Description
- Cor pulmonale is right ventricular (RV) failure secondary to an altered pulmonary process that results in a loss of functional capillary vascular bed, and in excessive pulmonary artery pressure and resistance (PVR).
- Cor pulmonale is not the result of a primary congenital heart defect.
ALERT
- In newborns, the RV muscle mass is comparable to that of the the left ventricle.
- RV failure from pulmonary hypertension (PH) occurs but is rare in newborns.
- RV failure in newborns is usually a consequence of hypoxemia, ischemia, metabolic acidosis (e.g., persistent fetal circulation), and/or premature restriction/closure of the intrauterine ductus arteriosus.
