The aim of the study was to identify the predictors of side branch (SB) compromise in severely calcified bifurcation lesions treated with orbital atherectomy (OA).Abstract:
OBJECTIVES The aim of the study was to identify the predictors of side branch (SB) compromise in severely calcified bifurcation lesions treated with orbital atherectomy (OA). BACKGROUND SB compromise remains a major complication of bifurcation lesion percutaneous coronary intervention (PCI). Higher prevalence of lipid-rich plaques and spotty calcification by optical coherence tomography (OCT) and SB ostial stenosis by angiography have been previously suggested as predictors of SB occlusion after main vessel (MV) stenting. METHODS Patients with chronic stable angina and severely calcified bifurcation lesions, in whom provisional stenting strategy was planned, were enrolled in the study. OA was used for lesion preparation in all cases. OCT imaging of the MV was performed before and after stenting. SB compromise was defined as a composite of SB occlusion (TIMI flow grade ≤ 2) and SB intervention after MV stenting. RESULTS Thirty stable CAD patients with 30 severely calcified bifurcation lesions were included in the study. Twelve patients (40%) had a compromised SB after MV stenting. Compromised SB was characterized by a greater angiographic diameter stenosis (55.4 ± 8.1% vs. 35.0 ± 14.4%, P < 0.01) and a smaller minimal lumen diameters (0.79 ± 0.17 vs. 1.12 ± 0.30 mm, P = 0.002) before PCI compared to noncompromised SB. The prevalence of OCT lipid-rich plaques was low and did not differ between the groups (18 vs. 19%, P = 0.68). There was no difference in other OCT plaque characteristics including the presence of spotty calcification. CONCLUSION The severity of SB ostial disease and not MV plaque morphology contributed to SB compromise in severely calcified bifurcation lesions.read more

TL;DR: In this multicenter cohort analysis, patients with severely calcified coronary bifurcation lesions had low rates of MACE and target vessel revascularization at 30 days at rates comparable to non-bifurculation lesions.

TL;DR: The presence of a bifurcating target vessel with moderate/severe calcification is associated with a higher risk of adverse outcomes than either attribute alone, and new approaches are needed to improve outcomes in this subset of patients with complex coronary artery disease.
