RESULTS In three patients, the mitral incompetence was caused by dilatation of the atrio-
ventricular ring; the long diameter of the mitral orifice measured 5* 0 cm. or more; there was …

Clinical, hemodynamic, and angiocardiographic findings are described in seven cases of
congenital mitral insufficiency. The volumes and changes in volume of the left atrium and left …

Three patients with mitral stenosis are described, in whom the haemodynamic findings at
cardiac catheterisation were more suggestive of left ventricular myocardial disease, in that …

Left ventricular function during systole and diastole was studied in 17 young patients with
mitral incompetence and sinus rhythm; 13 had established chronic mitral incompetence, 3 …

RESULTS Before Operation. Mitral valve flow was generally low, ranging from 59 to 190
ml./VFP sec.(Table I). The flow was considered below normal (Goldberg et al., 1956)(150 …

The clinical and hemodynamic findings in 10 patients with mitral insufficiency on a
congenital basis are described. Six of these patients have had repair of the defects with …

RESULTS The material was first analysed according to the criteria suggested by previous
workers. The height of the v wave, the vc difference, and the Ry/v ratio were determined and …

1. The end-diastolic pressure gradient between the left atrium and the left ventricle has been
determined at rest in 63 patients with mitral valvular lesion. The diagnosis was verified at …

Abnormalities of the mitral valve in patients with pulmonary stenosis, tetralogy of Fallot, and
pulmonary hypertension with right ventricular pressure overload were studied by real time …

There is general agreement among cardiologists that a co-existent mitral insufficiency does
not in itself represent a contraindication to commissurotomy in mitral stenosis, and that the …
