Abstract Objective This study was aimed to compare different stenting techniques for coronary bifurcation disease (CBD). Background Percutaneous coronary intervention (PCI) remains controversial for CBD; over the years, several stent techniques for bifurcation lesions have been used. Current guidelines recommend a provisional single-stent strategy as the preferred method for coronary artery bifurcation lesions. However, several randomized controlled trials (RCT) indicated that two-stent techniques showed better clinical outcomes. Methods We systematically searched Embase, PubMed, and Web of Science to include RCTs. The primary endpoint was the major adverse cardiovascular event (MACE). Secondary outcomes were cardiac death, myocardial infarction (MI), target-lesion or target-vessel revascularization (TLR or TVR), and definite or probable stent thrombosis (ST). Finally, we used 26 RCTs and a total of 7257 individuals were randomly assigned to one of the 6 stent techniques and included in this network meta-analysis. Results In our network meta-analysis, double-kissing (DK) crush was significantly more superior to other 5 stent techniques in MACEs: OR vs. provisional 0.40 (95% CI 0.28–0.55); vs. culotte 0.40 (95% CI 0.26–0.60). DK crush ranked the most effective treatment for MACE (100%), MI (75%), ST (83%), and TLR (100%) in the rank probabilities analysis. In patients with complex bifurcation lesion defined by DEFINITION criteria, DK crush was notably more efficacious than provisional, culotte, and T-stenting/T-stenting and protrusion (TAP) in MACEs (OR vs. provisional 0.26, 95% CI 0.13–0.52) and TLR (OR vs. provisional 0.24, 95% CI 0.10–0.58). Conclusion Compared with other stenting techniques, DK crush had a lower incidence of MACEs in CBD. DK crush was significantly associated with a lower rate of MACEs in patients with complex bifurcation lesions defined by the DEFINITION criterion. Graphical abstract

Provisional T-stenting with stenting of the main branch and optional side branch (SB) stenting in the case of significant SB occlusion with thrombolysis in myocardial infarction (TIMI) flow <3 is the strategy chosen nowadays by most interventionalists for treating simple bifurcation lesions. Percutaneous coronary intervention (PCI) of complex true bifurcation lesions remains, however, the subject of debate: treatment of complex bifurcation lesions requires more time than treatment of simple bifurcations and can lead to significantly higher rates of restenosis, target lesion revascularisation and myocardial infarction. Current bifurcation techniques often fail to ensure continuous stent coverage of the SB ostium and of the two bifurcation branches without a simultaneous increase in the rate of malapposed struts. Stent struts left unapposed in the lumen disturb blood flow and are increasingly recognised as increasing the risk of stent thrombosis and focal in-stent restenosis, limiting the success of stent procedures in these lesions. New technology and dedicated designs may, in the near future, overcome such limitations of conventional two-stent bifurcation strategies.

Background. Individual randomized trials have suggested that everolimus-eluting stents may have improved clinical outcomes compared to paclitaxel-eluting stents, but individual trials are underpowered to examine outcomes such as mortality and very late stent thrombosis. Methods. Medline, Cochrane, and conference proceedings were searched for randomized trials comparing everolimus versus paclitaxel-eluting stents for percutaneous coronary intervention. Results. 6792 patients were included from 4 randomized controlled trials. Stent thrombosis was reduced with everolimus stents versus paclitaxel stents (0.7% versus 2.3%; OR: 0.32; CI: 0.20–0.51; P<0.00001). The reductions in stent thrombosis were observed in (i) early stent thrombosis (within 30 days) (0.2% versus 0.9%; OR: 0.24; P=0.0005), (ii) late (day 31–365) (0.2% versus 0.6%; OR: 0.32; P=0.01), and (iii) very late stent thrombosis (>365 days) (0.2% versus 0.8%; OR: 0.34; P=0.009). The rates of cardiovascular mortality were 1.2% in everolimus group and 1.6% in paclitaxel group (OR: 0.85; P=0.43). Patients receiving everolimus-eluting stents had significantly lower myocardial infarction events and target vessel revascularization as compared to paclitaxel-eluting stents. Interpretation. Everolimus compared to paclitaxel-eluting stents reduced the incidence of early, late, and very late stent thrombosis as well as target vessel revascularization.

