Regression of valvular pulmonary stenosis.

Eight patients with mild to moderate valvular pulmonary stenosis underwent serial physiological studies before surgical intervention. Average pulmonary valve area at the initial study was 0.59 cm.2 and at the second study (average 7.8 years later) was 1.09 cm.2, resulting in an average increase of 0.49 cm.2 (p greater than 0.05). In normal subjects during… (More)
