Suture-mediated closure of the femoral access site after cardiac catheterization: results of the suture to ambulate aNd discharge (STAND I and STAND II) trials

ESR Essentials: arterial vascular access and closure devices-practice recommendations by the Cardiovascular and Interventional Radiological Society of Europe

Vascular access is the initial, very important, step of endovascular procedures. Various access sites include the common femoral artery, brachial artery, radial artery, popliteal artery, and distal tibial vessels (pedal arteries). Successful arterial access requires advanced knowledge of anatomy, as well as proper training and experience. Today, vascular access should be obtained using real-time, ultrasound guidance to reduce access time, patient discomfort, and puncture-related complications including dissection, arteriovenous communication, and bleeding. Nevertheless, high-level evidence to support this recommendation in peripheral procedures is limited and level A data are mainly derived from randomized cardiac trials investigating only radial and femoral access. Vascular closure devices (VCDs) for femoral access can be broadly categorized as active closure devices, compression assist devices, and external/topical hemostasis devices. There is high-level evidence demonstrating that their use is related to less time for ambulation and increased patient satisfaction. However, available data failed to clearly demonstrate a benefit in complications compared to standard manual compression in peripheral endovascular arterial procedures, and thrombotic and infectious complications reported following VCD use remain an issue. Heterogeneity noted in the literature, caused by the vast variety of devices, access sites, sheath sizes, clinical scenarios, and procedures, poses difficulties in data analysis and future study design. As a result, an individualized VCD use is currently suggested for ≥ 5 Fr femoral artery access not only to reduce time to hemostasis and ambulation and to improve patient comfort, but also to reduce bleeding complications in cases of femoral access with increased bleeding risk, deranged coagulation, and large-bore access, though a high level of evidence to support this later recommendation is limited. KEY POINTS: US guidance is strongly recommended for femoral access and is mandatory to obtain more challenging access. The use of VCDs for femoral hemostasis is generally safe, effective, and currently supported by level I evidence. Proper training and correct VCD choice, based on the patient's individual characteristics, are imperative to optimize outcomes.

Real-time ultrasound-guided hemostasis using suture-mediated closure device

PURPOSE

Suture-mediated hemostasis device takes a long time to train and have limitations in finding appropriate compression point depending on the tactile sense of the hands. If the appropriate compression point is determined using ultrasound and the instrument is used under ultrasound guidance, it is expected to reduce the technical failure and additional manual compression.

MATERIALS AND METHODS

This retrospective study included 104 patients in whom the ProGlide vascular closure device (Abbott Vascular, Redwood City, CA, USA) was deployed to close common femoral artery access between January 2022 and June 2022. Ultrasound-guided hemostasis was performed in 54 patients and 50 conventional hemostasis was performed. We analyzed the medical records (procedure, patient body mass index, coagulation function, visual imaging, ultrasound imaging, time to achieve hemostasis) and post-treatment medical records (progress records, nursing records) to investigate the technical success rate and complications (hematoma, pseudoaneurysm formation, SFA occlusion, access site infection) of the procedure.

RESULTS

Technical success rate was 52/54 (Ultrasound guided group) and 47/50 (conventional group), respectively (p > 0.05). Mean hemostasis time was 271 s (US guided group) and 317 s (conventional group), respectively (p > 0.05). Additional manual compression was applied in 7/54 (US guided group) and 15/50 (conventional group) (p < 0.05). In both groups, complications such as hematoma formation, access site infection and SFA occlusion did not occur.

CONCLUSION

Using ultrasound guidance when using the suture mediated closing device reduces the frequency of additional manual compression without increased risk of complication.

Efficacy and Safety of Axiostat® Hemostatic Dressing in Aiding Manual Compression Closure of the Femoral Arterial Access Site in Patients Undergoing Endovascular Treatments: A Preliminary Clinical Experience in Two Centers

BACKGROUND

Hemostasis of the femoral arterial access site by manual compression or a vascular closure device is critical to the safe completion of any endovascular procedure. Previous investigations evaluated the hemostatic efficacy at the radial access site of some chitosan-based hemostatic pads. This study aims to assess the efficacy and safety of a new chitosan-based hemostatic dressing, namely Axiostat®, in aiding manual compression closure of the femoral arterial access site in patients undergoing endovascular treatments. Furthermore, the outcomes were compared with evidence on manual compression alone and vascular closure devices.

METHODS

This investigation is a two-center retrospective analysis of 120 consecutive patients who had undergone, from July 2022 to February 2023, manual compression closure of the femoral arterial access site aided by the Axiostat® hemostatic dressing. Endovascular procedures performed with introducer sheaths ranging from 4 Fr to 8 Fr were evaluated.

RESULTS

Primary technical success was achieved in 110 (91.7%) patients, with adequate hemostasis obtained in all cases of prolonged manual compression requirements. The mean time-to-hemostasis and time-to-ambulation were 8.9 (±3.9) and 462 (±199) minutes, respectively. Clinical success was achieved in 113 (94.2%) patients, with bleeding-related complications noted in 7 (5.8%) patients.

CONCLUSIONS

Manual compression aided by the Axiostat® hemostatic dressing is effective and safe in achieving hemostasis of the femoral arterial access site in patients undergoing endovascular treatment with a 4-8 Fr introducer sheath.

Preclosure of large bore venous access sites in patients undergoing transcatheter mitral replacement and repair

OBJECTIVE

We aim to report on the efficacy and safety of large bore venous access (LBVA) preclosure with Perclose™ (Abbott Vascular Devices) suture-mediated device use following transcatheter edge-to-edge (TEER) and replacement (TMVR).

BACKGROUND

Patients requiring TEER and TMVR require LBVA. Clinical outcome data on the use of suture-mediated devices for LBVA site closure are limited.

