The pulmonary valve normally consists of 3 leaflets supported in a semilunar fashion within the sinuses of the pulmonary trunk. Pulmonary leaflet malformations, such as congenital single pulmonary cusp absence, bicuspid pulmonary valve, and quadricuspid pulmonary valve anomalies, as well as pulmonary valve commissural fusion, are seldom identified preoperatively on echocardiography. In this study, we report on 5 children with different types of pulmonary valve malformations diagnosed by transthoracic echocardiography.
Keywords: bicuspid pulmonary valve; pulmonary regurgitation; pulmonary stenosis; quadricuspid pulmonary valve; transthoracic echocardiography.
