THE ABILITY OF THE RADIUS OF PROXIMAL ISOVELOCITY SURFACE AREA TO ASSESS THE ANATOMIC AND HEMODYNAMIC SEVERITY OF MITRAL STENOSIS AFTER FIXING ALIASING VELOCITY

In the subset of patients who underwent BMV, the ratio IVRT/Te'-E correlated with LAP before BMV (r=0.74, p=0.009), however, PISA-r correlated also strongly with LAP (r=0.806, p=0.003), and was proven to be better than IVRT/Te'-E by multivariate regression analysis Conclusions Provided tha...

Description
Summary:In the subset of patients who underwent BMV, the ratio IVRT/Te'-E correlated with LAP before BMV (r=0.74, p=0.009), however, PISA-r correlated also strongly with LAP (r=0.806, p=0.003), and was proven to be better than IVRT/Te'-E by multivariate regression analysis Conclusions Provided that Val is set to a constant of 33 cm/s, PISA radius can effectively assess anatomic and hemodynamic severity of MS. Our study suggests PISA radius as a simple alternative to the tedious IVRT/Te'-E, for estimation of LAP in those patients.
