Safety and feasibility of a novel total percutaneous post-closure technique after bedside Impella decannulation in patients with cardiogenic shock.

OBJECTIVES

The Impella (Abiomed) is a widely used percutaneous mechanical circulatory support device for high-risk percutaneous coronary intervention in patients with cardiogenic shock. This study aimed to determine the safety and feasibility of a non-angio-guided post-closure approach using the Perclose ProGlide (Abbott) to decannulate the Impella in the intensive care unit.

METHODS

This retrospective study included consecutive patients who were successfully weaned from mechanical circulatory support using the Impella device between April 2019 and April 2022 at Hamamatsu University School of Medicine. Fifteen patients underwent complete post-closure of the femoral artery access sites at the bedside. Technical success of the post-closure hemostasis technique was defined as no evidence of bleeding or additional medical procedures after manual compression. The safety endpoints comprised the Valve Academic Research Consortium-3 and Bleeding Academic Research Consortium criteria.

RESULTS

All patients achieved successful hemostasis with this novel technique without surgical conversion. There was no significant bleeding; however, procedure-related vessel occlusion was observed in 1 patient who was recanalized with balloon angioplasty.

CONCLUSIONS

Bedside post-closure using the Perclose ProGlide device is a safe and feasible alternative to manual compression and surgical removal of the Impella device with low bleeding or vascular complications rates.