METHODS

Between 2012 and 2019, 354 consecutive high-risk patients with mitral valvular heart disease underwent TEER (n = 287) with MitraClip and TMVR (n = 67) with Edwards Sapien Valves. Patients had LBVA with 24 or 16 French sheaths. All patients underwent preclosure of LBVA except for one that underwent manual hemostasis.

RESULTS

There were no closure device failures. None of the cases required surgical repair of the access site following venous preclosure. Two cases had large hematomas (>6 cm) following Perclose in each group. Six cases had small hematomas (<6 cm and >2 cm) with three in each group. There was one major bleeding using Mitral Valve Academic Research Consortium 2 definition (retroperitoneal bleed from arterial puncture) unrelated to the venous closure. Transfusion related to vascular access complication was required in five cases. There were two immediate acute deep venous thromboses postprocedure; one of which occurred after preclosure. There were no arteriovenous malformations, pseudoaneurysms, or access site infections reported following Perclose.

CONCLUSION

In this large sample size analysis, Proglide preclosure technique is a feasible and safe alternative approach to achieving hemostasis after removal of LBVA sheaths in patients undergoing TEER and TMVR. Randomized trials are needed to compare the different modalities of hemostasis.

Vascular Closure: the ABC's

PURPOSE OF REVIEW

Vascular access and closure is a key part of endovascular procedures, and access site-related complications are an independent predictor of adverse procedural outcomes. The purpose of this review is to discuss the methods of vascular closure including manual compression, vascular closure devices (VCDs) for both arterial and venous arteriotomies, their mechanisms, and access site-related complications.

RECENT FINDINGS

Various VCDs have been approved over the last three decades. These devices have different mechanisms to achieve hemostasis and are generally categorized into active and passive approximators. Studies have largely found that they are non-inferior to manual compression. Uncomplicated vascular closure is pertinent to avoid adverse procedure-related outcomes. The emergence of VCDs has reduced time to hemostasis, facilitating early ambulation and discharge and reducing hospitalization cost with comparable complication rate to manual compression. Nonetheless, they should be used in favorable vascular anatomy and are not intended to reduce complications.

Real-world experience of suture-based closure devices: Insights from the FDA Manufacturer and User Facility Device Experience

OBJECTIVES

We analyzed post-marketing surveillance data from the United States Food and Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database for suture-based vascular closure devices (VCDs) - Perclose ProGlide (Abbott, Chicago, Illinois) and Prostar XL (Abbott).

BACKGROUND

Suture-based VCDs are mostly used for large-bore femoral arterial access-site closure. Real-world, contemporary experience on the most commonly reported complications and modes of failure associated with these devices is limited.

METHODS

Post-marketing surveillance data from the FDA MAUDE database, for the ProGlide system and for the Prostar XL system, were analyzed, yielding 827 Perclose ProGlide reports and 175 Prostar XL reports.

RESULTS

Of the 827 reports of major complications involving the Perclose ProGlide devices, 404 reports involved injury, and one involved death related to the device. In the Prostar XL analysis, 94 reports involved injury, and one involved death. Bleeding from vessel injury was the most common adverse outcome described with both devices, followed by hematoma and thrombus. Surgical repair was the most commonly used treatment strategy. In terms of device malfunction, suture-related malfunction (212 reports) was most commonly seen in the Perclose ProGlide group, while failed deployment was most commonly seen in the Prostar XL group.

CONCLUSIONS

Our analysis of the MAUDE database demonstrates that in real-world practice, suture-based VCDs were found to be associated with complications, including vascular injury, difficulties with the device itself, and even death. Ongoing user education and pre-procedural patient selection are important to minimize risks associated with suture-based vascular closure devices.

Large-bore arterial access in the era of structural cardiovascular disease

Over the last two decades, the medical community witnessed an outstanding and accelerated development on minimally invasive therapies. The definition of what constitutes large bore access is subject to discussion, however within the field it is generally accepted to reflect a catheter diameter exceeding 8-French. We sought in this review to explore the evolution, characteristics and vascular compatibility of the current commercially available devices, analyze the devices along with access site-specific complications rates and finally review the present methods for percutaneous vascular closure.

Clinical and economic outcomes of ProGlide compared with surgical repair of large bore arterial access

Aim: This study compared real-world complication rates, hospitalization duration and costs, among patients undergoing arterial repair using the Perclose ProGlide (ProGlide) versus surgical cutdown (Cutdown). Materials & methods: Retrospective study of matched patients who underwent transcatheter aortic valve replacement/repair, endovascular abdominal aortic aneurysm repair, thoracic endovascular aortic repair or balloon aortic valvuloplasty with arterial repair by either ProGlide or Cutdown between 1 January 2013 and 24 April 2017. Results: Infections and blood transfusions were lower in the ProGlide cohort. Patients in the ProGlide cohort had a 42.5% shorter index hospitalization, which corresponded to US$14,687 lower costs. Conclusion: The use of ProGlide for arterial repair was associated with significantly lower transfusion rates, shorter index hospitalization and lower hospitalization costs compared with surgical cutdown.

Safety and Efficacy of Femoral Artery Closure with the FemoSeal Device After Cerebral Thrombectomy Using an 8 French Sheath

PURPOSE

To evaluate the feasibility and safety of using the FemoSeal vascular closure device (VCD) to seal 8F access sites during mechanical thrombectomy for stroke.

METHODS

A retrospective review of a prospective database was undertaken to evaluate the safety and efficacy of femoral arterial closure using FemoSeal device in all patients who underwent mechanical thrombectomy using an 8F sheath between January 2015 and July 2017. Efficacy endpoints were the successful deployment of the system and haemostasis success. Safety endpoints included the incidence of in hospital access site haematoma >5 cm, bleeding complications, pseudoaneurysms, arteriovenous fistula, infection, or other complications requiring surgery.

RESULTS

197 patients (96 men; mean age 68 years, range 25-99) were included. Successful haemostasis with FemoSeal was obtained in 98.9% of the patients. Only one haematoma >5 cm (0.5%) was observed, which reabsorbed spontaneously without issue. Nine haematomas <5 cm (4.5%) were also found. No major complications requiring surgical repair or transfusion were observed. There were no pseudoaneurysms, arteriovenous fistulae, or infections.

