In both dogs and cats [[Pulmonary Oedema|pulmonary oedema]]  is a sign of left-sided congestive heart failure. In the cat pleural effusion may also be a side of left-sided congestive heart failure, whereas in the dog pleural effusion is always a sign of right-sided congestive heart failure. This species difference occurs because a proportion of the visceral pleural surface drains into the pulmonary veins, and this anatomic arrangement is more prominent in cats.

Description

  • Occurs when the left cardiac ventricle no longer pumps blood efficiently
  • When the left side of the heart encounters pumping problems, too much blood remains in the lungs and not enough of the oxygenated blood reaches the systemic circulation. This type of failure causes pulmonary congestion and edema as a result of increasing pressure from the growing volume of blood in the pulmonary circulation that is waiting to be pumped into the arterial circulation.

Signs

-Pulmonary congestion

-Pulmonary edema

-Pleural effusion

Causes

1. Mitral Valve Problems (Stenosis or Insufficiency)

2. Cardiomyopathies

3. Congenital Abnormalities

4. Myocardial Inflammation or Degeneration
