[Does effective cardioversion after surgery for valvular heart disease improve hemodynamic indicators?].
In 55 patients aged 47 +/- 6 years successful electrical cardioversion of atrial fibrillation was made. 24 hours before and after cardioversion, ekg and M-mode, 2-D and Doppler echocardiography was performed. Important improvement in ejection fraction (Simpson method), (p < 0.005) and in stroke index (Simpson method, p < 0.01; Doppler method, p < 0.005) was found in 64% of pts. Pts with haemodynamic improvement (HI) were significantly younger, had smaller, left atrial area in apical two-chamber view and left ventricular diastolic diameter and longer pulmonary acceleration time. In pts with HI the duration of AF was significantly shorter and closed mitral commissurotomy less frequent (p < 0.05). Restoration of mechanical atrial function (A-wave) was found in 44% of pts. In pts with A-wave HI was more often (p < 0.001). There was no correlation between maximal peak A-wave flow velocity and HI.
