先天性主动脉瓣瓣上、瓣下狭窄的造影诊断及其评价

Angiocardiographicdiagnosticevaluationofcongenitalsupravalvularandsubvalvularaorticstenosis

目的：探讨先天性主动脉瓣瓣上、瓣下狭窄心血管造影诊断的价值。材料和方法：分析２４例先天性主动瓣瓣上、瓣下狭窄的心血管造影所见并与超声心动图比较。瓣上狭窄８例，瓣下狭窄１６例。结果：瓣上狭窄造影征象以升主动脉根部局限性环形狭窄最为常见（７例），瓣下狭窄造影示有主动脉瓣下１～２０ｍｍ处局限性狭窄，表现为环形透亮带（１０例）或切迹（３例）等。结论：瓣上狭窄的造影征象明确、可靠，优于超声心动图；瓣下狭窄造影所见有时不够明确，超声心动图优于造影。
