Because a normal ear canal and pinna are required, TransEar is usually not indicated for these conditions.

A tricuspid atresia is a defect where a solid sheet of tissue forms instead of the tricuspid valve. The tricuspid valve is between the right atrium (the upper chamber) and right ventricle (the lower chamber) of the heart. Without the tricuspid valve, oxygen-poor or blue blood entering the right atrium cannot travel normally to the lungs to pick up oxygen.

Pulmonary valve atresia is a defect where a solid sheet of tissue forms instead of the pulmonary valve. This prevents oxygen-poor blood in the right side of the heart from traveling normally to the lungs to pick up oxygen.
