Medtronic has issued a voluntarily global recall of unused Medtronic Valiant Navion thoracic stent graft systems and informed physicians to immediately cease use of the device until further notice, according to a company advisory.
“In accordance with its commitment to patient safety — and in consultation with independent physicians — Medtronic initiated this action in response to information recently obtained from the Valiant Evo Global Clinical Trial indicating that three patients in the Valiant Evo Global Clinical Trial were observed to have stent fractures, two of which have confirmed type IIIb endoleaks. One patient death was reported,” Medtronic reported in a press release.
According to the company, an independent imaging laboratory reviewed all available images from patients enrolled in the Valiant Evo Global Clinical Trial and found 7-of-87 patients were observed to have stent ring enlargement beyond the design specification. Those observations require further assessment to determine potential clinical importance, the company said.
Medtronic is currently conducting a comprehensive technical root cause investigation, including further review of follow-up clinical trial imaging and commercial complaints and imaging.
“There is nothing more important than the safety and well-being of patients,” said Nina Goodheart, senior vice president and president, Structural Heart & Aortic, which is reported as part of the Cardiac Vascular Group at Medtronic. “We treat matters of product safety with the highest priority and urgency. Our decision to implement this voluntary recall is necessary to ensure the utmost patient safety. As our investigation continues, we are committed to timely communication with physicians and regulatory bodies.”
Medtronic has contacted the US FDA, along with other regulatory bodies around the world, to share information related to this issue. Medtronic will continue working directly with regulatory authorities on this global voluntary recall.
