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

Mayo Clinic

Information provided by (Responsible Party):

Ian May

Brief Summary:

The purpose of this study is to determine if transseptal extra-corporeal membrane oxygenation (ECMO) can bridge pulmonary hypertension- right heart failure (PH-RVF) patients to lung transplant safely.

Condition or disease

Lung Transplant

Pulmonary Hypertension

Intervention/treatment

Protek Solo Transseptal Cannula

Phase

PHASE1

Detailed Description:

Results will be released as a manuscript once it has gone through the peer review process. Results will be released even in the event of negative outcomes and the release will be hastened if the study is terminated early. Medicare beneficiaries may be affected by the device under investigation if they are candidates for lung transplant. Since this is such a select group of patients, we do not expect the results of this trial to be generalizable to the general Medicare population.
