We report two cases, a 58-year-old male and a 60-year-old female with acute aortic occlusion probably ascribable to intracardiac thrombosis associated with atrial fibrillation. Thrombectomy was performed at about 5.5 hours and 4 hours respectively, after the onset of occlusion, and revascularization was successful. To prevent MNMS after revascularization, about 2, 000ml of blood was taken from the femoral vein of the male patient, and 1, 000ml of blood from the female patient, and this blood was returned in the form of abluted erythrocytes in transfusion through a cell saver to the patients. We suspected slight myoglobinuria after the operations, but they did not develop MNMS because a urine volume of about 3, 000ml was maintained by administration of infusion solution and diuretics and by replenishment of electrolytes and correction of acidosis. It was concluded that the technique involving the removal of a large volume of blood from distal veins and its transfusion through a cell saver was effective in preventing MNMS.

A 67-year-old man presented complaining of unstable angina. Coronary angiography revealed 50% stenosis of the left main trunk of the left coronary artery and a coronary artery aneurysm in the left anterior descending artery (LAD) #6. Furthermore, significant stenosis was noted in the peripheral LAD #7 and #9. The patient had hepatitis C, probably due to an earlier transfusion, and was suffering from liver cirrhosis (Child-Pugh classification grade A) and advanced thrombocytopenia. We anastomosed the saphenous vein graft (SVG) to the LAD and diagonal branch by off-pump coronary artery bypass grafting; we did not treat the aneurysm. There were no postoperative complications and the patient's progress was good. On postoperative coronary angiography, the aneurysm was occluded and the patency of the SVG was satisfactory.

We experienced the coronary artery bypass grafting (CABG) with essential thrombocythemia (ET). A case is a man of 73 years old. As for him, 3 vessel disease including left main trunk was recognized on coronary angiography, and it was planned CABG. However, we recognized blood cell aberration in blood examination, and it was diagnosed as ET. ET is classed as a chronic myeloproliferative disorder. It has two opposite tendencies, a bleeding tendency and thrombus tendency. Ischemic heart disease to merge ET is acute myocardial infarction by thrombus in case of most, and there are a few cases to need blood circulation reconstruction of coronary artery for angina pectoris. Perioperative hemorrhage and postoperative graft closure become a problem in CABG with ET. With the hydroxycarbamide which is DNA synthesis inhibitor of a platelet count, a function controlled it, and enforced CABG. He doesn't have any cardiac events and complications due to ET for 7 years post CABG. We report this case with a review of the literature.

Apical ballooning cardiomyopathy (Takotsubo or ampulla cardiomyopathy) is a well-known transient and localized left ventricular (LV) dysfunction characterized by apical severe hypokinesis, typical electrocardiogram (ECG) changes of negative T, and a lack of organic lesions of the coronary arteries which could cause myocardial ischemia leading to segmental asynergy. Here we report on two cases of transient cardiomyopathy showing atypically localized asynergy, which is different from Takotsubo cardiomyopathy. Case 1 was diagnosed as atypical Takotsubo cardiomyopathy, and the current findings suggest case 2 was viral myocarditis. These cases suggest that there exist variant patterns of transient cardiomyopathy, and non-invasive and serial clinical evaluations are important for differential diagnosis in acute and atypical cardiomyopathy.