CONCLUSION

The use of the FemoSeal device to close an 8F access sheath puncture site is feasible and safe, with a low complication rate.

Relationship Between Femoral Vascular Closure Devices and Short-Term Mortality From 271 845 Percutaneous Coronary Intervention Procedures Performed in the United Kingdom Between 2006 and 2011: A Propensity Score-Corrected Analysis From the British Cardiovascular Intervention Society

BACKGROUND

The impact of vascular closure devices (VCDs) via the femoral arterial access site on short-term mortality in patients undergoing percutaneous coronary intervention is currently unknown.

METHODS AND RESULTS

The association between femoral arterial vascular access site management (manual pressure [including external clamp] versus VCD) and 30-day mortality was examined in a national real-world registry of 271 845 patients undergoing percutaneous coronary intervention for elective, non-ST-segment-elevation myocardial infarction and ST-segment-elevation myocardial infarction indications in the United Kingdom between 2006 and 2011. Crude and propensity score-corrected analyses were performed using Cox regression, with additional analyses undertaken in clinically relevant subgroups; 40.1% (n=109 001) of subjects were treated with manual pressure and 59.9% (n=162 844) with VCD. Subjects treated with VCD had fewer comorbidities and were less likely to present with ST-segment-elevation myocardial infarction and cardiogenic shock (P<0.001). Crude 30-day mortality was lower in the group treated with VCD compared with manual pressure (hazard ratio [HR], 0.58; 95% confidence interval [CI], 0.54-0.61; 1.4% versus 2.4%, log rank P<0.0001), findings that were substantially reduced but persisted after propensity score correction (HR, 0.91; 95% CI, 0.86-0.97; 1.8% versus 2.0% versus P<0.001). A more pronounced association of VCD with a reduction in 30-day mortality was evident in females (HR, 0.85; 95% CI, 0.77-0.94; Pinteraction=0.037), presentation with acute coronary syndrome (HR, 0.88; 95% CI, 0.83-0.94; Pinteraction=0.0027), or recent lysis (HR, 0.63; 95% CI, 0.40-1.01; Pinteraction=0.0001).

CONCLUSIONS

When compared with manual pressure, VCD was associated with a minor short-term (30-day) prognostic benefit after propensity score correction in the global population and clinically relevant subgroups. The potential for residual confounding factors impacting on short-term mortality cannot be excluded, despite the study having measured and balanced all recorded confounder factors.

Usefulness of a Nonsuture Closure Device in Patients Undergoing Diagnostic Coronary and Peripheral Angiography

Vascular access site complications can follow diagnostic coronary and peripheral angiography. We compared the complication rates of the Catalyst vascular closure device, with the complication rates after manual compression in patients undergoing diagnostic angiographic procedures via femoral access. We studied 1,470 predominantly male patients undergoing diagnostic coronary and peripheral angiography. Catalyst closure devices were used in 436 (29.7%) patients and manual compression was used in 1,034 (70.3%) patients. The former were allowed to ambulate after 2 hours, while the latter were allowed to ambulate after 6 hours. Major complications occurred in 4 (0.9%) patients who had a Catalyst device and in 14 (1.4%) patients who had manual compression (odds ratio [OR]: 0.67, 95% confidence interval [CI]: 0.22-2.1, p  = 0.49). Any complications occurred in 51 (11.7%) patients who had a Catalyst closure device and in 64 (6.2%) patients who had manual compression (OR: 2, CI: 1.4-3, p  < 0.01). After adjustment for other variables and for a propensity score reflecting the probability to receive the closure device, the association of major complications with the use of the closure device remained not significant (OR: 0.54, 95% CI: 0.17-1.7, p  = 0.29), while the association of any complications with the use of the Catalyst device remained significant (OR: 1.9, 95% CI: 1.3-2.9, p  < 0.01). The Catalyst device was not associated with an increased risk of major groin complications but was associated with an increased risk of any complications compared with manual compression. Patients receiving the closure device ambulated sooner.

Treatment of Angio-Seal® Vascular Closure Device-Induced Acute Femoral Artery Occlusion with SilverHawk® Directional Atherectomy

Vascular closure devices provide a safe and cost-effective method to achieve rapid hemostasis and early ambulation after angiographic procedures. Rarely, they can result in arterial injury with resultant stenosis or acute arterial closure requiring open surgical intervention. We report an Angio-Seal® vascular closure device-induced acute arterial closure successfully treated percutaneously with the SilverHawk® plaque excision system. This report discusses the possible mechanisms of Angio-Seal® induced arterial occlusion and various percutaneous options for treatment.

Femoral arterial closure using ProGlide® is more efficacious and cost-effective when ambulating early following cardiac catheterization

OBJECTIVE

This was a prospective, single-center study evaluating the efficacy and cost-effectiveness of early ambulation (within 30 min) following femoral artery closure with the ProGlide® suture-mediated vascular closure device (PD) in patients undergoing diagnostic cardiac catheterization compared with manual compression.

BACKGROUND

It is unclear whether early ambulation with ProGlide is safe or is associated with patient satisfaction and cost savings as compared with manual compression (MC).

METHODS AND RESULTS

Inclusion criteria were met in 170 patients (85 PD and 85 MC patients). Patients ambulated 20 ft. within 30 min (PD) or after the requisite 4 h recumbent time (MC) if feasible. Primary endpoint was time-to-ambulation (TTA) following device closure. We also directly compared the safety of closure, times-to-hemostasis (TTH), -ambulation (TTA) and -discharge (TTD) with MC and, using a fully allocated cost model, performed cost analysis for both strategies. Multivariate analysis was used to determine predictors of patient satisfaction. The primary endpoint of safe, early ambulation was achieved following closure (mean of 27.1 ± 14.9 min; 95% confidence interval [CI] 25.2-30.2). Predictors of patient satisfaction in the PD group were absence of pain during closure, decreased TTA, and drastic reductions in TTD; the latter contributed indirectly to significant cost savings in the PD group (1250.3 ± 146.4 vs. 2248.1 ± 910.2 dollars, respectively; P < 0.001) and incremental cost savings by strategy also favored closure over MC ($84,807).

