Systolic murmurs are often noted in elderly patients admitted to hospital (Monroe, 1951). They tend to be dismissed as of no clinical significance and due to aortic sclerosis (Bruns and Van der Hauwaert, 1958); rarely is origin from other valves considered. However, observations during earlier studies on other aspects of cardiovascular pathology in the aged (Pomerance, 1965, 1967) did not seem ...

Murmurs arise when blood flow becomes turbulent, causing vibration of cardiovascular structures. Physiological murmurs or functional murmurs result from turbulent flow associated with normal blood flows at high velocity. Pathological murmurs are caused by a pathological condition such as valvular regurgitation or congenital cardiac disease. When a murmur is diagnosed, we first need to identify ...

ISSN: 1652-6880, ISBN: 978-91-576-7323-7 Turbulence of various genesis in the left ventricular outflow tract (LVOT) causes systolic ejection murmurs.

Audible cardiac murmurs are uncommon and may indicate severe native valve dysfunction. In six patients with bioprosthetic mitral valves audible honking systolic murmurs suddenly developed. Doppler echocardiography showed characteristic striated regurgitant signals. At operation each prosthesis had torn cusps. New audible murmurs and striated Doppler signals originating from mitral bioprosthetic...

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. ...

For a number of years increasing attention has been paid to the evaluation of systolic murmurs (White, 1927; Fahr, 1930; Bass et al., 1933; Shapiro, 1939; White et al., 1942; Baker et al., 1943; Levy et al., 1943; Sodeman, 1944; and Master, 1948). It has been found that they are common in patients without evidence of cardiac disease, and the importance of considering factors other than organic ...

The prevalence of mitral valve prolapse was determined in two independent populations (6887 consecutive adults and children referred for echocardiography during a three year period and 206 non-referred first degree relatives of 65 patients with mitral valve prolapse). In the 118 adults with echocardiographic evidence of prolapse those aged greater than or equal to 50 years were significantly mo...
