Kawasaki disease: multiple giant coronary aneurysms intervention and pacemaker implantation due to complete heart block—a case report
Early intravenous immunoglobulin (IVIG) is the standard treatment for Kawasaki disease (KD) to reduce the incidence of coronary aneurysms. Patients with atypical presentation or who live in a rural area are less likely to receive treatment in the early stage of presentation and are more likely to develop severe complications. There is little consensus on how to treat coronary aneurysms effectively in the acute or subacute stage especially when giant aneurysms develop that compromise cardiac function. This case study is of a 19-month-old girl who initially was not treated as KD and developed multivessel giant coronary artery aneurysms (CAAs) (>8 mm), acute myocardial infarction, and complete heart block despite late intravenous IVIG administration. Multiple attempts of percutaneous coronary intervention (PCI) failed to open the occlusion in the right artery; therefore, bradycardia persisted. The girl received a permanent pace-maker and was doing well at 12-month follow up.
