Voluntary recall of Medtronic 23mm Engager™ Transcatheter Aortic Bioprosthesis

Medtronic 3F Therapeutics, Inc would like to inform healthcare professionals of a voluntary recall of Medtronic 23mm Engager™ Transcatheter Aortic Bioprosthesis. A review of the 2-year follow-up data of Engager European Pivotal Trial has shown that 16 of 32 subjects implanted with a 23mm device have a mean gradient of ≥20 mmHg at some point after the implant (average mean gradient at 2-year follow up: 22.0 ± 7.5 mmHg). Gradient is a measure of the resistance to flow through the valve. A mean gradient of 20-40 mmHg is associated with mild stenosis (narrowing of the valve) per the Valve Academic Research Consortium (VARC) -2 guideline. As part of patient management, healthcare professionals are recommended to conduct transthoracic echo in symptomatic patients implanted with the device to assess valve hemodynamics . Please refer to the letter for details.
