Figure.3 Basis of hemodynamic changes after constriction
The decreasing pressure is restricted to be transmitted to the
pericardial cavity through the intrathoracic when inhaling, and with a
decrease of intrathoracic pressure. The constrictive pericardium makes
the diastolic function impaired, and lead to a difference of pressure
between left atrial and pulmonary vein, which causes a decreasing flow
into the left ventricular. So we can see the shift of ventricular septum
during the breathing. LA= left atrium RA= right atrium, LV= left
ventricle, RV= right ventricle, PV= pulmonary vein, P= pressure.
