INTRODUCTION: Treating ventricular tachycardia (VT) in patients with cardiac sarcoidosis (CS) is challenging as patients present in different phase of the disease (inflammatory, scar or sometimes both). A customized approach to treatment is required for better outcomes. We describe our experience in the management of VT in CS based on the phase of the disease. METHODS AND RESULTS: Patients were considered to have myocardial inflammation if there was an increased myocardial (18) Fluoro Deoxy Glucose (FDG) uptake in PET-CT scan of the chest (n=14)...

Catheter ablation is a recommended therapy option for ventricular tachycardia (VT). The antegrade transseptal approach for targeting VT with left ventricular origin is feasible with the high-resolution basket catheter. High-resolution mapping offers the potential to quickly acquire detailed voltage and activation maps. This may help to identify the crucial VT-substrate even in patients with huge scar areas and hemodynamically unstable VT.

BACKGROUND: Verapamil-sensitive fascicular ventricular tachycardia (FVT) has been demonstrated to be a reentrant mechanism using the Purkinje network as a part of its reentrant circuit. Although the papillary muscles (PMs) are implicated in arrhythmogenic structure, reentrant FVT originating from the PMs has not been well defined. METHODS AND RESULTS: We studied 13 patients in whom FVT was successfully eliminated by ablation at the posterior PMs (n=8; PPM-FVT) and anterior PMs (n=5; APM-FVT)...

Ventricular tachycardia (VT) in the setting of left ventricular assist device (LVAD) therapy has been well described. We present a case of incessant ventricular tachycardia resulting in severe right ventricular (RV) failure and subsequent left ventricular (LV) cavity obliteration, which in turn diminished the feasibility of initial attempt at VT ablation.

Extracorporeal life support (ECLS) is a very effective bridging therapy in patients with refractory ventricular tachycardia (VT) associated with cardiogenic shock. A moribund patient in extremis, is not amenable to optimization by standard ACC/AHA guidelines. New approaches and novel salvage techniques are necessary to improve outcomes in patients with refractory clinical settings such as malignant ventricular arrhythmias, cardiac arrest, cardiogenic shock and/or pulmonary failure until further management options are explored...

BACKGROUND: Epicardial ablation is often necessary for the treatment of complex arrhythmias refractory to endocardial ablation. Conventional needle access to the pericardial space is considered quite challenging, and it is often associated with several potential complications, particularly inadvertent right ventricular puncture. The novel EpiAccess Needle tip is embedded with a pressure sensor able to report the pressure waveform in real time when used with the EpiAccess System. OBJECTIVE: We evaluated the feasibility and safety of the EpiAccess System by EpiEP, Inc...

PURPOSE: Magnetic resonance imaging (MRI) with late gadolinium enhancement is commonly performed in patients with non-ischemic LV ventricular tachycardia/ventricular premature depolarizations (non-ischemic LV-VT/VPDs) to define VT substrate prior to catheter ablation. We investigated the prevalence of abnormal voltage and VT localized to areas of the myocardium not reported to have late gadolinium enhancement (LGE) on routine pre-procedural MRI and sought to determine if quantitative MRI analysis could reduce this discordance...

The role of catheter ablation in patients with ventricular tachycardia (VT) has evolved over the last two decades into an established treatment option. In patients with idiopathic VT catheter ablation is the gold standard treatment option with high effectiveness and low risk of complications. Due to the high risk of side effects the use of antiarrhythmic drugs is only indicated in exceptional cases. In patients with structural heart diseases, such as ischemic and dilated cardiomyopathy, VT is the most frequent cause of death...

A 63-year-old man with a history of remote inferior myocardial infarction and coronary artery bypass grafting (CABG) underwent catheter ablation of ventricular tachycardia (VT). Epicardial catheter ablation of the VT was successful at the crux of the heart despite limited mapping within the pericardial space due to pericardial adhesion. Percutaneous subxiphoidal pericardial approach is usually impossible in patients with a history of open heart surgery due to pericardial adhesions. This report suggested that epicardial VT arising from the crux of the heart could be successfully treated by catheter ablation via subxiphoidal pericardial approach despite pericardial adhesions complicated by prior CABG...
