M-mode echocardiography was performed in 54 patients 1 month to 3 years after mitral valvotomy for dominant mitral stenosis. The mitral valve closure index (MVCI), an index previously shown to correlate well with the calculated mitral valve area, was used to diagnose residual mitral stenosis. Using the equation MVCI = 33 MVC--12, 12 patients (22%) were deemed to have mild, 4 (7%) moderate, and ...

rx-tHE object of this paper is to discuss the use of nitrous X oxide supplemented with pethidine in the operation of mitral valvotomy for the relief of mitral stenosis. Direct surgery of the stenosed mitral valve is no new conception. Indeed, as far back as the year 1902, Brunton put forward the plea for surgical disruption of the stenosed valve, but he met with such determined opposition that ...

Severe pulmonary hypertension due to an increased hindrance to blood flow in the small pulmonary arteries frequently complicates mitral stenosis, and when this occurs electrocardiographic evidence of right ventricular hypertrophy (RVH) is invariably present. Mitral valvotomy is commonly undertaken in patients with such changes, though their reversibility is the subject of controversy and opinio...

Twenty children with pulmonary valvular stenosis were studied by cardiac catheterization both at rest and during submaximal supine exercise, prior to and following pulmonary valvotomy. The resting and exercise states were comparable preoperatively and postoperatively since cardiac output, heart rate, A V 02 difference and oxygen consumption were similar. Evidence of improved cardiac function wa...
