Background. The revascularization of small vessels using drug-eluting stents remains challenging. The use of the drug-coated balloon is an attractive therapeutic strategy in de novo lesions in small coronary vessels, particularly in the diabetic group. This study aimed to assess the outcomes of DCB-only angioplasty in small vessel disease. Methods. A total of 1198 patients with small vessel disease treated with DCB-only strategy were followed. Patients were divided into the diabetic and nondiabetic groups. Clinical and angiographical follow-up were organized at 12 months. The primary endpoints were target lesion failure and secondary major adverse cardiac events. Results. There was a significantly higher rate of target lesion failure among diabetic patients compared to nondiabetic [17 (3.9%) vs. 11 (1.4%), P = 0.006 ], taken separately, the rate of target lesion revascularization significantly differed between groups with a higher rate observed in the diabetic group [9 (2%) vs. 4 (0.5%), P = 0.014 ]. Diabetes mellitus remained an independent predictor for TLF (HR: 2.712, CI: 1.254–5.864, P = 0.011 ) and target lesion revascularization (HR: 3.698, CI: 1.112–12.298, P = 0.033 ) after adjustment. However, no significant differences were observed between groups regarding the target vessel myocardial infarction (0.6% vs. 0.1%, P = 0.110 ) and MACE [19 (4.4%) vs. 21 (2.7%), P = 0.120 ]. Conclusion. Drug-coated balloon-only treatment achieved lower incidence rates of TLF and MACE. Diabetes is an independent predictor for target lesion failure and target lesion revascularization at one year following DCB treatment in small coronary vessels. We observed no significant differences between groups regarding MACE in one year.

Objective To evaluate the 1-year clinical outcomes of patients who received the Resolute Onyx™ stent. Methods This was a single-centre, retrospective registry analysis that reviewed the clinical data from all patients who were implanted with a Resolute Onyx™ stent between March 2015 and February 2016. Clinical follow-up was performed at 1 year post-implantation. Results A total of 252 patients received a Resolute Onyx™ stent and two patients were lost to follow-up. The mean age of the cohort was 66.9 years and 113 (45.2%) had diabetes mellitus. Thirty-eight patients (15.2%) had left main disease and 73 (29.2%) had three-vessel disease. A total of 175 patients (70.0%) had small vessel disease (<2.75 mm) and 210 (84.0%) had long lesions (>20 mm). The 1-year target lesion failure was 4.4% (11 of 250), cardiovascular death occurred in eight patients (3.2%), ischaemia-driven target lesion revascularization was undertaken in five patients (2.0%) and stent thrombosis occurred in one patient (0.4%). Conclusion The Resolute Onyx™ stent showed a favourable 1-year clinical performance in a real-world population.