Abstract Purpose To compare the effects of paclitaxal-coated balloon (PCB) versus conventional balloon (CB) on side branch (SB) lesion and cardiovascular outcomes in patients with de novo true bifurcation lesions. Methods In total, 219 patients with de novo true bifurcation lesions were enrolled and divided into PCB group (102 cases) and CB group (117 cases) according to angioplasty strategy in SB. Drug-eluting stent (DES) was implanted in main vessel (MV) for each subject. All subjects underwent a 12-month follow-up for late lumen loss (LLL), restenosis and major adverse cardiovascular events (MACE) after percutaneous coronary intervention (PCI). MACEs included cardiac death, nonfatal myocardial infarction and angina pectoris. Results There were no differences in diameter, minimum lumen diameter (MLD) and stenosis for bifurcation lesions between the two groups before and immediately after PCI (P > 0.05). After 12-month follow-up, no differences occurred in MV-MLD and MV-LLL between the two groups (P > 0.05); SB-MLD in PCB group was higher than that in CB group (1.97 ± 0.36 mm vs. 1.80 ± 0.43 mm, P = 0.007); SB-LLL in PCB group was lower than that in CB group (0.11 ± 0.18 mm vs. 0.19 ± 0.25 mm, P = 0.024). Multivariate COX analyses indicated that PCB group had lower MACE risk than CB group (HR = 0.480, 95%CI 0.244–0.941, P = 0.033). Conclusion PCB could decrease SB-LLL and MACE risk in patients with de novo true coronary bifurcation lesion 12 months after single-DES intervention.

<b><i>Background:</i></b> The impact of diabetes mellitus (DM) on clinical outcomes after percutaneous coronary intervention (PCI) for unprotected left main (ULM) distal bifurcation lesions in patients with chronic kidney disease (CKD) is poorly understood in the era of drug-eluting stents (DESs). <b><i>Objective:</i></b> We assessed the impact of DM on clinical outcomes after PCI for ULM distal bifurcation lesions in CKD patients compared to patients without DM. <b><i>Methods:</i></b> We identified 1,832 consecutive patients who underwent PCI for ULM lesions at New Tokyo Hospital, Matsudo, Japan, San Raffaele Scientific Institute, Milan, Italy, and EMO-GVM, Centro Cuore Columbus, Milan, Italy between January 2005 and August 2015. Of the 1,832 patients, 1,391 were treated with DESs. We excluded 750 patients without CKD and 89 hemodialysis patients. Finally, 552 patients with CKD were included: 219 with DM (DM group) and 333 without DM (no DM group). The primary endpoint was target lesion failure (TLF) at 5 years. TLF was defined as a composite of cardiac death, target lesion revascularization (TLR), and myocardial infarction. <b><i>Results:</i></b> Patients in the DM group were more likely to have hypertension, dyslipidemia, peripheral artery disease, and lower ejection fraction and were more frequently using insulin for DM. The TLF rate during the follow-up period was significantly higher in the DM than in the no DM group (adjusted hazard ratio [HR] 1.50; 95% confidence interval [CI] 1.06–2.13; <i>p</i> = 0.023). Cardiac mortality was comparable between both groups (adjusted HR 1.11; 95% CI 0.63–1.95; <i>p</i> = 0.71). The TLR rate was significantly higher in the DM group than in the no DM group (adjusted HR 1.69; 95% CI 1.12–2.54; <i>p</i> = 0.012). <b><i>Conclusion:</i></b> DM is strongly associated with adverse event after PCI for ULM distal bifurcation lesions in CKD patients compared to those without DM.

