Duplex ultrasound assessment after venous vascular closure of 16–17 F OD femoral venotomy: AMBULATE EXPAND ultrasound substudy

The rapid evolution and expansion of complex electrophysiology and structural heart interventions have necessitated routine use of large-bore (16–24 F) femoral venous access. As these procedures are increasingly performed with a goal of same-day discharge, early hemostasis and rapid return to ambulation have become critical operational metrics. Within this modern care paradigm, tools that minimize postprocedural management, improve predictability from admission through discharge, and facilitate early ambulation while preserving patient comfort are critical.
