RESUMO
It has been controversial how to manage severe dysfunction of the systemic right ventricle and severe tricuspid regurgitation for adult patients with congenitally corrected transposition of the great arteries. We reported a 43-year-old man with these disorders, who received pulmonary artery banding and cardiac resynchronization therapy without cardiopulmonary bypass. The degree of the tricuspid regurgitation was improved to mild-moderate and systemic right ventricular ejection fraction was improved from 28 to 45% after surgery. Cardiopulmonary exercise testing showed that the predictive value of anaerobic threshold and peak oxygen uptake improved from 65 to 99% and 59 to 92%, respectively. In conclusion, pulmonary artery banding and cardiac resynchronization therapy can be the first choice of surgery for severe tricuspid regurgitation with severely impaired systemic right ventricular function. After improving systemic right ventricular dysfunction tricuspid surgery could be the next choice as a surgical intervention in the future.
