Thrombi in all four cardiac chambers in a patient with an old anteroseptal myocardial infarction and atrial flutter.

Cases with thrombi in multiple cardiac chambers are rare. We report an extremely rare case in which thrombi were formed in all four cardiac chambers at the same time. A 55-year-old man presented with biventricular failure and liver dysfunction. A 12-lead ECG and an echocardiogram revealed an old anteroseptal myocardial infarction with aneurysm formation and atrial flutter. A transesophageal echocardiogram and a CT of the chest revealed thrombi in the right and left atrial appendage, right ventricular apex and left ventricular aneurysm. Pulmonary emboli were also identified. Stasis of the blood due to ventricular dysfunction and atrial flutter was considered to be responsible. The patient died of multiorgan failure due to circulatory failure.
