In a 45 year old patient with clinic diagnosis of aortic regurgitation the two-dimensional echocardiography demonstrated a quadricuspid aortic valve and severe aortic regurgitation by Doppler. The quadricuspid aortic valve is a rare pathology, usually not associated with other cardiovascular pathologies and in which there is evolution with aortic regurgitation due to malposition of the four cusps.
在一名临床诊断为主动脉瓣关闭不全的45岁患者中，二维超声心动图显示为四叶式主动脉瓣，多普勒检查提示严重主动脉瓣关闭不全。四叶式主动脉瓣是一种罕见的病理情况，通常不伴有其他心血管疾病，并且由于四个瓣叶位置异常会导致主动脉瓣关闭不全逐渐加重。
