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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
