Cor pulmonale
Updates to Article Attributes
Cor pulmonale is defined as a failure of the structure and function of the right ventricle in the absence of left ventricular dysfunction. It is caused by an underlying primary disorder of the respiratory system. It has a generally chronic and slowly progressive course, although acute onset or worsening with life-threatening complications can occur.
Pathology
Aetiology
- chronic obstructive pulmonary disease
- pulmonary manifestations of cystic fibrosis
- interstitial lung disease
- massive pulmonary emboli: for acute cor pulmonale
- acute respiratory distress syndrome: for acute cor pulmonale
Radiographic features
Plain radiograph
- central pulmonary artery enlargement 7
- changes consistent with underlying pulmonary disease as outlined above
Echocardiography
May show dilatation of the left ventricular cavity or thickening of the right ventricular free wall 6.
Treatment and prognosis
Cor pulmonale generally carries a poor prognosis. Long-term oxygen therapy is often considered the main treatment option.
History and etymology
From the Latin, cor: 'heart', and pulmonale, 'relating to the lungs', ultimately from the Latin pulmo meaning 'lung'.Therefore 'heart secondary (relating)to / relating to the lungs'.
