摘要:
AbstractWe investigated the impact of the atrial communication on the mitral valve area calculation after percutaneous mitral balloon valvotomy in 17 patients (15 women, 2 men; mean age 56 ± 4 years). The hemodynamic measurements and mitral valve area calculations were performed with and without balloon occlusion of the atrial septal puncture site. The mitral valve area determined with balloon occlusion was significantly smaller than the mitral valve area determined without occlusion (1.6 ± 0.1 vs. 1.9 ± 0.1 cm2,P<0.01), and was similar to the echocardiographically determined valve area (1.6 ± 0.1 cm2). This decrease in the calculated mitral valve area with occlusion was associated with a decrease in the measured cardiac output, without a change in the mitral valve gradient or the diastolic filling period. Occlusion of the atrial septal puncture site may permit more accurate determination of the mitral valve area and thus provide a better reference point for future comparison should the question of restenosis ar
