Bifurcation lesions are common and associated with higher risks of major cardiac events and restenosis after percutaneous coronary intervention (PCI). Treatment requires understanding of lesion characteristics, stent design and therapeutic options. We review the evidence for provisional vs 2-stent techniques. We conclude that provisional stenting is suitable for most bifurcation lesions. We detail situations where a 2-stent technique should be considered and the steps for performing each of the 2-step techniques. We review the importance of lesion preparation, intracoronary imaging, proximal optimization (POT) and kissing balloon inflation

Introduction: Percutaneous coronary intervention (PCI) for the treatment of bifurcation lesions in acute coronary syndrome (ACS) setting is a high-risk procedure and is associated with higher periprocedural complications and a lower procedural success rate. Hypothesis: We assessed the hypothesis that PCI for bifurcation stenting in ACS is safe and effective as in non ACS condition. Methods: Out of 986 patients who underwent PCI for ACS, 144 (14.6%) patients having bifurcation lesion were included in study. Provisional stenting was favored whenever feasible (86.8%), elective bifurcation stenting (2 stent strategy) was reserved for significant long segment side branch involvement (13.2%). Occurrence of major adverse cardiac events (MACE), a composite of cardiac death, myocardial infarction, target lesion revascularization, and stent thrombosis, was observed during follow up. Results: LAD bifurcation was the most common lesion (49.3%), most common Medina class was 1, 1, 1 (52.1%), 70.8% of the procedures were done transradially, angiographic success rate for main vessel was 97.9% and there was no periprocedural mortality or stroke. There was no significant difference regarding risk factors (age, hypertension, diabetes mellitus, dyslipidemia and smoking history; p > 0.05) between 1 stent and 2-stent groups. Median Syntax score was 14(IQR 10-20) in 1 stent group and 22(IQR 17-25) in 2 stent group. The 2-stent group had higher proportion of left main coronary involvement as compared to 1 stent group (47.4 vs 24.8%). Crush was preferred elective 2-stent strategy as compared to TAP in provisional approach (used in 73.7 and 62.5%). Final kissing balloon inflation was used in 38.4% patients in 1- stent group, while it was utilised in all patients with 2- stent approach. Post procedural side branch diameter stenosis (by QCA) differed significantly between the 2 groups (1-stent vs 2-stent, 34.9 vs 6.4%).The rate of MACE was similar in both groups ( total 7 MACE events; median follow-up of 18 months) but radiation dose and contrast volume utilization were significantly more in 2-stent group. Conclusions: PCI for bifurcation lesions had acceptable success and MACE rate even during ACS settings and whenever feasible, provisional stenting should be preferred approach.

Stent Diameter

Coronary bifurcations are prone to the development of atherosclerosis. They pose technical difficulties for angioplasty treatment and are a predictor of stent thrombosis and restenosis. Treatment of coronary bifurcations is still subject to debate, especially when the side branch (SB) is large, not easily accessible and narrowed by a long lesion. There is currently no indexed treatment for this type of lesion (Medina classification), as the strategy of provisional SB stenting with drug-eluting stents (DES) has proved to be equally efficient as the dualstent technique. Complex techniques are associated with poor outcome in certain lesion types, such as T-stenting when the angle between the two distal branches is small or the crush and culotte technique in the presence of an open angle. Provisional SB stenting may be used when primary dual stenting is required, with a low risk of failure provided that the following guidelines are implemented: stenting of the main branch through the protected SB with a stent diameter adapted to the distal main branch, immediate optimisation of the proximal stent segment (Finet’s law), guidewire exchange, kissing balloon inflation with non-compliant balloons selected according to the diameter of the distal branches and T-stenting of the SB before final kissing inflation.

Abstract Background/Introduction The Medina classification is the most widespread method to describe bifurcation lesions. However, little is known regarding the prognostic impact of the classification. Purpose To assess the prognostic significance of the Medina classification following percutaneous coronary intervention (PCI). Methods The study included 738 consecutive patients from a prospective bifurcation registry. There were 609 patients (82.5%) with “true bifurcation” (TB) lesions (Medina class 1.0.1, 1.1.1, 0.1.1) and 129 (17.5%) in all other categories (“non-true bifurcation” = NTB). We compared rates of death and major adverse cardiac events (MACE: cardiac death, myocardial infarction, or target vessel revascularization) at 12 months and 3 years. Results Patients with TB had lower rates of previous bypass surgery (9.4% vs. 12.2%, p=0.03) and hyperlipidemia (75.2% vs. 79.0%, p=0.04). TB lesions were more likely to be calcified (33.8% vs. 28.2%, p=0.03) and ulcerated (8.9% vs. 3.4%, p<0.01). At 12 months, mortality was numerically higher for TB PCI (4.1% vs. 2.0%m p=0.052) and MACE rates were higher (13.2% vs. 5.2%, p<0.001). At 3 years, both all cause death (10.1% vs. 4.9%, p=0.002), as well as rates of MACE (27.2% vs. 11.6%, p<0.001) were higher for TB PCI (Figure 1). After performing regression analysis, TB remained an independent predictor for poor outcomes (OR- 3.93 at 12 months, CI 1.45–10.66, p=0.007, OR-3.26 at 3 years, CI 1.47–7.25, p=0.004 for MACE). Conclusions TB lesions, according to the Medina classification, portend worse prognosis for patients undergoing bifurcation PCI. This may guide prognostication and decision making in treatment.

Procedural Success

Coronary artery bifurcation lesions remain challenging despite significant advancements in stent technology and development of specific bifurcation stenting approaches. Optical coherence tomography (OCT) is the intracoronary imaging technique with the highest resolution and can generate automatically contoured lumen areas across the variable geometry of bifurcation lesions. Knowledge of plaque severity and composition facilitates planning of the best strategy for percutaneous coronary intervention (PCI) and stenting. In particular, the provisional stent strategy preferred in this context can be modified when there is high risk of side-branch compromise at the ostium after main vessel stenting. OCT is unique because it allows the identification of the site of guide wire crossing, an important determinant of the final result. OCT can also be used to assess the procedural success of new dedicated bifurcation stent technologies and for the evaluation at follow-up of potential predictors of stent thrombosis, including stent malapposition, stent under-expansion and stent-edge dissection. Finally, the development of 3D OCT allows a better evaluation of coronary anatomy – particularly of side branch ostium that is difficult to visualise by 2D OCT – further improving the value of this technique in guiding PCI in these patients.

Cardiac Adverse Events

SummaryThe single nucleotide polymorphism (SNP) rs342293 has been shown to influence platelet number and mean platelet volume (MPV). We investigated the association between the rs342293 polymorphism and cardiovascular outcome in a prospective cohort study. The rs342293 polymorphism was analysed in 404 patients with coronary artery disease undergoing percutaneous coronary intervention. The rates of cardiac adverse events were recorded during two years of follow-up. The polymorphism was associated with MPV (median 10.1 fL, interquartile range [IQR]: 9.6 to 10.6 in patients with the CC-allele vs 10.4 fL, IQR: 9.9 to 11.1 in G>C SNP carriers; p<0.001), but not with platelet count. Survival analysis indicated that carriers of the rs342293 G variant had a substantially higher risk to develop cardiac adverse events compared with wild type carriers during two years of follow-up (33% vs 22%; adjusted hazard ratio = 1.63, 95% confidence interval = 1.06–2.52, p=0.027). The rs342293 SNP could explain 2.9% of the variability in MPV (p=0.01). In conclusion, patients undergoing coronary stenting who carry the G-variant of the rs342293 SNP which is associated with larger MPV are at higher risk for adverse cardiovascular outcome.
