Diffuse vascular degeneration and contraction band necrosis cause sudden death in a canine model.
Case Report (n=1)
This case report describes sudden death in a young beagle caused by non-inflammatory medial degeneration of the arterial system and myocardial contraction band necrosis.

Single beagle case links sudden death to non-inflammatory vascular-myocardial degeneration; hypothesis-generating for comparative pathology and leaves mechanisms open.
A 9-month-old male beagle suddenly died without any clinical signs. Histopathologically, he showed acute circulatory insufficiency due to diffuse degenerative changes of blood vessels and exudation from arterioles and myocardial contraction band necrosis of the heart. The cardiac lesions were marked in the left ventricle and the vascular lesion consisted of medial degeneration of the arterial system extending from the main branches of the extramural coronary arteries to the arteriolar segments. These lesions showed no inflammatory changes.

Hoshiya et al. (2000) conducted a case report in Sudden death (n=1). A 9-month-old male beagle that died suddenly showed acute circulatory insufficiency due to diffuse degenerative changes of blood vessels and myocardial contraction band necrosis without inflammation.
