Key result
Patients with tricuspid atresia had a significantly depressed left ventricular ejection fraction compared to controls, particularly those with a surgical shunt or pulmonary artery banding.
Why the study?
Is left ventricular ejection fraction depressed in patients with tricuspid atresia as measured by equilibrium gated radionuclide angiography compared to controls?
Population
16 patients (15 with tricuspid atresia, 1 with tricuspid stenosis) and 16 control patients
Comparison
Equilibrium gated radionuclide angiography vs Control group of 16 patients
Design
Case-control

Reduced LVEF in tricuspid atresia may support monitoring, especially post-shunt or banding; leaves open prospective validation and outcome impact.

Is left ventricular ejection fraction depressed in patients with tricuspid atresia as measured by equilibrium gated radionuclide angiography compared to controls?
Equilibrium gated radionuclide angiography is a viable non-invasive method to identify depressed left ventricular ejection fraction in patients with tricuspid atresia.
Baker et al. (1984) conducted a case-control in Tricuspid atresia (n=32). Tricuspid atresia vs. Control group was evaluated on Left ventricular ejection fraction. Patients with tricuspid atresia had a significantly depressed left ventricular ejection fraction compared to controls, particularly those with a surgical shunt or pulmonary artery banding.
