Abstract
VA-ECMO can be lifesaving in cardiogenic shock in children. While surgical vascular repair is the current standard of care for decannulation, it comes with notable risks. We present a series of eight patients who underwent decannulation with a collagen plug-based vascular closure device (MANTA) for the common femoral artery. Seven of the patients were successfully decannulated without access site-related vascular complications. One required conversion to surgical cut-down with arterial repair due to device failure. This series demonstrates the successful use of the MANTA device in percutaneous VA-ECMO decannulation in the pediatric population, while highlighting potential technical challenges for success.

Abstract
BACKGROUND The MANTA vascular closure device (VCD) is a novel collagen plug-based VCD for large bore arteriotomies. The current literature regarding complication rates of this device is quite variable and mostly limited to relatively small case series. METHODS This study is retrospective analysis of the MANTA VCD-related main access site complications according to Valve Academic Research Consortium-2 (VARC-2) criteria during the hospital stay. Particular attention was paid to the detailed analysis of multislice computed tomography with regard to the anatomy of the access vessel and the puncture site itself. RESULTS A total of 524 patients underwent transfemoral transcatheter aortic valve implantation (TF TAVI) including the use of the MANTA device (18F) for percutaneous vascular closure. A group of 22 patients was excluded from the study due to incomplete imaging data. During the study period, we observed 28 major (5.6%) and five minor (1.0%) MANTA device-related vascular complications. There was no patient death related to these adverse events. Female gender, vessel angulation at the puncture site, and at least moderate calcification of the dorsal vessel segment were identified as independent predictors for major complications. CONCLUSIONS The MANTA device is a feasible option for vascular closure of large bore arteriotomies in patients undergoing TF TAVI or other percutaneous transfemoral interventions. Furthermore, we have identified novel predictors for device failure/complications that should be taken into account for selection of the appropriate closure device. To our knowledge, this report is one of the largest case series analyzing the use of the MANTA VCD.

Comparison of Suture-Based and Collagen-Based Vascular Closure Devices for Large Bore Arteriotomies-A Meta-Analysis of Bleeding and Vascular Outcomes. J Cardiovasc Dev Dis 2022; 9:jcdd9100331. [PMID: 36286283 PMCID: PMC9604251 DOI: 10.3390/jcdd9100331] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2022] [Revised: 09/15/2022] [Accepted: 09/27/2022] [Indexed: 01/24/2023] Open
Abstract
BACKGROUND Large bore access procedures rely on vascular closure devices to minimize access site complications. Suture-based vascular closure devices (S-VCD) such as ProGlide and ProStar XL have been readily used, but recently, newer generation collagen-based vascular closure devices (C-VCD) such as MANTA have been introduced. Data on comparisons of these devices are limited. METHODS PubMed, Scopus and Cochrane were searched for articles on vascular closure devices using keywords, ("Vascular closure devices" OR "MANTA" OR "ProStar XL" OR "ProGlide") AND ("outcomes") that resulted in a total of 875 studies. Studies were included if bleeding or vascular complications as defined by Valve Academic Research Consortium-2 were compared between the two types of VCDs. The event level data were pooled across trials to calculate the Odds Ratio (OR) with 95% CI, and analysis was done with Review Manager 5.4 using random effects model. RESULTS Pooled analyses from these nine studies resulted in a total of 3410 patients, out of which 2855 were available for analysis. A total of 1229 received C-VCD and 1626 received S- VCD. Among the patients who received C-VCD, the bleeding complications (major and minor) were similar to patients who received S-VCD ((OR: 0.70 (0.35-1.39), p = 0.31, I2 = 55%), OR: 0.92 (0.53-1.61), p = 0.77, I2 = 65%)). The vascular complications (major and minor) in patients who received C-VCD were also similar to patients who received S-VCD ((OR: 1.01 (0.48-2.12), p = 0.98, I2 = 52%), (OR: 0.90 (0.62-1.30), p = 0.56, I2 = 35%)). CONCLUSIONS Bleeding and vascular complications after large bore arteriotomy closure with collagen-based vascular closure devices are similar to suture-based vascular closure devices.

