Full Study Name

Tricuspid Atresia Study (IRB no. 44485)


The purpose of this research registry is to gather information across hospitals in North and South American from patients with tricuspid atresia (an absent right heart valve) who have had the condition since birth. Researchers aim to understand the differences in outcomes of these patients in light of their medical characteristics and treatment. To this end, medical records will be reviewed, and participants will be asked to complete questionnaires about medications, exercise limitations, surgeries or procedures and overall quality of life.
