Coronary Sinus Thrombosis and Post-Myocardial Infarction Syndrome in Kawasaki Disease: Rare Causes of Pericardial Effusion.

The hypercoagulable state in Kawasaki disease (KD) may lead to complex cardiovascular sequelae. We present the case of a 2-month-old infant with complete KD complicated by giant coronary artery aneurysms, coronary sinus thrombosis, and post-myocardial infarction syndrome (Dressler syndrome), resulting in 2 distinct episodes of pericardial effusion. ( Level of Difficulty: Intermediate. ).
