In the current issue of the Journal, Mastropietro and colleagues1 retrospectively reviewed the results of 216 children who had undergone surgical repair of truncus arteriosus at 15 institutions in the United states between 2009 and 2016. They focused on early outcomes and assessed risk factors associated with major adverse cardiac events (MACE), an outcome variable that combined in-hospital mortality with the requirement for postoperative cardiopulmonary resuscitation or extracorporeal membrane oxygenation support.
