Findings of Cor pulmonale

Characteristic findings of Cor pulmonale

Common etiologies :

  • COPD
  • Interstitial lung disease
  • Pulmonary vascular disease (eg, thromboembolic)
  • Obstructive sleep apnea

Symptoms :

  • Dyspnea on exertion, fatigue, lethargy
  • Exertional syncope (due to decreased CO)
  • Exertional angina (due to increased myocardial demand)

Examination : 

  1. Peripheral edema
  2. Increased Jugular venous pressure with prominent a wave
  3. Loud S2
  4. Right sided heave
  5. Pulsatile liver from congestion
  6. Tricuspid regurgitation murmur

Imaging :

  • EKG : partial or complete RBBB , right axis deviation, right ventricular hypertrophy right ventricular enlargement

  • Echocardiogram : Pulmonary hypertension, dilated right ventricle, tricuspid regurgitation

Right heart catheterization: Gold standard for Dx showing right ventricular dysfunction, pulmonary HTN and no left heart disease.