CONCLUSIONS

ProGlide is safe and effective for femoral artery closure in patients who ambulate within 30 min after cardiac catheterization; translating into improved patient satisfaction and substantial cost savings.

Vascular closure devices for femoral arterial puncture site haemostasis

BACKGROUND

Vascular closure devices (VCDs) are widely used to achieve haemostasis after procedures requiring percutaneous common femoral artery (CFA) puncture. There is no consensus regarding the benefits of VCDs, including potential reduction in procedure time, length of hospital stay or time to patient ambulation. No robust evidence exists that VCDs reduce the incidence of puncture site complications compared with haemostasis achieved through extrinsic (manual or mechanical) compression.

OBJECTIVES

To determine the efficacy and safety of VCDs versus traditional methods of extrinsic compression in achieving haemostasis after retrograde and antegrade percutaneous arterial puncture of the CFA.

SEARCH METHODS

The Cochrane Vascular Trials Search Co-ordinator searched the Specialised Register (April 2015) and the Cochrane Central Register of Controlled Trials (CENTRAL) (2015, Issue 3). Clinical trials databases were searched for details of ongoing or unpublished studies. References of articles retrieved by electronic searches were searched for additional citations.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials in which people undergoing a diagnostic or interventional procedure via percutaneous CFA puncture were randomised to one type of VCD versus extrinsic compression or another type of VCD.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data and assessed the methodological quality of trials. We resolved disagreements by discussion with the third author. We performed meta-analyses when heterogeneity (I(2)) was < 90%. The primary efficacy outcomes were time to haemostasis and time to mobilisation (mean difference (MD) and 95% confidence interval (CI)). The primary safety outcome was a major adverse event (mortality and vascular injury requiring repair) (odds ratio (OR) and 95% CI). Secondary outcomes included adverse events.

MAIN RESULTS

We included 52 studies (19,192 participants) in the review. We found studies comparing VCDs with extrinsic compression (sheath size ≤ 9 Fr), different VCDs with each other after endovascular (EVAR) and percutaneous EVAR procedures and VCDs with surgical closure after open exposure of the artery (sheath size ≥ 10 Fr). For primary outcomes, we assigned the quality of evidence according to GRADE (Grades of Recommendation, Assessment, Development and Evaluation) criteria as low because of serious imprecision and for secondary outcomes as moderate for precision, consistency and directness.For time to haemostasis, studies comparing collagen-based VCDs and extrinsic compression were too heterogenous to be combined. However, both metal clip-based (MD -14.81 minutes, 95% CI -16.98 to -12.63 minutes; five studies; 1665 participants) and suture-based VCDs (MD -14.58 minutes, 95% CI -16.85 to -12.32 minutes; seven studies; 1664 participants) were associated with reduced time to haemostasis when compared with extrinsic compression.For time to mobilisation, studies comparing collagen-, metal clip- and suture-based devices with extrinsic compression were too heterogeneous to be combined. No deaths were reported in the studies comparing collagen-based, metal clip-based or suture-based VCDs with extrinsic compression. For vascular injury requiring repair, meta-analyses demonstrated that neither collagen (OR 2.81, 95% CI 0.47 to 16.79; six studies; 5731 participants) nor metal clip-based VCDs (OR 0.49, 95% CI 0.03 to 7.95; three studies; 783 participants) were more effective than extrinsic compression. No cases of vascular injury required repair in the study testing suture-based VCD with extrinsic compression.Investigators reported no differences in the incidence of infection between collagen-based (OR 2.14, 95% CI 0.88 to 5.22; nine studies; 7616 participants) or suture-based VCDs (OR 1.66, 95% CI 0.22 to 12.71; three studies; 750 participants) and extrinsic compression. No cases of infection were observed in studies testing suture-based VCD versus extrinsic compression. The incidence of groin haematoma was lower with collagen-based VCDs than with extrinsic compression (OR 0.46, 95% CI 0.40 to 0.54; 25 studies; 10,247 participants), but no difference was evident when metal clip-based (OR 0.79, 95% CI 0.46 to 1.34; four studies; 1523 participants) or suture-based VCDs (OR 0.65, 95% CI 0.41 to 1.02; six studies; 1350 participants) were compared with extrinsic compression. The incidence of pseudoaneurysm was lower with collagen-based devices than with extrinsic compression (OR 0.74, 95% CI 0.55 to 0.99; 21 studies; 9342 participants), but no difference was noted when metal clip-based (OR 0.76, 95% CI 0.20 to 2.89; six studies; 1966 participants) or suture-based VCDs (OR 0.79, 95% CI 0.25 to 2.53; six studies; 1527 participants) were compared with extrinsic compression. For other adverse events, researchers reported no differences between collagen-based, clip-based or suture-based VCDs and extrinsic compression.Limited data were obtained when VCDs were compared with each other. Results of one study showed that metal clip-based VCDs were associated with shorter time to haemostasis (MD -2.24 minutes, 95% CI -2.54 to -1.94 minutes; 469 participants) and shorter time to mobilisation (MD -0.30 hours, 95% CI -0.59 to -0.01 hours; 469 participants) than suture-based devices. Few studies measured (major) adverse events, and those that did found no cases or no differences between VCDs.Percutaneous EVAR procedures revealed no differences in time to haemostasis (MD -3.20 minutes, 95% CI -10.23 to 3.83 minutes; one study; 101 participants), time to mobilisation (MD 1.00 hours, 95% CI -2.20 to 4.20 hours; one study; 101 participants) or major adverse events between PerClose and ProGlide. When compared with sutures after open exposure, VCD was associated with shorter time to haemostasis (MD -11.58 minutes, 95% CI -18.85 to -4.31 minutes; one study; 151 participants) but no difference in time to mobilisation (MD -2.50 hours, 95% CI -7.21 to 2.21 hours; one study; 151 participants) or incidence of major adverse events.

