Corrigendum to: Preventive Ventricular Tachycardia Ablation in Patients with Ischaemic Cardiomyopathy: Meta-analysis of Randomised Trials
In the article by Tilz et al. entitled “Preventive Ventricular Tachycardia Ablation in Patients With Ischaemic Cardiomyopathy: Meta-analysis of Randomised Trials” (Arrhythmia&Electrophysiology Review 2019;8(3):173 –9.https://doi.org/10.15420/aer.2019.31.3), the following correction should be made:
Discussion Tachycardia is a rapid heart rate that is above normal for age and level of exertion. Tachycardia is common, particularly sinus tachycardia due to normally encountered circumstances such as pain, fever or exercise. It is usually a normal physiologic process but sustained tachycardia often indicates a potentially abnormal underlying cause. Sinus tachycardia has a rapid heart rate with normal P waves and P-R intervals and variations from moment to moment and respiration. Generally it is not over 200 beats/minute. Vagal stimulation can slow the heart rate; this is a gradual slowing, not an abrupt slowing seen in ...
AbstractBackgroundThe prognostic implications of non-sustained ventricular tachycardia (NSVT) and their significance as therapeutic targets in patients without prior sustained ventricular arrhythmias remain undetermined. The aim of this study was to investigate the prognostic significance of asymptomatic NSVT in patients who had primary prevention implantable cardioverter-defibrillator (ICD) implantation due to ischemic or non-ischemic cardiomyopathy (ICM, NICM).MethodsWe enrolled 157 consecutive primary prevention ICD patients without previous appropriate ICD therapy (AIT). Patients were allocated to two groups depending ...
Conclusions: Our data suggest that integrin β1D deficiency represents a novel mechanism underlying the increased risk of ventricular arrhythmias in patients with ARVC. PMID: 32122157 [PubMed - as supplied by publisher]
Successful left coronary cusp cryoablation in an adolescent with premature ventrıcular extrasystoles-associated cardiomyopathy. Turk Kardiyol Dern Ars. 2020 Mar;48(2):171-176 Authors: Ergül Y, Özgür S, Kafalı HC Abstract Ventricular arrhythmias arising from coronary cusps are not uncommon. However, the mapping and ablation of outflow tract ventricular arrhythmias originating from aortic cusps can be challenging. Radiofrequency ablation of this area can cause rare but serious complications. This was a report of a 17-year-old male patient with very frequent, nonsustained ventricular tac...
Hypertrophic cardiomyopathy (HCM) carries an increased risk of sudden death due to ventricular arrhythmias (VA). The implantable defibrillator (ICD) is a well-established therapy to treat VA. Monomorphic ventricular tachycardias (MVT) are frequent in HCM patients and suitable for antitachycardia pacing (ATP) termination.
CONCLUSION: Real-time tracking and beam-gating were successfully applied in this first MRgRA to treat sustained VT. PMID: 32067819 [PubMed - as supplied by publisher]
Ventricular tachycardia (VT) is a life-threatening sequela found in patients with cardiomyopathy.
ConclusionDex conferred anti-arrhythmic effects in the context of ICM via upregulation of Cx43 and suppression of inflammation and fibrosis. The anti-arrhythmic and anti-inflammatory properties of Dex may be mediated by phosphorylation of AMPK and subsequent suppression of NF-κB activation.
Conclusions: Preventive VT ablation before ICD implantation did not reduce mortality or hospitalization for arrhythmia or worsening heart failure during 1 year of follow-up when compared to the deferred ablation strategy.

CONCLUSION: PN injury can occur as one of the complications following epicardial VT ablation procedures, and may prevent successful ablation of these arrhythmias. PN displacement by using large balloon catheters into the epicardial space seems to be feasible and reproducible, avoid procedure-related morbidity, and improve ablation success when performed in selected centers and by experienced operators.
