A quadricuspid aortic valve (QAV) is a rare congenital aortic valve anomaly. Here we describe a case of a patient with a QAV associated with severe aortic, mitral, and tricuspid regurgitations that were treated surgically. Transesophageal echocardiography clearly demonstrated a QAV. The aortic vlave was excised and replaced with an 18-mm ATS AP360 valve (ATS Medical Inc., Minneapolis, MN), and the mitral valve was replaced with a 29-mm St. Jude valve (St. Jude Medical Inc., St. Paul, MN). Subsequently, tricuspid annuloplasty was performed with a 30-mm MC3 ring (Edwards LifeSciences, Irvine, CA) for annular enlargement. The patient’s postioperative course was uneventful. Despite the widespread use of cardiac echocardiography, some cases of a QAV are incidentally detected during surgery. As a QAV can be associated with other congenital malformations, it is crucial to diagnose a QAV accurately using a combination of available imaging modalities, prior to surgery.
