The clinical findings and treatment options of cardiovascular abnormalities in a 20-year old male patient with Noonan syndrome are described with literature review. The classical clinical features of Noonan syndrome which were identified included short stature, abnormalities of ear and eye, low posterior hair line, cubitus valgus and webbed neck. The major cardiovascular abnormalities included pulmonary valvular stenosis and hypertrophic cardiomyopathy. A comparison with Leopard syndrome is made and the overlapping features between the two rare genetic disorders are discussed.
