Klippel-Trenaunay syndrome with multiorgan vascular involvement and gastrointestinal bleeding: A case report and literature review.

Rationale: To explore the early diagnosis and treatment of Klippel-Trenaunay syndrome (KTS), and provide useful and systematic clinical references for the diagnosis and treatment of such congenital vascular malformations combined with long-term gastrointestinal bleeding.

Patient Concerns: A 32-year-old male patient was admitted due to "intermittent rectal bleeding for 32 years, worsening for over 3 months." The patient had experienced intermittent bright red rectal bleeding since birth.

The influence of epicardial adipose tissue on the prognosis of atrial fibrillation patients undergoing radiofrequency ablation combined with left atrial appendage occlusion.

Atrial fibrillation is the most common arrhythmia in adults. The interplay between epicardial adipose tissue and atrial fibrillation has garnered significant scientific interest. Recently, the combined approach of radiofrequency ablation and left atrial appendage occlusion has become a widely adopted strategy for managing non-valvular atrial fibrillation patients at high risk of thrombus formation.
