“…The patient is not currently undergoing surgery because there is no significant valve regurgitation or stenosis. However, with aging, valve elasticity decreases, which will aggravate valve dysfunction [ 25 ]; therefore, long-term follow-up of this patient is essential.…”

“…The double orifice mitral valve (DOMV) is considered a rare congenital heart malformation due to the abnormal embryonic development of the endocardial cushion and myocardium, characterized by a two-channel atrioventricular valve in the left ventricle and accounting for about 0.05% of all congenital heart diseases [ 1 , 2 ]. The two orifices of the mitral valve (MV) can be symmetrical or asymmetrical, isolated or exist with other cardiac malformations, and can be divided into complete bride type, incomplete bridge type, or hole type [ 3 , 4 ]. A bicuspid aortic valve (BAV) is relatively common and is characterized by the abnormal fusion of two leaflets of the aortic valve (AV) during development, resulting in a two leaflet valve instead of the normal tricuspid AV [ 5 ].…”

Background Patients with both double orifice mitral valve (DOMV) and bicuspid aortic valve (BAV) malformation are rare. Although DOMV or BAV can be detected in some genetic syndromes, it has not been reported to simultaneously appear in Turner syndrome (TS). TrueVue, TouchVue, and TrueVue Glass are the latest technologies in advanced three-dimensional echocardiography (3DE), which is an important information supplement to two-dimensional echocardiography (2DE) for the diagnosis of congenital cardiac malformations. Herein we report the novel use of the above-mentioned technologies in the diagnosis and evaluation of a rare, combined valve malformation. Meanwhile, we also reviewed the literature for cases involving both DOMV and BAV and their association with various genetic syndromes. Case presentation We present the case of a 5-year-old girl diagnosed with TS because of a developmental delay. DOMV and BAV were found through echocardiographic examination. Three-dimensional transthoracic echocardiography as well as a series of novel advanced techniques were applied to clearly display the spatial structure of all tiers of the mitral valve apparatus, aortic valve, and arch to facilitate an accurate diagnosis. Conclusions This is the first case in which both DOMV and BAV were associated with TS. Innovative TrueVue and TrueVue Glass offer unprecedented photographic stereoscopic images, while TouchVue technology greatly improved the ultrasonic diagnostic workflow and the diagnostic performance of rare valve malformations by adding virtual light sources to display realistic light-shadow effects.
