Natural history of innocent heart murmurs in newborn babies: controlled echocardiographic study

Natural history of innocent heart murmurs in newborn babies: controlled echocardiographic study.

AIM To define the origin and the natural history of innocent heart murmurs in newborn infants. METHODS Fifty healthy babies born at term with the clinical diagnosis of an innocent heart murmur and 50 controls without a murmur were studied. Each baby had a complete two dimensional and pulsed Doppler echocardiogram and those with any abnormality were followed up at 6 weeks, 3 months, and 6 mont...

Genesis of Still's murmurs: a controlled Doppler echocardiographic study.

OBJECTIVE The origin of innocent systolic murmurs is uncertain. This study was designed to evaluate the relative contribution in the same subjects of the main factors implicated in the genesis of vibratory innocent systolic murmurs--that is, the presence of left ventricular bands and increased left ventricular flow indices--and to examine evidence for turbulence in relation to these findings. ...

Innocent murmurs and third heart sounds in Black schoolchildren.

Normal auscultatory findings were studied during a heart survey in which 12 050 Black schoolchildren, aged 2 to 18 years, were examined by cardiologists. Physiological third heart sounds were detected in 96 per cent of children, innocent systolic murmurs in 72 per cent, and innocent mid-diastolic murmurs in 0.27 per cent. The term 'innocent systolic murmur" was used for vibratory systolic murmu...

Innocent Heart Murmurs from the Perspective of the Pediatrician.

Innocent heart murmurs are quite common in children and adolescents. These murmurs are physiologic in nature and are not associated with any structural heart disease. Not only does the idea of having a child with a murmur bring unnecessary unrest to families, but the child also often goes through numerous tests that could be avoided. It is critical to obtain a detailed history and perform a tho...
