- Abstract
The multicenter and randomized DEFINITION II (Two-Stent vs Provisional Stenting Techniques for Patients With Complex Coronary Bifurcation Lesions) trial showed less 1-year target lesion failure (TLF) after a 2-stent approach for complex coronary bifurcation lesions compared with provisional stenting (PS). The authors report the 3-year clinical outcome of the DEFINITION II trial. The aim of the present study was to investigate the difference in TLF at 3 years after a planned 2-stent approach vs PS for complex coronary bifurcation lesions stratified by DEFINITION (Definitions and Impact of Complex Bifurcation Lesions on Clinical Outcomes After Percutaneous Coronary Intervention Using Drug-Eluting Stents) criteria. A total of 653 patients with complex coronary bifurcation lesions were randomly assigned to either the 2-stent group or the PS group in the DEFINITION II trial and were followed for 3 years. The primary endpoint was the occurrence of TLF at 3 years. Stent thrombosis was the safety endpoint. At 3 years, TLF had occurred in 52 patients (16.0%) in the PS group and in 34 (10.4%) patients in the 2-stent group (HR: 0.63; 95% CI: 0.41-0.97; P = 0.035), driven mainly by increased target vessel myocardial infarction (8.0% vs 3.7%; HR: 0.45; 95% CI: 0.23-0.89; P = 0.022) and target lesion revascularization (8.3% vs 4.3%; HR: 0.50; 95% CI: 0.26-0.96; P = 0.038). There was no difference in TLF between the 2 groups between year 1 and year 3. For patients with complex coronary bifurcations who reach 1-year postprocedure without experiencing endpoint events, there is still a risk for future events. The type of procedure performed initially is no longer a future event risk determinant.

ObjectivesThe present study established criteria to differentiate simple from complex bifurcation lesions and compared 1-year outcomes stratified by lesion complexity after provisional stenting (PS) and 2-stent techniques using drug-eluting stents.BackgroundCurrently, no criterion can distinguish between simple and complex coronary bifurcation lesions. Comparisons of PS and 2-stent strategies stratified by lesion complexity have also not been reported previously.MethodsCriteria of bifurcation complexity in 1,500 patients were externally tested in another 3,660 true bifurcation lesions after placement of drug-eluting stents. The primary endpoint was the occurrence of a major adverse cardiac event (MACE) at 12 months. The secondary endpoint was the rate of stent thrombosis (ST).ResultsComplex (n = 1,108) bifurcation lesions were associated with a higher 1-year rate of MACE (16.8%) compared with simple (n = 2,552) bifurcation lesions (8.9%) (p < 0.001). The in-hospital ST and 1-year target lesion revascularization rates after 2-stent techniques in the simple group (1.0% and 5.6%, respectively) were significantly different from those after PS (0.2% [p = 0.007] and 3.2% [p = 0.009], respectively); however, 1-year MACE rates were not significantly different between the 2 groups. For complex bifurcation lesions, 2-stent techniques had lower rates of 1-year cardiac death (2.8%) and in-hospital MACE (5.0%) compared with PS (5.3%, p = 0.047; 8.4%, p = 0.031).ConclusionsComplex bifurcation lesions had higher rates of 1-year MACE and ST. The 2-stent and PS techniques were overall equivalent in 1-year MACE. However, 2-stent techniques for complex lesions elicited a lower rate of cardiac death and in-hospital MACE but higher rates of in-hospital ST and revascularization at 1 year for simple lesions.

- Abstract
Objectives The present study aimed to analyze the incidence of SF and its correlation with clinical events after DES implantation and the outcome of re-intervention for symptomatic in-stent restenosis (ISR) induced by stent fracture (SF). Background SF is associated with a high rate of clinical events after the implantation of drug-eluting stents (DES). However, the chronological rate of SF and the effect of SF on clinical outcomes from a large patient population remain underreported. Methods A total of 6,555 patients with 16482 DES in 10751 diseased vessels and surveillance angiography between November 2003 and January 2014 were prospectively studied. The primary endpoints included the incidence of SF, in-stent restenosis (ISR), target lesion revascularization (TLR), and definite stent thrombosis (ST) at the end of follow-up before and after propensity score matching. Clinical outcomes after TLR were also followed up. Results The SF rate was detected in 803 (12.3%) patients, 3,630 (22.0%) stents, and 1,852 (17.2%) diseased vessels. SF increased over time. SF was associated with higher unadjusted rates of ISR (42.1%), TLR (24.8%, n = 379), and definite ST (4.6%) compared with stents without fracture (10.7%, 6.6%, and 1.03%, all p < 0.001), and the differences remained significant after propensity score matching (all p < 0.05). There was no significant difference in any-cause or cardiac mortality between patients with and without SF. After 1,523 days of follow-up since the first surveillance angiography, repeat ISR was detected in 90 of 379 (23.8%) stents after reintervention, and 6 (7.5%) stents required repeat TLR. Conclusions SF is more frequently observed after DES implantation. TLR was required in almost one-fourth of fractured stents. Increased events in the SF group did not translate into a difference in mortality compared with the non-SF group. Reintervention was associated with acceptable clinical results.