Στην παρούσα διατριβή συγκρίθηκαν σε 600 ασθενείς οι μακροπρόθεσμες εκβάσεις χρόνιας σταθερής στηθάγχης και μονήρους de-novo βλάβης στο εγγύς τμήμα του προσθίου κατιόντα που υποβλήθηκαν σε διαδερμική στεφανιαία παρέμβαση με επικαλυμμένα stents εκλυτικής ουσίας zotarolimus (E-ZES) (Ν=180) με εκείνες ασθενών ιδίου προβλήματος και αντιμετώπισης με εκλυτική ουσία everolimus (EES) (Ν=420), με μέση κλινική παρακολούθηση τους 54,9 + 25,6 μήνες. Το πρωταρχικό τελικό σημείο της μελέτης ήταν η «αποτυχία» της βλάβης στόχου (Target Lesion Failure- TLF), ένας σύνθετος δείκτης, που καθορίζεται με ιεραρχική σειρά από: καρδιακό θάνατο, μη θανατηφόρο έμφραγμα του μυοκαρδίου που δεν αποδίδεται σαφώς σε αγγείο άλλο από το αγγείο στόχο και την κλινικά κατευθυνόμενη επαναγγείωση της βλάβης στόχου (Target Lesion Revascularization-TLR). Τα δευτερεύοντα καταληκτικά σημεία ήταν εκβάσεις σχετιζόμενες με τον ασθενή (PRO-σύνθετος δείκτης που απαρτίζουν η ολική θνησιμότητα, το έμφραγμα του μυοκαρδίου σε οποιοσδήποτε αγγείο, η επαναγγείωση σε οποιοδήποτε αγγείο), η θρόμβωση του stent και τα επιμέρους συστατικά του TLF (καρδιακός θάνατος, μη θανατηφόρο έμφραγμα του μυοκαρδίου και TLR). Η χρήση των EES σε μονήρεις de-novo βλάβες του LAD, οδήγησε σε στατιστικά σημαντική μείωση των κλινικών συμβαμάτων σε σύγκριση με τα E-ZES. Στα 5 χρόνια κλινικής παρακολούθησης, παρατηρήθηκαν στατιστικά σημαντικές διαφορές στη σωρευτική πιθανότητα εμφάνισης συμβαμάτων στην ομάδα ασθενών που έλαβαν E-ZES έναντι της ομάδας των ασθενών που έλαβαν EES μόνον αναφορικά με TLF (13,8% στην ομάδα E-ZES έναντι 7,5% στην ομάδα EES, p=0,025) και TLR (10% στην ομάδα E-ZES έναντι 3,3% στην ομάδα EES, p=0,003). Για όλες τις άλλες εκβάσεις δεν παρατηρήθηκαν διαφορές. Οι διαφορές μεταξύ των ενδοπροθέσεων ως προς το πρωτογενές καταληκτικό σημείο αυξήθηκαν μετά από 30 μήνες. Οι προγνωστικοί δείκτες του προτυπωμένου για τον τύπο του stent TLF ήταν ο σακχαρώδης διαβήτης και ο επηρεασμένος εκτιμώμενος ρυθμός σπειραματικής διήθησης (eGFR). Επιπλέον σε 631 ασθενείς με PCI-DES και 379 ασθενείς με CABG συγκρίθηκαν τα μακροπρόθεσμα αποτελέσματα της διαδερμικής στεφανιαίας παρέμβασης με δεύτερης γενιάς επικαλυμμένες ενδοπροθέσεις και της επέμβασης αορτοστεφανιαίας παράκαμψης με χρήση της αριστερής έσω μαστικής αρτηρίας σε ασθενείς με σταθερή στηθάγχη με μονήρη βλάβη στο εγγύς τμήμα του προσθίου κατιόντα. Το κύριο καταληκτικό σημείο της δεύτερης μελέτης ήταν η εμφάνιση σύνθετου δείκτη MACEs (καρδιακός θάνατος, έμφραγμα μυοκαρδίου που δεν αποδίδεται σαφώς σε αγγείο άλλο από το αγγείο στόχο και επαναγγείωση της βλάβης στόχου με χρήση διαδερμικής ή χειρουργικής τεχνικής. Δευτερεύοντα τελικά σημεία ήταν εκβάσεις σχετιζόμενες με τον ασθενή (PRO), καθώς και επιμέρους εκβάσεις των MACEs, επανεμφάνιση σταθερής ή ασταθούς στηθάγχης ή εμφάνιση μη θανατηφόρου αρρυθμίας, διάρκεια νοσηλείας, οποιαδήποτε επιπλοκή (περιεπεμβατική ή ενδονοσοκομειακή) και εξέλιξη της νόσου σε άλλα τμήματα (έμφραγμα μυοκαρδίου σε αγγείο άλλο από το αγγείο στόχο, νέα εμφάνιση σταθερής στηθάγχης που αποδίδεται σε αγγείο ή σε τμήμα αγγείου άλλο από το υπό μελέτη και που προσδιορίζεται με δοκιμασία ισχαιμίας-καρδιακό σπινθηρογράφημα ή/και αγγειογραφία). Υπολογίστηκαν οι μη προτυπωμένες και στη συνέχεια προτυπωμένες αναλογίες κινδύνου (HR) για τα υπό εξέταση κύρια συμβάματα. Το κύριο εύρημα ήταν ότι τα μακροπρόθεσμα ποσοστά MACE ήταν συγκρίσιμα μεταξύ των δύο ομάδων, παρά τον οριακά στατιστικά σημαντικό μικρότερο κίνδυνο της επαναγγείωσης στην ομάδα CABG από ό,τι στην ομάδα PCI. Συγκεκριμένα, δεν παρατηρήθηκε σημαντική διαφορά μεταξύ των δύο