Callahan R, et al. - Between January 2000 and December 2016, single center retrospective review was performed to estimates the characteristics of coronary obstructions that underwent transcatheter intervention in a pediatric catheterization laboratory, the procedural details, and patient outcomes. For this analysis, 33 patients underwent 39 transcatheter interventions on 39 lesions, mainly left main coronary and right coronary arteries. Researchers reported that most coronary obstructions intervened upon in a pediatric cath lab were on young, critically ill patients with congenital heart disease secondary to surgical manipulation/injury or thrombosis. In this population, transcatheter intervention should be considered a potential treatment strategy.
