MITRAL INSUFFICIENCY

Mitral Valve Insufficiency

The causes of mitral valve insufficiency may largely be divided into two categories: organic or primary and functional or secondary. In the first case, the cause of insufficiency is due to a morphological change of the valve. Numerous diseases may damage the valve. Of the degenerative disease we may list myxomatous degeneration, fibroelastic deficiency or annular calcifications. Of the phlogist...

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...

Nonrheumatic Mitral Insufficiency

Twenty patients with mitral insufficiency (MI) due to ruptured chordae tendineae, papillary muscle infarction, or left ventricular enlargement with no organic disease of the mitral valve have been studied during the past 3 years. Nineteen had valve replacement, and one had plastic repair of ruptured chordae tendineae; all have been followed from 6 months to 3 years. Preoperative data were diffe...

Surgery for Mitral Insufficiency

SINCE the earliest reports,' 2 in 1957, of the successfult surgical correction of mitral insufficiency under direct vision, a vast amount of new knowledge, both experimental and clinical, has accumulated, and considerable progress has been made in the treatment of this cardiac defect. Much of this new knowledge was discussed at a conference on prosthetic valves3 in Chicago during September 1960...
