Spiral twisting of distal (V4) vertebral arteries in an asymptomatic female and its embryological basis.

Intracranial vessels develop early in embryonic life through mutual interaction and integration of aortic arches giving the carotid arteries and intrinsic longitudinal neural system forming the posterior circulation. Due to the relatively short time and faster pace of completion of development, minor absent/persistent segments may give rise to either asymptomatic anatomical variants or hemodynamically significant changes. Intracranial vessels - both anterior carotid and posterior vertebrobasilar systems - are known to have many common anatomical variations like hypoplastic segments (A1 or P1 segments of anterior or posterior cerebral arteries) and persistent carotid-vertebrobasilar anastomotic channels.

Self-reported history of head injury is associated with cognitive impulsivity on a delay discounting task.

Background: Head injuries are a major health care concern that can produce many long lasting cognitive, mental, and physical problems. An emerging literature indicates increased impulsivity in patients with a history of traumatic brain injury (TBI). In a recent study, Veterans with clinically-assessed history of mild TBI had increased cognitive, but not motor, impulsivity.

Predictors of Atrial Fibrillation Freedom Post Ablation with the Pentaspline Pulsed Field Ablation Catheter: Sub-Analysis of the ADVENT Study.

Background: Pulsed field ablation (PFA) has proven to be at least non-inferior to thermal ablation for paroxysmal atrial fibrillation (PAF). Predictors of AF freedom for PFA have not yet been described.

Objective: Identify clinical and procedural predictors of treatment success in PAF patients treated with the pentaspline PFA catheter.

Kabuki patients with CHDs: outcomes after cardiac surgery.

Objective: This study aims to examine the surgical outcome of Kabuki syndrome patients after neonatal congenital heart surgery.

Methods: This was a single-centre retrospective study of Kabuki syndrome patients undergoing neonatal congenital heart surgery from 2018 to 2023. Primary outcome was survival to discharge after index surgery.
