Provisional Stenting

Coronary bifurcation lesions represent an area of ongoing challenges in interventional cardiology, mainly due to the higher rate of residual stenosis and restenosis at the side branch ostium. Multiple two-stent bifurcation strategies, including T-stenting, V-stenting, simultaneuos kissing stenting, culotte stenting and classic crush techniques, have no advantages over one-stent techniques. This led to provisional stenting being considered as a mainstream approach, based on the results of numerous randomised trials. Dedicated bifurcation stents have been designed specifically to treat coronary bifurcations with the aim of addressing some of the shortcomings of the conventional percutaneous approach and facilitating the provisional approach. The development of more drug-eluting platforms and larger studies with control groups demonstrating their clinical applicability, efficacy and safety are required before these stents are widely incorporated into daily practice.

Abstract Background Provisional side branch (SB) stenting is correlated with target-vessel myocardial infarction (TVMI) in patients with coronary bifurcation lesions. However, the underlying mechanisms remain unknown. Objectives We aimed to determine the correlation of SB lesion length with vulnerable plaques using optical coherence tomography (OCT) and TVMI in patients with coronary bifurcation lesions treated by a provisional approach. Methods A total of 405 patients with 405 bifurcation lesions who underwent pre-PCI OCT imaging of both main vessel (MV) and SB was prospectively enrolled. Patients were defined as Long-SB lesion (SB lesion length ≥10 mm) and Short-SB lesion (SB lesion length <10 mm) groups according to quantitative coronary analysis and were also stratified by the presence of vulnerable plaques based on OCT findings. The primary endpoint was the occurrence of TVMI after provisional stenting at one-year follow-up. Results 178 (43.9%) patients had long SB lesions. Vulnerable plaques predominantly localized in the main vessel (MV) and more frequently in the Long-SB lesion group (42.7%) compared to 24.2% in the Short-SB lesion group (p<0.001). At one-year follow-up after provisional stenting, there were 31 (8.1%) TVMIs, with 11.8% in the Long-SB lesion group and 4.4% in the Short-SB lesion group (p=0.009), leading to significant difference in target lesion failure between two groups (15.2% vs. 6.6%, p=0.007). The rate of cardiac death, revascularization, and stent thrombosis was comparable between study groups. By multivariate regression analysis, long SB lesion length (p=0.011), presence of vulnerable plaques in the polygon of confluence (p=0.001), and true coronary bifurcation lesions (p=0.004) were three independent factors of TVMI. Conclusions Long-SB lesion length with MV vulnerable plaques predict increased TVMI after provisional stenting in patients with true coronary bifurcation lesions. Further study is warranted to identify the better stenting techniques for coronary bifurcation lesions with long lesion in the SB Kaplan-Meier survival curve Funding Acknowledgement Type of funding source: Foundation.

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.
