Comparison of Vascular Closure Devices Versus Manual Compression After Femoral Artery Puncture in Women.

BACKGROUND: The value of vascular closure devices (VCD) in women undergoing transfemoral catheterization has not been sufficiently investigated. METHODS AND RESULTS: This is a sex-specific analysis of 1395 women enrolled in a large-scale, randomized, multicenter trial, in which patients undergoing transfemoral diagnostic coronary angiography were randomly assigned in a 1:1:1 ratio to arteriotomy closure with an intravascular VCD, extravascular VCD, or manual compression (MC). Primary objective was to assess the safety and efficacy of 2 different VCD compared with MC regarding vascular access-site complications at 30 days. A secondary comparison was between 2 different types of contemporary VCD. Overall, women were at higher risk for vascular access-site complications compared with men (9.0% versus 6.4%; P=0.002). Vascular access-site complications were comparable in women assigned to VCD and MC (8.6% versus 9.8%; P=0.451). There was no interaction of treatment effect and sex ( Pinteraction=0.970). Time to hemostasis was significantly shortened with VCD compared with MC (1 [interquartile range, 0.5-2.0] minutes) versus 11 [interquartile range, 10-15] minutes; P<0.001); however, more women with VCD required repeat MC (2.4% versus 0.6%; P=0.018). The use of the intravascular compared with the extravascular VCD was associated with a numerical reduction in vascular access-site complications (6.6% versus 10.7%; P=0.027) and significant reductions in time to hemostasis and VCD failure. CONCLUSIONS: In women undergoing diagnostic coronary angiography via the common femoral artery, VCD and MC provided comparable safety, while time to hemostasis was reduced with VCD.

Comparison of the FemoSeal Vascular Closure Device With Manual Compression After Femoral Artery Puncture - Post-hoc Analysis of a Large-Scale, Randomized Clinical Trial.

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.
