    A 7-year-old Golden Retriever with mild exercise intolerance and presence of an arrhythmia was referred to Nihon University. Electrocardiographic findings included wide QRS complexes, irregular R–R intervals, small irregular baseline undulations and no P waves. Thoracic radiography revealed a large mass of soft tissue opacity obliterating the cranial cardiac silhouette and the dilation of the pulmonary artery silhouette. Transthoracic echocardiography showed a type III pulmonary artery flow pattern, but it did not reveal the presence of a mass in the cranial mediastinum. Computed tomography angiography identified an enlarged right auricle that was consistent with a right auricular aneurysm in the region of the suspected mass. This case was therefore diagnosed with a right auricular aneurysm. These findings suggest that computed tomography angiography may be a useful diagnostic tool in the diagnosis of the right auricular aneurysm.

    呼吸困難を主訴に来院した猫2例に胸水貯留が認められ,心臓超音波検査によりCaval syndromeと診断した。1例は,頚静脈からstring-type horsehair brushを用いて吊り出しを実施できたが,もう1例は左右頚静脈からの挿入が不可能であったため,右側開胸による流入遮断法を併用した右心房切開術により虫体摘出を実施した。術後2例とも胸水の貯留は速やかに改善されたが,1例は約5カ月後に死亡し,もう1例は現在も良好に経過している。猫の胸水貯留の鑑別診断にCaval syndromeも考慮する必要性が示唆された。

    Six-year-old female intact mixed breed dog was referred to Azabu University Veterinary Teaching Hospital because of bradycardia. High-grade second-degree atrioventricular block (AV block) was diagnosed. Although the dog was completely asymptomatic and no previous history of cardiac events was noticed, the artificial cardiac pacemaker (AP) was implanted because high-grade second degree AV block may progress to third-degree AV block and left ventricular enlargement was noticed. However, left ventricular function deteriorated over time and left ventricular enlargement worsened. Dilated cardiomyopathy was suspected since worsening of LV enlargement and systolic function. Sixteen months after pacemaker implantation, the dog began to show exercise intolerance. It has been approximately four year at the time of writing, and the dog was medically managed.
