摘要: Sixty-four children with pulmonary stenosis were studied by cardiac catheterization both at rest and on exercise. Whereas milder degrees of associated normal right ventricular function, more severe was fixed stroke index elevated RVEDP, suboptimal response index. These changes result from altered compliance. In several the compliance abnormality related to myocardial hypertrophy, whereas in four patients it most likely caused fibrosis.
