Further study details as provided by Deutsches Herzzentrum Muenchen:

Primary Outcome Measures:
  • Composite of arterial access related complications [ Time Frame: 30 days ]

    Composite of arterial access related complications, defined as the composite of:

    • Rate of ipsilateral groin hematomas with largest diameter exceeding 5 cm
    • Pseudoaneurysm
    • AV-Fistula
    • Major bleeding
    • Critical limb ischemia
    • Local infection
    • Surgical repair
    • Revascularisation

Secondary Outcome Measures:
  • Time to hemostasis, from sheath removal to complete hemostasis [ Time Frame: 30 days ]
  • Device deployment failure [ Time Frame: 30 days ]
  • Need for repeated manual compression after end of closure procedure [ Time Frame: 30 days ]
  • Cost-benefit Analysis [ Time Frame: 30 days ]

Detailed Description:

Vascular closure devices have been shown to be safe and effective in reducing the time to hemostasis and immobilization when compared to manual compression following coronary angiography. This effect is beneficial in patients presenting with chronic back pain, prostate enlargement, mental impairment or other disorders that preclude prolonged bed rest.

However, adequately powered large scale randomized trials with vascular closure devices remain a gap in the scientific literature.

This trial compares, in a randomised design two novel vascular closure devices (FemoSeal & ExoSeal) versus manual compression after coronary angiography. This study is aimed to investigate if novel vascular closure devices are noninferior to manual compression regarding access site complications.
