Summary: Quadricuspid aortic valves (QAV) are a rare but well recognized cause of significant aortic regurgitation. The first case was found reported in 1862. Since then there have been 110 reported cases of QAV and we report 4 more. Pre- viously, these were diagnosed at the time of surgery or post- mortem examination.

25 Jul 2016 INTRODUCTION. Quadricuspid aortic valve (QAV) is a rare congenital heart disease with an incidence of 0.00028-0.00033% in autopsy series[1], 0.0059-0.0065% for patients undergoing transthoracic echocardiographic examinations[2] and 0.05-1% for those receiving aortic valve replacements for aortic
Abstract. Quadricuspid aortic valve is a rare congenital heart defect usually detected by echocardiography or at the time of aortic valve surgery. Preoperative recognition of this abnormality has clinical significance because it is frequently associated with other congenital cardiac abnormalities and anomalies of coronary
Quadricuspid aortic valve (QAV) is rare congenital malformation of the aortic valve with estimated prevalence of 0.013% to 0.043% [1-4]. QAV is most commonly associated with aortic insuf iciency (AI), which is found in almost 75% of cases [5]. QAV can also be associated with other cardiac defects such as ventricular or

cusp, a triangular resection followed by commisuroplasty was chosen. One patient had a conjoint large cusp, and the remaining 2 cusps were very small, so a plication of the conjoint cusp was performed; the commisure between the remaining cusps was closed, resulting in bicuspidization of the QAV.
