Here’s a case of a 5-month-old female Labrador Retriever with a heart murmur. Take a look at the radiographs and post your comments!
Loss of cranial waist on the RL view, buldge at the area of the aorta/MPA on the LL view, prominent left atrium, prominent aortic arch on the VD view with cardiomegaly, mostly of the left ventricle.
This could be due to aortic/subaortic stenosis?
The cardiac silhouette appears slightly enlarged and prominence of the aortic arch is evident in all the projections. On the DV view there is a mild widening of the cranial mediastinum. In addition there is an increase of dimension of the left atrium and the pulmonary vein but not signs of congestive heart failure. Dilation of the intrathoracic oesophagus (sedation or dyspnea?)
In the light of the clinical signs my differential is:
– aortic stenosis
– pulmonic stenosis
unlikely
– aneurysm of the right atrial auricula
– PDA
– Aortic body tumor
Great, we have some good differentials here. It’s a young dog, so we are thinking congenital cardiac anomaly. How do the radiographic findings fit with the two heart murmurs ausculted?
Aortic stenosis (most likely subaortic stenosis) would be my diagnosis as the patient has the enlarged aortic arch with mild left-sided cardiomegaly and systolic murmurs.
