Late-Breaking Clinical Trials are typically first-time international or US presentations of the primary endpoint or important secondary endpoint results of prospective, randomized clinical trials or of large-scale, impactful single-center or multicenter registries.

Late-Breaking Clinical Science submissions are the first worldwide presentations of smaller randomized trials,   impactful single-center or multicenter registries, or first-in-man experiences with novel devices or drugs. Accepted submissions will be presented in the Main Arena at TCT 2019, and during press conferences scheduled on the same days as the Main Arena presentations.

The following rarely qualify as Late-Breaking Clinical Trial submissions: preclinical studies, early first-in-human device studies, and meta-analyses; these should be submitted as Abstracts or as Interventional Innovations.
