METHODS Echocardiographic and anthropometric measurements were performed in 2,293 individuals who participated in the echocardiographic substudies of population-based MONICA Augsburg surveys. In addition, a total of 319 siblings of survey participants with echocardiographic evidence of LVH were evaluated. The risk of these siblings to present with LVH or abnormal LV geometry was estimated by co...

Current recommended reference ranges for echocardiographic measurements may not be relevant to the diverse world population they are applied to. A new study, the echocardiographic normal reference ranges of the left heart (EchoNoRMAL) study, is an individual person data meta-analysis of standard echocardiographic measurements which aims to re-define normal reference ranges of left heart dimensi...

Clinical, electrocardiographic, phonocardiographic, and echocardiographic examinations were performed in 100 presumably healthy young females. Treadmill testing and ambulatory electrocardiographic monitoring were performed in a selected group of these subjects. Phonocardiograms, recorded with the subjects supine at rest, after inhalation of amyl nitrite, and in the upright position, revealed a ...

background: mitral valve prolapse (mvp) is now recognized as the most common cardiovalvular abnormality (cva) in the usa, but there has been much less agreement about other aspects of its epidemiology, diagnosis and clinical features. cva analysis still relies mainly on the visual assessment of echocardiographic imaging and manual measurements by experienced cardiologists. so, automating or sem...

conclusions the coronary sinus flow per minute is the most accurate parameter among the three echocardiographic parameters mentioned above for the assessment of significant stenosis of the coronary artery. results flow (ml/minute), flow/lvm (ml/minuteg) and lv (d-s) mass a-l all correlated significantly with the percentage of stenosis (r = -0.64, p < 0.001; r = -0.47, p < 0.001; r = -0.56, p < ...

Objective- The purpose of this study was to investigate the feasibility of performing echocardiography in apparently healthy pigeons, and measurement of the quantitative cardiac indices using B-mode and Doppler techniques. Design- Experimental study Animals- Ten apparently healthy pigeons Procedures- Echocardi...

Background Standard mitral valve replacement (MVR) in patients with chronic mitral regurgitation results in consistent reductions in resting postoperative ejection fraction. This has been attributed to removal of the low-impedance ejection pathway into the left atrium or to disruption of the chordal apparatus. Mitral valve repair (MVP) does not reduce ejection fraction at rest. However, whether...

The clinical differentiation of hypertensive heart disease from hypertrophic cardiomyopathy usually presents no problem but it is less clear whether an echocardiographic distinction can always be made and, if so, what those echocardiographic criteria of difference are. It can be inferred from recent publications that when echocardiographic criteria for hypertrophic cardiomyopathy are met in hyp...

BACKGROUND Rheumatic Heart Disease (RHD) remains a major cause of childhood acquired heart disease in developing countries. However reported echocardiographic features are limited to a few countries. This report is on the demographic and echocardiographic features of RHD in children using data from the largest referral hospital in Yaounde, the capital city of Cameroon. METHODS The register of...

OBJECTIVES The aim of this study was to investigate the frequency and clinical implications of a delayed echocardiographic response to cardiac resynchronization therapy (CRT). BACKGROUND Long-term prognosis for CRT patients is routinely based on the assessment of echocardiograms after 6 to 12 months of therapy. Some patients, however, may require a longer period of therapy before echocardiogr...
