The purpose of this study is to determine if non-invasive heart imaging using new investigational computer software and changes in blood flow patterns with exercise can give us information about pulmonary arterial hypertension (PAH). This study will combine the information obtained with a research MRI scan using new investigational computer software, heart echo (ultrasound), and right heart catheterization during exercise. The results may help us understand how heart function changes during exercise in PAH, which may be helpful in the medical management for future patients. The results may also help us understand the mechanisms underlying different types of pulmonary hypertension.
