Modes of failure of guide catheter extensions: Insights from the MAUDE database.

OBJECTIVES

Guide catheter extensions (GCEs) are commonly used to facilitate percutaneous coronary interventions (PCIs). We investigated the incidence and modes of failure of GCEs..

METHODS

Data from the Manufacturer and User Facility Device Experience (MAUDE) database between 2012 and 2022 were used to investigate the most common modes of failure and related adverse events with the use of GCEs. We performed analysis of 4 commonly used catheters: GuideLiner (Teleflex), Guidezilla (Boston Scientific), TrapLiner (Teleflex), and Telescope (Medtronic). The first event reported for GuideLiner was in 2012, Guidezilla in 2018, TrapLiner in 2017, and Telescope in 2019.

RESULTS

During the study period, a total of 651 events were reported to the database. A total of 429 true GCE device failures were identified: 59 (14%) for GuideLiner, 297 (69%) for Guidezilla, 47 (11%) TrapLiner, and 26 (6%) for Telescope. Catheter detachment or fracture was the most frequently reported device failure for all 4 GCEs; these failures included shaft fractures, tip deformations, and collar detachments. We identified 222 reported events as unspecified adverse events; these events included device-to-device incompatibility, difficulty to advance, and device fractures outside the patient body. Only 58 (8.9%) events resulted in patient complication. Of these, coronary artery dissection was the most frequently reported complication.

CONCLUSIONS

Device detachment/fracture is the most common mode of device failure in all 4 GCEs, and coronary dissection is the most common patient complication.