ομάδων κατά τη διάρκεια της κλινικής παρακολούθησης σχετικά με τα MACEs, το PRO, τον καρδιακό θάνατο και το έμφραγμα του μυοκαρδίου. Σε σύγκριση με το CABG, η PCI με δεύτερης γενιάς DES παρουσίασε σημαντικά μεγαλύτερο κίνδυνο επαναγγείωσης (HR PCI:1,99, 95% CI:1,00-3,94, p=0,05 και HR PCI:1,95, 95% CI:0,98-3,9, p=0,06). Ο κίνδυνος για την επανεμφάνιση σταθερής στηθάγχης ήταν σημαντικά αυξημένος στην ομάδα PCI σε σύγκριση με την ομάδα CABG (p <0,001), αλλά ο κίνδυνος εμφάνισης μη θανατηφόρας αρρυθμίας (κολπική μαρμαρυγή, κολπικός πτερυγισμός ή μη εμμένουσα κοιλιακή ταχυκαρδία) ήταν μεγαλύτερος στην ομάδα χειρουργικής επέμβασης από ό,τι στην ομάδα PCI (p=0,02). Η χειρουργική προσέγγιση συσχετίστηκε με υψηλότερα ποσοστά ενδονοσοκομειακών επιπλοκών (p <0,001) και μεγαλύτερης διάρκειας νοσηλεία (p <0,001) σε σύγκριση με εκείνα στην ομάδα PCI. Συμπερασματικά, και οι δύο τύποι stents, EES και E-ZES, επέδειξαν ένα ευνοϊκό προφίλ ασφαλείας. Η χρήση των EES φάνηκε στη μελέτη μας να έχει ελαφρώς καλύτερη αποτελεσματικότητα σε ορισμένους δείκτες (TLF, TLR). Οι μακροπρόθεσμες κλινικές εκβάσεις της δεύτερης γενιάς PCI-DES και του CABG σε ασθενείς με σταθερή στηθάγχη και μονήρη βλάβη στον pLAD ήταν συγκρίσιμες, υπογραμμίζοντας τα εξαιρετικά μακροπρόθεσμα αποτελέσματα τόσο της χειρουργικής όσο και της DES-PCI προσεγγίσεως. Τα παρόμοια ποσοστά καρδιακής θνησιμότητας και ο παραπλήσιος κίνδυνος του εμφράγματος του μυοκαρδίου μπορούν ελαφρώς να αντισταθμιστούν από τον αυξημένο κίνδυνο επανεπέμβασης στην ομάδα ασθενών που υποβλήθησαν σε PCI στον pLAD με δεύτερης γενιάς DES, αν και τα συνολικά MACEs ήταν παρόμοια.

Objectives. We analyzed the efficacy of drug coated balloons (DCB) as a stand-alone-therapy in de novo lesions of large coronary arteries. DCBs seem to be an attractive alternative for the stent-free interventional treatment of de novo coronary artery disease (CAD). However, data regarding a DCB-only approach in de novo CAD are currently limited to vessels of small caliber. Methods. By means of propensity score (PS) matching 234 individuals with de novo CAD were identified with similar demographic characteristics. This patient population was stratified in a 1:1 fashion according to a reference vessel diameter cut-off of 2.75 mm in small and large vessel disease. The primary endpoint was the rate of clinically driven target lesion revascularization (TLR) at 9 months. Results. Patients with small vessel disease had an average reference diameter of 2.45 ± 0.23 mm, while the large vessel group averaged 3.16 ± 0.27 mm. Regarding 9-month major adverse cardiac event (MACE), 5.7% of the patients with small and 6.1% of the patients with large vessels had MACE (p=0.903). Analysis of the individual MACE components revealed a TLR rate of 3.8% in small and 1.0% in large vessels (p=0.200). Of note, no thrombotic events in the DCB treated coronary segments occurred in either group during the 9-month follow-up. Conclusions. Our data demonstrate for the first time that DCB-only PCI of de novo lesions in large coronary arteries (>2.75 mm) is safe and as effective. Interventional treatment for CAD without permanent or temporary scaffolding, demonstrated a similar efficacy for large and small vessels.

