AbstractAbstract PDF
Cardiogenic embolic stroke accounts for approximately 20% of ischemic strokes and the likelihood of its recurrence is high. Paradoxical embolism may be an important cause of cardioembolic stroke, which can be evaluated through multiple diagnostic modalities including transesophageal echocardiography (TTE) or transcranial Doppler. A persistent left superior vena cava (PLSVC) is a rare congenital vascular anomaly, which mainly drains to the right atrium via the coronary sinus. Although rare, PLSVC draining into the left heart predisposes the patient to paradoxical embolism through a right-to-left shunt. We report on a 78-year-old female patient with an ischemic stroke associated with PLSVC draining into the left atrium through the pulmonary vein, which was investigated via TTE with an agitated saline test and computed tomography.

AbstractAbstract PDF
Although amiodarone is generally regarded as safe with a low incidence of associated arrhythmias, torsade de pointes (TdP) has been observed usually in the presence of predisposing factors. We report a case of amiodarone-induced TdP after long-term administration of a low dose of oral amiodarone in the absence of predisposing factors.

BACKGROUND
The occurrence of atrial fibrillation after ablation of atrial flutter is clinically important. We investigated variables predicting this evolution in ablated patients without a previous atrial fibrillation history. MATERIALS AND METHODS: Thirty-six patients (Male=28) who were diagnosed as atrial flutter without previous atrial fibrillation history were enrolled in this study. Group 1 (n=11) was defined as those who developed atrial fibrillation after atrial flutter ablation during 1 year follow-up. Group 2 (n=25) was defined as those who has not occurred atrial fibrillation during same follow-up term. Echocardiogram was performed to all patients. We measured left atrial size, left ventricle end diastolic and systolic dimension, ejection fraction and left atrial volume index before and after ablation of atrial flutter. The differences of each variables were compared and analyzed between two groups. RESULTS: The preablation left ventricular ejection fraction (preLVEF) and postablation left ventricular ejection fraction (postLVEF) are 54+/-14%, 56+/-13% in group 1 and 47+/-16%, 52+/-13% in group 2. The differences between each two groups are statistically insignificant (2.2+/-1.5 in group 1 vs 5.4+/-9.8 in group 2, p=0.53). The preablation left atrial size (preLA) and postablation left atrial size (postLA) are 40+/-4 mm, 41+/-4 mm in group1 and 44+/-8 mm, 41+/-4 mm in group 2. The atrial sizes of both groups were increased but, the differences of left atrial size between two groups before and after flutter ablation were statistically insignificant (0.6+/-0.9mm in group 1 vs -3.8+/-7.4 mm in group 2, p=0.149). The left atrial volume index before flutter ablation was significantly reduced in group 1 than group 2 (32+/-10 mm3/m2, 35+/-10 mm3/m2 in group 1 and 32+/-10 mm3/m2, 29+/-8 mm3/m2 in group 2, p<0.05). CONCLUSION: The difference between left atrial volume index before and after atrial flutter ablation is the robust predictor of occurrence of atrial fibrillation after atrial flutter ablation without previous atrial fibrillation.

AbstractAbstract PDF
Glycogen storage diseases are a heterogeneous group of metabolic disorder affecting multiple organ system: liver, skeletal muscle, heart and brain. Clinical features include: short status, hepatomegaly, hypoglycemia, dyslipidemia and rare involvement of the myocardium except in the case of type III, glycogen storage diseases with hypertrophic cardiomyopathy in adult, which is extremely rare. We treated a case of hypertrophic cardiomyopathy with hepatomegaly that was unknown etiology. The patient was diagnosed as having glycogen storage disease. This 46-year old women was transferred with dyspnea on exertion and abnormal LFTs. She was diagnosed with hypertrophic cardiomyopathy by echocardiography but there was no specific cause for hypertrophic cardiomyopathy. A liver biopsy was performed. The result showed glycogen storage disease possible type III, IV or IX. In conclusion, patients with hypertrophic cardiomyopathy of unknown etiology and abnormal LFTs should be evaluated for glycogen storage disease.
