Abstract

We performed serial color Doppler echocardiographic studies prospectively before and after double balloon or Inoue balloon mitral valvuloplasty in 44 patients (mean age 45 +/- 13, range 20-74) with pure rheumatic mitral stenosis (by angiography) selected in a case-control manner to compare the incidence and severity of mitral regurgitation. After balloon dilation, mitral valve area increased from 0.9 +/- 0.2 to 1.5 +/- 0.4 cm2 (p < 0.001) in the double balloon group and from 0.9 +/- 0.3 to 1.5 +/- 0.3 cm2 (p < 0.001) in the Inoue balloon group. Twenty-four hours after balloon dilation, 3 patients in the double balloon group and 12 patients in the Inoue balloon group developed moderate to severe mitral regurgitation (p < 0.05). The severity of mitral regurgitation tended to persist or progress during follow-up in both groups, although improvement could also be observed. Two patients with severe mitral regurgitation in the Inoue balloon group underwent mitral valve replacement during follow-up. In conclusion, double balloon and Inoue balloon techniques are both effective in relieving significant mitral stenosis. However, Inoue balloon technique may be associated with slightly higher frequency of mitral regurgitation.
