Background:Congenital heart diseases occur in around 1% of the liveborn. Trilogy of Fallot is a rare congenital heart disease comprising of pulmonary valve stenosis, atrial septal defect, and right ventricular hypertrophy.

Case:We describe a patient who has incidental findings of pansystolic murmur during physical examination and was ultimately diagnosed with severe pulmonary stenosis with large atrial septal defect on transthoracic echocardiography. Possible management plan was discussed with patient including combined percutaneous atrial septal defect occlusion and pulmonary balloon valvuloplasty in treating Trilogy of Fallot.

Conclusion:Although the Trilogy of Fallot is a rare congenital heart disease, we need to be vigilant to identify this combination as the early treatment with percutaneous transcatheter or surgical correction can prevent long term deleteriously complications.
