Congenital Mitral Insufficiency

Congenital mitral insufficiency.

T HE INFREQUENT REPORTS of mitral insufficiency on a congenital basis rcflect the apparent rarity of this condition. Aneurysmal dilatation of the left atrium in a 5year-old girl with clinical findings suggesting mitral insufficiency has been described by Semans and Taussig in 1938.1 Postmortem examination of this patient revealed thickening of the mitral and tricuspid valves, saccular dilatatio...

Surgical correction of congenital mitral insufficiency.

J /1ost frequently, congenital mitral insufficiency is associated with other congenital heart defects, mainly of the endocardial cushion defect type. Clinical cases of isolated mitral insufficiency, although unusual,12 are being described with increasing frequency, and their clinical and pathologic features are being well documented.: Surgical correction of these uncommon types of isolated mitr...

Congenital mitral insufficiency with cleft posterior leaflet.

Anomalous mitral arcade. A type of congenital mitral insufficiency.

Described in three infants is an anomaly of the mitral valvular mechanism which has the following characteristic: connection of the left ventricular papillary muscles to the anterior mitral leaflet, either directly or through the interposition of unusually short chordae. The condition has been named "anomalous mitral arcade." The anatomic aberration appears to cause incompetence of the mitral v...

Interatrial Septal Defect with Mitral Insufficiency of Congenital Origin

Mortality due to uncomplicated congenital defects of the heart is comparatively infrequent. Cabot's analysis of 1,906 cardiac autopsies shows only seven cases of congenital defects, of which two were clinically recognized and in only one was the death solely due to the cardiac anomaly. Among the congenital cardiac disorders Muir and Brown (1934) consider that interventricular septal defects are...
