Abstract：Objective To investigate the advantages of real-time three-dimensional transesophageal echocardiography(RT 3D-TEE) in percutaneous closure of prosthetic paravalvular leakage(PVL).Methods Ten patients with PVL(totally 10 leakages) undergoing percutaneous closure therapy from December 2015 to February 2017 in Beijing Anzhen Hospital,Capital Medical University were enrolled.RT 3D-TEE and two-dimensional transthoracic echocardiography(2D-TTE) were performed before interventional procedure;2D-TTE was used to observe the short-term surgery success rate and echocardiographic changes in 3 months.Results RT 3D-TEE detected 5 PVLs at anterior location,4 PVLs at posterior location and 1 PVL at lateral location.There was a significantdifference between 2D-TTE and RT 3D-TEE in measuring the maximum diameter of leakage[(5.0 ± 1.6) mm vs (9.4 ±3.3) mm] (P =0.001).Reflux degree significantly decreased after operation compared to that before operation in all patients [(1.7 ± 1.2) cm2 vs (7.3 ± 2.8) cm2] (P =0.019).Left ventricular end-diastolic dimension,left atrial diameter and the New York Heart Association classification of cardiac function grade Ⅲ ratio significantly reduced after operation compared to those before operation [(57 ± 8) mm vs (58 ± 8) mm,(55 ±17) mm vs (57 ± 17) mm,1/9 vs 7/10] (P ＜ 0.05).Conclusion Echocardiography is a reliable tool for assessment of PVL;RT 3D-TEE is superior to 2D-TTE in measuring the form and size of PVL.
