Results The A-wave maxìmum velocìty is hìgher than E-wave maxìmum velocity both in blood flow of tricuspid and mitral valve. And E-wave and A-wave of trìcuspid valve higher than mitral valve sìgnifìcantly. There ìs no correlatìon between weeks gestatìon and the blood velocìty of trìcuspìd and mìtral valves. And there is a posìtive correla- tìon between the E/ A ratios and the gestatìonal weeks. The dìastolìc and systolìc tìme of left ventrìcular (LV) and rìght ven- tricular (RV) have a positìve correlation with the week s gestatìon. and the