Abstract
BACKGROUND Mechanical circulatory support (MCS) devices are increasingly used for hemodynamic support in cardiogenic shock or high-risk percutaneous coronary interventions. Vascular complications remain a major source of morbidity and mortality despite technological advances with percutaneous techniques. Little is known about the rates and predictors of vascular complications with large-bore access MCS in the contemporary era. METHODS The study cohort was derived from National Inpatient Sample using data from 2015 to 2019 for cardiac hospitalizations with the use of: intra-aortic balloon pump (IABP) Impella, and/or extracorporeal membrane oxygenation (ECMO). The rates of vascular complications and in-hospital outcomes were analyzed using multivariable logistic regression. RESULTS Of 221,700 hospitalizations with MCS use, the majority had only IABP (68%). The rates of vascular complications were greatest with ECMO (15.8%) when compared with IABP (3.0%) and Impella (5.6%). Among patients with vascular complications, in-hospital mortality was higher with ECMO (56.3%) when compared with IABP (26.2%) and Impella (33.8%). Peripheral arterial disease (PAD) was the strongest predictor of vascular complications, with 10 times higher odds when present (adjusted odds ratio [aOR] 10.96, p < 0.001). In risk-adjusted models, when compared with IABP, the use of Impella (aOR: 1.73, p < 0.001), ECMO (aOR: 5.35, p < 0.001), or a combination of MCS devices (aOR: 3.47, p < 0.001) was associated with higher odds of vascular complications. CONCLUSIONS In contemporary practice, the use of MCS is associated with significant vascular complications and in-hospital mortality. Predictors of vascular complications include larger arteriotomy size, female gender, and peripheral arterial disease. Vascular access management remains essential to prevent major complications.

Iliofemoral tortuosity increases the risk of access site-related complications after aortic valve implantation and plug-based access site closure. CJC Open 2022; 4:609-616. [PMID: 35865026 PMCID: PMC9294987 DOI: 10.1016/j.cjco.2022.03.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2021] [Accepted: 03/15/2022] [Indexed: 11/23/2022] Open
Abstract
Background Access-site-related complications are often related to high-risk anatomy and technical pitfalls and impair the outcomes of transfemoral aortic valve implantations (TAVIs). Calcification and tortuosity are widely recognized risk factors, and their impact on procedural planning is left to the implanting experts’ discretion. To facilitate decision-making, we introduced a quantitative measure for iliofemoral tortuosity and assessed its predictive value for access-site-related vascular and bleeding complications. Methods We performed a single-centre prospective cohort study of consecutive, percutaneous transfemoral TAVI performed between April 2019 and March 2020. Medical history and all-cause mortality were extracted from the electronic patient files. Arterial anatomy and calcifications were evaluated using 3mensio Structural Heart software. The primary outcome was access-site-related vascular or bleeding complications. Results In this elderly, intermediate-risk population, we registered the primary outcome in 43 patients (39%), and major access-site complications in 10 patients (9.2%). Complete hemostasis was achieved in 77 patients (70.6%), by the application of the MANTA plug alone. In the group with access-site-related adverse events, compared with the group without, the tortuosity index was higher median (26% interquartile range [IQR 18%-33%] vs median 19% [IQR 13%-29%], respectively; P = 0.012), as was maximal angulation median (50° [IQR 40°-59°] vs median 43° [IQR 36°-51°], respectively; P = 0.026) were higher. Both variables had a significant effect on our primary outcome, with odds ratios (OR) of 3.1 (tortuosity, P = 0.005) and 2.6 (angulation, P = 0.020). The degree of angulation was a predictor of major complications too (odds ratio 7 [1.4-34.8]; P = 0.017). Conclusions Steeper angles and greater arterial elongation increase the risk of vascular and bleeding complications after femoral TAVI with the utilization of a plug-based closure device.

