Název v původním jazyce

Improvement in left ventricular filling properties after relief of right ventricle to pulmonary artery conduit obstruction: contribution of septal motion and interventricular mechanical delay

Popis výsledku v původním jazyce

In 20 consecutive patients with congenital heart disease and RV to PA conduit obstruction, the following were prospectively assessed before and after percutaneous pulmonary valve implantation (PPVI): the septal curvature and LV volumes throughout the cardiac cycle by magnetic resonance imaging; RV to LV mechanical delay by 2D-echocardiographic strain imaging; and objective exercise capacity. Percutaneous pulmonary valve implantation led to a reduction in RV to LV mechanical delay (127.9+50.9 vs. 37.7+35.6 ms; P , 0.001) and less LV septal bowing in early LV diastole (septal curvature: 20.11+0.11 vs. 0.07+0.13 cm21; P , 0.001). Early LV diastolic filling (first one-third of diastole) increased significantly (17.5+9.4 to 30.4+9.4 mL/m2; P , 0.001). The increase in early LV diastolic filling correlated with the reduction in RV to LV mechanical delay (r 0.25 20.68; P 0.25 0.001) and change in septal curvature (r 0.25 0.71; P , 0.001).