AbstractSide branch occlusion has been implicated as a complication after percutaneous coronary intervention in coronary bifurcation lesions. The role of carina bifurcation angle as one of the characteristics of the coronary bifurcation lesions in causing side branch occlusion after percutaneous coronary intervention is still debated. This study aims to assess the correlation between carina bifurcation angles as one of the characteristics of the coronary bifurcation lesions and side branch occlusion in elective percutaneous coronary intervention. This is a cross-sectional study which utilizes CAAS 5.1 software to measure carina bifurcation angle. We collected 113 lesions in 108 patients that met the inclusion criteria from January 2016 to October 2016. Side branch occlusion occurred in 15 lesions (13.3%), with median carina bifurcation angle 19.17 degrees (p < 0.001). Multivariate analysis showed there is a correlation between carina bifurcation angle with side branch occlusion, OR (odds ratio) 0.86 (95% CI [confidence interval]: 0.80–0.92) with ≤ 33.71 degrees cut off value. Increased risk of side branch occlusion was found in small carina bifurcation angle.

AimsWe aimed to uncover the 5-year real world outcomes of patients with significant left mainstem (LMS) disease managed with percutaneous coronary intervention (PCI), coronary artery bypass graft (CABG) or medical management.MethodsWe identified patients with LMS disease in 2012 and analysed baseline characteristics and outcomes in the following 5 years.Results119 patients were identified, 62% (74) received CABG and 12% (14) received PCI and 26% (31) were medically managed. In PCI versus CABG, there was no significant difference in age and Synergy between PCI with Taxus and Cardiac Surgery score but there were significantly higher rates of pretreatment heart failure (ejection fraction 42%±10 vs 52%±13p=0.01). Overall major adverse cardiovascular event (MACE) being a composite of stroke, myocardial infarction (MI), target vessel revascularisation and all-cause mortality were not statistically different but numerically higher in the PCI group (36% (5) vs 23% (17) p=0.12). Medically managed patients were significantly older than those that were revascularised (PCI or CABG n=88; 75±11 vs 69±9 years p=0.01). They also had higher MACE (74% (23) vs 25% (22) p=0.000002) driven by MI (19% (6) vs 2% (1) p=0.01) and all-cause mortality (52% (16) vs 19% (17) p=0.01) compared with those with revascularisation.ConclusionsThe bleak outcomes of medical management in LMS disease are reflective findings from studies performed from several decades ago. Our findings show that there is still a role for PCI in the management of LMS disease in selected patients.

Abstract Background Bifurcation lesions represent 20% of all coronary lesions treated by percutaneous coronary interventions (PCI). Although provisional technique with 1 stent in the main branch and balloon angioplasty of the side branch is considered the standard approach, the implantation of 2 stents is often being pursued with a wide variety of bifurcation stenting techniques. We thus conducted a systematic review and network meta-analysis of randomized clinical trials (RCTs) to compare clinical cardiovascular outcomes involving stenting techniques in coronary bifurcation lesions. Methods We searched on Pubmed, Google Scholar, Embase and Cochrane Library, up to October 2018 for published and unpublished RCTs that compared clinical cardiovascular outcomes in patients with bifurcation lesions treated with 7different techniques (crush [Cr]; culotte [Cu]; double kissing crush [DKCr], mini-crush [mCr], routine T-stenting [RTS], T-stenting and small protrusion [TAP], and provisional (1 stent technique)). We performed a frequentist fixed-effect network meta-analysis to estimate relative risks (RR) of major adverse cardiovascular events (“MACE”, typically defined as death, myocardial infarction and target vessel revascularization), target vessel revascularization (TVR), target lesion revascularization (TLR), and stent thrombosis (ST). Results We identified 14 studies, yielding data on 4285 patients. DKCr and mCr yielded significant reductions in MACE, TVR, and TLR when compared with the 1-stent technique (RR 0.31–0.55 [all P<0.01] and RR 0.42–0.45 [all P<0.02], respectively) and with the rest of the bifurcation techniques (RR 0.44–0.55 [all P<0.05] for DKCr and RR 0.37–0.45 [all P<0.05] for mCr). On the other hand, Cu and Cr were associated with an increased risk for ST compared to 1-stent technique (RR 3.25–4.27 [both P<0.05]) and to DKCr (RR 3.02–3.99 [both P<0.05]). We found no heterogeneity nor inconsistency between studies. Conclusions The various PCI bifurcation stenting techniques are associated with different cardiovascular outcomes, with double kissing crush and mini crush being more effective than others, including the 1-stent approach, whereas culotte and crush are associated with increased risk of stent thrombosis.
