Massive Atrial Thrombosis: A Serious Complication of the Maze Procedure Triggered by Heparin-Induced Thrombocytopenia (HIT)

Atrial fibrillation is one of the most common cardiac arrhythmias, classically presenting with an “irregularly irregular” rhythm or without chest pain, palpitations, shortness breath, lightheadedness, fatigue. The maze procedure open-heart operation that creates a carefully designed incisions and ablations in atrial myocardium. Although it procedure, serious complications may happen. Herein, we report on 76-year-old man who presented pain was found to have multi-vessel disease coronary angiogram. He underwent artery bypass COX-maze which complicated by massive thrombosis atria superior vena cava following ablation line, secondary heparin-induced thrombocytopenia, extremely rare. central focus this paper present rare complication stress importance rigorous follow-up anticoagulation therapy patients undergoing procedure. To our knowledge, are first such case diffuse large thrombi triggered thrombocytopenia (HIT) type II after
