Plain-English summary
A 1-year-old female Great Dane was examined before surgery for a third eyelid gland issue, but her heart test results were unclear. While standard echocardiography showed some signs of dilated cardiomyopathy (DCM), a more advanced test called tissue Doppler imaging revealed significant heart muscle issues. This advanced imaging helped confirm the diagnosis of DCM four months later. Early detection through tissue Doppler imaging can be crucial for managing heart problems in dogs.

Abstract
A 1-year-old healthy female Great Dane was referred for an echocardiographic examination prior to anesthesia and surgical correction of prolapse of the right third eyelid gland. Findings of a physical examination were normal. Conventional 2-dimensional and M-mode echocardiography revealed equivocal findings of dilated cardiomyopathy (DCM). Conversely, tissue Doppler imaging revealed a dramatic decrease in systolic and early diastolic radial myocardial velocity gradients, which were related to a decrease in endocardial velocities. Four months later, the diagnosis of DCM was confirmed via conventional echocardiography. In dogs with equivocal conventional echocardiographic findings of DCM, severe myocardial alterations may be detected via tissue Doppler imaging and this technique may enable early diagnosis of radial myocardial dysfunction.
