Cardiovascular toxicity from immune checkpoint inhibitor therapy: an inflammatory continuum

British Journal of Pharmacology, EarlyView.
Immune checkpoint inhibitor (ICI) therapy has markedly improved outcomes in advanced malignancies but has also revealed a distinct spectrum of cardiovascular immune‐related adverse events. Myocarditis represents the most severe manifestation, while non‐inflammatory left ventricular dysfunction and vascular inflammation have emerged as additional ...

Modern mapping and ablation of idiopathic outflow tract ventricular arrhythmias

Reviews in Cardiovascular Medicine, 2022
Outflow tract (OT) premature ventricular complexes (PVCs) are being recognized as a common and often troubling, clinical electrocardiographic finding. The OT areas consist of the Right Ventricular Outflow Tract (RVOT), the Left Ventricular Outflow Tract (LVOT), the Aortomitral Continuity (AMC), the aortic cusps and the Left Ventricular (LV) summit.

Idiopathic Epicardial Ventricular Arrhythmias: Diagnosis and Ablation Technique from the Aortic Sinus of Valsalva [PDF]

, 2005
Idiopathic outflow tract arrhythmias (ventricular tachycardias or symptomatic premature ventricular contractions; OT-VT/PVCs) can originate from the left ventricular (LV) epicardium (Epi-VT/PVCs), and radiofrequency (RF) energy applications from the ...

Cisterna Chyli Dilation Is a Risk Factor for Liver Nodules and Hepatocellular Carcinoma in Fontan‐Associated Liver Disease: Pathophysiological Role of Lymphatic Dysfunction

Hepatology Research, EarlyView.
ABSTRACT Aim In Fontan‐associated liver disease (FALD), chronic congestion often confounds conventional fibrosis markers, complicating surveillance for hepatocellular carcinoma (HCC). Although lymphatic dysfunction is fundamental to Fontan physiology, its contribution to hepatocarcinogenesis remains unclear.

Ablation of idiopathic ventricular arrhythmias from the right ventricular apex

Heart Rhythm
Idiopathic ventricular arrhythmias (VAs) from the right ventricle (RV) are well-described, but limited data exist regarding those from the RV apex.The purpose of this study was to define the electrocardiographic (ECG) characteristics and ablation outcomes of RV apical VAs, including premature ventricular contractions (PVCs) and ventricular tachycardia ...

Idiopathic Ventricular Arrhythmias Originating From the Left Ventricular Summit [PDF]

Circulation: Arrhythmia and Electrophysiology, 2010
Background— The summit of the left ventricle (LV) is the most superior portion of the epicardial LV bounded by an arc from the left anterior descending coronary artery, superior to the first septal perforating branch to the left circumflex coronary artery.

Catheter ablation of ventricular tachycardia via the coronary veins

Indian Pacing and Electrophysiology Journal
Ventricular arrhythmias, either idiopathic or those associated with organic heart diseases, may originate from the epicardial side of the ventricular myocardium. Therefore, mapping and ablation via the coronary venous system offers a convenient, feasible,

Large Language Model‐Based Localization of Premature Ventricular Contraction Origins: A Retrospective Diagnostic Accuracy Study

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Accurate localization of premature ventricular contraction (PVC) origin from 12‐lead electrocardiography (ECG) is important for procedural planning in catheter ablation. Although convolutional neural network (CNN)‐based models have shown promising diagnostic performance, they require task‐specific training and remain limited in ...

Clinical Outcomes After Catheter Ablation in Patients With Structural Heart Disease and Ventricular Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction In patients with ischemic cardiomyopathy (ICM), recurrent VF may be treated with catheter ablation by targeting triggering premature ventricular complexes (PVCs) and/or ventricular scar homogenization. Data on optimal ablation strategies in patients with non‐ischemic cardiomyopathy (NICM) remain limited.
