Abstract

Introduction

Patients with coronary chronic total occlusions (CTO) often have concurrent higher-risk anatomy and physiology (significant calcium, left ventricular dysfunction, multivessel disease) that increase their procedural risk. We present a retrospective multicenter case series describing use of the Impella percutaneous ventricular assist device (p-VAD) during CTO PCI.

Methods

We performed a retrospective analysis of self-reported data from five large referral centers from 2013 to 2017 and identified patients that underwent elective, hemodynamically supported CTO PCI with the Impella p-VAD device (2.5 or CP). Preprocedural demographics, procedural invasive hemodynamics and characteristics, and in-hospital outcomes were reported.

Results

About 57 patients (2% of the overall CTO volume of these centers) were included in this retrospective cohort. The primary indication in the majority (78.9%) of cases was chronic angina; in 21.1% the primary indication was for chronic congestive heart failure because of an ischemic cardiomyopathy. The median LVEF was 20% (15%, 30%) and 63.2% were surgical turndowns. Significant proportions of the group underwent multivessel PCI (91.2%), intervention on an unprotected left main or last remaining conduit vessel (35.1%), and/or atherectomy (17.5%). Technical success was 87.7%. In-hospital procedural complications included: vascular injury (5.3%), all-cause death (5.3%), major bleeding (3.5%), stroke (1.8%), and coronary perforation resulting in tamponade (1.8%).

Conclusion

Impella-assisted CTO PCI can be performed with high technical success rates. However, assiduous attention to appropriate case selection is critical, given the periprocedural complication rates reported in this patient population.
