  1. A 70-year-old man with symptomatic aortic stenosis and regurgitation was referred for transcatheter aortic valve replacement. Pre-procedural computed tomography showed a quadricuspid aortic valve (QAV) . The annular perimeter and area were 83.3 mm and 527.7 mm 2, respectively.

    To learn from this procedure and sizing in the setting of QAV, we retrospectively performed patient-specific computer simulation (FEops HEARTguide, FEops, Ghent, Belgium) (1).Briefly, a computed tomography-derived 3-dimensional model of the aortic root and valve was first created (segmentation), followed by the generation of high-quality meshes of the aortic root and valve.

    Introduction. Quadricuspid aortic valve (QAV) is a rare congenital anomaly, with an incidence of 0.006 to 0.04% based on autopsy and echocardiography data (1, 2).Leonardo da Vinci first described the anatomical morphology of the QAV in his anatomical drawings more than 500 years ago ().However, the characteristics, natural history, and specific recommendations for the management of patients ...

    Background: Quadricuspid aortic valve (QAV) is a rare congenital malformation that can present with aortic regurgitation or aortic stenosis (AS)), requiring surgical treatment. Transcatheter aortic valve replacement (TAVR) is an alternative treatment for older patients and its prognosis for QAV therapy remains challenging.

    QAV is a rare congenital heart disease with an incidence of 0.006%, and often associated with aortic regurgitation, whereas stenosis is uncommon. 1 Although TAVR has become a widespread treatment of tricuspid and bicuspid aortic stenosis, few reports of TAVR for stenotic QAV exist. 2, 3 Previously reported cases were of relatively equal QAVs. To our knowledge, this is the first report of ...
