Why the study?
Can cineangiocardiography demonstrate the prolapsing mitral leaflet in patients with systolic click and murmurs?
Can cineangiocardiography demonstrate the prolapsing mitral leaflet in patients with systolic click and murmurs?
Cineangiocardiography in the left anterior projection is effective for visualizing posterior mitral leaflet prolapse and subsequent late systolic mitral insufficiency in patients with systolic clicks and murmurs.
May demonstrate posterior mitral leaflet prolapse and late systolic insufficiency on cineangiography in left anterior projection; leaves open clinical adoption pending further study.
Abnormal billowing or protruding of the mitral posterior leaflet can be demonstrated cineangiocardiographically in patients with a systolic click and late or midsystolic murmurs. Diverse etiologic factors have been offered to explain the prolapsing leaflet. Cineangiograms of patients demonstrate varying degrees of mitral insufficiency occurring late in systole subsequent to maximum prolapse of the valve. The left anterior projection is necessary to define the prolapsing leaflet which in our patients was the posterior leaflet.
