Cross\u2010sections were categorized into three groups based on OFDI findings before Jetstream atherectomy: fibrous plaques (FPs), calcified protrusions (CPs), and eruptive calcified nodules (ECNs).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Twenty\u2010seven patients (36 limbs) were enrolled, and 1502 cross\u2010sections were serially analyzed. There were 186 FPs, 753 CPs, and 563 ECNs. The acquired lumen gain after all atherectomy steps was significantly larger in the ECNs group than in the CPs and FPs groups. ECNs had the strongest effect on the variability in the lumen gain. In the effect of wire bias on the degree of debulking, a significant correlation was observed between wire distance and lumen gain in 1.85\u2010 and 2.4\u2010mm BD atherectomy procedures. However, in the 2.4\u2010mm BU procedure, no significant correlation was recorded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Jetstream atherectomy for ECNs can result in greater lumen gain. In the 1.85\u2010 and 2.4\u2010mm BD atherectomy procedures, wire bias may be involved in lumen gain, whereas in the 2.4\u2010mm BU procedure, lumen gain is obtained regardless of wire bias. In Jetstream atherectomy procedures, a detailed assessment using OFDI may contribute to predicting the degree of debulking.<\/jats:p><\/jats:sec><jats:sec><jats:title>Trial
