    1. Efficacy of the proximal optimization technique on crossover stenting in coronary bifurcation lesions in the 3D-OCT bifurcation registry

      Efficacy of the proximal optimization technique on crossover stenting in coronary bifurcation lesions in the 3D-OCT bifurcation registry

      Aim We sought to investigate the efficacy of the proximal optimization technique (POT) on crossover stenting followed by side branch (SB) dilation under optical coherence tomography guidance in a multicenter registry study. Methods and results A total of 135 bifurcation lesions in 134 patients were divided into POT (n = 52) and non-POT groups (n = 83). The POT was performed before SB dilatation (pre-POT; n = 26), finally (final-POT; n = 12), at both timing (re-POT; n = 13), and uncertain (n = 1). There were no significant intergroup differences in the success rate of guide wire re-crossing (GWR) into the optimal cell (72% vs ...

    2. Data on two- and three-dimensional optical coherence tomography guidance for the treatment for the bifurcation lesion

      Data on two- and three-dimensional optical coherence tomography guidance for the treatment for the bifurcation lesion

      This article comprised the data related to the research article entitled “Feasibility and usefulness of three-dimensional optical coherence tomography guidance for optimal side branch treatment in coronary bifurcation stenting” (Nagoshi et al., In press) [1] . In this article we reports details about two patterns of guide wire (GW) recrossing position after crossover stenting in bifurcation lesion classified with three-dimensional optical coherence tomography (3D-OCT) (Okamura et al., 2014) [2] and follow-up data about the treatment with percutaneous coronary intervention(PCI) for bifurcation lesion in terms of the two- (2D) or 3D-OCT guidance. Subgroup analysis about differences in the parameters between the ...

    3. Impact of Guidewire Recrossing Point into Stent Jailed Side Branch for Optimal Kissing Balloon Dilatation - Corelab 3D Optical Coherence Tomography Analysis

      Impact of Guidewire Recrossing Point into Stent Jailed Side Branch for Optimal Kissing Balloon Dilatation - Corelab 3D Optical Coherence Tomography Analysis

      AIMS: We investigated the influence of the guidewire recrossing point on the incidence of incomplete stent apposition (ISA) after kissing balloon dilatation (KBD), and clinical and angiographic outcome at 9 months in a prospective multicenter registry. METHODS AND RESULTS: One hundred five patients underwent single crossover stenting across the side branch (SB) and subsequent KBD. Jailing configuration of the SB orifice and the guidewire recrossing position were assessed by off-line 3D-OCT in the corelab. We defined the cases that achieved both Link-Free carina configuration and the distal recrossing as the LFD group (54 cases), and the other cases were defined ...

    4. Feasibility and usefulness of three-dimensional optical coherence tomography guidance for optimal side branch treatment in coronary bifurcation stenting

      Feasibility and usefulness of three-dimensional optical coherence tomography guidance for optimal side branch treatment in coronary bifurcation stenting

      Background For the treatment of coronary bifurcation lesions, optimal guidewire (GW) recrossing after main vessel stenting is important for good stent apposition at the side branch (SB) orifice in kissing balloon inflation (KBI). Methods We analyzed 150 bifurcation lesions treated with single stenting following KBI in the three-dimensional optical coherence tomography (3D-OCT) bifurcation registry study (2015–16) and a single center experience (2012–16). OCT examination was performed after GW recrossing to the SB and after KBI. Patients were divided into two-dimensional (2D, n = 78) and 3D groups ( n = 72) according to 2D- or 3D-OCT guidance. GW recrossing position, jailing ...

    5. Optical frequency domain imaging vs. intravascular ultrasound in percutaneous coronary intervention (OPINION trial): one-year angiographic and clinical results

      Optical frequency domain imaging vs. intravascular ultrasound in percutaneous coronary intervention (OPINION trial): one-year angiographic and clinical results

      Aims Optical frequency domain imaging (OFDI) is a recently developed, light-based, high-resolution intravascular imaging technique. Intravascular ultrasound (IVUS) is a widely used, conventional imaging technique for guiding percutaneous coronary intervention (PCI). We aimed to demonstrate the non-inferiority of OFDI-guided PCI compared with IVUS-guided PCI in terms of clinical outcomes. Methods and results We did a prospective, multicentre, randomized (ratio 1:1), active-controlled, non-inferiority study to compare head-to-head OFDI vs. IVUS in patients undergoing PCI with a second generation drug-eluting stent. The primary endpoint was target vessel failure defined as a composite of cardiac death, target-vessel related myocardial infarction, and ischaemia-driven ...
