  • Transcatheter aortic valve replacement for a patient with bicuspid aortic valve stenosis characterized by leaflet thickening: a case report

    Due to the lack of calcification of the aortic valve, it is difficult to provide effective support for the fixation of artificial valve in aortic stenosis characterized by leaflet thickening. There is a risk of postoperative perivalvular leakage and secondary valve implantation, which is widely regarded as a relative contraindication for transcatheter aortic valve replacement (TAVR). But aortic valvuloplasty and self-expanding transcatheter aortic valve has showed its safety and efficacy. This paper reports a patient with bicuspid aortic valve characterized by leaflet thickening treated with TAVR. After the operation, the patient’s symptom of exertional dyspnea was significantly improved, New York Heart Association class increased to Ⅱ, no perivalvular leakage was found, and the mean transaortic pressure gradient and the maximum aortic valve velocity decreased significantly.
