Conzelmann and colleagues aimed to gain information about outcomes of transcatheter aortic valve replacement (TAVR) procedures in patients with coronary heights less than 7 mm. These procedures are not common, as one of the contraindications for TAVR is a low coronary height. Among more than 3,000 TAVR patients from the Karlsruhe registry, 86 had an average coronary height of 6.4 mm. Within 30 days, there were four cardiac deaths, three noncardiac deaths, and three coronary obstructions in this patient group. The authors concluded that coronary-related complications in TAVR with coronary heights less than 7 mm occurred infrequently, however they were serious when they occurred.
