OBJECTIVE To study the prevalence and the characteristics of physiological valve regurgitation. DESIGN Pulsed wave Doppler echocardiography, continuous wave Doppler echocardiography and Doppler colour flow mapping were performed prospectively in healthy volunteers. SETTING Echocardiography laboratory in a city hospital. PATIENTS 32 consecutive healthy volunteers (age 21-49 years, mean age...

Introduction Diastolic dysfunction was recently recognized as an important cause for heart failure in patients with preserved ejection fraction. Diastolic dysfunction is typically assessed in clinical routine using transmitral and pulmonary-venous flow characteristics by Doppler-echocardiography. We hypothesized that VENC-MRI has a similar ability to identify patients with diastolic dysfunction...

Background: Echocardiographic findings of Tetralogy of Fallot (TOF) are diagnostic in infants and young children, and echocardiography may be the only examination required prior to surgery. Global left ventricular function determined by conventional Doppler may be normal in these patients; but regional myocardial function assessment by tissue Doppler if abnormal in these patients may affect out...

Background The Poiseuillian model of the arterial system currently applied in clinical physiology does not explain how arterial pressure is maintained during diastole after cessation of pulsatile aortic inflow. Arterial pressure-flow relations can be more accurately described by models that incorporate arterial viscoelastic properties such as arterial compliance. Continuous pressure and flow me...

some limitations and it is unable to detect small abnormalities beyond the imaging resolution of the apparatus. Ventricular septal defects (VSDs) can only be detected if they are sufficiently large or are associated with certain anatomical malformation (Magherini et al., 1983). Accurate demonstration of a patent ductus arteriosus (PDA) is limited due to echo dropout which makes visualisation of...

Antemortem diagnosis of a perforated MV aneurysm by Doppler echocardiography, as well as two-dimensional echocardiography (2-DE), has not been reported. Herein we present such a case.

The year 2013 marked the 60th anniversary of Inge Edler and Hellmuth Hertz's discovery of echocardiography and the 160th anniversary of the death of Christian Andreas Doppler (1803–1853). The work of these pioneers marked modern cardiology not only by providing a more accurate diagnosis of heart disease but also by guiding patients' management. Echocardiography has to be included among the top ...

PURPOSE OF REVIEW To reiterate the necessity of integrating echocardiography in the management of shocked patients and to propose a step-by-step functional evaluation of hemodynamics proven to optimize hemodynamic monitoring and to adapt the treatment. RECENT FINDINGS Echocardiography has become the cornerstone to hemodynamic monitoring. By providing real-time images, echocardiography has the...

Methods Seventy fetuses at 19 to 28 weeks of gestation with an IEF and 63 controls were screened using two-dimensional and power Doppler echocardiography. DV wave velocities, DV velocity ratios, and diastolic time intervals were measured. The aortic peak velocity, pulmonary artery peak velocity, atrioventricular early-diastolic filling velocity (E), atrial contraction velocity (A), and E/A rati...

The Doppler echocardiographic features of coronary arteriovenous fistula were investigated in eight patients with left or right coronary arteriovenous fistulas who had a continuous heart murmur in the upper precordial area and whose diagnoses were confirmed by coronary angiography. In four patients the dilated lumen of the coronary arteriovenous fistula was visualised by cross sectional echocar...
