[Mitral valve and left ventricular function in ostium secundum type interatrial communication, studied by left ventriculography]. / Estudio de la válvula mitral y de la función ventricular izquierda en la comunicación interauricular tipo ostium secundum por medio de la ventriculografía izquierda.

Clinical, hemodynamic and cineangiographic studies were performed in 11 patients with atrial septal defect (ASD) of ostium secundum type. Mitral valve prolapse was found cineangiographically in 9 cases. Systolic and diastolic left ventricular volumes were significantly increased, while left ventricular function and compliance were normal. A careful systematic exploration of mitral valve in patients with ASD ostium secundum seems to be advisable.
