| الوصف: | Aim To simplify proximal isovelocity surface area (PISA) method for mitral valve area (MVA) calculation that does not necessitate the usage of a calculator and angle correction, and to compare values estimated using this novel method with the values obtained by the conventional PISA, planimetry and pressure half-time (PHT) methods.Methods We evaluated patients with a wide range of mitral stenosis (MS) severity. The MVA was measured by the methods of PHT (MVA PHT), planimetry (MVApl), conventional PISA (MVAC-PISA) and the novel method of simple PISA (MVAS-PISA). Application of simple PISA was performed subsequently by division of the peak mitral inflow velocity by four; measurement of the radius by adjusting the aliasing velocity to this value; square of the radius gives the MVAS-PISA. Results Twenty patients were enrolled in the study. Peak and mean pressure gradients of patients were 20 ± 6 mmHg and 10±4 mmHg,respectively. The average values of MVApl, MVAPHT, MVAC-PISA, and MVA S-PISA were 1,54±0,41, 1,65±0,40, 1,58±0,42, 1,57 ± 0,44 cm2, respectively. MVAS-PISA had a strong correlation with the MVAC-PISA, MVApl and MVAPHT . Furthermore, there was no signi- ficant difference between simple PISA and the other methods. The agreement between planimetry and simple PISA methods for detecting severe mitral stenosis (MVA |
