Surgical aortic valve replacement reveals a rare late-presenting unicuspid aortic valve in a 62-year-old woman.
Case Report (n=1)
This case highlights the rare late presentation of a unicuspid aortic valve in a 62-year-old female, which was initially suspected to be a bicuspid valve on echocardiography.
TEE may misclassify unicuspid aortic valve as bicuspid; leaves open need for refined imaging criteria before valve surgery.
We describe the case of a 62-year-old female presenting with new onset progressive dyspnea on exertion and a new diagnosis of aortic stenosis. Transesophageal echocardiography showed fusion of the aortic valve leaflets suspicious for bicuspid aortic valve with dilated ascending aorta. Surgical replacement of the valve revealed a unicuspid aortic valve with one true commissure at the level of the left and noncoronary cusps. The case is supported by clinical, echocardiographic and angiographic imaging and discussion of current imaging modalities used in diagnosis of aortic valve pathology.

Chester et al. (2015) conducted a case report in Unicuspid aortic valve with aortic stenosis (n=1). Surgical replacement of the aortic valve was evaluated on Diagnosis of unicuspid aortic valve. Surgical replacement of the aortic valve in a 62-year-old female with suspected bicuspid aortic valve revealed a rare late-presenting unicuspid aortic valve.