We evaluated the angiographic parameter and clinical outcomes of drug-coated balloon (DCB) to assess the optimal angiographic criteria in de novo small vessel disease (SVD). Patients (n = 424, mean age: 64.4 ± 11.2 years, men: 69.8%) at 20 sites in Korea were prospectively enrolled. The primary end point was late luminal loss (LLL) at 9-month follow-up angiography. Secondary end points included restenosis rates, target lesion failure (TLF), and DCB-related thrombosis during the 12-month follow-up period. We included 403 patients for analysis excluding 21 patients who required bailout stenting. Baseline mean reference vessel .diameter was 2.52 ± 0.39 mm and mean minimal luminal diameter (MLD) was 0.71 ± 0.40 mm. The mean MLD was 1.54 ± 0.37 mm after DCB. Late luminal loss was −0.01 ± 0.43 mm and restenosis was noted in 26 patients (12.2%). Minimal luminal diameter >1.6 mm and % diameter stenosis (DS ) <45% after DCB was associated maintenance of MLD without LLL at 9-months. Multivariate analysis demonstrated that %DS at baseline and post-MLD was associated with the restenosis. During 12-month follow-up, TLF was 2.6% including 1 cardiac death, 1 myocardial infarction, and 10 ischemia-driven target lesion revascularizations. Drug-coated balloon showed a low restenosis and lower LLL despite high in-segment DS. Post-MLD and % DS may be helpful to get optimal results in de novo SVD after DCB.

Abstract Background Chronic kidney disease (CKD) is highly prevalent in patients with coronary artery disease (CAD). Objective The outcome following revascularization using contemporary technologies (new-generation abluminal sirolimus-eluting stents with thin struts) in patients with CKD (i.e., glomerular filtration rate of < 60 mL/min/1.73m2) and in patients with hemodialysis (HD) is unknown. Methods e-Ultimaster is a prospective, single-arm, multi-center registry with clinical follow-up at 3 months and 1 year. Results A total of 19,475 patients were enrolled, including 1466 patients with CKD, with 167 undergoing HD. Patients with CKD had a higher prevalence of overall comorbidities, multiple/small vessel disease (≤ 2.75 mm), bifurcation lesions, and more often left main artery treatments (all p < 0.0001) when compared with patients with normal renal function (reference). CKD patients had a higher risk of target lesion failure (unadjusted OR, 2.51 [95% CI 2.04–3.08]), target vessel failure (OR, 2.44 [95% CI 2.01–2.96]), patient-oriented composite end point (OR, 2.19 [95% CI 1.87–2.56]), and major adverse cardiovascular events (OR, 2.34 [95% CI 1.93–2.83, p for all < 0.0001]) as reference. The rates of target lesion revascularization (OR, 1.17 [95% CI 0.79–1.73], p = 0.44) were not different. Bleeding complications were more frequently observed in CKD than in the reference (all p < 0.0001). Conclusion In this worldwide registry, CKD patients presented with more comorbidities and more complex lesions when compared with the reference population. They experienced higher rate of adverse events at 1-year follow-up. Graphic abstract

Abstract Background The optimal intervention strategy remains controversial in small vessel disease which is a very common kind of coronary artery lesions. For now, balloon-only percutaneous coronary intervention is the major percutaneous revascularization method in these patients, but the restenosis rate is still at a high level. Drug coated balloon is designed to deliver paclitaxel to target vessel to inhibit the proliferation of vascular endothelial cells, it aims at restraining the stenosis process after intervention so as to reduce the rate of restenosis. Ultrasound controlled paclitaxel releasing balloon catheter (Vasoguard TM ) is a newly designed drug coated balloon, expected to promote the drug release process via external ultrasound intervention so as to improve drug bioavailability. The current trial was designed to assess the efficacy and safety of Vasoguard in the treatment of small vessel coronary disease.Methods A prospective, multicenter, randomized, controlled clinical trial has been designed to compare the safety and efficacy of Vasoguard with plain balloon angioplasty in the treatment of small vessel coronary disease. 230 patients will be included in this trial, the primary endpoint is late lumen loss of target lesion at 9 months post operation measured by quantitative coronary angiography. Secondary endpoints include angiographic findings such as device success rate, operation success rate, in-segment restenosis, clinical outcomes such as target lesion revascularization, target vessel revascularization, device oriented composite endpoint and thrombotic events.Discussion This trial will evaluate the efficacy and safety of Vasoguard in the treatment of small vessel coronary disease by comparing to plain balloon angioplasty. It will clarify the practicability of the newly designed balloon and may lend more credence to the role of drug coated balloon in the treatment of small vessel disease.

