Unexpected Evolution After Multivessel Coronary Artery Bypass Grafting in a Patient With Kawasaki Disease

Kawasaki disease (KD), also known as mucocutaneous lymph node syndrome, is an acute vasculitis that frequently affects medium-sized blood vessels. The disease is usually self-limiting and most commonly affects children under five years of age. It often affects the coronary arteries and is the leading cause of acquired heart disease in developed countries. We report the case of a teenage boy who had a long-standing diagnosis of Kawasaki disease, underwent coronary artery bypass grafting surgery, and had a complicated medical course following the surgery.
