Abstract

BACKGROUND: Real world safety and effectiveness of MANTA vascular closure device (VCD) for large bore arteriotomy closure after decannulation of mechanical circulatory support (MCS) devices is not known.

METHODS: All consecutive patients who underwent large bore arteriotomy closure with MANTA VCD following decannulation of MCS between February to October 2019 at a large tertiary care academic medical center were included. Safety and effectiveness of MANTA VCD was assessed on immediate post-closure angiogram for 23 access sites, and immediate post-closure duplex arterial ultrasound or manual vascular examination for 1 access site each. Technical success was defined as achievement of arteriotomy closure in absence of major bleeding or access site endovascular or surgical intervention.

RESULTS: A total of 25 MANTA VCD were placed in 22 unique patients by 7 different operators. A 14 Fr or 18 Fr MANTA VCD was used in 15 (60%) and 10 (40%) of deployments, respectively via transfemoral (n = 23, 92%) or transaxillary (n = 2, 8%) access. Technical success was achieved in 24 of 25 (96%) cases. Minor access site bleeding occurred in 3 patients (12%) and failure of MANTA VCD with major access site bleeding occurred in 1 patient (4%) requiring endovascular balloon tamponade. No cases of retroperitoneal bleeding, collagen plug embolization, covered stent placement, or surgical vascular repair were observed.

CONCLUSION: In this single center experience, the use of MANTA VCD for large bore arteriotomy closure following percutaneous decannulation of MCS devices appears to be safe and effective. Larger multicenter studies of efficacy, safety, and cost-effectiveness are needed.
