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.
肺动脉瓣狭窄时反应性漏斗部肥厚通常根据在漏斗部及右心室流入道所获得的导管检查曲线来评估。它通常由漏斗部曲线的一种特殊形态所提示：其下降支比流入道的下降支更陡，且略呈曲线状。肥厚越严重，这种畸形就越明显。同时，在漏斗部可记录到中晚期收缩期杂音，肥厚越明显，杂音就越响亮、越尖锐。与心血管造影资料及手术所见的比较显示有良好的相关性。
