Abstract

うっ血性心不全の症状を呈して死亡したアミメキリン(Giraffa camelopardalis reticulata)の心臓を病理学的に検索した。心臓は拡大して丸みを帯び,両心室腔は著しく拡張していた。左心室内には前乳頭筋と後乳頭筋の位置に2個の硬い灰白色腫瘤病変(それぞれ6×4cm,8×3cm)が認められた。腫瘤は乳頭筋の頂上部.腱索ならびに僧帽弁弁尖の一部を巻き込んでいた。また,左心房の心内膜面には噴流病変が形成されていた。病理組織学的に,これらの腫瘤病変は腱索に主座した心内膜炎の瘢痕化病巣(線維性心内膜炎)とみなされた。

An 18-year-old female reticulated giraffe (Giraffa camelopardalis reticulata), which had shown signs of congestive heart failure, was examined cardiopathologically. The heart was grossly enlarged and rounded. Both ventricular cavities were noticeably dilated. In the left ventricular wall, two hard masses of greyish-whitish in color were found on the upper portions of the anterior and posterior papillary muscles (6×4cm and 8×3cm, respectively). The chordae tendineae and a part of the leaflets of the mitral valve were involved in both of the mass lesions. On the endocardial surface of the left atrium, there were opaque, wrinkled areas of endocardial thickening characteristic of jet lesions. Microscopically, the mass lesions were of organized thrombotic endocarditis in the chordae tendineae, regarded as fibrous endocarditis.
