Towards the lumen, loss of alignment with the adjacent wall;
NIH has the same intensity in vessels of different sizes, with greater impact on small-caliber ones,which respond with greater lumen loss than larger vessels.
Late lumen loss was significantly lower in the DEB 0.03± 0.48 mm vs. 0.74± 0.86 mm; p 0.002 group.
At the angiographic follow-up, obtained in 94% of patients,late lumen loss was lower in the DEB group 0.18± 0.45 mm vs. 0.72± 0.55 mm; p 0.001.
However, late lumen loss 0.04 vs. 0.5 mm vs. 0.14± 0.5 mm; p 0.14 and binary restenosis 4.7% vs. 9.5%, p 0.22 were low, and were similar between groups.
DEB studies in animal models showed reduction of neointimal hyperplasia area on the order of 60%, with significant reduction of stenosis diameter and late lumen loss.
The outcomes analyzed were intra-stent late lumen loss primary endpoint, and binary restenosis and MACE rates secondary endpoints at 6 months.
The stents reduced the immediate elastic recoil and negative vessel remodeling,physical phenomena that are responsible for two thirds of the coronary lumen loss after balloon PCI.
The outcomes analyzed were late lumen loss at a 6 month angiographic evaluation primary endpoint and MACE and binary restenosis rates at 12 months secondary endpoints.
The use of DEB was also associated with lower rates of restenosis in the segment RR 0.28; 95% CI: 0.14-0.58; p< 0.001 andlower late lumen loss mean difference, -0.38 mm; 95% CI: -0.60 to -0.15 mm; p 0.001.
The primary endpoint was late lumen loss, assessed on an angiographic follow-up at 6 months, and the secondary endpoints were binary restenosis and MACE rates at 6 months.
It is important to note that the paclitaxel stent used in that study which is different from the one used in the PAINT presented a high late lumen loss, indicating a worse than expected efficacy for a drug-eluting stent.
At 6 months, the angiography showed that the late lumen loss measured 0.03± 0.48 mm vs. 0.74± 0.86 mm p 0.002 and that the binary restenosis rate was 5% vs. 43% p 0.002, respectively.
At follow-up, percent diameter stenosis and minimal lumen diameter were not different among groups,at the same time in-stent late lumen loss was significantly lower in groups 1 and 2 than in the control group 3 p 0.027.
The endpoints analyzed were: late lumen loss in the treated segment after 6 months primary endpoint and binary restenosis at 6 months, and major adverse cardiovascular events MACE at 12 months secondary endpoints.
A study by Costa et al., which included 30 patients with angiographic study protocol at six months,showed late lumen loss of 1.05± 0.77 mm in bypass grafts n 16 and 0.95± 0.66 mm n 14 in native vessels treated with the MGuard stent.
The primary outcome assessed was late lumen loss at 6 months, and the secondary outcome was a combination of cardiac death, acute myocardial infarction AMI attributed to the target vessel, or target lesion revascularization.
In this non-inferiority trial that featured late loss as a primary endpoint, the everolimus-eluting stent was superior to the paclitaxel-eluting stent late lumen loss of 0.11± 0.27 mm vs. 0.36± 0.39 mm at 6 months; P< 0.0001.
Individuals were included, andthe analyzed outcomes were: Late lumen loss at 6 months primary endpoint, and rate of binary restenosis and MACE after 6 months, 1 year, and 3 years secondary endpoints.
Preclinical and randomized studies consistently demonstrate that paclitaxel, in a matrix of soluble additives attached to the balloon,reduces neointimal formation, late lumen loss, restenosis, and target vessel revascularization in patients with restenotic lesions.
The outcomes assessed at 6 months were intra-stent restenosis and late lumen loss primary endpoints, and the need for target lesion revascularization, stent thrombosis, and a new episode of acute coronary syndrome secondary endpoints.
Similar observations for the population of ACS have been published previously, suggesting that, for the treatment of STEMI, all first- and second-generation DES show similar results,notwithstanding higher late lumen loss, restenosis and thrombosis rates for first-generation DES.
Patients treated with DEB had a more favorable outcome;with late lumen loss at 6 months of 0.16± 0.38 mm and restenosis rate of 6%, whereas those who required implantation of BMS had a luminal loss of 0.62± 0.73 mm and a restenosis rate of 45.
In patients submitted to percutaneous transluminal coronary angioplasty in natural coronary arteries with reference diameter< 2.75 mm, the use of self-expanding DES Sparrow compared with the bare metal version of the same stent,resulted in significant reduction of late lumen loss within eight months after the index procedure.
The preliminary clinical results of the Inspirontm stent INSPIRON I have shown a good angiographic response, with late lumen loss of 0.18 mm; good ultrasonographic response, with percentage neointimal obstruction of 8.2%; and target-vessel revascularization of 0.
Late lumen loss, a procedure applied for years for quantification of neointimal hyperplasia, has become one of the most sensitive and surgeon-independent angiographic evaluations of the effectiveness of coronary stents, both for drug-eluting devices or other types.
In this initial series of 30 patients, neointimal hyperplasia was reduced by roughly 80% with late target vessel lumen loss rate of less than 0.20 mm, that was maintained in serial angiographic assessments during the four years after the initial implant.
At follow-up, late lumen loss LLL, restenosis and NIH area were significantly reduced with SES; also, a 3.5-fold decrease in target lesion revascularization TLR was found in SES compared to BMS, a difference that did not reach statistical significance.
Classically defined as the difference between the minimum lumen diameter MLD obtained immediately after the procedure final MLD and the MLD obtained during follow-up,late lumen loss is an angiographic measure of the absolute degree of vascular restenosis, different from the binary restenosis calculation.
