Abstract：Objective To evaluate the value of integrated echocardiography in Ozaki operation in children with aortic valve malformation. Methods Ozaki operation was performed in 7 children with aortic valve malformation. Transthoracic 2-dimensional echocardiography (2 DE), Transthoracic 3-dimensional echocardiography (3DE) and transesophageal echocardiography (TEE) were performed before and after Ozaki operation. Results Compared with the surgical findings, aortic valve malformation was diagnosed correctly in 7 cases (100％) by 2 DE and 3DE, 2 cases with single coronary artery and 1 case with fistula between coronary artery and pulmonary artery were miss diagnosed. TEE and 2 DE were performed during and 3 months later of Ozaki operation, vena contracta width of aortic valve regurgitation was reduced significantly (0.64±0.25) cm vs (0.22±0.04) cm, (P＜0.01). Conclusion Integrated echocardiography could clearly demonstrate the number, size of aortic valve anomalies. It was valuable for patients selection before the operation, and evaluating the operative effects and was a safe and effective guidance technique. It was prone to be miss diagnosed for associated coronary artery anomaly.
