A 60-year-old male with previous hypertension, left ventricle hypertrophy, and coronary artery disease was referred for stress echocardiography because of exertional chest pain. The electrocardiogram revealed deep T-wave inversion in the anterolateral leads. Contrast echocardiography was notable for an apical filling defect consistent with the apical form of hypertrophic cardiomyopathy. Cardiac...

OBJECTIVES This study was conducted to assess the diagnostic role of Doppler echocardiography in constrictive pericarditis. BACKGROUND It has been observed that patients with constrictive pericarditis have a characteristic Doppler pattern of respiratory variation in ventricular filling and central venous flow velocities. However, the observation was based on a small number of patients with kn...

2 Introduction The assessment of left ventricular function is one of the most clinically important and frequently requested tasks in echocardiography. We are witnessing a progressive development in echocardiographic methods and techniques including the use of higher frequency transducers, tissue Doppler, harmonic imaging and trans-pulmonary or left sided contrast agents.

Cardiac output (CO) is routinely assessed by pulsed-wave Doppler echocardiography, yet reference values in adults are lacking. We aim to establish normative of CO and cardiac index (CI) Doppler-echocardiography analyze their relation with gender age nonobese obese adults. included 4,040 (mean age: 55 years, 53% women, 950 [body mass ?30 kg/m²]) normal blood pressure, no history cardiovascular d...

The advent and evolution of 2D echocardiography with Doppler gave a new dimension to the evaluation of valvular heart disease (VHD) and noninvasive cardiovascular hemodynamics. Extending from basic M-mode evaluation to the more sophisticated Doppler techniques, the way one looks at the valve anatomy and physiology has changed significantly. Doppler echocardiography has become the everyday tool ...
