Impella support for cardiogenic shock and high-risk percutaneous coronary intervention: A single-center experience

Impella-Driven High-Risk Percutaneous Coronary Intervention: A Novel, Single Non-Surgical-Centre Case Report

Complex percutaneous coronary intervention (PCI) procedures have been routinely performed in non-surgical centres in the UK for more than two decades. These procedures follow strict guidelines and recommendations by the British Cardiovascular Intervention Society to ensure a more effective running of PCI programs. Even more so, expected guiding principles necessary for the safe optimisation of complex PCI procedures have also been created.  An 81-year-old male was admitted with non-ST-elevation myocardial infarction (NSTEMI) and severely impaired left ventricle ejection fraction (LVEF; 26% according to the cardiac MRI report). Angiogram findings revealed severe multiple-vessel coronary artery disease affecting the following arteries: right coronary artery (RCA), left anterior descending artery (LAD), left circumflex artery (LCx), and intermediate artery (IM). There was also severe disease in the distal left main stem (LMS) bifurcation extending to the ostia of the LAD, LCx, and IM branches. Following a multidisciplinary meeting, the patient underwent Impella-supported high-risk PCI (complex PCI) using the DK crush technique with no peri- and post-procedure complication and a significant LV function improvement (45-49%). This is the first known case of this procedure performed at the Royal Cornwall Hospital in Treliske (RCHT), Truro, Cornwall. This case report highlights that when the decision to choose between coronary artery bypass graft (CABG) and PCI is not straightforward following an individualised risk-stratification scoring system analysis and in the setting of patient comorbidities, a high-risk PCI supported with the Impella device is a suitable alternative with promising short-term and long-term outcomes.
