Two Cases of Quadricuspid Aortic Valve with Aortic Regurgitation / 日本心臓血管外科学会雑誌

ABSTRACT

Congenital quadricuspid aortic valve is a very rare malformation. We report two cases with severe aortic regurgitation due to isolated quadricuspid aortic valve. It consisted of three equal cusps and one smaller cusp, which was identified at the time of valve replacement surgery for severe aortic regurgitation.
