Spontaneous medialstinal emphysema (pneumomediastinum) and pneumopericardium may be defined as the presence of free air or gas in the mediastinal structures and in the pericardial sac without an apparent precipitating cause. It most frequently occurs in young healthy adults without serious underlying pulmonary disease. Although pneumomediastinum and(More)
BACKGROUND AND OBJECTIVES Thrombospondin-1 (TSP-1) is associated with atherosclerosis in animals with diabetes mellitus (DM). But, no study has investigated the role of TSP-1 in human atherosclerosis. This study investigated the relationship among plasma TSP-1 concentration, DM, and coronary artery disease (CAD). SUBJECTS AND METHODS The study involved(More)
Dysphagia aortica is difficulty in swallowing caused by extrinsic compression of the esophagus due to an ectatic, tortuous, or aneurysmatic atherosclerotic thoracic aorta. This condition is very uncommon, and it is usually associated with old age, women with short stature, hypertension, and kyphosis. We report herein a case involving a patient with(More)
BACKGROUND AND OBJECTIVES We aimed to investigate whether a large-sized Lasso catheter could increase the success rate of immediate complete pulmonary vein (PV) antral isolation and improve the outcome of catheter ablation in atrial fibrillation (AF) patients. SUBJECTS AND METHODS This study included 107 consecutive patients (67 males, mean age: 57.8±9.7(More)
Pacemaker lead infection is a rare but a dangerous complication. Diagnosis can usually be established by the clinical picture and blood cultures. Transesophageal two dimensional echocardiography might be crucial in the diagnosis by visualizing pacing lead vegetations. Medical treatment alone is rarely successful, and several studies have suggested the(More)
BACKGROUND AND OBJECTIVES While pulmonary vein isolation (PVI) is an effective curative procedure for patients with atrial fibrillation (AF), pulmonary vein (PV) stenosis is a potential complication which may lead to symptoms that are often unrecognized. The aim of this study was to compare differences between ablation sites in pulmonary venous flow (PVF)(More)
BACKGROUND AND OBJECTIVES Little evidence is available on the optimal antithrombotic therapy following percutaneous coronary intervention (PCI) in patients with atrial fibrillation (AF). We investigated the outcomes of antithrombotic treatment strategies in AF patients who underwent PCI. SUBJECTS AND METHODS Three hundred sixty-two patients (68.0% men,(More)
Posteroseptal accessory pathways are often associated with coronary sinus diverticula. These diverticula contain myocardial coats which serve as a bypass tract. We report a 54-year-old woman who underwent radiofrequency (RF) catheter ablation for Wolff-Parkinson-White (WPW) syndrome. The surface electrocardiography (ECG) demonstrated pre-excitation,(More)
BACKGROUND AND OBJECTIVES The number of permanent pacemakers (PPMs) implanted in patients in Japan and Korea differs significantly. We aimed to investigate the differences in decision making processes of implanting a PPM. MATERIALS AND METHODS Our survey included 15 clinical case scenarios based on the 2008 AHA/ACC/HRS guidelines for device-based therapy(More)
Left ventricular hypertrabeculation/noncompaction (LVHT) is an uncommon type of genetic cardiomyopathy characterized by trabeculations and recesses within the ventricular myocardium. LVHT is associated with diastolic or systolic dysfunction, thromboembolic complications, and arrhythmias, including atrial fibrillation, ventricular arrhythmias,(More)
