title: Two cases of quadricuspid aortic valve: preoperative diagnosis and surgical treatment.
abstract: Two cases of severe aortic regurgitation were treated surgically. Both patients had a quadricuspid aortic valve, which was diagnosed preoperatively by aortography and/or transesophageal echocardiography (TEE). In the first patient, both aortic and mitral valve replacement were performed with an ATS prosthetic valve. In the second patient, only aortic valve replacement was performed. The postoperative course was uneventful in both cases. Quadricuspid aortic valve is relatively rare. We discuss the preoperative diagnosis of quadricuspid aortic valve, as well as reviewing the relevant literature.
