Abstract
BACKGROUND The use of poly-l-lactide acid-based bioresorbable scaffolds is limited in daily clinical practice because of safety concerns and lack of physiological benefit. Magnesium-based bioresorbable scaffold (MgBRS) presents a short resorption period (<1 year) and have the potential of being thromboresistant and exhibiting early restoration of vasomotor function. To date, however, no randomized clinical trial has investigated the performance of MgBRS. Therefore, this study aimed to compare the in-stent/scaffold vasomotion between MgBRS and permanent metallic sirolimus-eluting stent (SES) at 12-month follow-up in ST-segment-elevation myocardial infarction patients. METHODS This investigator-driven, multicenter, randomized, single-blind, controlled trial randomized ST-segment-elevation myocardial infarction patients 1:1 to SES or MgBRS at 11 academic centers. The primary end point was the rate of increase (≥3%) after nitroglycerin in mean lumen diameter of the in-stent/scaffold segment at 12 months with superiority of MgBRS over SES in the as-treated population. The main secondary end points included angiographic parameters of restenosis, device-oriented composite end point, their individual components, and device thrombosis rate. Besides, endothelial-dependent vasomotor response to acetylcholine (ie, endothelial function) was also assessed in a subgroup of patients (n=69). RESULTS Between June 2017 and June 2018, 150 ST-segment-elevation myocardial infarction patients were randomized (MgBRS, n=74; SES, n=76). At 1 year, the primary end point was significantly higher in the MgBRS arm (56.5% versus 33.8%; P=0.010). Conversely, late lumen loss was significantly lower in the SES group (in-segment: 0.39±0.49mm versus 0.02±0.27mm, P<0.001; in-device: 0.61±0.55mm versus 0.06±0.21mm; P<0.001). The device-oriented composite end point was higher in the MgBRS arm driven by an increase in ischemia-driven target lesion revascularization rate (12[16.2%] versus 4[5.2%], P=0.030). Definite thrombosis rate was similar between groups (1[1.4%] in the MgBRS arm versus 2[2.6%] in the SES group; P=1.0). Endothelial function assessment at device segment evidenced a more pronounced vasoconstrictive response to maximal dose of acetylcholine in the MgBRS arm (-8.3±3.5% versus -2.4±1.3% in the SES group, P=0.003). CONCLUSIONS When compared to SES, MgBRS demonstrated a higher capacity of vasomotor response to pharmacological agents (either endothelium-independent or endothelium-dependent) at 1 year. However, MgBRS was associated with a lower angiographic efficacy, a higher rate of target lesion revascularization, without thrombotic safety concerns.

Abstract
In patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI), lack of ST-segment resolution (STR) is associated with poor prognosis at short- and long-term follow-up. The aim of this study was to evaluate the role of STR on very long-term outcomes in patients with STEMI treated with pPCI included in the EXAMINATION (Evaluation of the Xience-V Stent in Acute Myocardial Infarction) trial. Patients were stratified according to the presence of STR < 50% and STR < 70% at the 30-minute post-pPCI electrocardiogram. Primary end point was the patient-oriented composite endpoint (POCE) of all-cause death, any myocardial infarction, or any revascularization at 5-year follow-up. Both baseline and post-PCI 30-minute electrocardiograms were available for STR assessment in 1,351 patients. Of these patients, 228 (16.9%) and 500 (37.0%) exhibited STR < 50% and STR < 70%, respectively. At 5-year follow-up, the POCE was observed more frequently in patients with STR < 50% (hazard ratio [HR] 1.556; 95% confidence interval [CI] 1.194 to 2.027; p <0.001) and in patients with STR < 70% (HR 1.460, 95% CI 1.169 to 1.824, p <0.001) compared with patients with STR > 50% and STR ≥ 70%, respectively. In both cases, this difference was mainly driven by a significant increase in the rate of all-cause death and any revascularization. After multivariable adjustment, STR < 70%, but not STR < 50%, resulted as a 5-year independent predictor of POCE (adjusted HR 1.338, 95% CI 1.008 to 1.778, p = 0.044). In conclusion, in patients with STEMI, the evaluation of 70% STR after pPCI provides independent prognostic information at 5-year follow-up and it can be used to identify patients at high risk of very long-term cardiovascular events.

