The program provides exposure to many multi center research trials and investigator initiated trials. Additionally, the fellows may obtain hands on experience in the cardiac catheterization lab with aggressive percutaneous mechanical circulatory support including Impella, Protek Duo, left heart catheterization, IVUS, and ECMO. This would be in addition to the standard requirements of right heart caths, endomyocardial biopsy and Cardiomems.
