Abstract
OBJECTIVE To assess the effect of manual thrombectomy (MT) on microvascular obstruction (MVO) using cardiac magnetic resonance (CMR) in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI). METHODS AND RESULTS Three hundred and eighty-three patients admitted for STEMI and undergoing CMR fulfilled the inclusion criteria and were categorized into two groups (did or did not undergo MT). The two primary endpoints were the occurrence and extent of MVO, analyzed as a categorical variable and as a semicontinuous variable. Among the 383 patients, 49.1% exhibited MVO. Both the incidence of MVO and the median number of segments presenting with MVO were significantly higher in the MT group than in the no-MT group, (59.5 vs. 38.9%, p < .001) and (1.5 [0;4] vs. 0 [0;2], p < .001). Analysis stratified on coronary thrombus grade showed similar results, only in patients with a high thrombus burden (60.7 vs. 43.5%, p = .004, and 2 [0;4] vs. 0 [0;3], p = .001. When adjusting for baseline differences, MT remained a determinant of MVO occurrence and extent (odds ratio, OR 1.802 [95% confidence interval, CI 1.080-3.009], p = .024) and β = .137, p = .024) in patients with a high thrombus grade. CONCLUSION In STEMI patients, MT was associated with the occurrence and extent of MVO, on CMR, especially in patients with a high thrombus burden.

Abstract
OBJECTIVES We sought to characterize the hemodynamic impact of mild coronary artery disease (CAD) using quantitative flow ratio (QFR, an angiography-derived fractional flow reserve [FFR]) in a population of patients with only non-significant CAD at baseline that subsequently experienced a myocardial infarction (MI). BACKGROUND The discriminatory value of FFR in patients with mild CAD remains imperfect. METHODS We retrospectively included patients who underwent invasive coronary angiography for an MI, in whom another angiogram had been performed within the previous 5 years. Three-dimensional quantitative coronary angiography, QFR, and lesion length analysis were conducted on lesions responsible for the MI (future culprit lesions, [FCL]) as well as on control lesions (non-culprit lesions, [NCL]). RESULTS Eighty-three FCL and 117 NCL were analyzed in 83 patients: FCL were more severe (median % diameter of stenosis [DS] 39.1% [29.8; 45.7] vs. 29.8% [25.0; 37.2], p < .001), had lower QFR values (0.94 [0.86; 0.98] vs. 0.98 [0.96; 1.00], p < .001) and tended to be longer (15.2 mm [10.0; 27.3] vs. 12.7 mm [9.3; 22.4], p = .070) than NCL. In lesions with an interval < 2 years between baseline angiography and MI, the difference in QFR was more pronounced compared to the lesions with a longer interval (FCL: 0.92 [0.85; 0.97] vs. NCL: 0.98 [0.94; 1.00], p < .001 and FCL: 0.96 [0.88; 1.00] vs. NCL: 0.98 [0.96;1.00], p = .006 respectively) CONCLUSION: Mild coronary stenoses that are subsequently responsible for an MI (FCL) exhibit a higher DS and lower QFR years before the event. Furthermore, FCL with a lower QFR at baseline appear to lead earlier to MI.

Abstract
Purpose: We carried out this study to evaluate the predictive value of atherosclerosis burden score (ABS) to predict coronary artery disease (CAD) among asymptomatic patients without known cardiovascular disease (CVD), as compared to other imaging or functional techniques, namely coronary artery calcium (CAC) score, carotid intima-media thickness (C-IMT), and ankle brachial index (ABI). Patients and methods: This prospective study included 198 asymptomatic consecutive patients referred for evaluation of their cardiovascular (CV) risk and for therapeutic advice. Traditional CV risk factors, ABS, CAC score, C-IMT, ABI and an ECG-synchronized coronary CT-angiography (CCTA) were performed for each patient. We compared the predictive values of these atherosclerosis markers to detect CAD defined as coronary stenosis ≥30% objectivated by CCTA. Results: Among the whole sample, the area under the receiver-operating characteristic curve (ROC-AUC) was significantly higher for CAC score (0.81, p=0.015) than for ABS, the reference (0.70) but these values were lower for C-IMT (0.60, p=0.16) and particularly for ABI (0.56, p=0.0015). However, among patients at intermediate risk of coronary heart disease (CHD), according to Framingham risk score (FRS), the differences between the ROC-AUC values for ABS (0.70) and CAC score (0.76, p=0.36) were less pronounced. Again, as compared to ABS, the ROC-AUC values were lower for C-IMT (0.60, p=0.21) and ABI (0.57, p=0.06). Conclusions: ABS, an ultrasonographic score based on the assessment of carotid and femoral plaque burden, predicts more accurately CAD than other non-radiation tools analyzed here, and has a similar performance to CAC in patients at intermediate CHD risk. Thus, ABS could be an appropriate non-invasive and safe method to improve the detection of high-risk patients who will benefit from a more intensive therapy for the primary prevention of CVD.