Newer-generation drug-eluting stents (DES) are the standard of care for the treatment of symptomatic coronary artery disease. However, some lack of efficacy has been reported in small coronary arteries based on higher rates of target lesion restenosis, thrombosis and MI resulting in repeated interventions. Drug-coated balloons (DCBs) are an established treatment option for in-stent restenosis in both bare metal stents and DES and they can deliver an anti-proliferative drug into the vessel wall without implanting a stent. DCBs are a promising technique for selected de novo coronary lesions, especially in small vessel disease. In this article, the current evidence for the treatment of small vessel disease with DCBs will be reviewed.

Abstract Background Drug-coated balloon has been widely used to treat In-Stent Restenosis as recommended by ESC/EACT coronary intervention guideline. However, trials of effectiveness of DCB in treating de novo lesions in diabetic patients are limited. This study will highlight the impact of DCB in diabetic patients with only de novo lesions against non-diabetic patients. Aim To compare the outcomes of Paclitaxel Drug Coated Balloon (DCB) in Diabetic and non-diabetic patients with only de novo coronary artery disease. Methods A retrospective, single center study was conducted from January 2016 till December 2018. All diabetic and non-diabetic patients underwent angioplasty to only de novo coronary artery lesions were included in the study. Patients' baseline characteristic, angiographic data, post procedural and 12 months follow-up outcomes including major adverse coronary artery event (MACE), target lesion revascularization (TLR) and myocardial infarction (MI) are compared. Results A total of 1257 patients (726 diabetic and 531 non-diabetic patients) with total 1385 de novo coronary artery lesions (791 lesions in diabetic group and 594 lesions in non-diabetic group) were included in this study. Mean age for non-diabetic group was 57.6±10.6 years and diabetic group was 59.6±9.6 years with male predominance (91.1% in non-diabetic group, n=484 and 79.2% in diabetic group, n=575). Majority of diabetic group has hypertension (83.7%, n=608 vs 58.6%, n+311), chronic renal failure (10.3%, n=75 vs 1.9%, n=10), documented coronary artery disease (55.6%, n=404 vs 47.5%, n=252) and previous coronary angioplasty 39.5%, n=287 vs 28.8%, n=153). Adequate pre-dilatation was done in both groups (98.5%, n=585 in non-diabetic group and 99.4%, n=786 in diabetic group; p=0.000). Mean DCB diameter and length were almost similar in both groups. Mean residual stenosis after DCB was 11.15±16.9% in non-diabetic group and 13.13±13.4% in the diabetic group (p=0.008). 74.6% of non-diabetic group (n=396) and 77.1% of diabetic group (n=560) were on double antiplatelet therapy for 12 months. 86.8% (n=461) of non-diabetic and 88.4% (n=642) of diabetic patients were available for follow up. MACE events were significantly higher (p=0.000) in diabetic group (4.3%, n=31) as compare to non-diabetic group (0.6%, n=3). Target lesion revascularization (TLR) and myocardial infarction (MI) was also significantly higher in diabetic group (TLR 1.4%, N=10 vs 0.6%, n=3, p=0.049; MI 2.6%, n=19 vs 0.4%, n=2, p=0.002). Conclusion Treating de novo coronary lesions in diabetic patients with DCB associated with significantly higher MACE events, target lesion revascularization and myocardial infarction. Diabetic patients appear to have a greater volume of atherosclerotic plaque and increased propensity for atherosclerotic plaque rupture. Funding Acknowledgement Type of funding source: None
