We assessed long-term outcomes after left main coronary artery (LMCA) stenting based on lesion types and stenting strategies. In the Assessing Optimal percutaneous coronary Intervention for Left Main Coronary Artery stenting registry, we evaluated 1,607 consecutive patients undergoing stent implantation for unprotected LMCA lesions (bifurcation lesions: n = 1318 and nonbifurcation lesions: n = 289). Among the bifurcation lesions, 1,281 lesions were treated with stenting across the bifurcation (bifurcation 1-stent strategy: n = 999 or bifurcation 2-stent strategy: n = 282)...

We report on two cases in which Y-shaped coronary bifurcations were treated with the use of Bioresorbable scaffolds. The first case was of a 50-year-old man with NSTEMI. Coronary angiography showed stenosis involving a Y-shaped bifurcation of proximal to mid LAD and diagonal. The lesion was wired using two 0.14 BMW guide wires, followed by serial pre-dilatation of LAD and Diagonal branch. The stent into proximal LAD was deployed first as a skirt (3.5 × 12 BVS). Stent was post-dilated. A second 2.5 × 28 BVS was deployed into diagonal branch, protruding backwards; along with a 2...

BACKGROUND: Percutaneous coronary intervention (PCI) is most commonly guided by angiography alone. Intravascular ultrasound (IVUS) guidance has been shown to reduce major adverse cardiovascular events (MACE) after PCI, principally by resulting in a larger postprocedure lumen than with angiographic guidance. Optical coherence tomography (OCT) provides higher resolution imaging than does IVUS, although findings from some studies suggest that it might lead to smaller luminal diameters after stent implantation...

AIMS: Percutaneous coronary intervention (PCI) of bifurcation lesions can be performed using various techniques. The aim of this study was to analyse the outcome of various techniques of bifurcation stenting in all patients undergoing bifurcation stenting at one large intervention centre in 2013, taking into account that more complex lesions might more often warrant a two-stent technique. METHODS AND RESULTS: This retrospective study included 260 consecutive patients who underwent non-primary PCI of a bifurcation lesion at the Catharina Hospital, Eindhoven, in 2013...

OBJECTIVES: The aim of this study was to assess the impact of operator experience on prognosis after left main coronary artery (LM) percutaneous coronary intervention (PCI). BACKGROUND: LM PCI can be technically challenging and potentially risky considering the amount of supplied myocardium. METHODS: Consecutive patients who underwent unprotected LM PCI at a single institution were included and compared according to whether the primary operator was an experienced, high-volume LM operator (defined as an operator who performed at least 15 LM PCIs per year for at least 3 consecutive years) or not...

We report a case of percutaneous coronary intervention in a bifurcation lesion involving left circumflex (LCx) artery and 2 major posterolateral (PL) arteries. The target LCx had diffuse long and severely calcified lesion with the acute takeoff angle from the left main. Despite adequate lesion preparation with rotational atherectomy and balloon angioplasty, the stent was not deliverable, even with deep intubation of 7Fr-guiding catheter. Conventional use of guiding extension catheter (GEC) would have required removal of a wire from at least one PL because of the device interference in the GEC...

Drug-eluting balloons (DEB) may be considered as a "quiet revolution" in percutaneous coronary interventions. Early-generation DEB eluting paclitaxel proved to be very effective in animal models to reduce neointimal hyperplasia. Areas covered: Review of DEB efficacy in patients with coronary de novo lesions and in-stent restenosis (ISR). Expert opinion: Many randomized clinical trials and meta-analyses have demonstrated the value of DEB in patients with ISR. In this setting, DEB are safe and effective with clinical and angiographic results superior to plain balloon angioplasty and at least equivalent to first generation drug-eluting stents (DES)...

Bifurcation lesions are a therapeutic challenge in the interventional treatment of coronary artery disease. Thus, consideration of anatomical aspects and selection of the most appropriate strategy for an individual bifurcation have an impact on the interventional outcome. Accordingly, assessment of the type of bifurcation stenosis, including the relevance of the side branches, vessel diameter and the angle between the two branches are critical for the optimal choice of interventional strategy. The fractional flow reserve (FFR) is a parameter that provides a measure of the severity of coronary stenosis and despite some limitations, FFR can be applied to bifurcation lesions...

BACKGROUND: The treatment strategy for in-stent restenosis (ISR) with bifurcation lesions has not been well explored. We examined the clinical outcomes between final kissing balloon technique (FKBT) after stent implantation and single-stent implantation without FKBT for bifurcation ISR lesions. METHODS: We identified 115 consecutive ISR with bifurcation lesions among 108 patients who underwent drug-eluting stent implantation. The patients were divided into the FKBT group (34 patients, 35 lesions) and the non-FKBT group (74 patients, 80 lesions)...

Coronary bifurcations are frequent and account for approximately 20% of all percutaneous coronary interventions. Nonetheless, they remain one of the most challenging lesion subsets in interventional cardiology in terms of a lower procedural success rate and increased rates of long-term adverse cardiac events. Provisional side branch stenting should be the default approach in the majority of cases and we propose easily applicable and reproducible stepwise techniques associated with low risk of failure and complications...

OBJECTIVE: In patients with multivessel disease and proximal left anterior descending artery (LAD) involvement, the best revascularisation strategy is still unclear. We assess outcomes after coronary artery bypass graft surgery (CABG) and percutaneous coronary intervention (PCI) with drug-eluting stents in a pooled analysis of individual patient-level data of the SYNTAX and BEST randomised trials. DESIGN: Proximal LAD involvement was defined by any lesion ≥ 50% diameter stenosis in the arterial segment starting from the left-main bifurcation up to (and including) the origin of the first major septal branch...

COMMENT
Jacek Bil, Robert J Gil
Bioresorbable vascular scaffolds (BVS) have emerged as an interesting alternative since the presence of the prosthesis in the coronary artery is transient. This technology enables to restore the normal vasomotor tone and allows positive remodeling, simultaneously reducing the trigger for persistent inflammation and facilitating further interventions by percutaneous or surgical means. Absorb BVS(®) is the first generation everolimus-eluting poly-L-lactide (PLLA) bioresorbable scaffold. In recent meta-analyses Absorb BVS(®) was definitely proved to be safe and effective device in the treatment of symptomatic coronary artery disease...

AIMS: In percutaneous coronary intervention for de-novo coronary bifurcation lesions, the optimal technique for provisional side-branch stenting is still a matter of debate. We tested whether in this setting culotte stenting reduces the incidence of restenosis as compared with T-and-protrusion (TAP) stenting. METHODS AND RESULTS: This trial included 300 patients with a coronary bifurcation lesion requiring a side-branch stent. Patients were randomly assigned to culotte stenting or TAP stenting using drug-eluting stents in a 1:1 fashion...

PURPOSE: To assess the feasibility and safety of the 7 French (Fr) Glidesheath Slender for complex transradial (TR) percutaneous coronary interventions (PCI). BACKGROUND: The TR approach is increasingly used worldwide for coronary and peripheral vascular interventions. However, the small size of the radial artery remains an important limitation for the use of large-bore guiding catheters (>6 Fr), restricting thereby the treatment of highly complex lesions through the TR approach...
