U.S., Oct. 24 -- ClinicalTrials.gov registry received information related to the study (NCT07220226) titled 'Venous Compression in Fontan' on Sept. 25.
Brief Summary: The aim of this study is to investigate whether venous compression garments increase exercise stroke volume in patients with Fontan circulation. To address this aim, we will test the following hypotheses:
1. Acute and chronic external venous compression will increase exercise stroke volume in patients with Fontan circulation.
2. Patients with significant venous varicosities will have a greater response to venous compression.
Participants will:
* Undergo submaximal exercise testing in MRI to measure venous return and exercise stroke volume with and without the wearing of c...
