Cor Pulmonale

Question 1

Cor Pulmonale

Answer 1

Altered RV structure and/or function in the context of chronic lung disease and is triggered by the onset of pulmonary HPN

Question 2

Acute RV dilatation and failure occurs d.t. sudden rise in pulmonary pressures (massive pulmonary embolism) but RV does NOT develop hypertrophy

Answer 2

Acute Cor Pulmonale

Question 3

More slowly evolving and progressive pulmonary HPN –> both RV HYPERTROPHY and DILATION

Answer 3

Chronic Cor Pulmonale

Question 4

MC symptom of cor pulmonale

Answer 4

dyspnea

Question 5

Happens d.t. backflow from R sided heart failure

Answer 5

abdominal pain and ascites

Question 6

Increase in the intensity of the holosystolic murmur of TR w/ INSPIRATION

Answer 6

Carvallo’s sign

Question 7

A late finding and is secondary to low CO

Answer 7

Cyanosis

Question 8

ECG findings in Cor Pulmonale

Answer 8

P pulmonale ( p waves > 2.5 mV in leads II and/or VI)

RAD and RV hypertrophy

Question 9

Chest radiography findings in Cor Pulmonale

Answer 9

enlargement of the main PA, hilar vessels and descending R PA

Question 10

2D echo findings in Cor Pulmonale

Answer 10

R sided chamber enlargement w/ associated dysfunction; pulmonary HPN

Question 11

Identifies obstructive, restrictive pulmonary parenchymal disease

Answer 11

Spirometry

Question 12

Identifies thromboembolic diseases, pulmonary interstitial diseases

Answer 12

Chest CT scan
