsed-wave (PW) Doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing Turkmen horses. There were 26 stallions and 16 mares. The left ventricular isovolumetric contrac...
متن کاملEvaluation of left ventricular systolic function with pulsed wave tissue Doppler in rheumatic mitral stenosis.
BACKGROUND Mitral stenosis (MS) is still the most common complication of acute rheumatic fever in Turkey. Rheumatic carditis affects not only cardiac valves but also myocardium. In this study, we aimed to evaluate the subclinical left ventricular (LV) systolic dysfunction and contraction of short and long axial circumferential and longitudinal fibers by pulsed wave tissue Doppler in rheumatic M...
