Multiplanar aortic valve aims to increase the effective orifice area via protruding its leaflet stent or stents into ascending aorta instead of aortic annulus.
The valve delivers excellent hemodynamic performance with low pressure gradients, large effective orifice areas and left ventricular mass regression also in patients with small annuli.
A novel multi-planned mechanical aortic valve for increasing the effective orifice area.
Before treatment the 81 year old patient was suffering from critical aortic stenosis with an effective orifice area of 0.
Frank Shannon, who completed the US cohort of the study commented, "MiCardia's unique Dynaplasty[R] provides a precise geometrical adjustment of the annulus shape without the reduction in effective orifice area that conventional restrictive annuloplasty dictates.
The valve's excellent hemodynamic performance was maintained over the study's 10-year period, with patients benefiting from statistically significant increases in effective orifice area (EOA), the area of the valve's opening for blood flow.
The SJM Regent(R) valve offers several important advantages, including excellent hemodynamic performance - facilitated by significantly larger effective orifice areas (or EOAs - the area of the valve's opening for blood flow) - even in smaller-size valves.
Patients also benefited from statistically significant increases in effective orifice area (EOA - the area of the valve's opening for blood flow).
