The Single-Access Technique for Impella Protected Percutaneous Coronary Intervention: A Single-Center Experience

BACKGROUND: In this era of complex high-risk percutaneous coronary intervention (HR-PCI), mechanical support is being increasingly used. Traditionally, mechanical circulatory support with the Impella CP device requires a large-bore arterial access and an additional arterial access for the subsequent coronary intervention. We present a case series of the novel single-access for HR-PCI (SHIP) technique, in which a single arterial access is used for both mechanical support and coronary intervention. We reviewed 35 patients from June 2019 to February 2021 in whom the procedure was successfully employed in all but 1 case. In our case series, this technique appeared to be safe and feasible, and none of our patients suffered any major bleeding or vascular complications. As our experience with the procedure grew, we started employing this technique in patients presenting with ST-segment elevation myocardial infarction and cardiogenic shock. We discuss in detail the nuances of the technique, including troubleshooting, procedural characteristics, and complications, and review the currently available literature.
