Abstract：Objective To analyze the clinical characteristics and echocardiography findings in patients with aortic valve prolapsed. Methods The patients (n=112) were chosen from the Outpatient Department of Affiliated Hospital of Chifeng University from May 20, 2013 to Sept. 30, 2017. The disease cause and general information were summed up in all patients. Echocardiogram was used to review the inner diameters of aortic sinus (Ao) and ascending aorta (AAo), left atrial anteroposterior diameter (LA), left ventricular end-diastolic inner diameter (LVEDd), left ventricular end-systolic diameter (LVESd), left ventricular ejection fraction (LVEF) and valve regurgitation. Results The average age was (48.83±13.73) and male percentage was 82.1% in 112 patients. The bicuspid aortic valve disease was the most common in all patients [n=28 (25%)], and 16 (14%) with infective endocarditis (IE), 7 (6%) with bicuspid aortic valve disease complicated by IE, 7 (6%) with aortic valve degeneration, 5 (4%) with ventricular septal defect (VSD), 3 (3%) with Marfan syndrome, 2 (2%) aortic dissection, 4 (4%) with aneurysm of sinus of Valsalva (SVA), and 3 (3%) with behcet disease. The results of echocardiogram showed that enlargement of left ventricular, mean LVEDd was (65.68±10.03), mean LVESd was (45.73±10.32) and LVEF was (56.70±9.63) and percentage of cases complicated by severe valve regurgitation (91.7%). The inner diameter of Ao was (37.36±7.88) mm and that of AAo was (38.67±6.85) mm and percentage of cases complicated by medium-severe pulmonary arterial hypertension (PAH) was 8.1%. The most common valve prolapsed occurred in right coronary valve (45.5%) in patients with tricuspid aortic valve disease, and left anterior valve prolapsed (15.2%) was common in patients with bicuspid aortic valve disease. Conclusion The causes of aortic valve prolapsed are commonly bicuspid aortic valve disease and IE. The direct sign is prolapsed of aortic valve to left ventricular outflow tract observed by echocardiogram, and percentage of right coronary valve prolapsed is the highest. The most patients are complicated by left ventricular enlargement and severe aortic valve regurgitation.
