Personal Characteristics
7-week-old girl
Clinical Characteristics
Presented with an asymptomatic murmur, clinical signs of pulmonary stenosis, right ventricular hypertrophy, stenosis at both valvar and infundibular level, right ventricular systolic pressure of 70 mmhg, overall gradient of 50 mmhg across the right ventricular outflow tract, pulmonary valve thickened and doming during systole, decrease in the intensity of the murmur and the electrocardiogram no longer appeared abnormal by the age of four, right ventricular systolic pressure of 32 mm hg, outflow gradient fallen to 14 mmhg, no audible murmurs at the age of eight, normal heart on cross-sectional echocardiography and doppler ultrasound
Remission Characteristics
Decrease in the intensity of the murmur, electrocardiogram no longer appeared abnormal, right ventricular systolic pressure of 32 mm hg, outflow gradient fallen to 14 mmhg, no audible murmurs at the age of eight, normal heart on cross-sectional echocardiography and doppler ultrasound
Treatment & Mechanisms
Proposed Remission Mechanisms
Not discussed
Clinical Treatment
Treated conservatively
Additional Notes
Pulmonary stenosis diagnosed in infancy usually increases in severity with age or, if it is mild, may remain so for many years. This case reports a child in whom moderately severe pulmonary stenosis in infancy appeared to completely resolve by the age of 8 years.
