MRI and Computational Simulation Cardiology Study

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.
