Insights
The FemoSeal vascular closure device (VCD) significantly reduces vascular complications and hematomas after cardiac catheterization compared to manual compression. It also shortens the time to hemostasis, improving patient outcomes.
Area of Science:
- Cardiology
- Vascular Surgery
- Medical Devices
Background:
- Limited evidence exists comparing contemporary vascular closure devices (VCDs) to manual compression.
- Assessing FemoSeal VCD performance in transfemoral diagnostic angiography is crucial.
Purpose of the Study:
- To evaluate the safety and efficacy of the FemoSeal VCD versus manual compression for arteriotomy closure.
- To compare access-site vascular complications and time to hemostasis.
Main Methods:
- Subanalysis of 3018 patients from the ISAR-CLOSURE trial undergoing transfemoral diagnostic coronary angiography.
- Randomized assignment to FemoSeal VCD or manual compression.
- Primary endpoint: composite of access-site vascular complications at 30 days; Secondary endpoints: time to hemostasis, repeat manual compression.
Main Results:
- FemoSeal VCD group showed lower vascular access-site complications (6.0% vs 7.9%, P=.04), primarily due to fewer hematomas (4.3% vs 6.8%, P<.01).
- Time to hemostasis was significantly shorter with FemoSeal VCD (0.5 min vs 10 min, P<.001).
- Pseudoaneurysm rates were similar (1.5% vs 1.5%, P=.88), but repeat manual compression was higher with FemoSeal VCD (1.5% vs 0.7%, P=.03).
Conclusions:
- FemoSeal VCD use in transfemoral diagnostic coronary angiography reduces vascular access-site complications, particularly hematomas, compared to manual compression.
- FemoSeal VCD significantly shortens time to hemostasis.
- The device offers a safe and effective alternative to manual compression for arteriotomy closure.
Objectives:
To assess the safety and efficacy of arteriotomy closure with the intravascular FemoSeal vascular closure device (VCD; St. Jude Medical) compared to manual compression in patients undergoing diagnostic cardiac catheterization via the common femoral artery.
Background:
There is limited evidence on the performance of individual contemporary VCDs compared to manual compression.
Methods:
This is a subanalysis of 3018 patients who underwent transfemoral diagnostic coronary angiography and were randomly assigned to arteriotomy closure with either the intravascular FemoSeal VCD or manual compression within the investigator-initiated, large-scale, randomized, multicenter, open-label ISAR-CLOSURE trial. Primary endpoint was the composite of access-site related vascular complications at 30 days. Secondary endpoints were time to hemostasis and repeat manual compression.
Results:
Vascular access-site complications were lower in patients assigned to the FemoSeal VCD compared to manual compression (6.0% vs 7.9%; P=.04), driven by a lower incidence of hematomas in the FemoSeal group (4.3% vs 6.8%; P<.01). Pseudoaneurysm rates were comparable in both groups (1.5% vs 1.5%; P=.88). Time to hemostasis was significantly shortened with the FemoSeal VCD compared to manual compression (0.5 min [IQR, 0.2-1.0 min] vs 10 min [IQR, 10-15 min]; P<.001). However, repeat manual compression was increased with the FemoSeal VCD (1.5% vs 0.7%; P=.03).
Conclusion:
In patients undergoing transfemoral diagnostic coronary angiography, the use of the FemoSeal VCD is associated with shortened time to hemostasis and a reduction in vascular access-site complications driven by fewer hematomas when compared to manual compression.
