ReviewVentricular tachycardia in the era of ventricular assist devices.
Sustained ventricular tachycardia (VT) in patients with advanced cardiomyopathy is a potentially life-threatening arrhythmia. Newer treatment strategies have evolved that combine the use of catheter ablation to target the substrate for VT and ventricular assist devices (VADs) to hemodynamically support the failing ventricle. This editorial is targeted to the practicing clinician caring for these difficult patients. The current article reviews the use of percutaneous VADs to support catheter ablation of VT, the use of durable VADs to support the failing heart in patients with recurrent VT, ventricular arrhythmias in patients with durable VADs, and the use of catheter ablation to treat VT in patients with durable VADs.

Case ReportsAblation of incessant left atrial tachycardia without fluoroscopy in a pregnant woman.
Management of symptomatic atrial arrhythmia in pregnancy remains a challenge. In this case report, a pregnant woman with incessant tachycardia underwent successful left atrial ablation. The entire procedure was performed without fluoroscopy. ⋯ Ablation of left atrial tachycardia using ICE and electroanatomical guidance is feasible in pregnant women.

Sudden cardiac arrest: ECG repolarization after resuscitation.
Early repolarization (ERep) abnormalities on electrocardiogram (ECG) are common immediately following cardiac arrest. We characterized and correlated electrocardiographic repolarization abnormalities immediately after cardiac arrest with acute coronary angiography. ⋯ In the context of cardiac resuscitation, an ECG with ST elevation favors acute myocardial infarction, whereas the presence of ERep is a marker of a nonischemic event and future ERep syndrome.

Case ReportsTransient ST elevation after ketamine intoxication: a new cause of acquired brugada ECG pattern.
Brugada Syndrome and Ketamine Overdose. A 31-year-old man was referred for ketamine overdose. He presented initially with transient major Brugada ECG pattern. Complete investigation led to the diagnosis of slowly resolvent toxic myocarditis. Brugada-like ECG was suspected to be caused by the ketamine intoxication in this case.

Comparative StudySafety of implantable pacemakers and cardioverter defibrillators in the magnetic field of a novel remote magnetic navigation system.
Electromagnetic interference with pacemaker and implantable cardioverter defibrillator (ICD) systems may cause temporary or permanent system malfunction of implanted devices. The aim of this study was to evaluate potential interference of a novel magnetic navigation system with implantable rhythm devices. ⋯ Interference of a remote magnetic navigation system (at maximal field strength) with pacemakers and ICDs not connected to leads with antitachycardic detection and therapies turned off is rare. Occurring functional abnormalities could be reprogrammed in our sample. An in vitro study will give information about interference of devices connected to leads.
