Purpose of reviewIn spite of the benefits of drug eluting (DES), these advantages were not translated to better outcome when percutaneous coronary interventions (PCI) were compared with coronary artery bypass surgery. PCI strategy allowing stent deployment in all intermediate lesions including small vessels together with DES design may be the reasons of these findings.Recent findingsRecently randomized and observational studies demonstrated using functional flow reserve analysis, residual Syntax score risk, or residual ERACI score after PCI that a reasonably incomplete revascularization was associated with good long-term outcome and low events rate at follow-up. In the ERACI IV study, which included patients with multiple vessel disease and left main, all intermediate lesions and severe lesions in small vessels were excluded from the revascularization strategy, and the 3-year follow-up results showed a remarkable low incidence of death/MI and stroke.SummaryIntermediate stenosis or severe lesions in small vessels should not be incorporated in the PCI strategy in order to define patient clinical cardiac prognosis or completeness of revascularization.
