Abstract Objective: To investigate the diagnostic value of transthoracic right phonography (cTTE),transcranial Doppler foaming test (cTCD) and esophageal echocardiography (TEE) in patent foramen ovale (PFO). Methods: Clinical data of 140 patients with PFO closure in our hospital (group A) and patients without PFO in right heart catheterization (group B) were retrospectively analyzed and compared, including clinical baseline data, cTTE, cTCD and TEE. The differences in cTTE, cTCD shunt volume, TEE foramen ovale size and cTTE bubble appearance time were compared between the two groups. The ROC curve of these indicators in the diagnosis of PFO was drawn. Results: The proportion of medium-large shunt in cTTE was higher in group A than group B. The proportion of medium-large shunt in group A was higher than group B in resting,post-Valsalva and total respectively (67.35% vs. 42.86%, P=0.04; 100.00% vs. 71.42%, P<0.001; 81.63% vs.51.43%, P=0.004). The proportion of medium-large shunt in cTCD was higher in group A than group B (75.90% vs. 19.35%, P<0.001). The PFO diameter of group A was larger than group B in TEE (2.18±0.78 vs. 1.19±0.78,P<0.001). The ROC curves of cTTE, cTCD and TEE showed that the AUC of cTCD and TEE had larger and better sensitivity and specificity. The proportion of bubble appearance within 5 cardiac cycles in cTTE in group A was significantly higher than B (73.47% vs. 42.86%, P=0.007). Conclusion: cTCD and TEE have good predictive value for PFO, with better comprehensive value than cTTE.
