Pulmonary Hypertension Clinical Trial
Official title:
MR Imaging and Computational Simulation of Cardiovascular Physiology Including Velocity, Pressure, and Wall Shear Stress
The purpose of this study is to (1) quantify cardiovascular anatomy and physiology using magnetic resonance imaging under both resting and exercise conditions in patients who have congenital heart disease and in age-matched normal volunteers, (2) use computer models to reproduce and simulate blood flow in these patients, and then (3) to combine the imaging data and computer models to estimate values which cannot be directly measured and to predict physiological changes induced by exercise and medical or surgical therapies.
Investigators hope to gain a greater understanding of the hemodynamics of congenital heart disease and their associated operations as they pertain to real-life situations (i.e. upright and non-sedentary, rest and exercise). With this knowledge, investigators would look to optimize the geometry and physiology of the patients, potentially reducing several of the long-term complications found in congenital heart disease patients such as cardiomyopathy, pulmonary hypertension, arrhythmias, thrombosis and heart failure. ;
