ATLANTA, March 28, 2025 /PRNewswire/ — MiRus is pleased to announce the launch of the US multi-center Early Feasibility Study of the Siegel™ 8-Fr aortic transcatheter heart valve (THV). The first two cases were successfully performed this week by Pradeep K. Yadav MD, Director of Structural Interventions, and Vinod H. Thourani MD, Marcus Chairman of Cardiovascular Surgery, Piedmont Heart Institute, Atlanta. Both patients were discharged without complications the next day.
MiRus Siegel™ TAVR
The Siegel valve represents several firsts in TAVR: 8 French delivery sheath allowing less invasive procedures and broader patient access, particularly for women; the only Nickel-free THV allowing treatment of the 20% of Americans suffering from Nickel allergies; precise delivery due to lack of foreshortening and intrinsic commissural alignment; dry porcine pericardial leaflets with anti-calcification treatment and with the valve pre-mounted on the balloon.
“Our initial experience is very positive,” commented Pradeep K. Yadav, MD. “Siegel is much less invasive then current devices and can be placed very precisely due to the lack of foreshortening. This should lead to lower pacemaker rates. The hemodynamics are excellent due to the radial strength and porcine pericardial leaflets.”
The combination of low delivery system profile and excellent hemodynamics is made feasible by the unique properties of the Rhenium alloys pioneered by MiRus including high yield strength, fatigue resistance and minimal recoil.
“In these first two cases, the Siegel valve performance is impressive,” stated Vinod H. Thourani MD, Marcus Chairman of Cardiovascular Surgery and the Marcus Valve Center, Piedmont Heart Institute. “8 French system with such precise placement and low gradients and no PVL is not a combination I ever expected in THV. A THV without nickel is also much needed.”
