This case of PJRT shows negative linking on ventriculoatrial intervals after atrial differential pacing. Interpreting the results of atrial differential pacing may be challenging in cases where the pacing site affects retrograde conduction or when retrograde conduction is unstable.

Severe tricuspid regurgitation (TR) can lead to significant enlargement of the right atrium (RA) and poses unique clinical challenges. We report this case of a 17-year-old boy previously misdiagnosed with Ebstein anomaly who presented with dyspnea and palpitations. Initial examination revealed irregular heart rhythm, distended neck veins, and a significant murmur.

Introduction: Arterial dissection is an important etiology of stroke in young adults and may demonstrate distinct thrombus characteristics. While most studies have focused on compositional differences between cardioembolic (CE) and non-cardioembolic thrombi, systematic analyses of dissection-related thrombi remain scarce. This study characterized the compositions of dissection thrombi, compared them with those of non-dissection thrombi, and explored compositional variations among stroke etiologies.
