Echocardiography in diagnosis of congenital unicuspid aortic valve / 中国医学影像技术

ABSTRACT

Objective: To explore the value of echocardiography in diagnosis of congenital unicuspid aortic valve (UAV). Methods: Totally 20 patients with UAV diagnosed by echocardiography were retrospectively analyzed. Results: Valve dysfunction was observed in all 20 patients. Simple stenosis of aortic valve was found in 6 cases (6/20, 30.00%), while simple regurgitation was detected in 3 cases (3/20, 15.00%).Two cases (2/20, 10.00%) showed no attachment point, 18 cases (18/20, 90.00%) showed attachment point mostly located in 1-7 o'clock. The ascending aorta enlarged after narrowing in 17 cases. Nine cases were found with other congenital heart diseases, while complications were noticed in 4 cases. Conclusion: Echocardiography can diagnose congenital UAV at early stage by showing the anatomy and movement of UAV in real time, providing reliable basis for treatment and prognosis assessment.