Abstract
Background Computed tomography angiography (CTA) is used to plan TAVI procedures. We investigated the performance of pre-TAVI CTA for excluding coronary artery disease (CAD). Methods In total 127 patients were included. CTA images were analyzed for the presence of ≥ 50% (significant CAD) and ≥ 70% (severe CAD) diameter stenoses in proximal coronary arteries. Results were compared with invasive coronary angiography (ICA) at vessel and patient levels. Primary endpoint was the negative predictive value (NPV) of CTA for the presence of CAD. Results A total of 342 vessels were analyzable. NPV of CTA was 97.5% for significant CAD and 96.3% for severe CAD. Positive predictive value and accuracy were 44.8% and 87.1% for significant CAD and 56.3% and 94.4% for severe CAD. At patient level, NPV for significant CAD was 88.6%. Conclusion Pre-TAVI CTA shows good performance for ruling out CAD and could be used as a gatekeeper for ICA in selected patients. Graphical abstract ![]()

Abstract
In 2020, new guidelines have been published by the European Society of Cardiology including those on non-ST-segment elevation acute coronary syndromes, atrial fibrillation and adult congenital heart disease. Regarding interventional cardiology, POPular TAVI opens the possibility of anti-platelet monotherapy after transcutaneous aortic valve replacement. EMPEROR-Reduced confirms the importance of SGLT2 inhibitors in the treatment of heart failure with reduced ejection fraction. Within the field of imaging, stress MRI has now become the first-line technique for the screening of coronary artery disease, demonstrating an excellent cost-benefit ratio. Finally, renin-angiotensin-aldosterone inhibitors do not appear to increase the risk of an infection by COVID-19.

Abstract
OBJECTIVES The transfemoral (TF) approach is the gold-standard access route for transcatheter aortic valve replacement (TAVR). Alternative approaches, among which the transcervical (TC) approach, are needed in some patients. We aimed to compare TC-TAVR with TF-TAVR. METHODS All patients who underwent TAVR in our institution between 2016 and 2020, using Edwards SAPIEN family balloon-expandable transcatheter heart valves, were retrospectively included. Endpoints included 30-day all-cause mortality, procedural complications (according to the VARC-2 criteria), procedure duration, hospital length of stay (LOS) and echocardiographic outcomes. For 30-day all-cause mortality, we furthermore used a Cox proportional-hazards model to adjust for significant between-group differences in baseline characteristics as well as anesthesia modality. RESULTS TAVR was performed in 306 patients, using a TF approach (n = 255) or a TC approach (n = 51). TC-TAVR was associated with significantly higher STS scores (4.06 [IQR (interquartile range), 2.05, 5.56] vs. 2.97 [IQR, 2.08, 4.88], p < 0.001) and higher prevalence of peripheral artery disease, history of stroke, previous cardiovascular surgery. 30-day mortality (hazard ratio, 0.87 [0.77, 9.77], p = 0.909) and stroke rates (2.0% vs. 1.6%, p = 0.840) were similar, as well as procedural duration (74.0 [53.0, 99.5] vs. 77.0 [58.0, 98.0] minutes, p = 0.370), LOS (6.0 [IQR, 3.0, 8.0] vs. 6.0 [IQR, 4.0, 9.0] days, p = 0.175) and postprocedural mean transvalvular gradient (10.00 [IQR, 8.00, 13.00] vs. 10.00 [IQR, 8.00, 12.00] mmHg, p = 0.724). CONCLUSION Despite a higher cardiovascular disease burden in TC patients, TC-TAVR and TF-TAVR yielded similar outcomes. TC-TAVR may be a safe alternative when TF-TAVR is contraindicated.

