OBJECTIVES: We investigated the safety and efficacy of coronary orbital atherectomy to treat severely calcified lesions prior to stenting based upon age. BACKGROUND: The ORBIT II study reported the safety and efficacy with orbital atherectomy in 443 patients with severely calcified lesions. Elderly patients undergoing percutaneous coronary intervention may be at increased risk for major adverse cardiac events (MACE) and death compared with younger patients. METHODS: Patients were stratified according to age (≥75 year old [174/443, 39...

Stent thrombosis is a major complication of coronary stent and scaffold intervention. While often unanticipated and lethal, its incidence is low making mechanistic examination difficult through clinical investigation alone. Thus, throughout the technological advancement of these devices, experimental models have been indispensable in furthering our understanding of device safety and efficacy. As we refine model systems to gain deeper insight into adverse events, it is equally important that we continue to refine our measurement methods...

One particular complexity of coronary artery is the natural tapering of the vessel with proximal segments having larger caliber and distal tapering as the vessel get smaller. The natural tapering of a coronary artery often leads to proximal incomplete stent apposition (ISA). ISA alters coronary hemodynamics and creates pathological path to develop complications such as in-stent restenosis, and more worryingly, stent thrombosis. By employing state-of-the-art computer-aided design software, generic stent hoops were virtually deployed in an idealized tapered coronary artery with decreasing malapposition distance...

BACKGROUND: There are limited data regarding the prognostic impact of angiographic complete revascularization (CR) in patients with chronic kidney disease (CKD). We sought to investigate the differential prognostic impact of angiographic CR over incomplete revascularization (IR), according to the presence of CKD in the drug-eluting stent era. METHODS AND RESULTS: Between 2003 and 2011 at Samsung Medical Center, consecutive patients with multivessel disease were stratified by the presence of CKD (estimated glomerular filtration rate <60 mL/min per 1...

Drug-eluting stents revolutionized the treatment of coronary artery disease with vastly improved outcomes compared with bare metal stents. As stent technology has evolved, a wide variety of antiproliferative drugs have been developed to prevent stent restenosis and stent thrombosis. The Resolute stent system (Medtronic, CA, USA) elutes zotarolimus from a multipolymer blend to prevent early and late stent-related complications. The Resolute stents have evolved from the initial Resolute stent, to the Resolute Integrity™ and most recently, the Resolute Onyx™...

BACKGROUND AND RATIONALE: Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor reduces thrombotic events in patients undergoing percutaneous coronary intervention (PCI), but these benefits come at the expense of increased risk of bleeding when compared with aspirin monotherapy. It is unclear whether P2Y12 inhibitor monotherapy might maintain anti-ischemic efficacy while reducing the bleeding risk compared with DAPT after implantation of the current generation of drug-eluting stents (DES)...

BACKGROUND: The CPORT-E trial showed the noninferiority of nonprimary percutaneous coronary intervention (PCI) at hospitals without cardiac surgery on-site (SoS) compared with hospitals with SoS for 6-week mortality and 9-month major adverse cardiac events (MACE). However, target vessel revascularization (TVR) was increased at non-SoS hospitals. Therefore, we aimed to determine the consistency of the CPORT-E trial findings across the spectrum of enrolled patients. METHODS: Post hoc subgroup analyses of 6-week mortality and 9-month MACE, defined as the composite of death, Q-wave myocardial infarction, or TVR, were performed...

BACKGROUND: There is a paucity of data from large contemporary cohorts of patients with in-stent restenosis (ISR) treated with drug-eluting stents (DESs), and no studies have examined the impact of high platelet reactivity (HPR) on the occurrence of ischemic events after ISR percutaneous coronary intervention (PCI) with DESs. We sought to report outcomes after PCI of ISR lesions and its association with HPR. METHODS: Patients in the prospective, multicenter ADAPT-DES study were stratified according to whether they had ISR versus non-ISR PCI...

BACKGROUND: We compared efficacy and safety of short- (3 or 6 months) versus long-term (≥12 months) dual antiplatelet therapy (DAPT) after drug-eluting stent (DES) implantation, according to the presence of chronic kidney disease (CKD). METHODS: Patient-level pooled analysis was performed with 7242 patients (87.2% with 2nd generation DES) from 5 randomized controlled trials. RESULTS: In both CKD (1273 patients) and non-CKD (5969 patients) population, the rates of patient-oriented composite outcomes at 1-year (POCO, all-cause death, any myocardial infarction [MI], stroke and TIMI major bleeding) were not different between the short- and long-term DAPT (hazard ratio [HR] 1...

BACKGROUND: Most intra-coronary stents in use are made of 316 L stainless steel, which contains nickel, chromate and molybdenum. Whether inflammatory and allergic reactions to metals contribute to in-stent restenosis is still a matter of debate. AIM: The aim of this study was to ascertain the relationship between metal allergy and the occurrence of in-stent restenosis. METHODS: Ninety-nine adult patients who underwent two cardiac catheterisations, up to two years apart, were included in the study...

Drug eluting stents (DES) have been increasingly being used for treatment of coronary artery disease (CAD) and have been shown to be very effective in prevention of primary in-stent restenosis (ISR). However DES have been increasingly associated with acute to subacute risk of stent fractures (SF). There is also a paucity of data about different management strategies for SF, especially in the long term. We present a case of recurrent ISR in an area of previous acute SF at the touchdown of saphenous venous graft (SVG) to first diagonal artery (D1)...

A 63-year-old man presented with an out-of-hospital cardiac arrest. The coronary angiogram with intravascular imaging was performed and showed a mid-left anterior descending artery atherosclerotic cap rupture with thrombus burden treated with drug-eluting stent (DES) implantation. During the hospitalisation in the intensive care unit, the patient experienced recurrent ventricular fibrillations and asystole with transient ST-segment elevation in the inferior leads with normal coronary angiography. A methylergonovine provocative test was therefore performed and showed an occlusive right coronary artery (RCA) spasm...

We present a case of an 80-year-old Turkish female patient with diabetes who suffered an acute myocardial infarction (AMI) and underwent percutaneous coronary balloon angioplasty (PTCA)/stenting. Due to new ischaemic episodes, a second PTCA/stenting had to be preformed 6 days later, which revealed a partial restent thrombosis. This case report raises several important issues. First, language problems are an important barrier for safety and quality in healthcare. Second, gender, ethnicity and age differences in patients with AMI need to be considered in order to eliminate inequities in clinical practice...