AUTHORS' CONCLUSIONS

For time to haemostasis, studies comparing collagen-based VCDs and extrinsic compression were too heterogeneous to be combined. However, both metal clip-based and suture-based VCDs were associated with reduced time to haemostasis when compared with extrinsic compression. For time to mobilisation, studies comparing VCDs with extrinsic compression were too heterogeneous to be combined. No difference was demonstrated in the incidence of vascular injury or mortality when VCDs were compared with extrinsic compression. No difference was demonstrated in the efficacy or safety of VCDs with different mechanisms of action. Further work is necessary to evaluate the efficacy of devices currently in use and to compare these with one other and extrinsic compression with respect to clearly defined outcome measures.

Network Meta-analysis of Randomized Trials on the Safety of Vascular Closure Devices for Femoral Arterial Puncture Site Haemostasis

The safety of vascular closure devices (VCDs) is still debated. The emergence of more related randomized controlled trials (RCTs) and newer VCDs makes it necessary to further evaluate the safety of VCDs. Relevant RCTs were identified by searching PubMed, EMBASE, Google Scholar and the Cochrane Central Register of Controlled Trials electronic databases updated in December 2014. Traditional and network meta-analyses were conducted to evaluate the rate of combined adverse vascular events (CAVEs) and haematomas by calculating the risk ratios and 95% confidence intervals. Forty RCTs including 16868 patients were included. Traditional meta-analysis demonstrated that there was no significant difference in the rate of CAVEs between all the VCDs and manual compression (MC). Subgroup analysis showed that FemoSeal and VCDs reported after the year 2005 reduced CAVEs. Moreover, the use of VCDs reduced the risk of haematomas compared with MC. Network meta-analysis showed that AngioSeal, which might be the best VCD among all the included VCDs, was associated with reduced rates of both CAVE and haematomas compared with MC. In conclusion, the use of VCDs is associated with a decreased risk of haematomas, and FemoSeal and AngioSeal appears to be better than MC for reducing the rate of CAVEs.

Feasibility and clinical benefit of a suture-mediated closure device for femoral vein access after percutaneous edge-to-edge mitral valve repair

AIMS

We assessed feasibility, efficacy and safety of a suture-mediated closure device, Perclose Proglide (Abbott Vascular Devices, Santa Clara, CA, USA), for closure of the femoral vein access after percutaneous MitraClip (Abbott Vascular Devices) implantation.

METHODS AND RESULTS

Venous access of 80 consecutive patients undergoing percutaneous mitral valve repair using the MitraClip device was managed either by manual compression, "figure eight" suture and compression bandage for 12 hours, or by applying the Proglide device for haemostasis after the procedure (40 patients each group). Patients with Proglide closure showed complete immediate haemostasis in 92.5% (37/40) and were immobilised with a compression bandage for only four hours. In the Proglide group, one arteriovenous fistula was observed and had to be treated by vascular surgery. The overall duration of stay on an intensive care unit was significantly reduced in the Proglide group (59.4±48.9 hours vs. 84.6±59.5 hours, p<0.005).

CONCLUSIONS

Using a suture-mediated closure device for the femoral vein after percutaneous MitraClip implantation is feasible and safe. This allows earlier patient mobilisation and may reduce post-interventional duration of stay on an intensive care unit.

4-French-compatible endovascular material is safe and effective in the treatment of femoropopliteal occlusive disease: results of the 4-EVER trial

PURPOSE

To report the 1-year results of a prospective multicenter trial to evaluate the safety and efficacy of treating symptomatic femoropopliteal occlusive disease using 4-F-compatible materials and no closure device.

METHODS

The non-randomized 4-EVER trial (4-F endovascular treatment approach to infrainguinal disease) was conducted at 5 European hospitals (ClinicalTrials.gov identifier NCT01413139). The protocol mandated the use of only 4-F sheaths, self-expanding nitinol stents (Astron Pulsar or Pulsar-18 stent), and balloons from a single manufacturer. Between June 2010 and June 2011, 120 symptomatic patients (82 men; mean age 71±9.7 years, range 47-90), primarily claudicants, treated for 120 femoropopliteal lesions (>90% TASC A/B) were enrolled. The mean lesion length was 71.0±45.9 mm. Follow-up evaluations were scheduled on day 1 and at 1, 6, 12, and 24 months. A duplex ultrasound was performed on all follow-up visits to determine vessel patency (primary outcome measure at 1 year), and biplanar radiography was performed at 12 and 24 months to assess stent fracture.

RESULTS

Stents were successfully implanted in all patients: an Astron Pulsar stent in 70 (58.3%) lesions and a Pulsar-18 stent in 46 (38.3%); 4 (3.3%) patients had both stents implanted for flow-limiting dissection after predilation. No closure devices were used; the mean manual compression time was 8.1 minutes (2-15). Four (3.3%) patients developed significant hematoma at the puncture site, but none required surgical repair. The overall 12-month primary patency rate was 81.4%: 85.2% for the Astron Pulsar and 73.4% for the Pulsar-18 (p=0.236). Freedom from target lesion revascularization at 12 months for the entire cohort was 89.3%.

CONCLUSION

Compared to published historical data for superficial femoral artery type A/B lesion stenting using 6-F devices, the 4-F devices applied in this trial showed similar patency at 12 months, fewer access site complications, and shorter manual compression times, supporting the supposition that 4-F endovascular treatment is safe and effective.

Incidence and correlates in the development of iatrogenic femoral pseudoaneurysm after percutaneous coronary interventions

OBJECTIVE

We aimed to identify the correlates in the development of post-percutaneous coronary intervention (PCI) iatrogenic femoral pseudoaneurysm (IFP).

