title: [Percutaneous transvenous mitral commissurotomy vs open mitral commissurotomy: evaluation of results by color Doppler and two-dimensional echocardiography].
abstract: The effects of percutaneous transvenous mitral commissurotomy (PTMC) and open mitral commissurotomy (OMC) were evaluated in 18 patients who underwent PTMC and 16 patients who underwent OMC, before and within one month of the procedure, using two-dimensional and color Doppler echocardiography. There was no significant difference between the two groups in the mitral valve area, the severity of mitral stenosis, or cardiac function before the procedure. The mitral valve area after PTMC as measured by two-dimensional echocardiography and continuous wave Doppler echocardiography increased from 1.07 +/- 0.24 cm2 to 2.01 +/- 0.42 cm2 (p < 0.001), and from 0.99 +/- 0.26 cm2 to 1.76 +/- 0.23 cm2 (p < 0.001), respectively. The mitral valve area after OMC measured by two-dimensional echocardiography and continuous wave Doppler echocardiography increased from 1.04 +/- 0.24 cm2 to 1.78 +/- 0.41 cm2 (p < 0.001), and from 0.95 +/- 0.32 cm2 to 1.62 +/- 0.46 cm2 (p < 0.001), respectively. The mitral valve areas after PTMC did not differ significantly from those after OMC by either method.
