Bacteremia caused by late-infected pacemaker lead--a case report.

A 73-year-old man with bradycardia and atrial fibrillation underwent implantation of a transvenous pacemaker system on the left anterior chest wall in 1995. Six years later, he was admitted for bacteremia from coagulase-negative Staphylococcus. Repeated treatment employing antibiotic therapy was ineffective. The infected electrode was removed under cardiopulmonary bypass. His electrode had become firmly encased with fibrous tissue within the right ventricle and atrium. It was removed under direct vision during complete cardiac arrest. The postoperative course was uneventful and there has been no recurrence after 1 year.

Radiofrequency catheter ablation of accessory pathway in a patient with Ebstein's anomaly and atrial septal defect--a case report.

The authors report the case of a 57-year-old woman with Ebstein's anomaly and atrial septal defect. She was referred to their hospital for treatment of refractory paroxysmal wide QRS tachycardia. Her 12-leads ECG in sinus rhythm showed ventricular preexcitation of type B Wolff-Parkinson-White syndrome. In a baseline electrophysiological study, a wide QRS tachycardia with right bundle branch block configurations was induced. This tachycardia was orthodromic atrioventricular reciprocating tachycardia with a right inferior accessory pathway. Radiofrequency current was successfully delivered at the inferior site of the atrialized right ventricle. Radiofrequency catheter ablation seems to be useful for supraventricular tachycardia in patients with Ebstein's anomaly and atrial septal defect.

Large saccular aneurysm in a coronary arterial fistula--a case report.

The authors present a case of a large saccular aneurysm in a coronary artery fistula originating from the proximal left anterior descending coronary artery, draining into the main trunk of the pulmonary artery. The diagnosis was made by 3-dimensional computed tomography and coronary arteriography. Congenital coronary artery fistula is not uncommon. With a saccular aneurysm, however, it is very rare. A ruptured aneurysm will induce sudden death if surgical repair is not done.
