Effects of Negative Pressure Ventilation Onto Hemodynamics and Right Ventricular Funktion in Patients After Implantation of a Left Ventricular Assist Device.

This study tests whether a non-invasive breathing support device called a cuirass ventilator (a shell that fits over the chest) can help the heart and right ventricle function better after a patient receives a left ventricular assist device (LVAD) — a mechanical pump implanted to help a failing heart pump blood. **You may be eligible if...** - You have recently had a durable left ventricular assist device (LVAD) implanted **You may NOT be eligible if...** - You had complications during your LVAD surgery (such as major bleeding or emergency complications) - The cuirass breathing device doesn't physically fit you - A study investigator is unavailable - Your circulation or breathing is currently unstable Talk to your doctor to see if this trial is right for you.
