Brugada phenocopy in diabetic ketoacidosis, the importance of the diagnostic approach

Abstract Brugada phenocopies (BrP) are clinical entities that present with identical ECG patterns to those of true Brugada Syndrome (BrS) but are elicited by various other clinical circumstances. Our manuscript shows an interesting case of a type-1 Class A BrP in a young patient with diabetic ketoacidosis and hyperkalemia.

Use of wearable cardioverter‐defibrillator in association with catheter ablation for atrial fibrillation‐related tachycardiomyopathy

Implantable cardioverter‐defibrillator (ICD) implantation is not indicated in patients with potentially transient or reversible causes of sudden cardiac death (SCD). Wearable cardioverter‐defibrillator (WCD) is increasingly used for SCD prevention in patients who are temporary at high risk of ventricular arrhythmia. Hereby, we describe a case of tachycardiomyopathy successfully managed with ablation and WCD backup. Implantable cardioverter‐defibrillators are a Class I indication by American College of Cardiology/American Heart Association/Heart Rhythm Society guidelines to prevent SCD in patients with nonischemic dilated cardiomyopathy, New York Heart Association (NYHA) functional class II …

Phrenic nerve displacement by intrapericardial balloon inflation during epicardial ablation of ventricular tachycardia: Four case reports

BACKGROUND Phrenic nerve (PN) injury is one of the recognized possible complications following epicardial ablation of ventricular tachycardia (VT). High-output pacing is a widely used maneuver to establish a relationship between the PN and the ablation catheter tip. An absence of PN capture is usually considered an indication that it is safe to ablate, and that successful ablation may be performed at adjacent sites. However, PN capture may impact the procedural outcome. Only a few cases have been reported in the literature that avoid PN injury by using different techniques. CASE SUMMARY Three patients with a previous history of myocarditis and one patient with ischemic cardiomyopathy underw…

Pacing ventricolare destro: una risorsa o una minaccia?

Early after the beginning of the pacemaker era, endocardial right ventricular apex has been the most extensively used site for cardiac pacing because it was easily accessible and reliable in a long-term perspective. However many data have demonstrated that this kind of pacing is suboptimal from a physiologic point of view because it causes several adverse effects such as altered ventricular contraction geometry, mitral regurgitation, perfusion alterations and interference with myocardial ion channels which determine a worsening of left ventricular function. Several strategies have been proposed to solve these problems (alternative pacing sites, specific algorithms able to reduce the percent…

Role of Rate Control and Regularization Through Pacing in Patients With Chronic Atrial Fibrillation and Preserved Ventricular Function: The VRR Study

Aim: High heart rates in chronic atrial fibrillation (CAF) is one of the factors responsible for hemodynamic alterations and may lead to tachycardiomyopathies. The ventricular rate regulation (VRR) study evaluates the effect of ventricular rate regularization in CAF patients with preserved ventricular function, marked ventricular rate variability, and indications for pacemaker (PM) implantation owing to symptomatic pauses. Rate regularization was achieved using VRR algorithm (INSIGNIA® pacemakers, Guidant Corp., St. Paul, MN, USA). Methods: One month after PM implantation, 58 patients followed two 3-month crossover periods (VRR-OFF; VRR-ON) in which the VRR algorithm was randomized and comp…
