Key result
Congenital pulmonary valve insufficiency commonly occurs with ventricular septal defects and a continuous precordial murmur, though it may also present as an isolated cardiac malformation.
Highlights the clinical presentation and common associations of congenital pulmonary valve insufficiency.

May support inclusion of congenital pulmonary valve insufficiency in continuous murmur differentials; leaves open need for prospective natural history data.
Congenital insufficiency of the pulmonary valve may result if the valvular cusps develop faultily or fail to develop. It is commonly associated with ventricular septal defect, with or without pulmonary stenosis. Under these conditions a continuous precordial murmur may be present. Less commonly, congenital pulmonary valvular insufficiency may appear as an isolated cardiac malformation.
