Selective ventriculography is an effective imaging modality for identifying and localizing mitral valve ballooning, a condition often associated with chest pain and T-wave changes.
Mitral ballooning was proved by selective ventriculography in 24 cases. Description of the posterior mitral leaflet as a triscalloped structure allows identification of the site of ballooning in the right anterior oblique position: it is in the middle scallop if the prolapse is central, and posteromedial if it involves the posterior pole of the mitral valve. Visualization of a “doughnut-like” mitral valve indicates ballooning of both leaflets, as demonstrated at autopsy in one case. Selective coronary arteriograms performed on 10 patients were normal. This syndrome is common and often associated with chest pain and T-wave changes.