Abstract
BACKGROUND The PAST-PERF registry was initiated to collect data on the PK Papyrus covered stent, a second-generation device for the treatment of coronary artery perforations with enhanced mechanical properties, but with limited available data. METHODS Patients treated for coronary artery perforations with the PK Papyrus stent at 14 international centers were retrospectively identified. The primary effectiveness outcome was successful sealing of the perforation. The primary safety outcome was a composite of all-cause mortality, definite or probable stent thrombosis, myocardial infarction and target lesion revascularization. RESULTS Among the 94 included patients, 72.3% (68/94) had Ellis type III and cavity spilling perforations. Complete sealing was achieved in 93.6% (n = 88), and no sealing could be achieved in 3.2% (n = 3, including one patient with a geographical miss and one patient in whom the device could not be implanted). Pericardiocentesis was required in 25.0% (n = 23), emergency cardiac surgery was needed in 7.6% (n = 7), acute stent thrombosis was observed in 1.1% (n = 1), and in-hospital mortality occurred in 11.7% (n = 11). The median follow-up duration was 283 (IQR:40;670) days. At 6 and 12 months, the incidence of the primary safety endpoint was 26.6% [95%CI:18.6;37.1] and 32.0% [95%CI:22.8;43.4], mortality 15.0% [95%CI:9.0;24.6] and 19.0% [95%CI:11.3;30.0], and target lesion revascularization 5.5% [95%CI:2.0;14.6] and 7.7% [95%CI:3.1;18.2]. Two definite stent thrombosis occurred, one during the procedure and one on post-procedure day 233. CONCLUSIONS The registry demonstrates favorably high rates of successful stent delivery and sealing of coronary perforations using a second-generation covered stent with low target lesion revascularization and stent thrombosis rates. ANNOTATED TABLE OF CONTENT The PAST-PERF registry demonstrates favorably high rates of successful stent delivery and sealing of coronary perforations using a second-generation covered stent with low target lesion revascularization and stent thrombosis rates. Specifically, complete sealing was achieved in 93.6% of patients (n = 88/94), and no sealing could be achieved in 3.2% (n = 3, including one patient with a geographical miss and one patient in whom the device could not be implanted). The 12-month mortality was 19.0% [95%CI:11.3;30.0], the rate of target lesion revascularization was 7.7% [95%CI:3.1;18.2], and two definite stent thromboses occurred (one during procedure and one on post-procedure day 233).

Abstract
Objectives T2*-weighted (T2*w) is deemed as a reference standard for post-infarction intramyocardial haemorrhage (IMH). However, high proportion of T2* images is affected by off-resonance artefacts hampering image interpretation. Diagnostic accuracy and precision of alternative techniques for IMH diagnosis and quantification have been seldomly investigated. Methods and results Between April 2016 and May 2017, 50 ST-segment elevation myocardial infarction patients (66% male, 57 ± 17 years) and 15 healthy controls (60% male, 58 ± 13) were consecutively enrolled. Subjects underwent head-to-head comparison of single mid-infarct slice acquired on black-blood T2-weighted short-TI-inversion recovery (T2w-STIR), bright-blood T2prep-steady-state-free precession (T2prep-SSFP), and T2/T1 maps for IMH diagnosis and quantification against T2*w. All images were graded for quality (grade 1: very poor; grade 4: excellent) and diagnostic confidence (Likert scale, 1: very unsure and 5: highly confident). Reduced relaxation time/hypointense region (hypocore) embedded in infarct-related oedema on T2 map, T1 map, and T2w-STIR had the best overall diagnostic accuracy (per-subject: 91%, 86%, and 86%, respectively; per segment: 95%, 93%, and 93%, respectively). By mixed-effects analysis, image quality, and diagnostic confidence were higher for T2 map and T1 maps than T2*w (p < 0.05 for both scores). For IMH quantification, hypocore on T2 map and T1 map strongly correlated (Spearman’s r > 0.7, p < 0.001 for both) with IMH extent on T2*w and presented an overall excellent agreement on Bland-Altman analysis. By linear mixed model analysis, absolute hypocore size did not differ among T1-, T2 map, and T2*w. T2/T1 maps had the best intra- and inter-observer reproducibility among CMR techniques. Conclusion Hypocore on T2/T1 map is the best alternative technique to T2*w for diagnosing and quantifying IMH in post-STEMI patients. Key Point • Mapping techniques are the best alternatives for diagnosing post-infarction intramyocardial haemorrhage. • Mapping techniques are valuable tools for imaging intramyocardial haemorrhage.