BACKGROUND

IFP is one of the more common vascular complications of PCI.

METHODS

From February 2008 to June 2012, 10,169 consecutive patients who underwent PCI were retrospectively studied. Patients who developed postprocedural IFP were identified at a single, large tertiary PCI center.

RESULTS

One hundred thirty-nine patients developed IFP (1.38%) and were compared to the cohort that did not. Baseline characteristics were comparable, although patients in the IFP group were older and had a higher incidence of insulin-requiring diabetes mellitus and chronic renal insufficiency (68.4 ± 12.9 vs. 65.4 ± 12.3 years, P = 0.004; 23.9% vs. 14.6%, P = 0.002; and 26.6% vs. 17.3%, P = 0.004, respectively). The non-IFP group had more men and a higher use of vascular closure devices, respectively (64.7% vs. 49.6%, P < 0.001; and 54.1% vs. 26.5%, P < 0.001). There was no significant difference in the use of dual antiplatelet or anticoagulation therapies between the 2 cohorts. Univariable correlates for the development of IFP were female gender, insulin-requiring diabetes mellitus, chronic renal insufficiency, and use of manual compression to achieve hemostasis. On multivariable analysis, the successful deployment of vascular closure device for hemostasis reduced the occurrence of IFP (odds ratio 0.31, 95% confidence interval 0.21-0.46, P < 0.0001).

CONCLUSION

The development of IFP following PCI is not uncommon and the appropriate use of vascular closure devices to achieve hemostasis should be encouraged to minimize this vascular complication.

The use of vascular closure devices and impact on major bleeding and net adverse clinical events (NACEs) in balloon aortic valvuloplasty: a sub-analysis of the BRAVO study

OBJECTIVE

To determine the impact of suture-mediated vascular closure devices (VCDs) on net adverse clinical events (NACEs) after balloon aortic valvuloplasty (BAV).

BACKGROUND

Ischemic and bleeding complications are common following transfemoral BAV; however, previous studies have been single center and limited by varying definitions of major bleeding.

METHODS

The Effect of Bivalirudin on Aortic Valve Intervention Outcomes (BRAVOs) study was a retrospective observational study conducted at two high-volume academic centers over a 6-year period designed to compare the effect of bivalirudin versus unfractionated heparin. This is a subanalysis of 428 consecutive patients who underwent BAV (with 10-13 French sheaths) to compare the effect of hemostasis with VCDs versus manual compression utilizing standardized definitions. NACE was defined as the composite of major bleeding and major adverse clinical events (MACEs). All events were adjudicated by an independent clinical events committee who were blinded to antithrombin use.

RESULTS

Preclosure was performed in 269 (62.8%) of patients. While bivalirudin was used more frequently in those with pre-closure (60.6% vs. 37.7%, P < 0.001), a history of prior BAV (11.1% vs. 3.6%, P = 0.04) and peripheral vascular disease (30.7% vs. 19.7%, P = 0.01) was more common in those not undergoing preclosure (n = 159, 37%). Other clinical and demographic features were well balanced between groups. Vascular closure was associated with a significant reduction in NACE (24.5% vs. 10.0% P < 0.001). Results remained significant after adjusting for baseline differences and bivalirudin use (OR 0.38, 95% CI: 0.21-0.68; P = 0.001).

CONCLUSIONS

Our study suggests that suture-mediated vascular closure is associated with a substantial reduction in NACE after transfemoral BAV. Large randomized clinical trials should be conducted to confirm our results.

Arteriotomy closure device safety after percutaneous coronary intervention in the direct thrombin inhibitor era: a comparative study

OBJECTIVES

To investigate the safety and risk of vascular complications of arteriotomy closure devices (ACD) with the direct thrombin inhibitor bivalirudin in patients undergoing percutaneous coronary intervention (PCI).

BACKGROUND

ACDs and manual compression have been shown to have a similar risk of complications in the setting of PCI with heparin ± glycoprotein (GP) IIb/IIIa inhibitor usage. In many centers bivalirudin is becoming the most frequent type of anticoagulation used during PCI. We sought to determine the risk of vascular complications using Angio-Seal, Perclose, and manual compression for groin hemostasis using predominantly bivalirudin.

METHODS

Our institution's interventional database retrospectively identified 14,354 consecutive patients undergoing PCI from 2000 to 2008. Patients were grouped by the adjunctive anticoagulation used (bivalirudin vs. heparin + GP IIb/IIIa inhibitors) as well as ACD employed. The incidence of complications was evaluated using multivariable analysis to account for baseline differences between groups.

RESULTS

Patients undergoing PCI with adjunctive bivalirudin had significantly fewer complications overall, regardless of closure method (2.9% vs. 8.7%, P < 0.001). The Perclose group had significantly fewer complications than the Angio-Seal and manual compression groups (3.9% vs. 5.6% vs. 9.0%, P < 0.001) respectively; the Angio-Seal group had significantly fewer complications than manual compression. Multivariable analysis also identified age ≥ 65, female gender, BMI ≤ 26, and operator as independent predictors of complications.

CONCLUSIONS

The use of adjunctive bivalirudin during PCI was associated with fewer vascular complications. In addition, the Perclose and Angio-Seal devices had significantly fewer complications than manual compression and women ≥ 65 are at highest risk.

Arterial thrombosis after using Angio-Seal

Percutaneous closure systems of arterial puncture sites are being used more and more in modern endovascular practice. In this article, we report five cases of thrombotic complications following Angio-Seal deployment which required to be treated in our department between June 2004 and January 2006. We carried out a computerized literature review using "vascular closure" as a keyword and elected 106 articles published between 1992 and 2007. The analysis of this literature review showed that the rate of percutaneous closure complications was similar to the rate of manual compression complications, which is still the reference method. The complications associated with the use of these systems were more complex and more often required surgical repair. The severity and frequency of these complications differ based on the type of closure systems. The vascular surgeon in charge must have a good knowledge of these systems and of the complications each of them entails to be able to treat them in the most appropriate way.

