Late elimination of challenging idiopathic ventricular arrhythmias originating from left ventricular summit by anatomical ablation.

Indian Pacing Electrophysiol J 2019 Feb 26. Epub 2019 Feb 26.

Ankara University, Cardiology Department, Ankara, Turkiye.

Ablation of premature ventricular complexes (PVCs) originating from left ventricular outflow tract (LVOT)/left ventricular summit (LVS) is challenging with considerable rate of failure. Recently, in a novel approach to ablation of these arrythmias, application of radiofrequency energy to anatomically opposite sites of presumed origin of arrythmia, has been associated with moderate procedure success. Although late elimination of PVCs that are persistent following an ablation procedure has been previously reported, this observation has not been studied sufficiently. Read More

The role of the Purkinje network in premature ventricular complex-triggered ventricular fibrillation.

J Interv Card Electrophysiol 2018 Aug 31;52(3):375-383. Epub 2018 Jul 31.

Texas Cardiac Arrhythmia Institute, St. David's Medical Center, 3000 N. IH-35, Suite 720, Austin, TX, 78705, USA.

The Purkinje network (PN) is the distal part of the ventricular conduction system, which has shown to play a central role in the pathophysiology of ventricular fibrillation (VF). Abnormal automaticity and triggered activity are commonly seen in the PN, and the resulting premature ventricular complexes (PVCs) are frequently recognized as triggers of this life-threatening arrhythmia. Catheter ablation targeting PN-related PVCs can be successfully performed in patients with medically refractory VF in a variety of arrhythmic substrates. Read More

Ventricular Arrhythmias Underlie Sudden Death in Rats With Heart Failure and Preserved Ejection Fraction.

Circ Arrhythm Electrophysiol 2018 Aug;11(8):e006452

Smidt Heart Institute, Cedars-Sinai Medical Center, Los Angeles, CA.

Background: Heart failure (HF) with preserved ejection fraction (HFpEF) is increasingly common clinically, now rivaling or exceeding HF with reduced ejection fraction . Sudden death is the leading mode of exodus in patients with HFpEF, but the underlying causes are largely unknown. Using ambulatory recordings in a rat model, we test the hypothesis that ventricular arrhythmias (VA) underlie sudden death in HFpEF. Read More

Coupling interval variability: A new diagnostic method for distinguishing left from right ventricular outflow tract origin in idiopathic outflow tract premature ventricular contractions patients with precordial R/S transition at lead V3.

Int J Cardiol 2018 Oct 9;269:126-132. Epub 2018 Jul 9.

Department of Cardiology, The Second Xiangya Hospital of Central South University, Changsha City, Hunan Province 410011, China.

Background: To distinguish left ventricular outflow tract (LVOT) from right ventricular outflow tract (RVOT) origin in idiopathic outflow tract premature ventricular contractions (IOT-PVCs) patients with precordial R/S transition at lead V3 is still a challenge. We sought to develop a new electrocardiography (ECG) method for distinguishing LVOT from RVOT origin in IOT-PVCs patients with precordial R/S transition at lead V3.

Methods: We analyzed the surface 12-lead ECG characteristics and the difference of coupling interval variability (CIV) of PVCs between distinct origin sites in a retrospective cohort of IOT-PVCs patients with precordial R/S transition at lead V3 who underwent successful radiofrequency catheter ablation (RFCA) to develop a new diagnostic method, then validated it in a prospective cohort.

Premature Ventricular Complex-induced Cardiomyopathy.

Arrhythm Electrophysiol Rev 2018 Jun;7(2):128-134

Royal Papworth Hospital NHS Foundation Trust, Cambridge University Health Partners Cambridge, UK.

Premature ventricular complex-induced cardiomyopathy is a potentially reversible condition in which left ventricular dysfunction is induced by the occurrence of frequent premature ventricular complexes (PVCs). Various cellular and extracellular mechanisms and risk factors for developing cardiomyopathy in this context have been suggested but the exact pathophysiological mechanism remains unclear. The suppression of PVCs is usually indicated in symptomatic patients with frequent PVCs and also those with left ventricular dysfunction. Read More