Abstract
Background In the era of High-sensitive troponin (hs-Tn), up to 50% of patients with a mild increase of hs-Tn will finally have a normal invasive coronary angiogram. Fractional Flow Reserve (FFR) derived from coronary computed tomographic angiography (FFR-CT) has never been used as a non-invasive tool for the diagnosis of coronary artery disease in patients with high-risk acute coronary syndrome without ST segment elevation (NSTE-ACS). Aims The study aims to determine the role of coronary CT angiography and FFR-CT in the setting of high-risk NSTE-ACS. Methodology We will conduct a prospective trial, enrolling 250 patients admitted with high-risk NSTE-ACS who will rapidly undergo a coronary CT angiography and then a coronary angiography with FFR measurements. Results of coronary CT, FFR-CT and coronary angiography (± FFR) will be compared. Potential significance In conclusion, non-invasive identification of patients with high-risk NSTE-ACS who could avoid coronary angiography would reduce procedure related risks and medical costs.

Abstract
BACKGROUND Interatrial septum (IAS) dissection due to transseptal puncture (TSP) is a rare, underreported complication of the procedure. Data on the mechanism, diagnosis, and management of this complication are lacking. METHODS We conducted a systematic review of all reported cases of IAS dissection with or without associated LA hematoma due to TSP, by thoroughly searching MEDLINE and EMBASE through May 2019. RESULTS After screening of n = 882 studies, eight studies with a total of 19 patients addressed the complication of IAS dissection and/or LA hematoma secondary to TSP. Median age was 63 years with a 1:1 male to female ratio. Ablation of atrial fibrillation was the most frequently reported procedure (84%). Diagnosis was established using fluoroscopy with contrast injection (58%), TEE (32%) or intracardiac echocardiography (5%). The mechanism identified involved puncture of the septum secundum portion of the IAS, leading to transient needle passage into the extracardiac space. In the majority of patients, the hematoma remained localized in the IAS and management was conservative with progressive resolution of the hematoma during follow-up (95%). Two patients (11%) required further intervention by either pericardiocentesis or surgical drainage due to hemodynamic instability. CONCLUSIONS IAS dissection with or without hematoma after TSP remains an underdiagnosed entity. The main mechanism involves lesion to the septum secundum portion of the IAS, resulting in needle passage into the extracardiac space and local bleeding. Although conservative management may be sufficient in the majority of cases, interventional cardiologists should be familiar with this complication and its diagnosis.

Abstract
Early initiation of reperfusion therapy remains the cornerstone of successful management for ST-elevation myocardial infarction (STEMI). Rapid restoration of coronary blood flow relies on prompt recognition of the typical ST-segment elevation on a 12-lead electrocardiogram (ECG)-a surrogate for coronary occlusion or critical stenosis-allowing timely activation of the STEMI protocol cascade, with a major positive impact in mortality and clinical outcomes. However, atypical, very high risk ECG patterns-known as "STEMI equivalents"-are present in 10% to 25% of patients with ongoing myocardial ischemia in need of urgent primary percutaneous coronary intervention. Though briefly mentioned in the current recommendations, structured clinical data on those specific ECG presentations are lacking. By thoroughly searching MEDLINE and EMBASE we conducted a structured review of non-STEMI, albeit very high risk, ECG patterns of acute coronary syndrome, often associated with coronary occlusion or critical stenosis. After screening 997 studies, we identified the following distinct "STEMI equivalent" ECG patterns: Wellens' syndrome, de Winter sign, hyperacute T waves, left bundle branch block-including paced rhythm-and right bundle branch block. For each pattern, a brief summary of the existing evidence, together with the sensitivity, specificity, and positive predictive value-whenever available-are presented. In conclusion, prompt recognition of "STEMI equivalent" ECG patterns is crucial for every physician or paramedic dealing with acute coronary syndrome patients in the emergency department or the prehospital setting, as misinterpretation of those high risk presentations can lead to reperfusion delays and worse outcomes.

