Plain-English summary

A 1.2-year-old male Standard Poodle had surgery to fix a heart defect and developed a serious heart rhythm issue called high-grade second-degree atrioventricular block about a day and a half later. This condition can cause the heart to beat irregularly, which can be concerning for pet owners. Fortunately, after receiving corticosteroids and some time to recover, the dog's heart rhythm returned to normal within 12 days. This case highlights a rare complication that can occur after heart surgery in dogs, but it shows that treatment can be effective.

Abstract

A 1.2-year-old male-intact Standard Poodle underwent transvenous placement of an Amplazter™ atrial septal occluder for correction of a large secundum atrial septal defect. Thirty-six hours post-operatively, the dog developed high-grade Mobitz type II second-degree atrioventricular block, which resolved with time and corticosteroid administration by 12 days after the procedure. This case report outlines the observation, treatment, and resolution of high-grade Mobitz type II second-degree atrioventricular block, a known complication of atrial septal occluder placement in humans, not previously reported in veterinary literature.
