Dear Mr Rajesh Kumar,
For your child's PDA of 4mm, treatment options typically include medication or closure procedures such as catheter-based closure or surgery, depending on the specific condition and your child's health status. It's crucial to consult with a paediatric cardiologist to determine the most suitable treatment approach.
Regarding treatment under Ayushman Bharat (PMJAY) card, you can find registered hospitals and their specialties by visiting PMJAY Hospitals Portal. This portal allows you to search for hospitals based on your location and treatment requirements, making it easier to access healthcare services under the PMJAY scheme.