- Abstract
Objectives The present study aimed to investigate the difference in major adverse cardiac events (MACE) at 3 years after double-kissing (DK) crush versus culotte stenting for unprotected left main distal bifurcation lesions (LMDBLs). Background The multicenter and randomized DKCRUSH-III (Comparison of double kissing crush versus culotte stenting for unprotected distal left main bifurcation lesions: results from a multicenter, randomized, prospective study) showed that DK crush stenting was associated with fewer MACE at 1-year follow-up in patients with LMDBLs compared with culotte stenting. Here, we report the 3-year clinical outcome of the DKCRUSH-III study. Methods A total of 419 patients with LMDBLs who were randomly assigned to either the DK crush or culotte group in the DKCRUSH-III study were followed for 3 year. The primary endpoint was the occurrence of a MACE at 3 years. Stent thrombosis (ST) was the safety endpoint. Patients were classified by simple and complex LMDBLs according to the DEFINITION (Definition and Impact of Complex Bifurcation Lesions on Clinical Outcomes After Percutaneous Coronary Intervention Using Drug-Eluting Stents) study criteria. Results At 3 years, MACE occurred in 49 patients the culotte group and in 17 patients in the DK crush group (cumulative event rates of 23.7% and 8.2%, respectively; p < 0.001), mainly driven by increased myocardial infarction (8.2% vs. 3.4%, respectively; p = 0.037) and target-vessel revascularization (18.8% vs. 5.8%, respectively; p < 0.001) between groups. Definite ST rate was 3.4% in the culotte group and 0% in the DK crush group (p = 0.007). Complex LMDBLs were associated with a higher rate of MACE (35.3%) at 3 years compared with a rate of 8.1% in patients with simple LMDBLs (p < 0.001), with an extremely higher rate in the culotte group (51.5% vs. 15.1%, p < 0.001). Conclusions Culotte stenting for LMDBLs was associated with significantly increased rates of MACE and ST.

- Abstract
Objectives This study sought to compare the outcomes of fractional flow reserve (FFR)–guided and angiography (Angio)–guided provisional side-branch (SB) stenting for true coronary bifurcation lesions. Background Angio-guided provisional SB stenting after stenting of the main vessel provides favorable outcomes for the majority of coronary bifurcation lesions. Whether an FFR-guided provisional stenting approach is superior has not been studied. Methods A total of 320 patients with single Medina 1,1,1 and 0,1,1 coronary bifurcation lesions undergoing stenting with a provisional SB approach were randomly assigned 1:1 to Angio-guided and FFR-guided groups. SB stenting was performed for Thrombolysis In Myocardial Infarction flow grade <3, ostial SB stenosis >70%, or greater than type A dissection after main vessel stenting in the Angio-guided group and for SB-FFR <0.80 in the FFR-guided group. The primary endpoint was the 1-year composite rate of major adverse cardiac events (cardiac death, myocardial infarction, and clinically driven target vessel revascularization). Results Comparing the Angio-guided and FFR-guided groups, treatment of the SB (balloon or stenting) was performed in 63.1% and 56.3% of lesions respectively (p = 0.07); stenting of the SB was attempted in 38.1% and 25.9%, respectively (p = 0.01); and, when attempted, stenting was successful in 83.6% and 73.3% of SBs, respectively (p = 0.01). The 1-year composite major adverse cardiac event rate was 18.1% in both groups (hazard ratio: 0.91, 95% confidence interval: 0.48 to 1.88; p = 1.00). The 1-year target vessel revascularization and stent thrombosis rates were 6.9% and 5.6% (p = 0.82) and 1.3% and 0.6% (p = 0.56) in the Angio-guided and FFR-guided groups, respectively. Conclusions In this multicenter, randomized trial, angiographic and FFR guidance of provisional SB stenting of true coronary bifurcation lesions provided similar 1-year clinical outcomes.

Background Polymer-free sirolimus- and probucol-eluting stents ( Real Dual drug-eluting stents [ DES]) is as effective as first-generation DES in treating coronary artery stenosis. It is unknown whether sirolimus-eluting stents containing biodegradable polymer ( Excel) would be superior to real Dual DES. This study aimed to investigate the difference in target vessel revascularization ( TVR) at 12 months in patients with coronary artery disease treated by the implantation of Dual DES or Excel stents. Methods Three hundred and forty-six patients with de novo coronary artery disease were recruited from six centers in China and randomly assigned to either the Dual DES or the Excel group. The primary endpoint was the occurrence of TVR at 12 months. The secondary endpoint was angiographic in-stent restenosis and late lumen loss at 13 months. Stent thrombosis ( ST) served as the safety endpoint. Dual anti-platelet therapy ( DAPT) was prescribed for 6 months. Results Clinical follow-up for 12 months and repeat angiography at 13 months were available in 100% and >90% of patients, respectively. The ISR and in-stent late loss were significantly different between the Excel (3.1%, 0.09 ± 0.11 mm) and the Dual DES (19.5%, 0.36 ± 0.32 mm, P < 0.001, P < 0.001, respectively) groups. The TVR (3.5%) in the Excel group was significantly less than in the Dual DES group (13.9%, P = 0.001). The ST rate beyond 12 months in the Dual DES group was 0%, and this was 1.2% in the Excel group ( P = 0.499). Conclusions The Excel stent was statistically superior to the Dual DES in terms of restenosis, late loss, and TVR for long lesions. [ABSTRACT FROM AUTHOR]

