Abstract: | A one-year-old female English Springer Spaniel with no previous history of cardiac disease presented to the Queen's Veterinary School Hospital following a blunt traumatic incident with an acquired, direct Gerbode defect and associated third-degree atrioventricular block. Two months after the initial incident, follow-up echocardiography showed a nearly closed Gerbode defect with just trivial residual flow. A 24-h Holter monitor indicated second-degree atrioventricular block with occasional junctional tachycardia. A reassessment 22 months later confirmed spontaneous closure of the previously acquired traumatic Gerbode defect, with 2:1 second-degree atrioventricular block. The dog remained clinically asymptomatic, and free of treatment. To our knowledge, this is the first reported case of spontaneous closure of a previously acquired traumatic Gerbode defect in a dog. |
