resulting in an increase in peripheral
vascular resistance. Furthermore, temporary increase in venous return
due to relief of caval compression and the additional blood shifting from
the contracting uterus into the systemic circulation result in additional
hemodynamic stress, leading to increase pulmonary hypertension
and tore fractory right heart failure. Pulmonary embolism risk also
continues after delivery, therefore careful monitoring of the patient and
supportive treatment is needed to prevent development of right heart
failure
