Cardiac Resynchronization Therapy in Adult Congenital Heart Disease With Systemic Right Ventricle: RIGHT-CRT

This study will be the first to bring evidence on CRT efficacy in ACHD patients with heart failure and SRV. If results are positives, CRT may improve functional capacities and quality of life of patients and will become an option of choice in this population. If results are negatives, futile CRT implantation may be avoided in this population in particular considering potential adverse effects and CRT-related complications. Double blind randomized cross-over trial. 40 patients will be enroled. Their follow-up will be 6 months.
