Temporary Percutaneous Left Ventricular Support for Ablation of Untolerated Ventricular Tachycardias

Temporary percutaneous left ventricular support for ablation of untolerated ventricular tachycardias: is it worth the trouble?

Left Ventricular Outflow Tract Tachycardias

Left ventricular outflow tract tachycardia (LVOT-VT) is an uncommon type of idiopathic left ventricular tachycardia (ILVT) thought to be due to cyclic adenosine mono phosphate (cAMP) mediated triggered activity. The arrhythmia can be terminated pharmacologically with calcium channel blockers or beta-blockers [1]. LVOT-VT can arise above or below the coronary cusps and the former variety can als...

Catheter Ablation of Idiopathic Premature Ventricular Contractions and Ventricular Tachycardias Originating from Right Ventricular Septum

BACKGROUND Idiopathic premature ventricular contractions (PVCs) and ventricular tachycardias (IVTs) originating from the subtricuspid septum and near the His bundle have been reported. However, little is known about the prevalence, distribution, electrocardiographic characteristics and the efficacy of radiofrequency catheter ablation (RFCA) for the ventricular arrhythmias arising from the right...
