Doberman
Radiographic Report
The VHS is 9.7 which is within the normal range (≤10.5). The VLAS is 2.3 which is within normal limits (normal 1.8-2.3). There was also no evidence of any other abnormalities
Dobermans are considered a high-risk breed for dilated cardiomyopathy (DCM). This in combination with the finding of a murmur consistent with mitral regurgitation makes this dog very high-risk at this time. Left ventricular dilation and systolic dysfunction (e.g. DCM) cannot be ruled out based on a normal VHS and VLAS especially in a high-risk breed like the Doberman. Thoracic radiographs, in general, have limited utility in screening for DCM in the dog. Additional testing would still be indicated in this case even though the VHS and VLAS were normal. If the VHS was enlarged, in particular > 11.5, the index of suspicion would be increased. However, additional confirmatory testing (e.g. echocardiogram) would be needed to confirm a diagnosis of DCM or rule it out.
Clinical History
Signalment: 7-year-old, MN, Doberman (35.3 kg)
The dog was presented for annual health evaluation. According to the owner the dog is apparently healthy . Auscultation revealed a 2/6 (soft, focal) left apical systolic heart murmur. Thoracic radiographs were performed.
