Question

On echocardiography, dilated cardiomyopathy in dogs is characterized best by which of the following findings?
(A). Decreased ejection fraction
(B). Decreased fraction shortening
(C). Increased mitral valve E-point to septal separation (EPSS)
(D). Decreased LA/AO ratio
Choose the correct answer from the options given below:

• A. (A), (B) and (D) only
• B. (A), (B) and (C) only
• C. (A), (B), (C) and (D)
• D. (B), (C) and (D) only

Hint:

To remember canine DCM echo findings:
- Ventricles become thin and weak \(\rightarrow\) Decreased contractility (EF & FS drop).
- Ventricles dilate \(\rightarrow\) Mitral valve cannot reach the septum \(\rightarrow\) EPSS increases.
- Blood backs up \(\rightarrow\) Left atrium dilates \(\rightarrow\) LA/AO ratio increases.

Answer 1

The Correct Option is B
