ABSTRACT

Objective:To explore the feasibility and clinical value of real time three‐dimensional transesophageal echo‐cardiography (RT‐3D TEE) in diagnosis of congenital heart valvular disease (CHVD).Methods:A total of 135 CH‐VD patients treated in our hospital were selected .All patients received surgery ,and transthoracic echocardiography (TTE) and RT‐3D TEE inspection successively within 7d before surgery .Heart valve lesion condition was observed , and diagnostic results of two methods and surgical outcome were compared and analyzed .Results:RT‐3D TEE could display the morphological structure ,lesion degree and peripheral blood flow of heart valves in CHVD patients in a multi‐angle ,stereoscopic and clear way .It could find heart valve disease which is difficult to be identified by TTE , and corrected the diagnostic deviation .With surgical results as the gold standard ,diagnostic coincidence rate of RT‐3D TEE was significantly higher than that of TTE (97. 04% vs.91. 11%, P＝0.039).CHVD diagnosed by RT‐3D TEE and TTE possessed a intermediate consistency (Kappa＝0.477 , P＝0. 001).Conclusion:RT‐3D TEE can pro‐vide more imaging information for the diagnosis of CHVD ,which can be used as an effective supplement for preop‐erative TTE examination .
