Diastolic murmurs have always been considered abnormal, but this report presents nine apparently normal children with high-frequency, early, diamond-shaped diastolic murmurs confirmed by intracavitary phonocardiography to arise within the left ventricle. Each child (aged 5 to 15 years) was referred for evaluation of a systolic murmur at the lower left sternal border, but an additional finding a...

BACKGROUND The aims of this study were to establish the prevalence of innocent cardiac murmurs in clinically healthy puppies, to investigate a possible correlation between the presence of an innocent murmur and hematocrit, and to describe the auscultation characteristics of innocent murmurs. HYPOTHESIS Lower hematocrit contributes to the genesis of innocent murmurs. ANIMALS Five hundred and...

To clarify the postulate that turbulence may produce ejection murmurs, point velocity and sound were measured in the ascending aorta of 13 subjects: six with normal aortic valves, six with aortic valvular disease, and one with a Bjork-Shiley prosthetic aortic valve. Velocity was measured with a catheter-tip hot film anemometer probe, and sound was measured with a catheter-tip micromanometer. Ej...

Systolic murmurs in healthy children are common and occasionally cause difficulty in differential diagnosis. Our main object has been to make a graphic study of these murmurs in relation to rightand left-sided cardiac events and discuss their differentiation from organic murmurs. The opportunity has been taken to give some normal measurements used routinely in phonocardiography in our departmen...

PURPOSE The study compares the feasibility of the quantitative volumetric and semi-quantitative approach for quantification of chronic aortic regurgitation (AR) using different imaging modalities. METHODS left ventricular (LV) volumes, regurgitant volumes (RVol) and regurgitant fractions (RF) were assessed retrospectively by 2D, 3D echocardiography and cMRI in 55 chronic AR patients. Semi-qua...

BACKGROUND Although cardiac auscultation remains important to detect abnormal sounds and murmurs indicative of cardiac pathology, the application of electronic methods remains seldom used in everyday clinical practice. In this report we provide preliminary data showing how the phonocardiogram can be analyzed using color spectrographic techniques and discuss how such information may be of future...

Angiographic clinical correlations were made in 59 patients with prolapsed mitral leaflet syndrome. Eight had nonejection systolic clicks (group I), 20 had early, mid or late systolic murmurs with or without a systolic click (group II), and 31 had pansystolic murmurs (group III). Isolated prolapse of posterior leaflet (PL) scallops occurred in 42 and 17 had combined leaflet prolapse. The study ...

Thirty-nine elderly patients, mean age 77 years (range 65 to 96), with ejection systolic murmurs were studied to evaluate the functional significance of these murmurs. Subjects were evaluated clinically, by 2-D echocardiography, and by a full Doppler echocardiography study. Good quality Doppler signals were obtained in 35 subjects. Mitral regurgitation was found to be the only significant valvu...
