- There is a great vessel in heart known as “pulmonary artery” which supplies blood to both lungs. Pulmonary artery has a valve.
- When there is an obstruction at the level of valve, it is known as valvular pulmonary stenosis.
- Valvular pulmonary stenosis can occur either as an independent lesion or can be associated with other cardiac diseases like TOF.
- Child can be presented in various forms depending on age of the child and severity of the obstruction.
- Newborn babies if symptomatic are having severe or critical obstruction in pulmonary valve and presented as a shock lesion with low blood supply to body parts.
- In children, if PS is mild, then children are asymptomatic and illness is detected on routine examination by a pediatrician by hearing an abnormal heart sound in the form of murmur on examination.
- As severity of obstruction increases, child presents with early fatigue, decrease exercise tolerance, syncope, shortness of breath rarely sudden cardiac death.
For diagnosing pulmonary stenosis, “echocardiogram” needs to be done.
Dr Gaurav Agrawal is a Pediatric Cardiologist (Child and Fetal heart Specialist). Dr Agrawal is a pediatrician who has specialized training in the treatment of various child heart related problems (neonates to 18 years of age). He is also having a vast experience in fetal echocardiography.
He is one of the very few pediatricians in India who practices pediatric cardiology exclusively. Cardiac problems in children are common in children, sometimes life threating and often not diagnosed properly. Early diagnosis and timely treatment is very important. Areas of specific interest include child echocardiography including fetal echocardiography, diagnostic and therapeutic cardiac catheterization (pediatric cardiac holes closure by device, opening of obstructed cardiac valves by balloons etc).
