Twenty-five patients with tricuspid atresia, ranging in age between 2 months and 23 years, previously morphologically studied, were assessed by M-mode echocardiography with regard to left ventricular function. Fifteen of them underwent palliative cardiac surgery (systemic-pulmonary anastomosis). Thirty normal subjects, same age and sex, were selected as controls. Patients with tricuspid atresia had a significant increase of left ventricular dimensions and mass and significant decrease of shortening fraction and ejection fraction. The left ventricular pre-ejection/ejection ratio (LPEP/LVET) was significantly higher in patients with tricuspid atresia compared to normals. In patients without surgical shunt there was no significant correlation between Qp/Qs determined by oximetry and the end-diastolic dimension and left ventricular function parameters. In patients with surgical shunt a significant correlation was found between ejection fraction, shortening fraction, systolic time intervals and Qp/Qs. Qp/Qs significantly correlated with end-diastolic dimension. Shortening fraction and ejection fraction were higher in patients with satisfactory systemic saturation, while left ventricular mass was increased in patients with long-standing surgical shunt. These data suggest that patients with tricuspid atresia, with or without surgical shunt, may present with a decreased left ventricular function, detected early by echocardiography.