The AmBulatory Closure Device Percutaneous Intervention (ABCD-PCI) study: a single-center experience

The AmBulatory Closure Device Percutaneous Intervention (ABCD-PCI) study is a multicenter randomized prospective controlled trial evaluating the safety of and patient satisfaction with same-day discharge following ambulatory percutaneous intervention with a closure device. This article reviews the findings from a single center, Baylor Jack and Jane Hamilton Heart and Vascular Hospital, from October 2008 through April 2010, with 23 patients in the same-day discharge group and 21 patients in the next-day discharge group. There were no differences between the groups in demographic or procedure characteristics. Outcomes were measured by a questionnaire and 7-day and 30-day follow-up phone calls. Results showed that same-day discharge after percutaneous intervention with a closure device is as safe as next-day discharge. However, there was a trend for a higher comfort level among patients in the next-day discharge group.

Safety and efficacy of femoral artery closure with the FemoSeal® device after coronary angiography using a 7 French sheath

Post-cardiac catheterization femoral artery hemostasis can be accomplished with several mechanisms, including the FemoSeal® hemostasis device which has been designed and approved for closure of 6 French (F) arterial puncture sites. The aim of this study was to investigate whether the FemoSeal® vascular closure device can effectively and safely seal 7F arterial puncture sites after diagnostic and interventional cardiac catheterizations.

Femoral artery puncture sites of 50 consecutive patients undergoing cardiac catheterization were closed with the FemoSeal® vascular closure device, according to the manufacturer’s instructions. Efficacy endpoints were time to hemostasis and successful ambulation. Safety endpoints included bleeding complications, vessel occlusion and pseudoaneurysms.

Mean time to hemostasis was 57.8±26.3 seconds (0-125 seconds). Hemostasis was achieved in 100 percent of the 50 patients. One patient suffered minor bleeding the next day, i.e. local hematoma.

This clinical study demonstrates that the FemoSeal® vascular closure device, initially approved for closure of 6F arterial puncture sites, shows promising efficacy and safety to seal a larger (7F) femoral arterial puncture sites after diagnostic and interventional cardiac catheterizations.

Effect of experience on results of transcatheter aortic valve implantation using a Medtronic CoreValve System

Outcome after transcatheter aortic valve implantation (TAVI) depends on the patient risk profile, operator experience, progress in technology, and technique. We sought to compare the results of TAVI during the initiation phase and after certification to perform TAVI with the Medtronic CoreValve System without proctoring. A total of 165 consecutive patients was categorized into a first cohort of 33 patients treated before certification (November 2005 to December 2007) and a second cohort of 132 patients treated after certification (January 2008 to October 2010). The study end points were selected and defined according to the Valve Academic Research Consortium recommendations. Compared to cohort 2, the patients in cohort 1 more frequently had New York Heart Association class III-IV (100% vs 71%, p <0.001), hypertension (67% vs 39%, p = 0.004), and aortic regurgitation grade III-IV (46% vs 22%, p = 0.006) before TAVI. Over time, the patients in cohort 2 more frequently underwent a truly percutaneous approach (98% vs 82%, p = 0.002) without circulatory support (96% vs 67%, p <0.001) but with more concomitant percutaneous coronary intervention (11% vs 0%, p = 0.042) than the patients in cohort 1. They also more often received a 29-mm prosthesis (72% vs 24%, p <0.001), required less postimplantation balloon dilation (10% vs 27%, p = 0.008), and had less aortic regurgitation grade III-IV after TAVI (12% vs 30%, p = 0.010). The clinical outcome showed a nonsignificant reduction in the combined safety end point (30% to 17%) but a significant reduction in cerebrovascular events (21% to 7%, p = 0.020) and life-threatening bleeding (15% to 5%, p = 0.044) in cohort 2. However, the reduction in overall bleeding and vascular complications (25% and 14%, respectively) was not significant. In conclusion, TAVI became significantly less complex and was associated with better results over time but remained associated with a high frequency of periprocedural major cardiovascular complications.

Cardio-respiratory exercise testing early after the use of the Angio-Seal system for arterial puncture site closure after coronary angioplasty

AIMS

The vascular closure device (VCD) Angio-Seal is an easy-to-use system for the closure of arterial puncture sites after percutaneous coronary intervention (PCI), and allows for early mobilisation of the patient. However, little data are available about exercising early after the use of VCD's in PCI patients.

METHODS AND RESULTS

A total of 230 consecutive patients were screened. Of these, 45 (20%) were excluded due to the inability to perform exercise testing, or anatomical conditions which prevented the insertion of a VCD. The 185 remaining patients (139 male, mean age 68 ± 12 years) received Angio-Seal after PCI. After four hours, 30 patients (16%) showed a small local haematoma, 11 patients (6%) complained about minor -and one patient (0.5%) about strong- groin pain. There were no major bleeding complications, six pseudo-aneurysmata, and one arterio-venous fistula. Overall, nine patients (6%) showed moderate to severe groin problems. Patients without major complications underwent bicycle cardiopulmonary exercise testing the subsequent day. Exercise testing was performed up to 136 ± 60 W in 176 patients (94%). Maximum workload was 104 ± 33 W, peak oxygen consumption 17.6 ± 5.1 ml/min/kg, and oxygen consumption at the anaerobic threshold 15.4 ± 4.2 ml/min/kg. After exercise testing there were no cardiovascular complications noted.

CONCLUSIONS

In patients receiving VCD after PCI, exercise testing above the anaerobic threshold was feasible after Angio-Seal deployment in those patients with no complications after the use of the device.

Cardiva Catalyst II vascular access management device in percutaneous diagnostic and interventional procedures with same-day discharge (Catalyst II trial)

PURPOSE

To present a prospective, single-center trial of the Cardiva Catalyst II, a vascular closure device that provides temporary hemostasis after the procedure and is removed under manual compression, leaving no material behind.

