[Echocardiography of operated heart. Assessment of results of mitral valvuloplasty].
OBJECTIVE
To assess results of surgery and to elaborate criteria of noninvasive diagnosis of cardiac function in patients with rheumatic mitral disease after reconstructive interventions on mitral valve.


METHODS
Patients (n=192, mean age 41.2+/-1.2 years) with pure mitral stenosis (76%) and combined mitral valve disease with prevalent stenosis (24%), and 32 practically healthy people (n=32, mean age 36.6+/-3.5 years, control group).


METHODS
Comprised transthoracic mono and two-dimensional echocardiography and doppler echocardiography. Results of intracardiac flow study were compared with data of invasive methods of investigation--intraoperative flowmetry and manometry, cardiac catheterization and intraoperative transesophageal echocardiography.


CONCLUSIONS
The following criteria of hemodynamically effective valvuloplasty were established: lowering of mean mitral valve pressure gradient by 54-65%; absence of regurgitation or lowering of mitral valve regurgitation fraction to < or =6% of total stroke volume. Significant increase of left ventricular stroke volume (by 22-27%), increase of mitral valve area (by 164-222%), decrease of left atrial diameter (mean decrease 17%) were also noted.
