Plain-English summary
Three dogs with a congenital heart defect called a ventricular septal defect (VSD) were treated using a special coil to close the hole in their hearts. These dogs showed no symptoms and had normal chest X-rays and ECGs before the procedure. The coil was successfully placed in all dogs, and while a small amount of blood shunting remained, it was not clinically significant. After one year, the coils were found to be safely covered with tissue, and there were no major complications. This method appears to be a safe option for closing small heart defects in dogs.

Abstract
The purpose of this study was to evaluate the feasibility, safety, and efficacy of transcatheter closure in dogs with a congenital perimembranous ventricular septal defect (VSD) by using a detachable coil. No dogs showed any symptoms, and results of chest X-rays and ECGs were normal. The diameters of VSD ranged from 2 to 4 mm on echocardiogram. The defect was 2-2.5 mm from the aortic valve. A detachable coil (size 5 mm with 5 loops) designed for patent ductus arteriosus was delivered via the transarterial route. The device was successfully employed in all dogs. A minimal residual shunt was observed in all dogs even though Qp/Qs decreased. Hemolysis and a rate-dependent right-bundle branch block were observed in 1 dog, but there was no clinical significance. No major complication was noted. Pathologic examination after 1 year revealed that the coils were covered with tissue without significant damage to the His-Purkinje conduction system. In conclusion, transcatheter closure of a small perimembranous VSD with a detachable coil can be achieved without major complications or significant pathologic damage at the lesion site.
