Medtronic has announced US Food and Drug Administration (FDA) approval of an early feasibility study (EFS) of the Intrepid transcatheter tricuspid valve replacement (TTVR) system in patients with severe, symptomatic tricuspid regurgitation. This comes on the heels of a recent Breakthrough Device Designation for the Intrepid TTVR System. The Intrepid TTVR system is an investigational device worldwide.
“We’re beginning a new journey that we believe will open the door for the potential future treatment of patients with tricuspid valve regurgitation, who constitute a significant, patient population suffering from heart valve disease today,” said Azeem Latib, section head of interventional cardiology and medical director of structural heart interventions at Montefiore Medical Center in New York, USA and co-principal investigator in the study. “There has been much progress regarding transcatheter replacement of diseased aortic valves, but whether we can replace the tricuspid valve without open heart surgery represents a new frontier in cardiology.”
Representing a large, unmet clinical need, tricuspid regurgitation affects more than 2 million patients in the USA. It is a highly undertreated disease due to the morbidity and mortality associated with surgical intervention.
Medtronic recently received Breakthrough Device Designation by the FDA for the Intrepid TTVR system. The FDA Breakthrough Device Program is intended to help patients receive more timely access to certain technologies that have the potential to provide more effective treatment or diagnosis for life-threatening or irreversibly debilitating diseases or conditions.
“The clinical experience generated during this initial study phase will be critical for the future of the therapy, as many of these patients are not good candidates for traditional surgical tricuspid valve interventions due to their poor right heart functions and are higher risk due to co-morbidities,” said Vinayak (Vinnie) Bapat, chief of cardiothoracic surgery at the Minneapolis Heart Institute (Minneapolis, USA) and co-principal investigator in the study. “We are optimistic that these early learnings will help fuel additional clinical research and device innovation around this treatable disease.”
The Intrepid transcatheter valve is the same valve being evaluated for the treatment of symptomatic mitral valve regurgitation in the transfemoral mitral early feasibility study. The device is implanted using a transfemoral delivery catheter, which assists physicians in delivering and placing the valve through a catheter inserted in the femoral vein.
