Computed tomography validated right ventricular mid-septal lead implantation using right ventricular angiography.

Background: Right ventricular (RV) mid-septal pacing has been proposed as an alternative to RV apical pacing. Fluoroscopic and electrocardiogram criteria are unreliable for predicting the RV mid-septal lead position. This study aimed to define the optimal RV mid-septal pacing site using RV angiography.

Cardiac perforation complicating cardiac electrophysiology procedures: value of angiography and use of a closure device to avoid cardiac surgery.

Background: Computed tomography (CT) is used for the diagnosis of cardiac perforation (CP) although it has significant limitations. We report our experience with angiography to assist in the diagnosis and management of cardiac perforation during electrophysiology procedures.

Methods: Patients with suspected CP after pacemaker lead insertion (temporary = 2, permanent = 2) or during epicardial mapping/ablation (n = 2) were included.

Incidence of drug-induced torsades de pointes with intravenous amiodarone.

Aim: To define the incidence, presentation, and outcomes of drug-induced Torsades de Pointes (TdP) with intravenous (IV) amiodarone.

Methods: From January 2014 to August 2016 a total of 268 patients received IV amiodarone, 142 for ventricular tachycardia, 104 for atrial flutter/fibrillation, and 22 for incessant atrial tachycardia. A uniform dosing of amiodarone to yield 1gm/day was used in all patients.
