Transesophageal echocardiography accurately diagnosed a rare quadricuspid aortic valve with an X-shaped diastolic closure and moderate aortic regurgitation in a 63-year-old woman.
Case Report (n=1)
Transesophageal echocardiography is a key tool for the accurate diagnosis and anatomical definition of the rare quadricuspid aortic valve malformation.
Supports TEE for rare valve characterization; hypothesis-generating, needs prospective validation.
The quadricuspid aortic valve (QAV) is a rare malformation; often isolated, sometimes associated with other heart diseases. Before the era of echocardiography, the diagnosis was made incidentally at autopsy or during surgery of valve replacement. The extensive use of echocardiography has allowed an early and accurate diagnosis of this malformation. In many cases, the transthoracic approach is suitable for the diagnosis but, transesophageal echocardiography is a tool for the accurate definition of the valve anatomy. This review analyzes, after the presentation of a clinical case, the current knowledge on embryogenesis, classification, diagnosis and clinical course of QAV.

Savino et al. (2015) conducted a case report in Quadricuspid aortic valve (n=1). Quadricuspid aortic valve was evaluated. Transesophageal echocardiography accurately diagnosed a rare quadricuspid aortic valve with an X-shaped diastolic closure and moderate aortic regurgitation in a 63-year-old woman.