Abstract
Backgrounds Among vascular closure devices (VCDs), the novel collagen plug-based MANTA VCD is the first designed for large bore percutaneous access. We aimed to assess the features and predictors of access-site vascular complications in an unselected trans-femoral transcatheter aortic valve replacement (TF-TAVR) population. Methods Patients undergoing large bore arteriotomy closure with 18F MANTA VCD following TF-TAVR at a large tertiary care center from September 2019 to January 2021 were prospectively analyzed. Primary Outcome was the MANTA VCD access-site-related complications according to Valve Academic Research Consortium-3 (VARC) definitions. Its incidence and predictors were evaluated. Results Eighty-eight patients (median age 82 years, 48% male, 3.3 median Society of Thoracic Surgeons score) undergoing TF-TAVR were included, mostly (63%) treated with a self-expandable device and with outer diameter sizes varied from 18F to 24-F. MANTA VCD technical success rate was 98%, while 10 patients (11%) experienced MANTA VCD access-site vascular complications which included 8% of minor complications and only to 2% of major events resulting in VARC type ≥2 bleeding. Vessel occlusion/stenosis (60%), perforation (20%), and pseudoaneurysm/dissection/hematoma (20%) occurred, but all were managed without surgical treatment. Independent predictors of failure were age (p = 0.04), minimum common femoral artery diameter (CFA) (p < 0.01), sheath-to-femoral-artery ratio (SFAR) (p < 0.01), and a lower puncture height (p = 0.03). A CFA diameter <7.1 mm with a SFAR threshold of 1.01 were associated with VCD failure. Conclusions In a more comers TF-TAVR population, MANTA VCD was associated with reassuring rates of technical success and major access-site vascular complications. Avoiding lower vessel size and less puncture site distance to CFA bifurcation might further improve outcomes.

Abstract
The MANTA is a new, easy-to-use, collagen plug-based vascular closure device specifically designed for large-bore arteriotomy closure. The authors report on their experience comparing the MANTA device with the Perclose ProGlide technique in patients undergoing transcatheter aortic valve replacement. They found similar rates of success and vascular complications with both devices, suggesting that MANTA is a suitable option for these patients. It remains to be determined whether one device will emerge as the ideal choice for most patients. Device cost is a significant barrier to widespread adoption, but price has decreased recently.

Abstract
This article provides supplementary tables and figures to the research article: Frequency, Impact and Predictors of Access Complications with Plug-Based Large-Bore Arteriotomy Closure - A patient level meta-analysis [1]. The data provide insight in the type and management of access complications related to the plug-based MANTA vascular closure device (VCD) for large-bore catheter-based cardiovascular interventions. Since MANTA is mostly used in transcatheter aortic valve replacement (TAVR) procedures, this article also contains a sub-group analysis on TAVR procedures using contemporary valve-platforms. Further, data describing MANTA hemostasis times and mortality causes are included. For this dataset, individual patient data were derived from a European and a North American device approval study (the Conformite Européene [CE] mark study and the investigational device exemption SAFE-MANTA study [2,3]) in addition to a post-approval registry (the MARVEL registry [4]) covering a total of 891 patients who were enrolled between 2015 and 2019 across 28 investigational sites. Eligibility criteria were most stringent in the SAFE MANTA study (38% of patients) whereas the MARVEL registry applied liberal and only relative exclusion criteria (56% of patients). A total of 78 Roll-in cases (i.e. first or second time operator use of the MANTA VCD) who were excluded from analysis in SAFE MANTA were included in the present to evaluate a potential learning curve effect. Therefore, this dataset reflects the largest study population undergoing arteriotomy closure with the MANTA VCD by operators at various levels of experience, which can be valuable to further build on research regarding percutaneous large-bore arteriotomy management.
