Feasibility Trial for a Right Ventricular Failure Platform Trial

This feasibility study looks at whether a standardized clinical trial platform can be built to test new treatments for right ventricular failure (RVF) — a serious condition where the right side of the heart becomes too weak to pump blood efficiently to the lungs. It tests whether patients with RVF can be enrolled in trials and tracked safely. **You may be eligible if:** - You are 18 or older with a history of right heart dysfunction or failure caused by pulmonary arterial hypertension, left heart disease, lung disease, or chronic blood clots in the lungs - You have symptoms affecting your daily life (NYHA class II-IV, meaning mild to severe functional limitation) - You have evidence of right heart dysfunction on recent blood tests and echocardiogram (within 3 months) **You may NOT be eligible if:** - You are unable to provide informed consent - You cannot comply with study procedures - You are in a clinical situation that makes participation unsafe Talk to your doctor to see if this trial is right for you.
