摘要
目的探讨两种不同体位超声心动图右心声学造影在卵圆孔未闭(PFO)诊断中的价值。方法选取2022年1月至2024年3月在常德市第二人民医院住院治疗的63例疑PFO患者,均给予经胸超声心动图(TTE)检查。检查时,同一患者均分别采取右侧卧位45°与左侧卧位45°两种体位;将生理盐水8 ml与自体静脉血1 ml及空气1 ml激活作为造影剂,进行快速静脉推注。两种体位均分别进行静息状态下和Valsalva发泡试验,观察3~6个心动周期内左心微气泡显影数量,比较两种不同体位左心腔内右向左分流微气泡数量。结果左心内微泡数量RLS分级结果显示,右侧卧位静息显影率为73.6%,大于左侧卧位的45.3%;Valsalva试验结果显示,右侧卧位显影率为88.6%,大于左侧卧位的75.5%,P<0.05。结论采取右侧卧位可提高TTE右心声学造影中PFO患者检出率。
Objective:To explore the value of right contrast echocardiography in the diagnosis of patent foramen ovale(PFO)in two different postures.Methods:Sixty-three suspected PFO patients hospitalized in Changde Second People's Hospital from January 2022 to March 2024 were examined by transthoracic echocardiography(TTE).At the time of examination,the same patient took two postures:right lateral position 45 and left lateral position 45 respectively.8 ml of normal saline,1 ml of autologous venous blood and 1 ml of air were activated as contrast agents for rapid intravenous injection.At rest and Valsalva foaming tests were carried out in both postures,and the number of left ventricular microbubbles developed in 3~6 cardiac cycles was observed,and the number of right-to-left shunt microbubbles in the left ventricular cavity of the two different postures was compared.Results:RLS classification of the number of microbubbles in the left heart showed that the resting development rate in the right lateral position was 73.6%,which was higher than that in the left lateral position(45.3%).The results of Valsalva test showed that the development rate of right lateral position was 88.6%,which was higher than that of left lateral position(75.5%),P<0.05.Conclusion:The right lateral decubitus position can improve the detection rate of PFO patients in transthoracic echocardiography.