Abstract
BACKGROUND Newer-generation drug-eluting stents that combine ultrathin strut metallic platforms with biodegradable polymers might facilitate vascular healing and improve clinical outcomes in patients with acute myocardial infarction undergoing primary percutaneous coronary intervention (PCI) compared with contemporary thin strut second-generation drug-eluting stents. We did a randomised clinical trial to investigate the safety and efficacy of ultrathin strut biodegradable polymer sirolimus-eluting stents versus thin strut durable polymer everolimus-eluting stents in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI. METHODS The BIOSTEMI trial was an investigator-initiated, multicentre, prospective, single-blind, randomised superiority trial at ten hospitals in Switzerland. Patients aged 18 years or older with acute STEMI who were referred for primary PCI were eligible to participate. Patients were randomly allocated (1:1) to either biodegradable polymer sirolimus-eluting stents or durable polymer everolimus-eluting stents. Central randomisation was done based on a computer-generated allocation sequence with variable block sizes of 2, 4, and 6, which was stratified by centre, diabetes status, and presence or absence of multivessel coronary artery disease, and concealed using a secure web-based system. Patients and treating physicians were aware of group allocations, whereas outcome assessors were masked to the allocated stent. The experimental stent (Orsiro; Biotronik; Bülach, Switzerland) consisted of an ultrathin strut cobalt-chromium metallic stent platform releasing sirolimus from a biodegradable polymer. The control stent (Xience Xpedition/Alpine; Abbott Vascular, Abbott Park, IL, USA) consisted of a thin strut cobalt-chromium stent platform that releases everolimus from a durable polymer. The primary endpoint was target lesion failure, a composite of cardiac death, target vessel myocardial reinfarction (Q-wave and non-Q-wave), and clinically-indicated target lesion revascularisation, within 12 months of the index procedure. All analyses were done with the individual participant as the unit of analysis and according to the intention-to-treat principle. The trial was registered with ClinicalTrials.gov, number NCT02579031. FINDINGS Between April 26, 2016, and March 9, 2018, we randomly assigned 1300 patients (1623 lesions) with acute myocardial infarction to treatment with biodegradable polymer sirolimus-eluting stents (649 patients and 816 lesions) or durable polymer everolimus-eluting stents (651 patients and 806 lesions). At 12 months, follow-up data were available for 614 (95%) patients treated with biodegradable polymer sirolimus-eluting stents and 626 (96%) patients treated with durable polymer everolimus-eluting stents. The primary composite endpoint of target lesion failure occurred in 25 (4%) of 649 patients treated with biodegradable polymer sirolimus-eluting stents and 36 (6%) of 651 patients treated with durable polymer everolimus-eluting stents (difference -1·6 percentage points; rate ratio 0·59, 95% Bayesian credibility interval 0·37-0·94; posterior probability of superiority 0·986). Cardiac death, target vessel myocardial reinfarction, clinically-indicated target lesion revascularisation, and definite stent thrombosis were similar between the two treatment groups in the 12 months of follow-up. INTERPRETATION In patients with acute STEMI undergoing primary PCI, biodegradable polymer sirolimus-eluting stents were superior to durable polymer everolimus-eluting stents with respect to target lesion failure at 1 year. This difference was driven by reduced ischaemia-driven target lesion revascularisation in patients treated with biodegradable polymer sirolimus-eluting stents compared with durable polymer everolimus-eluting stents.

Abstract
Abstract
Background
Manual thrombectomy (MT) in ST segment elevation myocardial infarction (STEMI) is not associated with improved outcome and may even be harmful. Microvascular obstruction (MVO) assessed with cardiac magnetic resonance (CMR) imaging is among the strongest outcome predictors after STEMI.
Purpose
We aimed to investigate the impact of MT on MVO occurrence and extent.
Method
Between December 2010 and June 2017, 401 consecutive STEMI patients admitted for primary PCI, and still hospitalized in our tertiary care hospital at day 3 or later, (i.e. not transferred to another hospital) underwent a CMR during the index hospitalization (routine care at our institution during this period). Among them, 383 patients fulfilled the inclusion criteria and were classified into 2 categories (with or without MT) while 18 patients were excluded because of incomplete CMR data. The 2 co-primary endpoints were the occurrence and the extent of MVO, with these latter being analyzed either as a categorical variable (MVO vs. No-MVO) or as a semi-continuous variable (numbers of segments with MVO), respectively.
Results
In total, 188 (49.1%) patients experienced MVO. Both the incidence of MVO and the median number of segments with MVO were significantly higher in the MT group as compared to the no-MT group (59.5% vs 38.9%, respectively p<0.001, Figure 1A) and (0 [0; 2] vs 1.5 [0; 4]; respectively, p<0.001). When stratifying the analysis on coronary thrombus grade (Figures 1B and 1C), similar results were found only in patients with high thrombus burden (43.5% vs 60.7%, respectively, p=0.004). When adjusting for baseline differences between the 2 groups, MT remained a determinant of MVO (OR 1.90 (CI 95% 1.08 to 3.34); p=0.026) in patients with high thrombus grade.
Figure 1
Conclusion
In STEMI patients undergoing primary PCI, MT is associated with the occurrence and the extent of MVO assessed by CMR, especially in patients with a high thrombus grade. This suggests thrombus fragmentation with distal embolization as a potential mechanistic explanation.

