Twenty-three patients with congenital subvalvular aortic stenosis are reviewed. The importance of classifying this stenosis into four types based on angiocardiographic findings is stressed, as are the indications for left heart catheterization during the preoperative and postoperative course of the disease. The type of congenital subvalvular aortic stenosis should be an important consideration during the discussion of operative indications in both asymptomatic and symptomatic patients.
对23例先天性主动脉瓣下狭窄患者进行了回顾性研究。强调了根据心血管造影结果将这种狭窄分为四种类型的重要性，以及在疾病的术前和术后过程中进行左心导管检查的指征。在讨论无症状和有症状患者的手术指征时，先天性主动脉瓣下狭窄的类型应是一个重要的考虑因素。
