Cardiac Surgery Research

Research within the Division of Cardiac Surgery at Tufts Medical Center has had a long and productive history.


Currently we have ongoing projects that include basic scientific investigation, as well as clinical research and participation in large scale clinical trials.

Current research

Current research projects include:
