Cardiac tamponade is a rare but fatal complication of catheter ablation. We are reporting a case of a 73-year-old male with ventricular tachycardia (VT) storm undergoing urgent VT ablation, who was later found to have right ventricle (RV) perforation-an unusual site for catheter ablation complication. The patient underwent isochronal late activation mapping (ILAM)-based ablation and elimination of local abnormal ventricular activities (LAVA).

Background: Fatal arrhythmic events (FAEs), such as sudden cardiac death (SCD) and fatal ventricular arrhythmias, are a devastating complication in patients with coronary artery disease (CAD). Therefore, in this study we aimed to assess the incidence of FAEs in more recent Japanese patients with CAD and to examine whether risk stratification of FAEs can still be feasible using the left ventricular ejection fraction (LVEF).

Methods And Results: In the CREDO Kyoto PCI/CABG registry cohorts-2 and -3, there were 25,843 patients with LVEF data who received a first coronary revascularization (LVEF ≤35% group: N=1,671, 35%45%: N=21,503).

Department of Physiology, University of Kentucky, Lexington, KY, USA; Department of Internal Medicine, University of Kentucky, Lexington, KY, USA. Electronic address:

Cardiologists have analyzed daily patterns in the incidence of sudden cardiac death to identify environmental, behavioral, and physiological factors that trigger fatal arrhythmias. Recent studies have indicated an overall increase in sudden cardiac arrest during daytime hours when the frequency of arrhythmogenic triggers is highest. The risk of fatal arrhythmias arises from the interaction between these triggers-such as elevated sympathetic signaling, catecholamine levels, heart rate, afterload, and platelet aggregation-and the heart's susceptibility (myocardial substrate) to them.

Purpose: To investigate image quality and agreement of derived cardiac function parameters in a novel joint image reconstruction and segmentation approach based on disentangled representation learning, enabling real-time cardiac cine imaging during free-breathing.

Methods: A multi-tasking neural network architecture, incorporating disentangled representation learning, was trained using simulated examinations based on data from a public repository along with MR scans specifically acquired for model development. An exploratory feasibility study evaluated the method on undersampled real-time acquisitions using an in-house developed spiral bSSFP pulse sequence in eight healthy participants and five patients with intermittent atrial fibrillation.

Atrial fibrillation (AF) is the most common cardiac arrhythmia and pulmonary vein isolation (PVI) by percutaneous transcatheter ablation is its pivotal treatment. Nowadays, several techniques using different energy sources are used, such as radiofrequency (RF), cryoablation and laser ablation. A new technology that combines the strengths of different techniques has been developed, in particular having both the speed of one-shot techniques and the selectivity and precision of point-by-point RF: the RF balloon (RFB).

ITFG2 is an intracellular protein known to modulate the immune response of T-cells. Our previous investigation revealed that ITFG2 specifically targets ATP5b to regulate ATP energy metabolism and maintain mitochondrial function, thereby protecting the heart from ischemic injury. However, the role of ITFG2 in ischemic ventricular arrhythmias and its underlying mechanisms have not been previously reported.

Introduction: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia worldwide. Although catheter ablation is the most efficacious therapy, relapses occur frequently (30%) in the first year after ablation. Novel biomarkers of recurrence are needed for a better prediction of recurrence and management of AF.

Background: Atrial fibrillation (AF) is the most prevalent arrhythmia encountered in clinical practice. Triglyceride glucose index (Tyg), a convenient evaluation variable for insulin resistance, has shown associations with adverse cardiovascular outcomes. However, studies on the Tyg index's predictive value for adverse prognosis in patients with AF without diabetes are lacking.

Introduction: Electrophysiologic (EP) procedures are typically performed via the femoral venous system, but in some patients, the inferior vena cava (IVC) is unavailable. The hepatic vein has emerged as a viable alternative to femoral access, providing an inferior route that accommodates large sheaths required for better catheter manipulation. Although the percutaneous transhepatic approach has been used successfully in the pediatric population, its use in adults is scarce, with a complication rate of approximately 5%.

Background: People with subclinical atrial fibrillation are at increased risk of stroke, albeit to a lesser extent than those with clinical atrial fibrillation, leading to an ongoing debate regarding the benefit of anticoagulation in these individuals. In the ARTESiA trial, the direct-acting oral anticoagulant apixaban reduced stroke or systemic embolism compared with aspirin in people with subclinical atrial fibrillation, but the risk of major bleeding was increased with apixaban. In a prespecified subgroup analysis of ARTESiA, we tested the hypothesis that people with subclinical atrial fibrillation and a history of stroke or transient ischaemic attack, who are known to have an increased risk of recurrent stroke, would show a greater benefit from oral anticoagulation for secondary stroke prevention compared with those without a history of stroke or transient ischaemic attack.

Background: Dravet syndrome (DS) is a severe developmental and epileptic encephalopathy associated with loss-of-function variants in the SCN1A gene. Although predominantly expressed in the central nervous system, SCN1A is also expressed in the heart, suggesting a potential link between neuronal and cardiac channelopathies. Additionally, DS carries a high risk of sudden unexpected death in epilepsy (SUDEP).
