The Regent mechanical heart valve, a supra-annular valve, delivers exceptional hemodynamics and performance while also maintaining its long-term legacy for structural integrity and durability.
Exceptional Hemodynamics
The Regent mechanical valve features a low implant height and either flex or standard cuff options. It is also radiopaque for improved visualization during x-ray and fluoroscopy. Yet what particularly distinguishes the Regent valve are features such as:
Single-digit gradients, even in valve sizes as small as 19 mm1
85° leaflet opening angle offers improved laminar flow and reduces turbulance2-4
Typically larger effective orifice areas (EOA) than competitors’5,6
Rapid and significant reduction in left ventricular (LV) mass5
ROOT ENLARGEMENT VERY RARE (eg, 1%)5,7
