Effect ofRight Contrast Echocardiography in Different Positions on the Diagnosis of Patent Foramen Ovale
摘要
Abstract
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 Sec-ond 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 a-gents 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.关键词
