Study type
Description of intervention(s) / exposure
Arista AH is a topical absorbable haemostatic powder. Adult patients undergoing planned Cardiac Implantable Electronic Device (CIED) implantation or generator replacement will be considered for the study. If eligible they will be randomised in a 1:1 ratio to Conventional Arm or Intervention Arm.

In the intervention Arm participants will receive standard of care treatment in addition to Arista AH 1-3g powder applied to the CIED pocket by the operator, prior to skin closure. The amount of powder used will be at the operator's discretion, ensuring to adequately cover the following areas with Arista:
- Any visible micro-bleeders or areas of blood ooze
- Around venous access site
- Directly onto any visible muscular layers if the fascia is compromised
- Underneath the inner layer of skin where the CIED device will be placed

The procedure operator will be the Principal Investigator or a delegate trained to perform the study specific procedure. The participant will be unaware of randomisation arm allocation. Participants will be assessed pre-procedure (baseline), and post-procedure; pre-discharge, 1 month and 6 month. This will be in line with routine standard of care follow-up appointments.
ARISTA is used in accordance with label directions and is being used as an adjunctive hemostat to control bleeding/oozing from the pocket.
Intervention code [1] 321180 0
Treatment: Devices
Comparator / control treatment
Standard of Care includes. compression, electro-cautery, and/or ligature and
guideline-directed management of oral anticoagulation (OAC) peri-operatively (as per The 2018 European Heart Rhythm Association Practical Guide on the use of non-vitamin K antagonist oral anticoagulants in patients with atrial fibrillation).
Control group

Primary outcome [1] 328287 0
The incidence of pocket haematoma of grade 2 or greater. This is collected using clinical assessment using face-to-face follow-up.

Grade 2 haematomas extend beyond 2 cm of the device margin and/or cause considerable strain on the wound.

Grade 3 haematomas are those that require prolongation of hospitalization (defined as extended hospitalization or re-hospitalization for >24 hours, post index surgery, primarily due to hematoma) and/or requiring interruption of OAC (defined as reversal or intentional withholding, in response to pocket hematoma, resulting in sub-therapeutic anticoagulation for >24 hours).
Timepoint [1] 328287 0
Acute (pre-discharge) or subacute (within 6 weeks up to first device follow-up visit - primary endpoint.
Secondary outcome [1] 398365 0
Satisfactory haemostasis at conclusion of procedure according to clinician's response in a study-specific survey

Assessed at 3 timepoints:
- Predischarge
- First follow-up visit (within 6 weeks)

Secondary outcome [3] 398367 0
The incidence of wound infection up to 6 months post procedure. This is collected using clinical assessment using face-to-face follow-up, or ascertained through telephone follow-up.

At any point up to 6 months
Secondary outcome [4] 398368 0
Safety endpoint of post-operative fever. Body temperature will be assessed clinically using a clinical-grade thermometer.
Timepoint [4] 398368 0
Predischarge (within 24 hours post implant)
Secondary outcome [5] 398369 0
Incidence of adverse events, defined as any untoward medical occurrence, unintended disease or injury, or untoward clinical signs in participants, users or other persons,. Examples include, but are not limited to, myocardial infarction, haemothorax, cardiac tamponade, and thromboembolic events (e.g. stroke, deep venous thrombosis, pulmonary embolism).
Assessed using medical records assessment and telephone follow-up.
Timepoint [5] 398369 0

Secondary outcome [6] 398370 0
Health-related quality of life (HRQoL) measures relating to patient comfort and satisfaction (assessed using the EQ-5D-5L tool).
Timepoint [6] 398370 0
Assessed at 3 timepoints:
- Predischarge
- First follow-up visit (within 6 weeks)

Secondary outcome [7] 399246 0

Brief summary
Cardiac Implantable Electronic Device (CIED) therapy is a safe and effective therapy, but is not without complications. Bleeding complications, which can potentially be preventable, are of concern as they significantly increase the risk of infection with subsequently increased morbidity and mortality. Arista™AH Absorbable Hemostat (Arista) is a novel powder, that has been shown in surgical settings to be safe, effective and result in significantly reduced haemostasis time and requirement for blood transfusion. The aim of this study is to investigate the potential benefits of routine use of Arista in CIED implantation procedures. Participants will receive either standard of care, or standard of care in addition to the administration of Arista to the CIED pocket prior to skin
closure. It is expected that participants who receive Arista will have a lower incidence of device haematomas post-implant. Participants will be followed up for 6 months post device implant.
