A 55-year-old woman seeks medical attention with palpitations, atypical chest pain and dyspnea upon exertion, lasting for 12 months. ECG showed left ventricular hypertrophy. Transthoracic Doppler echocardiogram confirmed hypertrophy of the left chambers and showed a quadricuspid aortic valve, with equal-sized cusps, in addition to a moderate regurgitant central flow. Upon echocardiography, the quadricuspid valve is identified by its characteristic "X" form during diastole and rectangular aspect during systole. Heart failure symptoms are presumably caused by valve insufficiency due to abnormal leaflet coaptation. Considering the possibility of progressive regurgitation, follow up on the patient was performed with periodic echocardiographic control. Symptoms responded to treatment.
一名55岁女性因心悸、非典型胸痛和劳力性呼吸困难前来就医，症状持续12个月。心电图显示左心室肥厚。经胸多普勒超声心动图证实左心腔肥厚，并显示一个四叶式主动脉瓣，瓣叶大小相等，此外还有中度中心反流。在超声心动图检查中，四叶式瓣膜在舒张期呈特征性的“X”形，收缩期呈矩形。心力衰竭症状可能是由于瓣叶异常对合导致瓣膜关闭不全引起的。考虑到进行性反流的可能性，对该患者进行了定期超声心动图监测随访。症状对治疗有反应。
