Our patient under discussion has a type A QAV based on the Hurwitz and Roberts classification (4 equal-sized cusps) and type 1 QAV based on the Nakamura classification (supernumerary valve between the left coronary and right coronary cusps). The aortic valve has 2 raphes, which are fused tangentially between the right and noncoronary cusps and between the left and supernumerary cusps, leading to the valve being functionally bicuspid. Transthoracic echocardiography is useful in identifying a QAV.
