Floating thrombi in the aortic arch are very rare and an unusual source of systemic embolism. Herein, a case of a 3-cm thrombus in the aortic arch is reported. It was a floating, highly mobile thrombus attached to the lesser curvature of the aortic arch. The patients had a hypercoagulable disorder induced by protein C and S deficiency. The thrombus was operatively removed with a favorable outcome.

A 53-year-old male patient who had suffered from acute myocardial infarction before a week was admitted due to postinfarction angina A mobile pedunculated left ventricular thrombus of 2.0-cm diameter which was overlooked in cardiac catheterization and ventriculographic study was diagnosed with transthoracic two-dimensional echocardiography. There was no exact clinical finding of left ventricular aneurysm and the thrombus was placed in the akinetic and hypokinetic apical portion. For preventing systemic embolism that was removed through a left ventriculotomy just prior to coronary artery bypass grafting.

Duplex sonography has been used to non-invasively diagnose carotid artery disease and to follow up patients with this disease. In carotid artery disease, carotid mobile thrombus and dissection are rarely detected by duplex sonography in patients with cerebrovascular events. In particular, carotid dissection occurs when a small tear forms in the tunica intima and makes 2 lumens in the carotid artery, including true and false lumens. This study reports 3 rare cases of carotid mobile thrombus, spontaneous carotid dissection, and carotid dissection in Takayasu arteritis.

Report of right atrial thrombus complicating pulmonary embolism after cardiac surgery is rare. A 54-year-old woman operated on the atrial septal defect 10 months ago was admitted for left pleuritic pain and dyspnea. Multiple segmental perfusion defects were detected in lung perfusion scan. Transesophageal echocardiography showed a large mobile right atrial mass attached to the free wall of the right atrium with a stalk. Despite the intravenous heparinization for 13 days, follow-up echocardiography revealed the right atrial mass had not diminished in size. The mass which was confirmed as an organizing thrombus was excised under cardiopulmonary bypass. The patient recovered uneventfully and was discharged on warfarin therapy.

Aortic thrombi are important because it can cause the central and peripheral embolizations. Aortic thrombi can occur anywhere in the aorta but extremely rare in ascending aorta without atherosclerosis, aneurysm, cardiosurgical or traumatic state. Systemic sclerosis (SSc) is an autoimmune disorder of connective tissue and it can involve multisystem. Enhanced coagulation pathways, decreased fibrinolysis, and endothelial dysfunction probably contribute to vascular events in SSc. We report a case of a highly mobile thrombus in the ascending aorta, presented as an acute embolic stroke in the patient with systemic sclerosis. Surgical removal was performed to prevent recurrent embolic events.

Sixty-three patients who underwent open mitral commissurotomy at Sejong General Hospital during last 10 years from the August, 1983 to June, 1993 were reviewed There were fifty-one women and twelve men, and the mean age was 34.2 years. According to the NYHA classification, the distribution of patient preoperatively was as follows: class I, 5 patients ; class II, 26 patients ; class III, 30 patients ; class IV, 2 patients, and mean duration of symptome was 4.5 years. The mean mitral valvular area measured with echocardiogram preoperatively was 0.92cm2. All patients underwent open mitral commissurotomy and 41 patients required additional procedures for relief of subvalvular stenosis or other valvular disease. There were no operative death. 63 patients had three different types of mitral stenosis : type I, mobile cusps without subvalvular change [21 patients] ; typeII, thickened cusps with subvalvular change [34 patients] ; type III, rigid cusps with severe subvalvular change [8 patients]. The valvular calcification was seen in 11 patients [17%] and 15 patients [24%] had left atrial thrombus. The duration of follow-up was from 1 month to 168 months [mean, 39.6 months] and there were no late death. Six patients required reoperation and one patient had embolic episode. Conclusively,the open mitral commissurotomy represents a safe surgical precedure for treating mitral stenosis, allowing a complete removal of atrial thrombosis if present, and even when associated with subvalvular changes.

We report a case of vegetation in a 4-year-old female with infective endocarditis, diagnosed by late gadolinium-enhanced (LGE) cardiovascular magnetic resonance (CMR) imaging. The patient had a history of primary closure for ventricular septal defect and presented with mild febrile sensation. No remarkable clinical symptoms or laboratory findings were noted; however, transthoracic echocardiography demonstrated a 14 mm highly mobile homogeneous mass in the right ventricle. On LGE CMR imaging, the mass showed marginal rim enhancement, which suggested the diagnosis of vegetation rather than thrombus. The extracellular volume fraction (${\geq}42%$) of the lesion was higher than that of normal myocardium. Based on the patient's clinical history of congenital heart disease and pathologic confirmation of the lesion, a diagnosis of infective endocarditis with vegetation was made.

Thrombosis in valve or left atrium after mechanical mitral valve replacement causes prosthetic valve dysfunction or thromboembolism. Early and adequate therapy is very important but clinically not easy. Thrombolysis can avoid reoperation-related risks and act as an optimal therapy for prosthetic valve thrombosis. This report describes three patients who were treated by using low molecular weight heparin (LMWH) and wafarin. Two patients, including one pregnant woman, had prosthetic valve thrombosis and immobility of valve leaflets, and one patient with recent cerebral infarction due to thromboembolism had thrombus in left atrium. Fraxiparine 0.3 cc (7,500 ICU AXa) was administrated subcutaneously twice or triple daily. At discharge, thrombosis in valve and left atrium were completely or near totally lysed and valve leaflets were normally mobile. During the period of thrombolysis and follow up, there were no complications in all patients.