Abstract
BACKGROUND Left main coronary artery (LMCA) stenting is an evolving technique. Whether follow-up computed tomography angiography (CTA) might have clinical impact in these patients is controversial. The aim of present study is to compare clinical outcomes of patients with LMCA stenting followed with CTA versus patients with conventional clinical follow-up. METHODS From 2003 to 2014 all consecutive patients with unprotected LMCA stenosis treated with single DES implantation were prospectively included. Since 2009 all patients underwent CTA at 6-month after LMCA stenting. Therefore, the non-CTA group included all patients treated from 2003 to 2009 and the CTA group included patients treated from 2009 to 2014. Patients with 6-month cardiac events, renal dysfunction or atrial fibrillation were excluded. All patients underwent at least 2-year clinical follow-up. The primary endpoint was a composite of cardiac death, nonfatal myocardial infarction, and LMCA revascularization. RESULTS A total of 236 patients were included (119 in the non-CTA and 117 in the CTA group). Nine event-free patients presented with in-stent restenosis as assessed by CTA at 6 months; 5 had angiographic confirmation and were revascularized. At 2 years, the primary end-point was observed in 15.1% and 7.3% of patients of the non-CTA and CTA groups, respectively (P=0.07). All-cause mortality was higher in the non-CTA group (8.4% vs. 2.6%; P=0.05). Euroscore and CTA were found independent predictors of the primary end-point in the multivariate analysis. CONCLUSIONS Elective 6-month CTA after LMCA stenting is associated with better outcomes compared to conventional clinical follow-up.

Abstract
OBJECTIVES The aim of this study was to compare the efficacy of amphilimus-eluting stents (AES) with that of everolimus-eluting stents (EES) in patients with diabetes mellitus (DM). BACKGROUND The AES is a polymer-free drug-eluting stent that elutes sirolimus formulated with an amphiphilic carrier from laser-dug wells. This technology could be associated with a high efficacy in patients with DM. METHODS This was a multicenter, randomized, noninferiority trial. Patients with DM medically treated with oral glucose-lowering agents or insulin and de novo coronary lesions were randomized in a 1:1 fashion to AES or EES. The primary endpoint was the neointimal (NI) volume obstruction assessed by optical coherence tomography at 9-month follow-up. RESULTS A total of 116 lesions in 112 patients were randomized. Overall, 40% were insulin-treated patients, with a median HbA1c of 7.3% (interquartile range: 6.7% to 8.0%). The primary endpoint, NI volume obstruction, was 11.97 ± 5.94% for AES versus 16.11 ± 18.18% for EES, meeting the noninferiority criteria (p = 0.0003). Pre-specified subgroup analyses showed a significant interaction between stent type and glycemic control (p = 0.02), with a significant reduction in NI hyperplasia in the AES group in patients with the higher HbA1c (p = 0.03). By quantitative coronary angiography, in-stent late loss was 0.14 ± 0.24 for AES versus 0.24 ± 0.57 mm for EES (p = 0.27), with a larger minimal lumen diameter at follow-up for AES (p = 0.02), mainly driven by 2 cases of occlusive restenosis in the EES group. CONCLUSIONS AES are noninferior to EES for the coronary revascularization of patients with DM. These results suggest a high efficacy of the AES and may support the potential benefit of this stent in patients with DM.

Abstract
Background—
The main causes of late (>1 month) stent thrombosis (ST) are stent uncoverage, malapposition, and neoatherosclerosis. First-generation drug-eluting stents were associated with higher rate of late ST compared with bare-metal stents (BMS), especially in patients with ST-segment–elevation myocardial infarction. Second-generation everolimus-eluting stents (EES) have shown similar rate of late ST than BMS. The aims of the study are to compare the ratio of uncovered to total struts per cross-section ≥30% and other optical coherence tomographic findings associated with ST between EES and BMS in patients with ST-segment–elevation myocardial infarction at 5 years.
Methods and Results—
One hundred and sixty-nine consecutive event-free patients of the randomized EXAMINATION study (A Clinical Evaluation of Everolimus Eluting Coronary Stents in the Treatment of Patients With ST-Segment Elevation Myocardial Infarction) were screened for optical coherence tomographic imaging at 5 years. Patients with target vessel–related events or life-threatening comorbidities were excluded. Finally, 64 patients (32 EES and 32 BMS) underwent optical coherence tomographic imaging. At 5 years, uncovered struts (4.1% versus 1.0%;
P
<0.01), length of uncoverage (3.4 versus 1.4 mm;
P
=0.02), and ratio of uncovered to total struts per cross-section ≥30% (35.5% versus 9.7%;
P
=0.02) were larger with EES than that with BMS. Malapposed struts (1.2% versus 0.3%;
P
=0.02) and malapposition length (1.3 versus 0.4 mm;
P
=0.06) were also larger with EES. Neoatherosclerotic plaques (16.1% versus 25.8%;
P
=0.35) and macrophage accumulations (19.4% versus 48.4%;
P
=0.02) were numerically more frequent with BMS.
Conclusions—
Despite substantial dropout of patients, the healing pattern in event-free ST-segment–elevation myocardial infarction patients differs between EES and BMS at 5 years. EES presented with larger amount of uncovered and malapposed struts and similar rate of neoatherosclerosis as compared with BMS. The clinical relevance of these findings warrants longer follow-up.

