We report a case in which permanent pacemaker implantation using a conventional subclavian approach on the throwing side of an avid softball player resulted in complete transection of the ventricular lead and severe damage to the atrial lead. The site of the lead fracture suggested that both leads were crushed between the clavicle and the first rib as a result of the frequent and repetitive arm movement. This case illustrates the importance of the selection of the correct approach for permanent pacing lead insertion.

Deep learning model for identifying acute heart failure patients using electrocardiography in the emergency room.

Background: Acute heart failure (AHF) poses significant diagnostic challenges in the emergency room (ER) because of its varied clinical presentation and limitations of traditional diagnostic methods. This study aimed to develop and evaluate a deep-learning model using electrocardiogram (ECG) data to enhance AHF identification in the ER.
Methods: In this retrospective cohort study, we analyzed the ECG data of 19,285 patients who visited ERs of three hospitals between 2016 and 2020; 9,119 with available left ventricular ejection fraction and N-terminal prohormone of brain natriuretic peptide level data and who were diagnosed with AHF were included in the study.
Outcomes of catheter ablation in cardiac sarcoidosis patients with ventricular tachycardia: a propensity score-matched retrospective analysis.

Background: Ventricular tachycardia (VT) in patients with cardiac sarcoidosis (CS) can lead to sudden cardiac death. The role of ventricular tachycardia ablation (VTA) in CS has been investigated in a few small, single-center, and larger observational studies, but the evidence still needs to be provided. This study aimed to investigate the clinical outcomes of VTA in patients with CS admitted with a diagnosis of VT.

Central sleep apnea (CSA), a rare polysomnographic finding in the general population, is prevalent in certain cardiovascular conditions including systolic and diastolic left ventricular dysfunction, atrial fibrillation, coronary artery disease, carotid artery stenosis, stroke and use of certain cardiac-related medications. Polysomnographic findings of CSA with adverse cardiovascular impacts include nocturnal hypoxemia and arousals, which can lead to increased sympathetic activity both at night and in the daytime. Among cardiovascular diseases, CSA is most prevalent in patients with left ventricular systolic dysfunction; a large study of more than 900 treated patients has shown a dose dependent relationship between nocturnal desaturation and mortality.

Introduction: In patients with symptomatic, refractory atrial fibrillation the ablate and pace (A&P) strategy (pacemaker implantation followed by atrio-ventricular junction ablation (AVJA)) is superior to medical therapy in improving quality of life and prognosis. Despite its well-proven benefits, this invasive therapeutic option is still underutilized in clinical practice. The choice of pacing modality (right ventricular pacing, biventricular pacing, BVP, or conduction system pacing, CSP) is crucial and can have significant clinical implications.

Aims: Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment outcomes. However, the response varies across different populations, and their use may lead to life-threatening cardiovascular (CV) events. While pre-treatment reduced left ventricular ejection fraction (LVEF) is considered a marker for high-risk cardiotoxicity and a contraindication for anthracycline and HER2-targeted therapies, there is limited evidence on the safety and efficacy of ICIs therapy in patients presenting with pre-treatment reduced LVEF.
