RESUMO
Heart block is a relatively common arrhythmia in the adult horse. It may be a normal physiologic phenomenon or it may have pathologic implication. Four foals in which advanced heart block developed during anesthesia were unresponsive to atropine sulfate and supportive treatment alone. Resolution of the heart blocks was achieved after the addition of dopamine hydrochloride to the therapeutic regimen.

Seven puppies with concomitant congenital cranioventral abdominal wall, caudal sternal, diaphragmatic, and pericardial defects were treated surgically when they were between 10 and 12 weeks old. Three pups had ventricular septal defects that were not corrected. Diaphragmatic herniorrhaphy without extension of the diaphragmatic defect was performed in 6 pups. In one pup, paracostal extension of the diaphragmatic defect was necessary to decrease tension on the diaphragmatic closure. All pups were healthy at 6-month follow-up examinations, but 2 of 3 pups with ventricular septal defects had moderate generalized cardiomegaly evident on thoracic radiography. Early surgical correction of the congenital defects in these pups was usually simple because there were few or no thoracic adhesions, the dogs were small, the defects were small in 6 of 7 dogs, and the costal arch was pliable in each dog.

Five littermate Cocker Spaniels were born with concomitant pericardial, diaphragmatic, caudal sternal, and cranioventral abdominal wall defects. Three of the 5 pups had ventricular septal defects. A sixth pup with a cranioventral abdominal wall defect died 4 days after birth. No history of teratogen exposure was reported, and none of the pups from previous litters of the dam was affected. Each pup underwent successful surgical correction (without median sternotomy) of the diaphragmatic and cranial abdominal wall defects when they were 10 to 12 weeks old. The ventricular septal defects were not corrected. In 2 of 3 pups with ventricular septal defects, thoracic radiography 6 months after surgery revealed moderate generalized cardiomegaly. All pups were healthy one year after surgery.
