Optical frequency domain imaging (OFDI) is a recently developed, light-based, high-resolution intravascular technique. Intravascular ultrasound (IVUS) widely used, conventional technique for guiding percutaneous coronary intervention (PCI). We aimed to demonstrate the non-inferiority of OFDI-guided PCI compared with IVUS-guided in terms clinical outcomes. did prospective, multicentre, randomized (ratio 1:1), active-controlled, study compare head-to-head OFDI vs. IVUS patients undergoing...
We aimed to investigate the influence of guidewire recrossing point on incidence incomplete stent apposition (ISA) after kissing balloon dilatation (KBD), and also clinical angiographic outcome at nine months in a prospective multicentre registry.One hundred five patients underwent single crossover stenting across side branch (SB) subsequent KBD. The jailing configuration SB orifice position were assessed by off-line 3D-OCT core lab. defined cases that achieved both link-free carina distal...
Abstract Aims There were no previous studies comparing aspirin versus P2Y12 inhibitor monotherapy following short dual antiplatelet therapy (DAPT) after complex percutaneous coronary intervention (PCI). Methods and Results We conducted a prespecified subgroup analysis based on PCI in the 1-year results of STOPDAPT-3 trial, which randomly compared 1-month DAPT followed by (aspirin group) to prasugrel clopidogrel (clopidogrel group). The main present study was 30-day landmark analysis....
High bleeding risk (HBR) and acute coronary syndrome (ACS) subtypes are critical in determining cardiovascular event after percutaneous intervention (PCI).
Abstract We experienced a successfully treated case who had 99% stenosis with severe delay of the ostial LAD which bifurcated steeply from LMT. On treating this extreme situation, we used newly developed “reversed guidewire” technique, and two Cypher™ stents were deployed as cullotte‐stent for LMT bifurcation successfully. The technique is considered to be useful method extremely angled bifurcation. © 2008 Wiley‐Liss, Inc.
Various two-stent techniques have been applied to aggressively treat bifurcation lesions as the introduction of drug-eluting stents (DES) and importance angle three-dimensional (3D) structure has come be recognized. Recent 64 multislice computed tomography (MSCT) technology provides accurate information about 3D geometry coronary arteries with reproducibility.The purpose this study is disclose in humans elucidate for crush technique using MSCT.Two hundred nine patients who were suspected...
Abstract Purpose: We examined the importance of prolonged inflation time for optimal sirolimus‐eluting stent (SES) or paclitaxel‐eluting (PES) expansion. Methods: Eighty‐one de novo lesions deployed single SES PES between April 2007 and March 2008 were divided into four groups; group 1: 21 at 20 atm × 60 sec, 2: with 2‐step sec following 3: same as 1, 4: 2. The minimal lumen diameter (MLD) expansion ratio (SER; cross‐ sectional area lesion/balloon cross‐sectional which was calculated...
Side branch (SB) occlusion during bifurcation stenting is a serious complication. This study aimed to predict SB compromise (SBC) using optical coherence tomography (OCT).
The renin-angiotensin system may play a pivotal role in reperfusion ventricular arrhythmias (RVA). purpose of this study was to investigate the association between angiotensin-converting enzyme (ACE) gene polymorphism and RVA patients with acute myocardial infarction (AMI) case - control study. Patients who had undergone successful coronary intervention for AMI were enrolled (n=127, male/female: 97/30, mean age, 62.6 years). incidence continuously monitored by ECG at care unit. severity...
To examine the long-term outcome of stent fracture (SF) and potential predictive factors contributing to in-stent restenosis (ISR) in fractured stent.The SF is thought be a higher risk ISR drug-eluting stent, although does not always develop ISR.The consecutive 1,228 de novo lesions 1,079 patients who underwent sirolimus-eluting stents implantation assessed by 8 months follow-up coronary angiography were retrospectively analyzed.One hundred seventeen SFs (9.5%) identified 100 22 (18.8%)...
Background Stent thrombosis (ST) after drug‐eluting stent (DES) implantation remains a life‐threatening complication. Recurrent ST (RST) is not rare phenomenon, potentially contributing to high mortality the index events. However, little evidence available about incidence, risk factors, and clinical outcomes of definite RST DES thrombosis. Methods Results From REAL‐ST (Retrospective Multicenter Registry After First‐ Second‐ Generation Implantation), this study evaluated 595 patients with...
We aimed to investigate the serial change of side-branch ostial area (SBOA) depended on wire-position before Kissing-balloon inflation (KBI) in single-stent strategy for bifurcation lesions separately left main coronary artery (LMCA) and non-LMCA.Patients who underwent a KBI lesion had OCT images at timing rewiring, post-procedure, 9-month follow-up were extracted from 3D-OCT Bifurcation Registry, which is multicenter-prospective registry patients with percutaneous intervention under...
This article comprised the data related to research 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]. this we reports details about two patterns guide wire (GW) recrossing position after crossover stenting lesion classified with (3D-OCT) (Okamura 2014) [2] follow-up percutaneous intervention(PCI) terms two- (2D) or 3D-OCT guidance. Subgroup...
The jailing strut configuration with link-free and distal guidewire recrossing (LFD) at the side branch orifice (SBO) reduces incomplete stent apposition (ISA) after kissing balloon technique (KBT) in crossover stenting of coronary bifurcation lesions (CBLs). However, data regarding vascular healing KBT are lacking. We investigated 9 months followed by optical coherence tomography (OCT) guidance a prospective multicenter registry.
Nodular calcification is sometimes detected in the native coronary artery. However, it very rare to find a saphenous vein graft (SVG). We herein report case of stable angina pectoris (AP) due nodular calcification. A 75-year-old man who had previously undergone artery bypass grafting was admitted our hospital AP. On angiography, significant stenosis proximal SVG. Based on findings angiography and optical coherence tomography, red thrombus suspected at culprit lesion. also suspected, as there...
