Infected Urachal Cyst Mimicking Urachal Carcinoma: A Rare Cause of Lower Abdominal Tenderness.

Teaching Point: Infected urachal cysts are a rare cause of abdominal complaints and can be accurately diagnosed by abdominal ultrasound and computed tomography (CT).

Repositioning and extraction of stylet-driven pacing leads with extendable helix used for left bundle branch area pacing.

Conventional stylet-driven leads with extendable helix can be implanted successfully for left bundle branch area pacing (LBBAP) with a low acute complication rate. We report two cases in which lead repositioning after a first unsuccessful attempt to LBBAP was associated with fracture of the helix rotating mechanism and failure to fully extract the pacing lead.
