  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Lack of in-vivo testing of cell product. While there are several different approaches to measure myocardial strain (myocardial tagging, DENSE, etc.), these were not employed in this study due to the need for specialized expertise at each site.
