AbstractAbstract PDF
Left main coronary artery (LMCA) thrombosis is rare and the cause should be determined. A previously healthy young man presented with severe chest pain and dyspnea. The electrocardiogram showed typical ST-segment elevation myocardial infarction with clinical instability. Emergency coronary angiography revealed complete LMCA occlusion by thrombosis. After reperfusion, the patient was admitted to the cardiac care unit. He was diagnosed with hemolytic anemia and tested positive for antinuclear antibodies. Systemic lupus erythematosus (SLE) and LMCA disease due to systemic thrombosis were diagnosed. Steroids were started and the patient was discharged without complications. We report this rare case of LMCA thrombosis as an initial presentation of SLE.

AbstractAbstract PDF
Transcatheter aortic valve implantation (TAVI) has evolved from a challenging intervention to a standardized, simple, and streamlined procedure with over 350,000 procedures performed in over 70 countries. It is now a novel alternative to surgical aortic valve replacement in patients with intermediate surgical risk and its indications have been expanded to cohorts with bicuspid aortic valves, low surgical risk, and younger age and fewer comorbidities. Attention should be paid to further reducing remaining complications, such as paravalvular aortic regurgitation, conduction abnormalities, cardiac tamponade, and stroke. The aim of this review is to provide an overview on the rapidly changing field of TAVI treatment and to explore past achievements, current issues, and future perspectives of this treatment modality.

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.
