Left pulmonary cusp ablation of refractory ventricular arrhythmia originating from the inaccessible summit

A 39-year-old female patient who had undergone two extensive radiofrequency (RF) catheter ablations of premature ventricular complexes (PVC) originating from the inaccessible left ventricular summit (LVS) was referred for a third procedure. Mapping of the anterior interventricular vein (AIV) performed by using a steerable catheter confirmed the earliest activation of the PVC in the inaccessible area of the LVS (Figure). Any RF ablation at that earliest site was impossible to use due to the direct proximity of the LAD. With reversed U-shaped technique, a second regular 4 mm ablation catheter (AC) showed very similar PVC activation in the left pulmonary cusp (LPC). A low-power application (21 W, total time of 90 s) delivered from the non-irrigated 4 mm catheter led to immediate elimination of the PVC with no recurrence in the follow-up.

AbstractIntroductionLeft bundle branch area pacing (LBBAP) has recently been reported to be a new physiological pacing strategy with clinical feasibility and safety. The present study aims to investigate depolarization ‐repolarization measures including QT interval, QT dispersion (QTD) and Tpeak ‐end interval (TpTe) in this novel LBBAP strategy.Methods and Results131 pacing ‐indicated patients were prospectively enrolled and randomized to LBBAP group (n=66) and right ventricular septum pacing (RVSP) group (n=65). LBBAP was successfully achieved in 61 subjects with stable lead performance and comparable complications ...

AbstractPurpose of ReviewNon-ischaemic dilated cardiomyopathy (DCM) occurs in 1 in 2500 individuals in the general population and is associated with considerable morbidity and mortality. Studies involving large numbers of unselected DCM patients have led to consensus guidelines recommending implantable cardioverter-defibrillator (ICD) implantation for protection against sudden cardiac death (SCD) in those with LVEF ≤35%. The purpose of this article is to review the literature for other potential markers including serological, electrocardiographic, echocardiographic, cardiac magnetic resonance, ambulatory ECG and genetic...

ConclusionsThis report highlighted the fact that optimum management of VF is still lacking and necessitates more studies. The appropriate effective dose of potassium replacement during VF might need to be reconsidered in patients with persistent VF.

AbstractCatheter ablation is a  well-recognized treatment for a number of cardiac arrhythmias. Initially used to treat supraventricular tachycardia, this technique is now also widely used to treat ventricular arrhythmia and atrial fibrillation. This review aims to describe all the possible types of complication related to this i nvasive procedure. Definitions according to the current guidelines are provided, as are some details on the frequency of complications and how to diagnose and treat them appropriately. Finally, each section of the review provides guidance on how to prevent the complications associated with catheter ablation.

The residual risk of ventricular arrhythmia (VA) after cardiac resynchronization therapy (CRT) implantation in patients with non-ischemic cardiomyopathy (NICM) remains difficult to evaluate. The impact of left ventricular (LV) wall thickness (WT) measured using computed tomography (CT) on the occurrence of VA after CRT implantation has never been investigated. In this pilot study, we examined the association of LVWT and the occurrence of VA in NICM patients receiving CRT. Thirty three patients with NICM scheduled for CRT underwent pre-procedural CT.
