Question of the Day

Think pulmonic stenosis if you see right ventricular hypertrophy, because stenotic pulmonic valve blocks outflow from R ventricle (mostly in dogs). Follow this link to see an angiogram image of pulmonic stenosis.

Listen for a systolic murmur loudest on LEFT chest between the 2^nd and 4^th intercostal (IC) space; genetic link in beagles. Predilection seen in many breeds, including Eng. bulldog, min. Schnauzer, Scotties, Chihuahuas, Cockers, Boxers.

Pulmonic stenosis can be confused with aortic stenosis (also called sub-aortic stenosis), a systolic murmur which may be heard most loudly on the left chest between the 2^nd and 5^th intercostal (IC) space or at the thoracic inlet (lateral to trachea).

Mitral dysplasia and other mitral valve problems are heard further back on left at 5^th-6^th IC. More common in CATS.

Tricuspid dysplasia is heard further back on RIGHT at 5^th-6^th IC. Uncommon.

Expect a continuous murmur with PDA. Vast majority detected at first vaccination visit.
