Assessment of Pulmonary Blood Volume Using Contrast Echocardiography During Exercise
Status: Recruiting
Location: See location...
Study Type: Observational
SUMMARY
The purpose of this study is to evaluate whether pulmonary blood volume (PBV) derived from contrast echocardiography can serve as a non-invasive surrogate for invasive pulmonary artery wedge pressure (PAWP) during exercise. Also, to compare changes in PBV with exercise in patients with and without heart failure and pulmonary vascular disease.

View:
• Patients referred to the cardiac catheterization laboratory for invasive exercise right heart catheterization for evaluating exertional dyspnea. Investigators will include patients with normal or low EF, and across the spectrum of pulmonary hypertension severity.
