Background: The use of Y-shaped aorto-coronary saphenous vein grafts is most commonly driven by efforts to replace the poor quality (length) of the vein grafts or to minimise manipulation of the atheromatous ascending aorta (Jarvis [1]). We found only a few case reports describing PCI of bifurcation lesions in vein grafts in the available scientific literature (Karalis [2], Prosser and Bailey [...

Background: To evaluate the association between pre/post-procedural high sensitive C-reactive protein (hs-CRP) level and hs-CRP difference, and the risk of major adverse cardiovascular events (MACE) or new diffusion-weighted MRI lesions after carotid angioplasty and stenting (CAS). Methods: In this study, conducted in 2016 in Shiraz (Iran), patients who underwent diagnostic angiography and CAS...

P ercutaneous coronary intervention (PCI) to the left main coronary artery (LM) presents important technical challenges that are both lesion and site specific. Available technology has improved and so has our understanding of how to optimise short and long term outcome, but nevertheless intervention to this area demands special consideration. Critical analysis of the literature can only be perf...

BACKGROUND/AIMS To compare the clinical outcomes of 'on-label' and 'off-label' drug-eluting stents (DESs) over a 5-year follow-up period. METHODS A total of 929 patients that underwent percutaneous coronary intervention with DESs were enrolled. Patients were divided into two groups according to on-label (n = 449) and off-label (n = 480) indications. Off-label use was defined as implantation o...

OBJECTIVES To examine by retrospective analysis of data from the FLEXI-CUT monocentre registry whether atherectomy can effectively simplify complex stent implantation in ostial bifurcation lesions by reducing the procedure to stenting of the left anterior descending (LAD) or left circumflex (LCX) artery ostium alone. PATIENTS AND METHODS All patients who had been enrolled in the prospective F...

AIM The combined use of stents and abciximab in percutaneous coronary intervention has been evaluated in the EPISTENT trial. However, the clinical and economic findings in trials are not necessarily generalisable to a general population setting. We conducted a study in daily clinical practice comparing stented and non-stented patients undergoing coronary angioplasty with abciximab administratio...

of the angioplasty segment between the concentric and eccentric lesion subgroups was not significant (analysis of variance) at any time after PTCA. The degree of vasoconstriction observed in the angioplasty segment of both the concentric and eccentric lesion subgroups were significantly greater than that of the control segment at 15 and 30 minutes after PTCA (p CO.01 and <0.005, respectively). ...

OBJECTIVE Percutaneous coronary intervention for coronary bifurcation lesion is very challenging, especially for true bifurcation lesions. Although the jailed semi-inflated balloon technique is one of the established methods for treatment of coronary bifurcation lesions, little is known regarding the configuration of the side branch orifice after stent implantation using this technique. METHO...

OBJECTIVES This study aimed to investigate the roles of intracoronary derived coronary flow velocity reserve (CFVR) and myocardial perfusion scintigraphy (single photon emission computed tomography, or SPECT) for management of an intermediate lesion in patients with multivessel coronary artery disease. BACKGROUND Evaluation of the functional significance of intermediate coronary narrowings (4...

OBJECTIVES To investigate whether intravascular ultrasound (IVUS) guided percutaneous coronary intervention (PCI) could improve clinical outcomes compared with angiography-guided PCI in the treatment of unprotected left main coronary artery stenosis (ULMCA) in the elderly. METHODS This controlled study was carried out between October 2009 and September 2012, in Qinhuangdao First Hospital, Heb...
