Plain English Summary

Background and study aims
Coronary angiograms are performed to examine the condition of the arteries that supply blood to the heart muscle. Coronary angioplasty involves the widening of the heart arteries with a balloon, often followed by the placement of a metal mesh-like structure called a stent. Traditionally these have been performed by passing a narrow tube called a catheter through a sheath inserted into an artery in the groin called the femoral artery. There has been a rapidly growing trend to perform these procedures through an artery in the wrist called the radial artery. The radial route has the advantage of lower complications and patients are often able to move earlier following their procedures. The radial artery however is smaller than the femoral, it is also more muscular and prone to spasm. To help prevent this, radial sheaths can be coated with a slippery substance. In the past a small number of patients have reported a skin reaction at the puncture site (thought to be from this coating), a couple of weeks or so after their procedure. The manufacturers of the sheath have made changes to their product. The aim of this is to eliminate or reduce the chance of this reaction occurring. Subsequently the study team would now like to follow the patients after their procedure to confirm that their skin puncture heals satisfactorily. We will also collect other routine information about the performance of the sheath such as whether the procedure could be completed as planned.

Who can participate?
All patients, aged over 18 years, admitted to the study hospital for a planned radial coronary procedure can participate in the study.

What does the study involve?
Participating patients will undergo their procedure as normal. Before they go home, a member of the study team will provide them with some additional and contact information. If they experience any problems with their puncture site, they will be encouraged to contact the study team. If they do not experience a problem they will be contacted at around 28 days to confirm the absence of problems.

What are the possible risks and benefits of participating?
There are no direct benefits to any individuals taking part. Personal results will not be used in any way without their permission. The overall anonymous group results of the study may be directly used to inform the manufacturer of the optimal design of their product. There are no additional risks in taking part in the study. The risks are the same as those explained by the doctor when they were asked to consent for the procedure.

Where is the study run from?
This study is running from Liverpool Heart and Chest Hospital NHS Foundation Trust, UK.

When is the study starting and how long is it expected to run for?
It is anticipated that recruitment will start in early October 2013 and will continue till end of March 2014.

Who is funding the study?
This study is funded by Cook Medical (USA).

Condition

Cutaneous granuloma formation following the use of radial introducer sheaths used in coronary angiography and angioplasty procedures

Intervention

Patients will be provided with some additional information prior to discharge. What they might expect with normal healing will be explained to them. Patients will be encouraged to contact the study team via email or dedicated phone line with voice messaging facilities. Such patients will be invited to return to the study centre for clinical review to allow formal assessment of the puncture site for the primary outcome measure. All other patients will be contacted by telephone, text or email at 28 days (+ 7 days) to confirm the absence of problems. Patients will equivocal responses will be invited for clinical assessment.

It is important to note that the sheath being studied is currently in use in all patients undergoing coronary angiography or angioplasty via the radial artery at the study centre. In participating in the study, patients are not being asked to trial a new or different sheath from any other patient.

Drug names

Primary outcome measures

The incidence of granuloma formation by 28 days defined as an indurated, erythematous lesion, at least 3mm in its longest diameter, not related to haematoma

Secondary outcome measures

1. The rate of successful insertion of the study sheath device
2. The rate of successful completion of the coronary procedure through the initial sheath device
3. The incidence of administration of intra-arterial vasodilator agents for the management of coronary artery spasm (routine administration is not practice at the study centre)

The rate of other vascular complications
1. Small haematoma ≤ 3cm diameter
2. Large haematoma > 3cm diameter
3. The incidence of blood transfusion related to access site complications
4. The incidence of surgical or other interventional procedures for the management of vascular access complications
5. Delayed discharge necessitating an unplanned night or more in hospital related to vascular access complications

All secondary outcome measures are recorded following the index procedure and prior to hospital discharge.
