Normal atrioventricular concordance and cardiac axis. Physiological vieussens valve with physiological right to left atrial shunt.
Pericardial effusion, cardiomegaly, dilated right atrium due to tricuspid insufficiency (see pulsed Doppler waveform), and last but not least, critically low cardiac function: no systolic thickening of myocardium during systole, in both ventricles, except the base of right ventricle. Ejection volume seems obviously low. Hyperechoic myocardium.
