Coronary microcatheters (MCs) are often used in complex and chronic total occlusion (CTO) percutaneous coronary intervention (PCI)1,2 to facilitate guidewire manipulation and exchanges, and enhance their penetration force. Coronary MCs can be classified as high profile, low profile, angulated, dual lumen, and plaque-modifying1. Despite extensive clinical use, the failure modes of these devices have not been systematically studied. We queried the “Manufacturer and User Facility Device Experience” (MAUDE) database for reports on the most commonly used coronary MCs to understand their failure modes better.


The MAUDE is an online database created by the ...
