The value of echocardiography combined with right echocardiography in the diagnosis of Patent foramen ovale

Objective The esophageal echocardiography(TEE)and the contrast transthoracic echocardiography were investigated.Application value of cTTE in patent foramen ovale(PFO)diagnosis.Methods In this study,121 suspected PFO patients admitted to our hospital from August 2019 to October 2020 were selected as the research objects.All patients underwent TEE and cTTE tests.The detection rate of TEE and cTTE alone or in combination for PFO diagnosis and the detection rate of right to left shunt(RLS)were compared and analyzed.Results 112 cases of PFO were found by TEE examination in 121 suspected PFO patients,the detection rate was 92.56%(112/121).120 cases of PFO were found by cTTE examination,and the detection rate was 99.17%(120/121).TEE and cTTE combined examination revealed 121 cases of PFO,with a detection rate of 100.00%(121/121).The detection rate of PFO by cTTE was significantly higher than that by TEE(P<0.05),and the detection rate of PFO by TEE and cTTE combined examination was significantly higher than that by TEE alone(P<0.05),but there was no significant difference between cTTE and TEE alone(P>0.05).The detection rate of RLS by cTTE was significantly higher than that by TEE(P<0.05).Conclusion Compared with TEE alone,the detection rate of PFO by cTTE was significantly improved,and was similar to that by TEE combined with cTTE.cTTE can better reflect the situation of RLS,which can be used for reference and promotion in clinical practice.
