Blunt subclavian artery injuries are rare and are associated with high morbidity and mortality. Several case reports have suggested that endovascular repair is safe with short operative times and minimal blood loss. We report a case of a 20-year-old male patient involved in a high speed motor vehicle collision that resulted in partial transection of left subclavian artery with complete luminal thrombosis. Patient also had a left main-stem bronchus avulsion along with major intra-abdominal injuries and multiple spine and long bone fractures...

BACKGROUND: Current guidelines suggest that coronary artery bypass grafting (CABG) should be the preferred revascularization method for unprotected left main coronary artery stenosis. In light of evidence from recent randomized trials, we assessed whether percutaneous coronary intervention (PCI) using drug-eluting stents is as safe and effective as CABG for the treatment of unprotected left main coronary artery disease. METHODS AND RESULTS: Digital databases and manual searches were performed for randomized trials comparing PCI and CABG for unprotected left main coronary artery stenosis...

We assessed long-term outcomes after left main coronary artery (LMCA) stenting based on lesion types and stenting strategies. In the Assessing Optimal percutaneous coronary Intervention for Left Main Coronary Artery stenting registry, we evaluated 1,607 consecutive patients undergoing stent implantation for unprotected LMCA lesions (bifurcation lesions: n = 1318 and nonbifurcation lesions: n = 289). Among the bifurcation lesions, 1,281 lesions were treated with stenting across the bifurcation (bifurcation 1-stent strategy: n = 999 or bifurcation 2-stent strategy: n = 282)...

BACKGROUND: Drug-eluting stent (DES) -induced coronary vasospasm is a well known phenomenon after stent implantation; however, the extent of this risk is still unknown. We report a case in which DES-induced severe coronary vasospasm was clinically suspected as a cause of subacute stent thrombosis (ST). CASE PRESENTATION: A 67-year-old man came to our hospital due to chest pain with mild exercise. He was diagnosed with effort angina by coronary angiography and underwent DES implantation in the mid-left ascending artery (LAD) after the administration of dual anti-platelet therapy...

A 76-year-old man with aplastic anemia presented with recurrent acute myocardial infarction (AMI) with heart failure. After the initial appearance of AMI approximately 2 months earlier, he had received conservative treatment/transfusion alone because of severe thrombocytopenia and anemia (platelet 11 × 10(3)/μL, hemoglobin 6.4 g/dL). Refractory heart failure persisted despite repeated conservative treatment/transfusion for the second AMI, and therefore, we performed transradial coronary angiography and left main crossover stenting with a bare metal stent...

BACKGROUND: There are only little data available on the comparison of clinical outcomes between a 1-stent strategy (1-SS) and a 2-stent strategy (2-SS) for percutaneous coronary intervention in unprotected distal left main disease. METHODS AND RESULTS: Between April 2005 and August 2011, we recruited 937 consecutive unprotected distal left main patients treated with drug-eluting stents (1-SS, 608 patients; 2-SS, 329 patients). Major adverse cardiovascular events were defined as all-cause death, myocardial infarction, or target lesion revascularization (TLR) during the median follow-up period of 1592 days...

BACKGROUND: Percutaneous coronary intervention (PCI) is most commonly guided by angiography alone. Intravascular ultrasound (IVUS) guidance has been shown to reduce major adverse cardiovascular events (MACE) after PCI, principally by resulting in a larger postprocedure lumen than with angiographic guidance. Optical coherence tomography (OCT) provides higher resolution imaging than does IVUS, although findings from some studies suggest that it might lead to smaller luminal diameters after stent implantation...

INTRODUCTION: Cardiac inflammatory myofibroblastic tumor is a rare tumor that can cause potentially fatal outcomes. CASE PRESENTATION: We describe a case where the tumor originated on the mitral valve and extended through the left ventricular outflow tract and aortic valve and into the left main artery obstructing it. Due to the hemodynamic instability of the patient, we proceeded for cardiac catheterization with the intention to aspirate the mass but were forced to do percutaneous intervention to stabilize the patient and bridge him to surgery...

Background Patients with obstructive left main coronary artery disease are usually treated with coronary-artery bypass grafting (CABG). Randomized trials have suggested that drug-eluting stents may be an acceptable alternative to CABG in selected patients with left main coronary disease. Methods We randomly assigned 1905 eligible patients with left main coronary artery disease of low or intermediate anatomical complexity to undergo either percutaneous coronary intervention (PCI) with fluoropolymer-based cobalt-chromium everolimus-eluting stents (PCI group, 948 patients) or CABG (CABG group, 957 patients)...

BACKGROUND: The most common complication of coronary artery perforation, a rare complication of percutaneous coronary intervention (PCI), is hemopericardium with cardiac tamponade. However, localized extra-coronary bleeding can lead to epicardial hematoma, which is a rare phenomenon. We report the case of an unusual delayed presentation of post-PCI hematoma with unrecognized guidewire perforation. CASE PRESENTATION: A 70-year-old man with idiopathic thrombocytopenic purpura (ITP) and a history of coronary artery bypass grafting (CABG) underwent PCI...

Aim. Diabetes mellitus (DM) is a major risk factor for cardiovascular disease. The implications of a diagnosis of DM are as severe as the diagnosis of coronary artery disease. For many patients with complex coronary artery disease, optimal revascularization strategy selection and optimal medical therapy are equally important. In this study, we compared the hemodynamic results of different stenting techniques for Medina 0,1,0 left main bifurcation lesions. Methods. We use idealized left main bifurcation models and computational fluid dynamics analysis to evaluate hemodynamic parameters which are known to affect the risk of restenosis and thrombosis at stented bifurcation...
