Disappearance of Spontaneous Echographic Contrast after Balloon Mitral Valvuloplasty: An Indicator of Sustained Hemodynamic Improvement

In three patients undergoing mitral balloon valvuloplasty for mitral stenosis transesophageal echocardiography was performed before, immediately after, and 6 months after the procedure. In the one patient with persistent hemodynamically favorable result, the spontaneous echocardiographic contrast, which was seen in all three preoperatively, did not recur; in the other two patients the phenomenon was observed again after 6 months. We conclude that the disappearance of spontaneous echocardiographic contrast might be a functional morphological measure of sustained hemodynamic improvement after balloon mitral valvuloplasty.
