Description
Summary:Abstract Aims Unicuspid aortic valve (UAV) is a rare congenital malformation associated with severe aortic stenosis or regurgitation. This study aimed to systematically determine echocardiographic criteria to identify UAV. Methods and results All patients underwent a preoperative baseline examination, including echocardiography. A total of 69 patients with intraoperatively confirmed UAV underwent an aortic valve repair procedure between August 2001 and May 2011. To compare the findings of UAV cases with those of other valve morphologies, we examined 99 consecutive patients with a bicuspid aortic valve (BAV) and 103 consecutive patients with a tricuspid aortic valve (TAV) undergoing isolated aortic valve surgery before May 2016. The mean age of the 271 patients was 44.2 ± 12.8 years; 85% were male, with a mean body mass index of 26.2 ± 4.0 kg/m2. Patients with UAV were younger and had fewer co-morbidities than patients with BAV or TAV, respectively. The major criteria for the echocardiographic diagnosis of UAV were defined based on our preoperative examination as follows: (i) single commissural attachment zone, (ii) rounded, leaflet-free edge on the opposite side of the commissural attachment zone, (iii) eccentric valvular orifice during systole, and (iv) patient age 15 mmHg. The minor criteria were defined as an associated thoracic aortopathy and age
