Question special
Expert

In studies such as this, a question arises. Is this something that can be done in a specialized center with these select clinicians who have an infrastructure and technical experitse that cannot be reproduced elsewhere, or can this be replicated to the same degree of precision elsewhere? In several cases in the past, when the efficacy and safety of highly technical procedures are compared outside of the founding centers or in major heart centers, the benefits are not as robust and the risks are higher.
