Recent findings In the clinical setting, acute cor pulmonale is mainly observed as a complication of massive pulmonary embolism or acute respiratory distress syndrome. In acute respiratory distress syndrome, the worsening effect of mechanical ventilation has been recently emphasized. Summary As a general rule, the treatment consists in rapidly reducing resistance to blood flow in the pulmonary circulation, obtained by a specific strategy according to etiology. © 2009 Lippincott Williams & Wilkins, Inc.
