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.
|Condition or disease||Intervention/treatment||Phase|
|Univentricular Heart Children, Adult||Procedure: polysomnography||Not Applicable|
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.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||50 participants|
|Intervention Model:||Single Group Assignment|
|Intervention Model Description:||all participants receive the same intervention throughout the protocol|
|Masking:||None (Open Label)|
|Official Title:||Can Ventilatory Response at Rest Predict Ventilatory Efficacy and Exercise Tolerance in Patients With a Univentricular Congenital Heart Disease?|

Patients with univentricular congenital heart disease
Patients 8 years old or more with functionally univentricular congenital heart disease
Sleep examination strictly non-invasive with skin sensors. This exploration would allow for the detection of respiratory sleep disorders and consider of appropriate management for patients.
- Pearson correlation - The measure the respiratory drive to hypercapnia with P0.1 during the rebreathing technique at rest [ Time Frame: day 90 after inclusion visit (visit 2) ]
between the measure the respiratory drive to hypercapnia with P0.1 during the rebreathing technique at rest
- between VE/VCO2 slope during a cardiopulmonary exercise
- Pearson correlation [ Time Frame: day 90 after inclusion visit (visit 2) ]
- between the measure of the respiratory drive to hypercapnia with P0.1, the rebreathing technique at rest and Central apnea index scored with a polysomnography during a night
- between the measure of the respiratory drive to hypercapnia with P0.1, the rebreathing technique at rest and NYHA, New York Heart Association Functional Classification
- between the measure of the respiratory drive to hypercapnia with P0.1, the rebreathing technique at rest and the quality of life evaluated by questionary
- between the measure of the respiratory drive to hypercapnia with P0.1, the rebreathing technique at rest and data of cardiac echography
