Background: Paroxysmal atrial fibrillation (PAF) significantly impacts patients' lives, contributing to morbidity, reduced quality of life (QoL), and psychological distress. Conventional treatment approaches primarily focus on rhythm control through pharmacologic therapy, often overlooking the patient's holistic well-being.

Hypothesis: Cognitive behavioral therapy (CBT), a well-established intervention for modifying dysfunctional thoughts and behaviors, may provide a beneficial nonpharmacological approach to improving QoL in symptomatic PAF patients.

Background: High-frequency, low-tidal volume (HFLTV) ventilation increases the efficacy and efficiency of radiofrequency catheter ablation (RFCA) of paroxysmal atrial fibrillation. Whether those benefits can be extrapolated to RFCA of persistent atrial fibrillation (PeAF) is undetermined.

Objective: The purpose of this study was to evaluate whether using HFLTV ventilation during RFCA in patients with PeAF is associated with improved procedural and long-term clinical outcomes compared to standard ventilation (SV).

Sudden cardiac death (SCD) is one of the leading causes of death worldwide, usually involving young people. SCD remains a critical public health problem accounting for 185,000-450,000 deaths annually, representing around 7%-18% of all deaths globally. As per evidence, ∼2%-54% of sudden unexpected deaths in people under the age of 35 years fail to show evidence of structural cardiac abnormalities at autopsy, making ion channelopathies the probable causes in such cases.

Provide a brief summary of your article (100-150 words; no references or figures/tables). The synopsis appears only in the table of contents and is often used by indexing services such as PubMed. Genetic arrhythmia syndromes are rare, yet harbor the potential for highly consequential, often unpredictable arrhythmias or sudden death events.

Coronary subclavian steal syndrome (CSSS) is a complication incurred after coronary artery bypass grafting (CABG), characterized by retrograde blood flow through the left internal mammary artery (LIMA) graft to the left subclavian artery (SCA) distal to a SCA stenosis, thereby compromising myocardial perfusion from the LIMA despite its patency. We present a 40-year-old female with a history of triple-vessel CABG who presented with crescendo angina, notably when elevating her arms above her head. Atypical angina related to arm activity following successful LIMA bypass should prompt angiography directed to the left SCA, as well as to the LIMA graft.

Dysphagia lusoria is difficulty swallowing as a result of extrinsic esophageal compression by an aberrant right subclavian artery (ARSA). We present the case of a 59-year-old patient with ARSA and history of chronic dysphagia. Vascular decompressive surgery was performed, but it failed to resolve his symptoms.
