title: [Hemodynamic aspect of infundibular hypertrophy of pulmonary valve stenosis].
abstract: Reactional infundibular hypertrophy in pulmonary valve stenosis is usually assessed on the catheterization curves obtained in the infundibulum and in the inflow tract of the right ventricle. It is usually indicated by a peculiar pattern of the infundibular curve: its descending branch is more rapid than in the inflow tract and is slightly curvilinear. This deformity is the more marked the more intense the hypertrophy. Simultaneously a mid-late systolic murmur is recorded into the infundibulum the more intense and high-pitched the more marked the hypertrophy. Comparison with the angiocardiographic data and the operative findings showed a good correlation.
