BACKGROUND: Coronary artery bypass grafting (CABG) is the standard of care for treating left main coronary lesions. However, recently published randomized controlled trials (RCT) have shown conflicting results. We sought to compare clinical outcomes of percutaneous coronary intervention (PCI) with drug-eluting stent placement to CABG using a meta-analysis of randomized controlled trials. METHODS: A systemic search of Pubmed, Scopus, Cochrane library, and Clinicaltrials...

Clinical outcome is generally poor when stents are implanted at right coronary artery ostial lesion (RCAos). We compared the clinical outcome between the first-generation drug-eluting stent (first DES) and second-generation drug-eluting stent (second DES) used for RCAos. Consecutive 88 patients who underwent percutaneous coronary interventions of de novo RCAos using the first DES (33 patients) or second DES (55 patients) were analyzed. The incidence of major adverse cardiac events (MACE) defined as the composite of cardiac death, myocardial infarction attributed to right coronary artery, and target lesion revascularization within 2...

BACKGROUND: Smoking has been shown to reduce health-related quality of life (HRQOL) in patients with coronary artery disease (CAD) undergoing percutanous coronary intervention (PCI) either by means of balloon angioplasty or with the use of bare-metal stents (BMS). Drug-eluting stents (DES) have now been widely used and are related to substantial reduction of restenosis and significantly improved HRQOL compared with BMS. This study aimed to evaluate the effects of smoking on HRQOL in patients after PCI in DES era...

This case report describes a successful percutaneous coronary intervention (PCI) of a severely calcified aorto-ostial chronic total occlusion (CTO) of the right coronary artery (RCA). The lesion was treated by a retrograde approach implementing long spiral subintimal wire tracking and final coronary stenting creating a subintimal neo-luminal helix around the natively occluded RCA. After 6 months of follow-up valuable angiographic results were proven.

BACKGROUND: Kissing-balloon technique (KBT) is commonly performed during percutaneous coronary intervention of distal unprotected left main coronary artery (ULM) aiming at obtaining optimal opening of the side branch (left circumflex artery; LCX) ostium. Nonetheless, detailed evaluation of vascular response to stents in LCX ostium is lacking. We therefore evaluated the vascular response to different drug-eluting stents (DES) in ostial LCX after ULM by means of optical coherence tomography (OCT)...

BACKGROUND: Percutaneous coronary intervention (PCI) is effective therapy for significant atherosclerotic coronary artery disease. Despite medical and technological advances in PCI, periprocedural myocardial infarction (PMI) remains a common complication. The frequency and factors associated with PMI have been well investigated in the developed world, yet there is a paucity of data from the developing world, especially Sub-Saharan Africa. METHODS: We prospectively enrolled 153 adult patients undergoing PCI at the Charlotte Maxeke Johannesburg Academic Hospital from the 1st of February 2014 to 31st October 2014...

INTRODUCTION: Patients with diabetes and coronary artery disease remain at high risk for adverse cardiovascular events after percutaneous coronary intervention. The efficacy and safety of the various drug-eluting stents (DES) in patients with diabetes is unclear. METHODS: Randomized controlled trials comparing first-generation DES [paclitaxel-eluting stents (PES) and sirolimus-eluting stents (SES)] with everolimus-eluting stents (EES) and zotarolimus-eluting stents (ZES) in diabetic patients were systematically searched...

REVIEW
Aparna Dalal
Patients listed for organ transplant frequently have severe coronary artery disease (CAD), which may be treated with drug eluting stents (DES). Everolimus and zotarolimus eluting stents are commonly used. Newer generation biolimus and novolimus eluting biodegradable stents are becoming increasingly popular. Patients undergoing transplant surgery soon after the placement of DES are at increased risk of stent thrombosis (ST) in the perioperative period. Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor such as clopidogrel, prasugrel and ticagrelor is instated post stenting to decrease the incident of ST...

BACKGROUND: In-stent restenosis occurs in 10-30% of patients following bare metal stent (BMS) implantation and has various risk factors. Mannose-binding lectin (MBL) is known to have effect on the progression of atherosclerosis. Single nucleotide polymorphisms (SNP) of the MBL2 gene intron 1 (codon 52, 54, 57) are known to modulate the bioavailability of the MBL protein. Our aim was to identify the association of these polymorphisms of the MBL gene in the occurrence of in-stent restenosis after coronary artery bare metal stent implantation...

Orbital atherectomy has been developed as a method to modify calcified plaque in the peripheral vasculature, with extensive experience and data supporting its use in infrainguinal peripheral arterial disease. However, calcific atherosclerotic disease occurs in other vascular beds and may benefit from the application of this technology. In this case report, we describe the first reported use of orbital atherectomy in a renal artery. A 55-year-old male with severe drug-refractory hypertension was found to have renal artery stenosis, with severe calcification of the right renal artery...

BACKGROUND: Percutaneous coronary intervention (PCI) of lesions with coronary arterial calcification (CAC) is common and has been historically associated with an increased risk of adverse events. Whether the association between target lesion calcification (CAC) and outcomes differ across drug-eluting stent generation or between patients with high vs. low residual platelet reactivity (PR) remains unknown. We assessed the association of CAC with adverse ischemic and bleeding events among patients undergoing contemporary PCI with drug-eluting stents (DES)...
