The slope of an individual contrast trajectory on M-mode contrast echocardiography represents a physiological variable similar to that measured by Doppler echocardiography: the projection of the intracardiac velocity vector in the direction of the sound beam. To test the hypothesis that M-mode contrast echocardiography slope measurement can yield information quantitatively similar to Doppler me...

BACKGROUND Alteration of cardiovascular functions in patients with liver cirrhosis has been described and it correlates with severity of hepatic failure. But cardiac functions by conventional 2-dimensional (2-D) echocardiography has limitations. The aim of the study was to evaluate cardiac systolic and diastolic functions in liver cirrhosis patients with or without ascites by tissue Doppler ima...

AIMS This study uses pulsed Doppler tissue imaging to analyse right ventricular myocardial function and its interaction with left ventricle in hypertrophic cardiomyopathy involving ventricular septum. METHODS AND RESULTS Thirty-four patients with septal hypertrophic cardiomyopathy and 30 normal subjects, comparable for sex, age, body mass index and heart rate, underwent complete standard Dopp...

BACKGROUND Hemodynamic and functional evaluation with Doppler and tissue Doppler study as a part of comprehensive echocardiography is essential but normal reference values have never been reported from Korean normal population especially according to age and sex. METHODS Using Normal echOcaRdiographic Measurements in a KoreAn popuLation study subjects, we obtained normal reference values for ...

Background. The aim of this study is to show whether the septal E/(E' × S') ratio assessed by tissue Doppler echocardiography can predict left ventricular remodeling after first ST segment elevation myocardial infarction treated successfully with primary percutaneous intervention. Methods. Consecutive patients (n = 111) presenting with acute anterior myocardial infarction for the first time in ...

BACKGROUND We assessed the validity of the atrial electromechanical interval, measured by transthoracic tissue Doppler echocardiography, in determining patients at risk of post-coronary artery bypass graft atrial fibrillation (AF). METHODS AND RESULTS This prospective study recruited 355 patients in sinus rhythm who were candidates for coronary artery bypass grafting. The patients underwent a...

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...
