INTRODUCTION: Prior studies of ULM STEMI have been confined to small cohorts. Recent registry data with larger patient cohorts have shown contrasting results. We aim to study the outcomes of patients with unprotected left main (ULM) ST-elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI). METHODS: The Asia-pacific left main ST-Elevation Registry (ASTER) is a multicenter retrospective registry involving 4 sites in Singapore, South Korea, and the United States...

BACKGROUND: There are limited data on the frequency of and factors associated with quantitative coronary angiography (QCA)-defined longitudinal stent deformation (LSD) in various contemporary drug-eluting stents platforms. This study sought to evaluate the predictors of LSD and its long-term clinical implication. METHODS AND RESULTS: A patient-level pooled analysis was performed with 7350 lesions in 5871 patients treated with platinum-chromium-based everolimus-eluting stent (Promus Element), cobalt-chromium-based everolimus-eluting stent (Promus/Xience V), or cobalt-chromium-based zotarolimus-eluting stent (Endeavor Resolute)...

Treatment of chronic mesenteric ischemia has evolved over the last two decades. Endovascular therapy is now the treatment of choice for patients with lesions amenable to such an approach. Open revascularization remains the standard of care but is frequently being reserved for lesions containing intraluminal thrombus or severe calcification. In most cases, celiac axis (CA) stenting is not needed since revascularization of the superior mesenteric artery (SMA) alone results in symptomatic resolution. This report describes a case of a patient with chronic mesenteric ischemia and diffuse gastric ulcers found to have a common origin of the SMA and CA that was treated endovascularly using a bifurcated stent technique...

Intravascular ultrasound (IVUS) is mainly used in PCI to treat complex lesions, such as left main bifurcation, chronic total occlusion and calcified lesions. Although IVUS yields useful information such as the presence of napkin-ring calcification, the role of IVUS in rotational atherectomy (RA) is not fully appreciated. Recently, since the deliverability and crossability of IVUS catheters have improved, IVUS should be attempted before RA. Even if the IVUS catheter cannot cross the lesion, IVUS provides information just proximal to the target lesion, which would be useful in the selection of the appropriate guidewire and burr size...

BACKGROUND: Macrophages play a pivotal role in atherosclerotic plaque development. Recent evidence has suggested the glucagon-like peptide-1 receptor (GLP-1R) agonist, liraglutide, can attenuate pro-inflammatory responses in macrophages. We hypothesized that liraglutide could limit atherosclerosis progression in vivo via modulation of the inflammatory response. METHODS: Human THP-1 macrophages and bone marrow-derived macrophages, from both wild-type C57BL/6 (WT) and apolipoprotein E null mice (ApoE(-/-)) were used to investigate the effect of liraglutide on the inflammatory response in vitro...

BACKGROUND: Hypotension (HT) is well recognized to frequently occur during and after carotid artery stenting (CAS), which sometimes causes postoperative complications such as stroke or myocardial infarction. This study aimed to examine the risk factors associated with HT after CAS based on the hypothesis that overlapped stenting may affect postoperative HT. METHODS: A total of 106 lesions in 95 patients with carotid artery stenosis who underwent CAS were reviewed...

BACKGROUND: Computational fluid dynamics (CFD) allows noninvasive fractional flow (FF) computation in intracranial arterial stenosis. Removal of small artery branches is necessary in CFD simulation. The consequent effects on FF value needs to be judged. METHODS: An idealized vascular model was built with 70% focal luminal stenosis. A branch with one third or one half of the radius of the parent vessel was added at a distance of 5, 10, 15 and 20 mm to the lesion...

BACKGROUND: Provisional stenting (PS) is the most common technique used to treat distal left main (LM) bifurcation lesions in patients with unprotected LM coronary artery disease undergoing percutaneous coronary intervention. The double kissing (DK) crush planned 2-stent technique has been shown to improve clinical outcomes in non-LM bifurcations compared with PS, and in LM bifurcations compared with culotte stenting, but has never been compared with PS in LM bifurcation lesions. OBJECTIVES: The authors sought to determine whether a planned DK crush 2-stent technique is superior to PS for patients with true distal LM bifurcation lesions...

OBJECTIVE: To evaluate the feasibility of a novel technique for achieving distal SB access and improve strut apposition during provisional stenting. BACKGROUND: While distal rewiring and stent expansion toward the side branch (SB) are associated with better results during provisional stenting of coronary artery bifurcation lesions, these techniques are technically challenging and often leave unopposed struts near the carina. METHODS: The "Jail Escape Technique" (JET) is performed by passing the proximal tip of the SB wire between the main vessel (MV) stent struts and balloon before implantation, allowing the MV stent to push the SB wire against the distal part of the carina...

Crossover stenting of femoral bifurcation raises the concern of jeopardizing the deep femoral artery (DFA) entry, thereby increasing future risk of limb-threatening ischemia and amputation. This retrospective multicenter study compared clinical outcomes of crossover stenting and non-crossover stenting for ostial superficial femoral artery (SFA) lesions. We reviewed 125 limbs in 103 patients with successful stent implantation for ostial SFA lesions and allocated them to two groups, based on whether the stent crossed over the DFA orifice (CO, n = 54) or not (NC, n = 71)...

BACKGROUND: Although bifurcation percutaneous coronary intervention (PCI) is associated with lower procedural success rates and higher risk of complications, there are little data regarding outcomes after successful bifurcation PCI with contemporary stents and techniques. Whether residual platelet reactivity (PR) affects outcomes differently after bifurcation versus non-bifurcation PCI is also unknown. We studied the association between bifurcation PCI, PR, and clinical outcomes among patients undergoing successful PCI with drug-eluting stents...

Despite the improvement of outcomes after the introduction of bare metal and drug eluting stents for the treatment of CAD, certain type of patients have still an increased risk of stent failure. An alternative is represented by drug-eluting balloons (DEB). This innovation could give potential benefits in particular for the in-stent restenosis (ISR) and the de-novo lesions. In the first setting DEB have shown results superior to those with plain-balloon angioplasty and similar to those with first generation DES...
