Clinical expert consensus document on the use of percutaneous left ventricular assist support devices during complex high-risk indicated PCI: Italian Society of Interventional Cardiology Working Group Endorsed by Spanish and Portuguese Interventional Cardiology Societies

Percutaneous coronary intervention (PCI) is establishing as the last remaining revascularization option in an increasing number of patients affected by complex coronary artery disease not suitable for surgery. Over the past decade, percutaneous left ventricular assist device (pLVAD) has increasingly replaced intra-aortic balloon pump to provide hemodynamic support during such non-emergent complex high-risk indicated procedures (CHIP) averting the risk of circulatory collapse and of adverse events in long lasting and/or complicated procedures. This review article aims to report the key factors to define CHIP, to summarize the available pLVAD which have CEmark for temporarymechanical LV support and to discuss the rationale of their use in this subset of patients. Based on the expertise of the Italian Society of Interventional Cardiologyworking group, with the endorsement fromSpanish and Portuguese Society of Interventional Cardiologyworking groups, it will provide several practical suggestions in regards to the use of pLVAD in different clinical CHIP scenarios.
