[Changes in clinical-instrumental parameters in patients with mitral stenosis after balloon catheterization valvuloplasty of the mitral valve].
The results of mitral valvuloplasty using a balloon catheter were presented for 104 patients with mitral stenosis. Instrumental measurements and clinical symptoms were evaluated before the operation, 6 and 12 months after it (62 and 42 patients, respectively). The balloon dilatation has increased mitral orifice from 120.5 +/- 5.8 to 333.88 +/- 7.45 mm2, transmitral diastolic pressure gradient decreased from 22 +/- 1 to 7.91 +/- 0.6 mm Hg. All the patients benefited clinically: cough, blood spitting, lower limb edemas, protodiastolic murmur disappeared, dyspnea noticeably reduced. NYHA functional class I-II was established in 85% of the patients. The highest effect was achieved in patients with isolated mitral stenosis.
