Background:
Use of percutaneous mechanical circulatory support has grown exponentially. Vascular complications remain a growing concern and best practices for device removal do not exist. We describe a novel post-closure technique for the next generation Impella CP removal and immediate hemostasis.
Methods:
This study is a single center, retrospective, exploratory analysis of 11 consecutive patients receiving an Impella CP for either high-risk PCI or cardiogenic shock and then referred for post-closure compared to 20 patients receiving manual compression for Impella CP removal between 2017 and 2019.
Results:
Mean age range was 62.7-65.4 years and 50-65% male between groups. Average duration of Impella CP treatment ranged from 3.4 to 5.2 days. Patients referred for post-closure had significantly lower rates of all-cause adverse vascular events (0% versus 40%; n = 0/11 versus n = 8/20; p = 0.01). There was no significant difference in BARC 3 or greater bleeding, transfusion requirement, hospitalization duration or intensive care duration between removal strategies.
Conclusion:
The novel post-closure technique may significantly reduce vascular complications associated with device removal and may improve clinical outcomes for these critically ill patients.