Multidrug resistance protein 3 ( MPR3), encoded by the ATP-binding cassette, subfamily C ( CFTR/ MRP), member 3 ( ABCC3) gene, functions as an important drug efflux transporter. The ABCC3 -211 C/ T polymorphism is associated with decreased MRP3 mRNA expression, and low MRP3 mRNA expression is associated with increased clopidogrel response in patients. The aim of the present study was to determine whether the -211 C/ T polymorphism is associated with altered antiplatelet effects and clinical outcomes in clopidogrel-treated patients., A subcohort of 249 patients not carrying the CYP2C19* 2, * 3 or * 17 variant was identified from a total of 617 consecutive clopidogrel-treated patients undergoing percutaneous coronary intervention and then categorized into three groups on the basis of their ABCC3 -211 C/ T genotype. Baseline data, clinical characteristics and DNA samples were collected for all patients. Light transmittance aggregometry was used to determine ADP-induced maximum platelet aggregation ( MPA) in blood samples obtained from patients on Day 3 after starting daily clopidogrel maintenance doses. Genotyping of CYP2C19* 2, * 3 and * 17 variants and the ABCC3 -211 C/ T polymorphism was performed using matrix-assisted laser desorption ionization time-of-flight ( MALDI- TOF) mass spectrometry. The primary clinical end-point was a definite stent thrombosis ( ST) episode, whereas secondary end-points were other major adverse cardiovascular events within 12 months after stenting., There were no differences in MPA values according to ABCC3 -211 C/ T genotype. A multiple linear regression model revealed that the ABCC3 -211 C/ T polymorphism was not independently associated with ADP-induced MPA measurements; a multiple logistic regression model revealed that carrying the ABCC3 -211 C allele was not associated with the risk of developing an ST event in clopidogrel-treated patients not harbouring CYP2C19* 2, * 3 and * 17 variants., In conclusion, the ABCC3 -211 C/ T polymorphism seems not to be associated with altered antiplatelet effects and clinical outcomes in clopidogrel-treated patients.

Objectives: The present study aimed to investigate the difference in major adverse cardiac events (MACE) at 12 months in patients with coronary bifurcation lesions after double kissing double crush (DK crush) or provisional stenting (PS) techniques. Background: Provisional side branch (SB) stenting is preferable to DK crush because it has been associated with fewer complications. It is unknown which strategy would provide the best results. Methods: From April 2007 to June 2009, 370 unselected patients with coronary bifurcation lesions from 7 Asian centers were randomly assigned to either the DK or the PS group. Additional SB stenting in PS was required if final results were suboptimal. The primary end point was the occurrence of MACE at 12 months, including cardiac death, myocardial infarction, or target vessel revascularization (TVR). Secondary end point was the angiographic restenosis at 8 months. Results: There were 3 procedural occlusions of SB in the PS group. At 8 months, angiographic restenosis rates in the main vessel and SB were significantly different between the DK (3.8% and 4.9%) and the PS groups (9.7% and 22.2%, p = 0.036 and p < 0.001, respectively). Additional SB stenting in the PS group was required in 28.6% of lesions. TVR was 6.5% in the DK group, occurring significantly less often than in the PS group (14.6%, p = 0.017). There were nonsignificant differences in MACE and definite stent thrombosis between the DK (10.3% and 2.2%) and PS groups (17.3%, and 0.5%, p = 0.070 and p = 0.372, respectively). Conclusions: DK crush was associated with a significant reduction of TLR and TVR in this unselected patient population. However, there was no significant difference in MACE between DK and the PS groups.

Abstract: The widespread use of clopidogrel alone or in combination with aspirin has significantly benefited patients with acute coronary syndrome who are managed medically or by percutaneous coronary intervention and stent implantation, greatly improving their survival. Emerging data have documented that the clopidogrel response may vary from person to person and even from disease to disease, and that genetic and nongenetic factors contribute to that variability. Genetic polymorphisms affecting clopidogrel metabolic bioactivation and platelet function may be responsible, each exerting a small effect. CYP2C19 *2, *3 and *17, CYP2C9 *2 and *3, MDR1*2, and functional variants in the genes encoding platelet membrane receptors and intracellular signaling proteins are involved, and other genetic factors remain to be identified. In addition, nongenetic factors may be influential covariates, such as ethnicity, gender, age, body weight, co-existing diseases, drug–drug interactions, and other factors to be determined. Each piece of the puzzle would be useful to bridge and delineate identified knowledge gaps and to determine future research needs for the risk prediction of fatal complications associated with inadequate clopidogrel therapy in patient care.
