A recent investigation by KFF Health News has raised significant concerns regarding the safety and efficacy of the mitraclip, a medical device approved by the FDA in 2013 to treat mitral regurgitation, a condition that can lead to heart failure and death. The mitraclip is designed to repair leaky heart valves in patients who are often too ill for traditional surgery, but the investigation reveals a troubling history of malfunctions and adverse events associated with the device.
Since its approval, the mitraclip has been linked to over 17,000 reports of malfunctions, including more than 1,100 fatalities. Critics argue that the data supporting the device's safety and effectiveness has been questionable, with one FDA advisor famously likening the research to \"horse poop and dog poop.\" The FDA's reliance on manufacturer-submitted reports for post-market surveillance has come under scrutiny, as these reports do not definitively establish causality between the device and reported deaths.
Abbott, the manufacturer of mitraclip, maintains that the device is a safe and effective treatment, citing a robust foundation of clinical evidence from over 20 trials. However, the investigation highlights a potential conflict of interest, as the very companies responsible for proving their products' safety often fund the clinical trials themselves. This raises questions about the integrity of the research and the FDA's approval process, which has seen products approved despite objections from its own staff.
The FDA's initial concerns about the clinical data presented by Abbott included allegations of biased testing conditions, where patients treated with mitraclip were operated on by more experienced surgeons compared to those in the control group. Despite a split vote from an advisory committee regarding the device's effectiveness, the FDA ultimately approved it for a narrower patient population than initially proposed.
This investigation serves as a cautionary tale about the intersection of medical device regulation, corporate interests, and patient safety, highlighting the need for greater scrutiny and transparency in the approval process.