METHODS

During a 16-month period between April 2008 and July 2009, 400 procedures (100 interventions, 300 diagnostic procedures) were performed on 351 nonconsecutive patients (185 men; mean age 60.2 ± 12.0 years, range 27-93). All interventions were performed utilizing bivalirudin for anti-thrombin therapy. Initial follow-up was done at a mean 1.3 ± 0.7 days after the index procedure in all patients. Final follow-up, for diagnostic procedures as well as interventions, was performed at a mean 15.4 ± 7.1 days. The primary and secondary endpoints were the rate of major and minor vascular complications, respectively.

RESULTS

Successful deployment of the device was reported in 397 (99.3%) procedures, which were primarily in retrograde fashion (97.0%) from the right groin (92.5%). In most cases (309, 77.2%), a 5-F sheath was used. A major vascular complication occurred after 1 intervention; none was noted after diagnostic procedures. Minor vascular complications were recorded after 2 interventions and 5 diagnostic procedures. Overall vascular complication rates were 0.25% for major sequelae and 1.75% for minor events. Mean time to discharge after diagnostic procedures was 145.0 ± 21.2 minutes versus 295.1 ± 44.1 minutes after interventional procedures (p < 0.05). There was no death, stroke, myocardial infarction, or urgent hospital transfer in the study cohort.

CONCLUSION

Cardiva Catalyst is safe and effective device in achieving local hemostasis after percutaneous diagnostic procedures and interventions performed under bivalirudin anticoagulation. The use of this device with an appropriate protocol facilitates same-day discharge.

Safety and efficacy of femoral vascular closure devices in patients undergoing primary percutaneous coronary intervention for ST-elevation myocardial infarction

BACKGROUND

The use of vascular closure devices (VCDs) for the reduction of access site complications following percutaneous coronary intervention (PCI) remains controversial. Patients undergoing primary PCI for acute ST-segment elevation myocardial infarction (STEMI) are at high risk of femoral artery complications. A lack of information exists regarding the use of VCDs in this group of patients because they have been routinely excluded from randomized trials. This study sought to evaluate the safety and efficacy of the routine use of VCDs after primary PCI.

METHODS

A total of 558 consecutive patients undergoing primary PCI for STEMI via femoral route were studied for in-hospital outcomes through a prospective registry from January 2003 to December 2008. The primary end point was the presence of major vascular complication (MVC) defined as a composite of fatal access site bleeding, access site complication requiring interventional or surgical correction, or access site bleeding with ≥3 g/dL drop in hemoglobin or requiring blood transfusion.

RESULTS

Of the total patients, 464 (83.2%) received a VCD; and manual compression was used in 94 patients (16.8%). Major vascular complication occurred in 5.2% of patients. The risk of MVC was significantly lower with VCDs compared with manual compression (4.3% vs 9.6%, P = .036). Multivariable logistic regression analysis determined that VCD use remained an independent predictor of lower rate of MVC (odds ratio 0.38, 95% CI 0.17-0.91).

CONCLUSIONS

The use of VCDs in patients undergoing primary PCI for STEMI is safe and is associated with lower rates of MVC compared with manual compression.

Vascular closure devices in acute coronary syndromes: from arbitrary to a necessity?

Vascular closure devices (VCDs) were initially developed to improve access site hemostasis and allow for earlier ambulation in patients undergoing diagnostic catheterization and percutaneous coronary intervention (PCI). Though initially thought to be beneficial, large meta-analysis has shown conflicting data regarding whether VCDs alter access site bleeding in a variety of clinical settings. One area of particular interest for the adoption of VCDs has been in the setting of acute coronary syndromes (ACS) in which multiple antiplatelet strategies are often employed leading to a high risk of bleeding. Bleeding in ACS has been shown to be a powerful independent predictor of 30-day mortality. Recently, investigators have reported that VCDs reduce access site bleeding in the setting of ACS. In our review, we use several selected representative clinical trials to provide a historical account for the use of VCDs. We also provide for a review of data as it relates to access site bleeding in ACS along with analysis showing that VCDs may potentially provide for reductions in bleeding and vascular complications in patients with ACS undergoing PCI.

Meta-analysis of randomized trials on the efficacy of vascular closure devices after diagnostic angiography and angioplasty

BACKGROUND

The aim of this meta-analysis was to evaluate the safety and efficacy of vascular closure devices (VCDs).

METHODS

This meta-analysis was performed in accordance with the Cochrane Handbook for Systematic Reviews.

RESULTS

The literature search yielded 31 prospective, randomized studies including 7,528 patients who were randomized to VCDs or manual/mechanical compression after diagnostic angiography and/or endovascular procedures. Most of these studies have excluded patients at high risk of puncture site complications. Meta-analysis showed similar results in the study groups in terms of groin hematoma, bleeding, pseudoaneurysm, and blood transfusion. Lower limb ischemia and other arterial ischemic complications (0.3% vs 0%, P = .07) as well as need of surgery for vascular complications (0.7% vs 0.4%, P = .10) were somewhat more frequent with arterial puncture closure devices. The incidence of groin infection was significantly more frequent with VCDs (0.6% vs 0.2%, P = .02). The use of VCD was uniformly associated with a significantly shorter time to hemostasis. Such differences where more evident in patients undergoing percutaneous coronary intervention, whereas these methods were associated with similar rates of adverse events among patients undergoing diagnostic coronary angiography.

CONCLUSIONS

The use of VCDs is associated with a significantly shorter time to hemostasis and thus may shorten recovery. However, the use of VCDs is associated with a somewhat increased risk of infection, lower limb ischemia/arterial stenosis/device entrapment in the artery, and need of vascular surgery for arterial complications. Further studies are needed to get more conclusive results, particularly in patients at high risk of femoral puncture-related complications.
