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.

Inclusion Criteria:
- patients will have congenital heart disease or acquired cardiopulmonary disease.
- normal volunteers will be willing to undergo MRI
Exclusion Criteria:
- patients unable to receive intravenous contrast material (this does not apply to
normal volunteers)
- subjects with arrhythmias which will prevent MRI cardiac gating
- subjects with illnesses which make participation inappropriate. In addition, patients
who would normally be excluded from an MRI study because of pacemaker implant,
aneurysm clip, severe claustrophobia, or any other condition which, based on the
Investigator's judgment, would preclude proximity to a strong magnetic field will be
excluded from this study as well.
- NORMAL VOLUNTEERS may be excluded if they are not able to remain still during the
exam or follow the instructions of the investigators.
