    Persistent left cranial vena cava with defect of right cranial vena cava was diagnosed pathologically in a 6-year-old male Shetland sheep dog suffering from heartworm disease and renal failure. Only one heartworm was surgically removed from the dog through the jugular vein. The examination of cardioangiography indicated the unusual cranial vena cava, though definitive diagnosis could not be made. The dog died on day 340 despite fluid therapy and medical treatment with trapidil, aspirin and aminophyline. Left cranial vena cava was found at necropsy, whereas no remnants of the right cranial vena cava was observed. No cardiovascular anomalies were detected.

    Two apparently healthy racehorses (horses 1 and 2) showed abrupt decelerations during a race and finished a long way behind the winners. ECG examinations of both the horses, shortly after the race, exhibited atrial fibrillation (AF). In particular, the AF of horse 1 coexisted with ventricular premature contractions (VPCs) on the ECG recording at 10 min after the race. The VPCs were frequent and multifocal. Horse 2 had no association with VPC. The repeated post-race examination revealed spontaneous disappearance of the AF with both of the horses resuming a normal sinus rhythm within 24 hrs. Thereafter, horse 1 had no start and retired from a race. On the other hand, horse 2 had 28 starts, winning 6 races, and 3 with placings. With no association with PVC, the prognosis as regards paroxysmal AF could be favorable in the racehorse.

    A case of arterial rupture that caused sudden death in a whooper swan (Cygnus cygnus) is described. Rupture was located at the origin of the left brachiocephalic artery. Histological examination of the vessel wall revealed degenerative changes in the media, resembling lesions seen in cystic medial necrosis.
