Clinical Trial Summary

The aim is to evaluate the correlation between the respiratory control to hypercapnia at rest and the VE/VCO2 slope measured during cardiopulmonary exercise testing.

The hypothesis is that patient with univentricular congenital heart disease have a increasing of respiratory drive like chronic heart failure. This increasing of respiratory drive could participate in the increasing of VE/VCO2 slope measured during cardiopulmonary exercise testing and in the genese of central apnea index during the sleep.

Description:

The patients with univentricular congenital heart disease will perform :

• a cardiopulmonary exercise testing with measure VE/VCO2 slope,

• a measure of the respiratory drive to hypercapnia with occlusion pressure during the rebreathing with at rest (P0,1/PetCO2).

• A polysomnography with a scoring of central apnea index. Correlation will be evaluate between P 0,1/PetCO2 with VE/VCO2 slope and between P0,1/PetCO2 central apnea index.
