-
Impact of ambient air vs nasal liquid oxygen on exercise performance in pulmonary vascular disease
This study tests whether using nasal liquid oxygen during a 6-minute walk test changes how far patients with PAH or CTEPH can walk compared to breathing room air.
-
Liquid oxygen vs ambient air during a 6-minute walk in people with pulmonary vascular disease
This study tests whether walking with liquid oxygen at about 4 L/min helps or hinders distance walked compared with walking on room air in adults with PAH or CTEPH living in Switzerland.
-
Pulmonary Vascular Disease in Valvular Heart Disease: How Valve Procedures Affect Blood Flow
This study tests how blood flow in the lungs changes in adults with left-sided valve disease who are having valve surgery and looks to see if patterns can predict reversibility of tricuspid regurgitation and right heart dysfunction.
-
Using contrast echocardiography during exercise to assess pulmonary blood volume
This study is testing if a special heart ultrasound can safely measure blood volume in the lungs during exercise to help understand how it affects people with and without heart failure.
-
Comparing pulmonary hypertension in patients with left heart disease
This study is trying to understand how pulmonary hypertension affects patients with heart disease by looking at different tests and measurements to see how their condition varies.
-
Registry for children with pulmonary hypertension
This study is collecting information about children with pulmonary hypertension to better understand the condition and improve treatment options for them.
