Disorder - Pulmonary stenosis

Organ Systems Involved
Cardiovascular

Alternative Names
Valvular pulmonic stenosis
Pulmonic stenosis

Brief Description

This disorder is a malformation of the heart involving a narrowing in the area of the heart where blood is pumped to the lungs.

Presenting Signs

Many affected dogs, especially those under one year of age, do not show any signs of this condition. Those dogs that do show signs of pulmonary stenosis, may have a weaker than normal pulse with an abnormal rhythm and a heart murmur that can be heard with a stethoscope between the third and fourth left ribs. It may also be possible to feel a vibration at this location that is in time with the pulse. On the right-hand-side of the abdomen, fluid may accumulate under the skin. Affected dogs may show signs of reduced ability to exercise including gasping for air, and loss of consciousness or sudden death (in extreme cases) may be observed. Gums usually remain pink, however in extreme cases, these tissues may develop a blue tinge due to poor oxygenation of the blood.

Dogs at Risk

While both genders can be affected by pulmonary stenosis, males are more commonly affected than females in some breeds.
