Circular mapping catheter entrapment in the mitral valve apparatus: a previously unrecognized complication of focal atrial fibrillation ablation.
Radiofrequency catheter ablation of focal atrial fibrillation triggers within the pulmonary veins is a rapidly developing therapy that relies on both recent technologies and evolving techniques. We describe the entrapment of a circular mapping catheter within the mitral valve apparatus after transseptal catheterization and mapping of the left atrium and pulmonary veins. The occurrence of this previously unreported complication stresses the need for continual monitoring and reporting of adverse effects from new devices and procedures to better inform patients and physicians of the benefits and risks of electrophysiologic interventions.

Successful interventional treatment of an octogenarian presenting with syncope and Ebstein's anomaly of the tricuspid valve.
Syncope is a frequent occurrence in the elderly and cardiac causes are common. Therefore, accurate diagnosis is essential since specific treatments are often required. We present an 85-year-old woman with recurrent syncope secondary to sinus node reentrant tachycardia (SNRT), which was successfully treated by radiofrequency ablation. This is the first reported description of SNRT and its successful treatment in Ebstein's anomaly. Atrial arrhythmias and accessory atrioventricular bypass pathways are common in Ebstein's anomaly and are briefly discussed. Our patient is alive at age 87, which is exceptional for Ebstein's anomaly.
