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

open access: yes, 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 ...

Cardiovascular Challenges in Chronic Lymphocytic Leukemia (CLL) Patients Undergoing Bruton Tyrosine Kinase (BTK) Inhibitor Therapy

open access: yesEuropean Journal of Haematology, EarlyView.
ABSTRACT Background/Objectives Bruton tyrosine kinase inhibitors (BTKis) have revolutionized treatment for chronic lymphocytic leukemia (CLL), but cardiovascular (CV) toxicities pose significant challenges. Second‐generation BTKis offer improved target specificity, yet CV risks persist.

Lateralizing value of interictal epileptiform discharges and other parameters in hypothalamic hamartoma

open access: yesEpilepsia, Volume 66, Issue 3, Page 662-673, March 2025.
Abstract Objective Hypothalamic hamartomas (HHs) are associated with pharmacoresistant epilepsy. Stereotactic radiofrequency thermocoagulation (SRT) shows promise as a disconnecting intervention. Although magnetic resonance imaging (MRI) is typically used to determine the attachment and intervention side, it presents challenges in cases of bilaterally ...

Rare dysfunctional SCN2A variants are associated with malformation of cortical development

open access: yesEpilepsia, Volume 66, Issue 3, Page 914-928, March 2025.
Abstract Objective SCN2A encodes the voltage‐gated sodium (Na+) channel α subunit NaV1.2, which is important for the generation and forward and back propagation of action potentials in neurons. Genetic variants in SCN2A are associated with a spectrum of neurodevelopmental disorders.

Premature ventricular contractions in normal children.

open access: yesThe Turkish journal of pediatrics, 2008
Premature ventricular contractions (PVCs) are frequently seen in children with normal cardiac findings. The purpose of this study was to evaluate the characteristics and the prognosis of PVCs in children with normal heart. This study included 149 children with PVC who did not have systemic or cardiac disease. Their median age at diagnosis was 10 years (

In vivo modeling of lethal congenital contracture syndrome 1 suggests pathomechanisms in cellular stress responses

open access: yesThe FEBS Journal, EarlyView.
Gle1 knockout mice fail to segregate cell lineages at the blastocyst stage, resulting in very early embryonic lethality. Gle1 knock‐in (KI) mice harboring a pathogenic variant giving rise to lethal congenital contracture syndrome 1 show both known and novel innervation defects, supportive of multiorgan pathology in human fetuses.
