Abstract

OBJECTIVE: The MitraClip (Abbott) is a commercially available device to perform percutaneous transcatheter mitral valve repair (TMVR) for patients with symptomatic mitral regurgitation (MR). Recent data support its role in appropriately selected patients with functional MR, and its use is poised to increase. However, limited safety data in "real-world" practice are available after market introduction. METHODS: We queried all available adverse event reports from the publicly available Manufacturer and User Facility Device Experience (MAUDE) database including "injuries" and "deaths" from October 2013 (date of Food and Drug Administration [FDA] premarket approval) to September 2017 using the following search limits: brand name ("MitraClip") and product code ("NKM," a unique FDA designation linked to MitraClip). RESULTS: During the first 4 years after FDA approval, MAUDE received 200 death reports and 1666 injury reports containing 2974 unique adverse events. Of all death reports, 21% described deaths occurring >1 year post MitraClip and 30% included limited details. The top three known causes of death included complications requiring rescue high-risk surgery, clip detachment or unsuccessful clip placement, and damage to the valvular apparatus. Similar non-fatal events were reported. Additional procedures or surgical intervention were required in 227 injury events (8%). CONCLUSIONS: While injuries reported to the FDA have steadily increased with more widespread use of TMVR, device- or procedure-related death reports have accrued more slowly, corroborating a potential institutional or operator learning curve with this device. However, in light of incomplete and poor data quality, higher-fidelity systems of postmarketing safety surveillance are needed in the evaluation of emerging devices.
