Abstract PDF: Acute limb ischemia (ALI) due to an embolism is associated with high mortality rate and poor prognosis, and early diagnosis with prompt revascularization is required to reduce the risk of limb amputation or even death. The etiologies of ALI are diverse, and it includes an embolism from the heart and thrombotic occlusion of the atherosclerotic native vessels, stents, or grafts. An uncommon cause of ALI is acute arterial thromboembolism, and atrial fibrillation (AF) is the single most important risk factors for systemic thromboembolism. It is important to correctly identify the source of ALI for secondary prevention, as it depends on the underlying cause. Percutaneous transluminal angioplasty (PTA) has been proven to be a safe and effective treatment for focal atherosclerotic and thrombotic occlusive diseases of the aorta and its major extremity branches. Herein, we report on a 77-year-old female patient with acute upper limb ischemia, treated by PTA using a catheter-guided thrombectomy. He was newly diagnosed with paroxysmal AF (PAF) while evaluation the cause of his acute arterial thromboembolism. We recommend that cardiologists always consider PAF as a possible diagnosis even in patients without any history of AF under ALI because it is possible to develop thromboembolism in clinical practice.

Abstract PDF: BACKGROUND
This study was conducted to provide a comparison between the clinical outcomes of primary percutaneous coronary intervention (PCI) and that of fibrinolysis followed by routine invasive treatment in ST elevation myocardial infarction (STEMI). METHODS: A total of 184 consecutive STEMI patients who underwent primary PCI or fibrinolysis followed by a routine invasive therapy were enrolled from 2004 to 2011, and their major adverse cardiovascular events (MACEs) were compared. RESULTS: Among the 184 patients, 146 patients received primary PCI and 38 patients received fibrinolysis. The baseline clinical characteristics were similar between both groups, except for triglyceride level (68.1±66.62 vs. 141.6±154.3 mg/dL, p=0.007) and high density lipoprotein level (44.6±10.3 vs. 39.5±8.1 mg/dL, p=0.005). The initial creatine kinase-MB level was higher in the primary PCI group (71.5±114.2 vs. 35.9±59.9 ng/mL, p=0.010). The proportion of pre-thrombolysis in MI 0 to 2 flow lesions (92.9% vs. 73.0%, p < 0.001) was higher and glycoprotein IIb/IIIa inhibitors were administered more frequently in the primary PCI group. There was no difference in the 12-month clinical outcomes, including all-cause mortality (9.9% vs. 8.8%, p=0.896), cardiac death (7.8% vs. 5.9%, p=0.845), non-fatal MI (1.4% vs. 2.9%, p=0.539), target lesion revascularization (5.7% vs. 2.9%, p=0.517), and stroke (0% vs. 0%). The MACEs free survival rate was similar for both groups (odds ratio, 0.792; 95% confidence interval, 0.317–1.980; p=0.618). The clinical outcome of thrombolysis was not inferior, even when compared with primary PCI performed within 90 minutes. CONCLUSION: Early fibrinolysis with optimal antiplatelet and antithrombotic therapy followed by appropriate invasive procedure would be a comparable alternative to treatment of MI, especially in cases of shorter-symptom-to-door time.

Abstract PDF: Bee sting causes mild symptoms such as urticaria and localized pain, and severe symptoms including anaphylaxis, cardiovascular collapse, and death. We reported on a patient with arterial thrombotic occlusion and severe ischemia in the lower limb after multiple bee stings. The patient was stung 5 times and complained of pallor, pain, and coldness in the left toe, and did not have dorsalis pedis pulsation. Computed tomography angiography showed multiple thrombotic occlusion of the anterior and posterial tibial artery below the knee. Local thrombolytic therapy using urokinase was administered and the occluded arteries were successfully recanalized.

Abstract PDF: Nephrotic syndrome is associated with a hypercoagulable state, which results in thromboembolism as one of its main complications. Various pathogenetic factors that cause the hypercoagulable state in nephrotic syndrome have been recognized. We report on a 19-year-old female with a minimal-change disease who developed pulmonary thromboembolism combined with intracardiac thrombus while on tapering steroid. Our patient showed hypoalbuminemia with an episode of shock, and was successfully treated with thrombolysis and anticoagulation therapy.

Abstract PDF

Pulmonary thromboembolism (PTE) increases the pressure of the right ventricle and leads to symptoms and signs, such as dyspnea and hypoxia. If PTE causes hemodynamic instability, thrombolytic therapy should be considered. A mechanical thrombectomy is an alternative treatment to thrombolytic therapy and should be considered when thrombolytic therapy is contraindicated. Various devices are used in mechanical maceration and catheter-directed thrombolysis, but there is no standard mechanical device for PTE as yet. We report here on 2 clinical experiences of mechanical thrombectomy using the Arrow-Trerotola percutaneous thrombolytic device to remove residual clots after systemic thrombolysis in patients with massive PTE.

Abstract PDF: Myxoma is the most common type of primary cardiac tumor and about 75% of myxomas occur in the left atrium of the heart. Most myxomas are diagnosed by echocardiography. The growth rate of myxoma is clearly unknown and newly developed myxoma is difficult to understand clearly the onset of growth. We describe the case of a newly developed huge left atrial myxoma (7x7 cm)which showed no echocardiographic evidence of the tumor four years ago. Four years later the patient underwent transthoracic echocardiography due to preoperative evaluation that was normal. Nine months later, she presented with dyspnea. Transthoracic echocardiography showed a large mass located in left atrium. Pathology showed a myxoma that measured 7x7 cm implying a growth rate of 0.15x0.15 cm/month.
