Quadricuspid aortic valve (QAV) is a rare congenital heart disease, and its long-term lesion type is mainly reflux. The application of transcatheter aortic valve replacement (TAVR) in such patients is extremely rare. This article reports a case of an elderly patient with QAV complicated with severe regurgitation and small subvalvular membrane. Through preoperative evaluation and guidance from the cardiac team discussion, a relatively high oversize rate retrievable valve was selected and the TAVR surgery was successfully completed. At the same time, the valve implantation depth was adjusted to cover the subvalvular membrane. After surgery, the patient’s symptoms such as palpitations were significantly improved. No obvious perivalvular leakage or regurgitation was observed. It provides a reference for TAVR surgical plans for such patients.
