Goal 2: Reduce Human Disease

Heart transplant surveillance

It is essential to develop clinically viable, non-invasive, less expensive technologies for the surveillance of allograft rejection in heart transplant patients. Critical challenges that exist in the near term or long term surveillance after transplant is the unavailability of molecular and cellular level markers that can be non-invasively imaged and quantified detect rejection and thus improve patient survival. Development of molecular and cellular level imaging techniques is essential to address this critical question.

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? Critical Challenge (CC)

Details on the impact of addressing this CQ or CC

Development of methods for near term or long term surveillance after transplant can help detect the rejection and thus improve patient survival

Feasibility and challenges of addressing this CQ or CC

The fast growth in the imaging technologies and molecular and cellular imaging technologies are gaining foot in cardiovascular sciences and should be feasible within a decade
The current surveillance to detect transplant rejection requires repeated testing with endo myocardial biopsy and catheter angiography. Both technologies are highly invasive and very expensive. Post-transplant surveillance is focused on the cellular rejection in the near term after transplant and cardiac allograft vasculopathy in the long term.
