BACKGROUND AND OBJECTIVES The sinus venosus (SV) is not a well known source of atrial tachycardia (AT), but it can harbor AT during catheter ablation of atrial fibrillation (AF). SUBJECTS AND METHODS A total of 1223 patients who underwent catheter ablation for AF were reviewed. Electrophysiological and electrocardiographic characteristics and outcomes(More)
Coronary artery fistulas (CAFs) are one of the most rare cardiac anomalies. Some patients with CAF may suffer from ischemic chest pain that originates from combined significant coronary artery spasm (CAS). Spontaneous regression of CAF has been reported in a few cases, almost all of which were infants. We report an adult patient who presented with ischemic(More)
Percutaneous recanalization of chronic total occlusions (CTOs) in peripheral arteries, especially TASC D classification including the distal aorta and both iliac arteries is still technically challenging. The conventional technique using standard guidewires and catheters guided by computed tomography and angiography can achieve a limited initial success,(More)
We report a case about a 27-year-old healthy young male who developed syncope during exercise, which was subsequently identified to be attributable to non-sustained polymorphic ventricular tachycardia (VT). Occurrence of polymorphic VT was neither related to a prolonged QT interval nor a fixed short coupling interval. Standard examinations including(More)
Aortic coarctation is a correctable hypertensive disease. For safety reasons and due to the invasiveness of surgical techniques, percutaneous interventions have become drastically more popular in recent times. In elderly patients with aortic coarctation who are at risk of an aortic wall aneurysm and rupture, covered stents are preferred but in younger(More)
There is no current guideline for percutaneous coronary angioplasty in stenotic ectatic coronary arteries because of the heterogeneity of the coronary artery morphology. We report two successful angioplasty cases in coronary artery ectasia with different clinical scenarios. One case showed atherosclerotic stenosis in the ectatic portion of the right(More)
