Imaging-Guided Deployment of a Balloon-Based Vascular Closure Device in Routine Clinical Practice

Abstract

This study evaluated the feasibility and safety of imaging-guided deployment of a Mynx Control device (Cordis, Miami Lakes, Florida) at the femoral access. A total of 201 Mynx devices were used under imaging guidance in 137 patients (mean age, 64.18 years +/- 13.8; male, 68.6%) between June 2020 and February 2022. A 5-F sheath was used in 176 (87.6%) procedures, a 6-F sheath was used in 17 (8.5%) procedures, and a 7-F sheath was used in 8 (4%) pro-cedures. Indicator errors occurred in 9 (4.5%) procedures. However, technical success was achieved via manipulation under imaging guidance in all procedures. The mean time to hemostasis was 3.3 minutes +/- 0.5, and the clinical success rate was 100%. The mean length of hospital stay was 7 days +/- 7.5. After 4 (2%) procedures, small hematomas reabsorbed spontaneously. Imaging-guided deployment of a Mynx Control device is a feasible and safe option for access site closure. Even after an indicator error, successful hemostasis was achieved via real-time interaction.
