Derivations cavopulmonaires: a propos de 40 observations

Fourty patients with univentricular heart, underwent a cavopulmonary shunt procedure. The majority have an excellent hemodynamic status with ventricular end diastolic pressure >12 mmHg and a mean pulmonary artery pressure >15 mmHg. However, 11 patients have ventricular dysfunction, 9 have an incompetent systemic atrioventricular valve and 6 have mean pulmonary artery pressure >15 mmHg. The pulmonary arteries were of a good size in all cases with a Nakata index >100 mm2/m2. Cavopulmonary connections are satisfactory palliative procedures in the treatment of univentricular cardiac disease
