Bridge to Lung Transplant With Trans-septal Extra-corporeal Membrane Oxygenation (ECMO) for Right Heart Failure From Pulmonary Hypertension

This study is examining a specialized life-support technique called trans-septal ECMO (a machine that takes over heart and lung function) as a temporary bridge to keep critically ill patients with severe pulmonary hypertension (dangerously high blood pressure in the lungs) alive while they wait for a lung transplant. **You may be eligible if...** - You are already listed for a lung transplant - You have been diagnosed with pulmonary hypertension (either primary or secondary to lung disease) - Your right heart is failing despite maximum medication support - You are over 18 years old with a BMI under 35 **You may NOT be eligible if...** - You are in the most critical stage of cardiogenic shock (INTERMACS 1) - You have severe liver or kidney failure - You have evidence of acute brain injury - You have active uncontrolled bleeding or a bleeding disorder - You have a serious active infection Talk to your doctor to see if this trial is right for you.