Abstract
BACKGROUND Clavicular fracture or sternoclavicular luxation is observed in 10% of all polytrauma patients and is frequently associated with concomitant intrathoracic life-threatening injuries. Posterior sternoclavicular luxation is well known to induce underlying great vessels damage. The gold standard treatment usually is a combined orthopedic and cardiovascular surgical procedure associating vascular repair, clavicular open reduction, and internal fixation. METHODS A 59-year-old wheelchair ridden, institutionalized woman, known for psychiatric disorder, severe scoliosis, malnutrition, and chronic obstructive pulmonary disease was admitted in our hospital for chronic chest pain 3 months after a stairway wheelchair downfall. A thoracic computed tomography (CT) scan revealed a voluminous ascending aortic pseudoaneurysm (63 × 58 mm, orifice 5 mm) consecutive to perforation following posterior sternoclavicular luxation. The patient refused all therapies and was lost to follow-up. Six months later, she was readmitted for a symptomatic superior vena cava syndrome. Thoracic CT scan revealed pseudoaneurysm growth with innominate vein thrombosis and superior vena cava subocclusion. Pseudoaneurysm orifice was stable. In the presence of symptoms with massive facial edema and inability to open her eyelids, the patient accepted an endovascular treatment. RESULTS The procedure was performed under general anesthesia using both fluoroscopic and transesophageal echocardiographic guidance. Through a femoral arterial access, a 10-mm atrial septal defect occluder device was used to seal successfully the pseudoaneurysm orifice. The superior vena cava was then opened with a 26-mm nitinol high radial force stent through a femoral venous access. Postoperative course was uneventful. At 3-month follow-up, the patient remains symptom free and a CT scan confirmed pseudoaneurysm thrombosis and superior vena cava permeability. CONCLUSION Post-traumatic sternoclavicular posterior luxation is a cause of great vessels and ascending aorta injuries. Minimally invasive endovascular approaches can be considered to treat vascular injuries and their consequences, especially in elderly patients and those at high risk for surgery.

Abstract
INTRODUCTION AND OBJECTIVE The edge vascular response (EVR) remains unknown in second generation drug-eluting Resorbable Magnesium Scaffold (RMS), such as Magmaris. The aim of the study was to evaluate tissue modifications in the RMS edges over time, assessed by different invasive imaging modalities. METHODS The patients treated with the device were assessed by optical coherence tomography (OCT), grayscale intravascular ultrasound (IVUS), and virtual histology IVUS at baseline and 12 months. The EVR study performed a segment- and frame-level analysis of the 5 mm segments proximal and distal of the actual RMS. RESULTS The segment-level grayscale IVUS (n = 10), virtual histology IVUS (n = 10), and OCT (n = 18) analysis did not show any significant changes after 12 months, except for a fibrous plaque area (FPA) reduction of 0.5mm2 (p = 0.017) in the proximal segment compared to baseline. In the frame-level analysis, IVUS evaluation revealed a vessel area decreased 2.80 ± 1.43 mm2 (p = 0.012) and 2.49 ± 1.53 mm2 (p = 0.022) in 2 proximal frames. This was accompanied by plaque area reduction of 0.88 ± 0.70 mm2 (p = 0.048) and a FPA decreased by 0.63 ± 0.48 mm2 (p = 0.004) in one proximal frame. In 1 distal frame, there was a dense calcium area reduction of 0.10 ± 0.12 mm2 (p = 0.045), FPA and fibrous fatty plaque increased 0.54 ± 0.53 mm2 (p = 0.023) and 0.17 ± 0.16 mm2 (p = 0.016), respectively. By OCT, there was a lumen area decrease of 0.76 ± 1.51 mm2 (p = 0.045) in a distal frame. CONCLUSION At 12 months, Magmaris EVR assessment does not show overall significant changes, except for a fibrous plaque area reduction in the proximal segment. This could be translated as a benign healing process at the edges of the RMS. SUMMARY The edge vascular response (EVR) remains unknown in second generation drug-eluting absorbable metal scaffolds (RMS), such as Magmaris. Patients treated with the device were assessed by multi invasive imaging modalities [i.e. optical coherence tomography (OCT), grayscale intravascular ultrasound (IVUS), and virtual histology IVUS] evaluating the tissue changes over time in the segment- and frame-level analysis of the 5 mm segments proximal and distal of the actual RMS. As a result, after 12 months, Magmaris EVR assessment does not show overall significant changes, except for a fibrous plaque area reduction in the proximal segment, translating a benign healing process at the edges of the RMS.
