Successful Stent Implantation for Aortoiliac Bifurcation Stenosis in a Young Patient with Behcet's Disease

Behcet's disease (BD) is a multisystem vascular inflammatory disease. BD can affect blood vessels of nearly all sizes and types. Arterial involvement is a rare but serious condition in the course of BD. Here, we report a case of stenosis at the iliac artery bifurcation which was treated with percutaneous balloon angioplasty and stent implantation in a 37-year-old patient with BD.

Successful Primary Percutaneous Coronary Intervention for Acute Myocardial Infarction in a Patient with Dextrocardia and Hypertrophic Cardiomyopathy

We report a case of a 69-year-old man presenting with acute right chest pain radiating to the right shoulder. Physical examination revealed a right sided apex beat with a palpable liver on the left side. Reversed normalizing electrocardiogram are presented, allowing for correct diagnosis of an acute anterior myocardial infarction. Dextrocardia with situs inversus is an uncommon congenital condition, the patient also diagnosed hypertrophic cardiomyopathy by two dimensional echocardiography. Successful percutaneous coronary intervention was performed and the patient was discharged after uneventful recovery.

Differing Electrophysiological Effects of Various Antiarrhythmic Drugs on the Cardiac Chamber in Atrial Fibrillation / 대한내과학회지

BACKGROUND/AIMS: Long-term antiarrhythmic drug therapy remains the principal approach for suppressing atrial fibrillation (AF) and maintaining sinus rhythm. In this study, we examined the differing electrophysiological effects of various antiarrhythmic drugs on the cardiac chamber and atrial selectivity in patients with AF. METHODS: We analyzed 134 patients (60.4 +/- 12.5 years, M:F = 1.14:1) who were administered a single antiarrhythmic agent for AF over 6 months: amiodarone (group A), flecainide (group F), or propafenone (group P). The P wave, QRS complex duration and dispersion, and QT interval and its dispersion were evaluated using a standard 12-lead electrocardiogram. RESULTS: There was no significant difference in age, gender ratio, or associated diseases among the three groups. In group A, Pmax, Pmin, P dispersion, QRSmax, QRSmin, and QRS dispersion were shorter than in groups F and P, whereas Pmax/QRSmax was the highest in group A (A = 1.2, F = 0.9, P = 1.0; p < 0.01). QTcmax and QTcmin were longer in group A, whereas QTc dispersion and the QT peak to end (A = 13.3 +/- 11.2, F = 30.7 +/- 24.9, P = 31.8 +/- 21.6; p < 0.01) were shorter in group A than in the other groups. CONCLUSIONS: Amiodarone had a weaker, but more selective, inhibitory effect on intra-atrial conduction, and inhibited ventricular repolarization more effectively and homogenously than flecainide or propafenone. These differing electrophysiological effects may contribute to the superior effectiveness and safety of amiodarone over flecainide or propafenone.
