Recently a case with both aortic and pulmonic subvalvular stenoses was studied in which no other associated lesions were present, and the diagnosis was made before operation by cardiac catheterization. We are unaware of any previously reported cases of a similar nature. Surgical correction of both lesions was successful, utilizing temporary cardiopulmonary bypass.

Report of Case  A 19-year-old white youth was admitted to St. Luke's Episcopal Hospital on Dec. 10, 1956, for cardiac studies. A cardiac murmur was first noted during an attack of pneumonia during infancy. He developed more slowly than normal and was considerably smaller than his siblings; at age 12 years he weighed 68 lb. Typical anginal pains on exertion appeared during his high school years, and since
