Enhanced External Counterpulsation in Patients With Fontan Circulation

Status Completed

Clinical Trial Summary

The purpose of the proposed study is to determine the safety of enhanced external counterpulsation (EECP), a system for compressing the blood vessels in the legs in synchrony with an individual's cardiac rhythm, in clinically well, adult Fontan patients, to document the acute hemodynamic and myocardial effects of EECP on the Fontan circulation, and to demonstrate acute changes in endothelial function after one hour of the procedure.

Clinical Trial Description

The investigators plan to study the effects of enhanced external counterpulsation (EECP), on patients who have had Fontan surgery for treatment of complex congenital heart disease. Eligible patient volunteers will undergo a series of biophysical measurements at rest including echocardiographic assessment of ventricular function, pulmonary blood flow/cardiac output measurement using an inert gas rebreathing method (Innocor), and measurements of biomarkers of endothelial function (ET-1, NOx). Patients will then undergo 1 hour of treatment with EECP, during which additional echocardiographic assessment of ventricular function and pulmonary blood flow/cardiac output measurements will be performed at multiple levels of leg compression. Subjects will be assessed periodically for adverse effects and discomfort during the EECP treatment. At the completion of treatment, patients will be allowed 30 minutes to rest before undergoing one more echocardiographic assessment of ventricular function, pulmonary blood flow/cardiac output measurement, and measurements of biomarkers of endothelial function (ET-1, NOx). Measurements made during and after treatment will be compared to baseline measurements. ;