Abstract
AIMS To compare the degree of endothelial dysfunction (ED) in patients treated with everolimus-eluting stent (EES) versus bare metal stent (BMS) implantation. METHODS AND RESULTS This is an observational study. A total of 30 elective patients (15 treated with EES and 15 with BMS) were recruited. All patients underwent coronary angiography and intracoronary acetylcholine (Ach) test at different doses at six months after stent implantation. Quantitative coronary angiography analysis was performed to evaluate the changes in mean luminal diameter (MLD) of the segments distal to the distal stent edge after increasing doses of Ach. Both EES and BMS groups had similar baseline characteristics except for stent length (18.6±2.5 vs. 16.5±2.5 mm; p=0.033) and diameter (3.1±0.2 vs. 3.4±0.3 mm; p=0.007). The vasomotion test showed that EES had 3.14% of MLD decrease after Ach infusion and BMS had 2.35% of vasoconstriction (p=0.62). After adjustment for baseline characteristics, no statistical difference was observed between groups. CONCLUSIONS In our study EES implantation was associated with a low degree of ED and had a similar vasomotion response as compared to BMS. Prospective randomised investigations are warranted to confirm these findings.

Abstract
AIMS Chronic total occlusions (CTO) are the final stage of atherosclerosis. Occluded coronary arteries have large plaque burden and negative remodelling. The aim of this study was to assess lumen and vessel changes of segments located distal to successfully recanalised CTO. METHODS AND RESULTS Ninety-one CTO treated with drug-eluting stents underwent quantitative coronary angiography (QCA) at baseline and at 12-18 months; 31 underwent serial intravascular ultrasound (IVUS) imaging. Angiographic changes were assessed with QCA as differences in minimal, mean and maximal lumen diameter (MinLD, MeanLD and MaxLD, respectively). Vessel changes were assessed with IVUS as changes in plaque and vessel volume. At follow-up, angiographic MinLD increased 23.9% (from 0.88±0.32 to 1.09±0.35 mm; p<0.01), MeanLD 16.4% (from 1.59±0.44 to 1.85±0.45 mm; p<0.01) and MaxLD 11.7% (from 2.39±0.67 to 2.67±0.70 mm; p<0.01). Lumen enlargement was greater in non-restenotic lesions, small lumen area at the end of the index procedure and low LDL-cholesterol levels during the study. By IVUS, lumen volume increased 26.9% (from 108.1±89.2 to 137.3±115.3 mm3; p<0.01), vessel volume increased 12.1% (from 207.1±170.2 to 232.2±196.0 mm3; p<0.01) and plaque volume tended to decrease 3.9% (from 98.9±88.7 to 94.9±89.3 mm3; p=0.07). Small lumen at baseline was related to greater lumen enlargement. CONCLUSIONS Segments distal to recanalised CTO showed a notable lumen and vessel enlargement with a trend toward mild plaque regression. Low LDL-cholesterol levels increase lumen enlargement.

Abstract
BACKGROUND Some modifications introduced in the design of the new generation of drug-eluting stent (DES) to improve their flexibility may entail a reduction in their longitudinal strength. This study sought to evaluate the longitudinal deformation of DESs by multislice computed tomography (MSCT). METHODS This study included DESs that could have been potentially deformed by mechanical actions such as: (1) catheter impingement; (2) postdilation; (3) kissing balloon; and (4) intravascular imaging after implantation. Patients on atrial fibrillation or with overlapping stents were excluded. All patients underwent stent length evaluation by MSCT 9-12 months after implantation. RESULTS Forty-five stents were included: 15 platinum chromium (PtCr-DES), 15 cobalt chromium (CoCr-DES), and 15 stainless-steel (SS-DES). The relative longitudinal deformation by stent type was 6.93 ± 5.82% for PtCr-DES, 6.19 ± 5.79% for CoCr- DES, and 4.03 ± 4.07% for SS-DES (P=.31). Among the mechanical actions studied, only catheter impingement was related to longitudinal stent deformation (P<.01). After adjustment, only catheter impingement (P<.01) and nominal stent length (P=.049) were independently related to longitudinal deformation. There were no stent fractures. CONCLUSIONS Longitudinal deformation of DESs is common in all the studied platforms when subject to longitudinal forces. Guiding catheter impingement is the only mechanical action significantly associated with DES shortening.
