[Patient with tricuspid atresia undergoing orthopedic surgery: anesthetic considerations].

We describe a 52-year-old patient with rheumatoid arthritis, interventricular communication and pulmonary stenosis. After an accidental fall she was scheduled for total hip replacement. The main objective of anesthetic management was to preserve pulmonary blood circulation at arterial pressures that would assure adequate tissue perfusion. Other objectives were to maintain hydration to prevent decreases in hematocrit levels, avoid systemic embolization and allow for antibiotic prophylaxis.
