Randomized Comparison of MynxGrip Vascular Closure Device and Manual Compression for Closure After Femoral Access Angiography. The Closure Devices Used in Every Day Practice Study, CLOSE-UP III Trial

Not Applicable

Completed

• Conditions: Coronary Disease

• Registration Number: NCT02237430
• Lead Sponsor: Aarhus University Hospital Skejby

Brief Summary

Is the MynxGrip (test device) non-inferior to manuel compression (standard comparator) in the incidence of adverse access site related events in-hospital, at 30 days and at 6 months.

Detailed Description

Prospective, randomized (1:1), controlled, non-blinded, single center study in 2000 patients comparing the MynxGrip (test device) and manuel compression (standard comparator). Safety and efficacy endpoints will be reported for in-hospital, 30 days and 6 months.

Primary Outcome Measures

Name	Time	Method
Incidence at 30 days of the composite endpoint of serious access site related major adverse vascular events (MAVE)	30 days	This includes: Major bleeding and/or blood transfusion, pseudoaneurysm with indication for treatment, arteriovenous fistula, groin surgery of leg, definitely or possible can be related to the closure procedure, infection needing antibiotics.

Secondary Outcome Measures

Name	Time	Method
Need for medical evaluation of possible closure procedure related symptom(s)	30 days
Pain and discomfort related to the closure procedure	Closure procedure and 30 days	Assessed on a numerical rating scale (NRS) from 0 (no pain or discomfort) to 10 (worst possible pain or discomfort).
Time to mobilization	participants will be followed for the duration of hospital stay, an expected average of 2 days	From start of closure procedure to patient is mobilised.
Bleedings according to the Bleeding Academic Research Consortium (BARC) definitions	1 hour and 30 days
Major bleeding and/or bleeding necessitation blood transfusion	30 days and 6 months
Pseudoaneurysm with indication for treatment	30 days and 6 months
Arteriovenous fistula	30 days and 6 months
Vasovagal reaction until 5 minutes after end of closure procedure	30 minutes
Time (min) to haemostasis	30 days	From inserting the device (MynxGrip) until haemostasis and from beginning of manual compression to immediately haemostasis
In-hospital large groin haematoma	Participants will be followed for the duration of hospital stay, an expected average of 2 days	Larger than 5 x 5 cm measured by ruler in the catheterisation laboratory or at discharge
Groin surgery and/or possible related vascular surgery	30 days and 6 months
Device failure	30 minutes
Need for new onset of manual compression	30 days
Infection needing antibiotics	30 days and 6 months
