The commonest cause for Tricuspid Regurgitation
is NOT in the valve itself.
It is usually secondary to Pulmonary valve
or Pulmonary artery
pressure rise - which itself may be from left heart problems.
No treatment directed at the regurgitation is generally needed.
If the cause is found and treatable, this will resolve without any primary procedure at it.
You need to follow the pressure / Follow up with Paediatric Cardiologist (Heart Specialist for Children)
Good Luck / All the best
