Abstract
- Background: Left main (LM) atherosclerotic lesions affect clinical outcomes. Frequency domain-optical coherence tomography (FD-OCT) allows detailed characterization of non-ostial coronary atherosclerotic lesions. The clinical impact of FD-OCT assessment of LM bifurcation disease on the revascularization decision is unknown.<br />Methods: Patients who underwent FD-OCT assessment to guide management of angiographically intermediate distal LM stenosis were retrospectively selected. The FD-OCT LM criteria for percutaneous or surgical revascularization were: Clinical follow-up was obtained to evaluate the occurrence of target vessel failure (TVF) defined as cardiac death and/or acute myocardial infarction (AMI) not related to other vessel and/or target vessel revascularization.<br />Results: Out of 131 patients underwent FD-OCT assessment of LM, 122 patients (93%) entered the study. Based on FD-OCT features, 58 (48%) patients were conservatively managed, while the remaining 64 (52%) were revascularized by stenting (n=48) or surgery (n=16). After a mean follow-up of 18months, TVF-free survival was not different between patients undergoing conservative management vs. revascularization (HR 0.40, CI 95% 0.10-1.61, P=0.20). Of note, two patients only in the conservative management group had TVF (elective LM stenting, no death or myocardial infarction).<br />Conclusions: This preliminary experience suggests that a FD-OCT based management for patients with angiographically-intermediate LM bifurcation stenosis may help identify patients in whom revascularization could be deferred. Such observation calls for further evaluations by appropriately designed trials.<br /> (Copyright © 2017 Elsevier B.V. All rights reserved.)
