Mamary artery

Ahmed Al-Mamary, Filippo Zilio, Massimo Napodano
Optimal management of multivessel coronary artery disease can be complex. We report a 67-year-old male patient who was admitted to the Padua University Hospital, Padua, Italy, in 2014 with a non-ST-elevation myocardial infarction. Coronary angiography showed diffuse multiple sub-occlusive lesions of the proximal and distal left coronary vessels involving a long segment of the vessel. On intravascular ultrasonography (IVUS), the left main artery was moderately diseased with critically stenotic and calcified branch ostia...

This study aims to develop and validate a new angiographic risk score to predict the risk of distal embolization (DE) during primary percutaneous coronary intervention (p-PCI) for ST-elevation myocardial infarction. Study included data from 1,200 patients who underwent p-PCI. The cohort was randomly split into a derivation cohort (n = 814) and a validation cohort (n = 386). Logistic regression was used to examine the relation between risk factors and the occurrence of DE. To each covariate in the model was assigned an integer score based on the regression coefficients...

BACKGROUND: Recent studies have described neo-atherosclerosis, developing inside the stent, as cause of very late stent thrombosis. CASE REPORT: A 59-year-old man, with family history of coronary artery disease, presented to our Department because of anterior ST-segment elevation myocardial infarction. Two years before he had underwent percutaneous coronary intervention with multiple drug-eluting stents (DES) implantation on proximal-mid left anterior descending artery (LAD), and mid-right coronary artery (RCA), respectively...

BACKGROUND: Coronary stent fracture is an under-recognized event but one that has been reported frequently in the drug-eluting stent era. Most reported cases of stent fracture occurred within days to two years after implantation, and are related to stent thrombosis and restenosis. CASE REPORT: Presentation of a 69-year-old male with a history of arterial hypertension and previous percutaneous coronary intervention (PCI), and with implantation of three overlapping drug-eluting stents (DES) on proximal-to-middle left anterior descending artery (LAD)...

Large thrombus burden (LTB) lesions in the context of primary percutaneous coronary intervention (p-PCI) have been related to unsuccessful angiographic reperfusion and unfavorable clinical outcomes. However, the hazard of LTB treatment on myocardial damage has not been evaluated. We investigated the impact of LTB on myocardial damage using contrast-enhanced cardiac magnetic resonance (CE-CMR) in the setting of p-PCI. In 327 patients, who underwent p-PCI without thrombus aspiration within 12 hours from symptom onset, we prospectively assessed the impact of LTB on infarct size and microvascular damage using CE-CMR...

OBJECTIVE: Our study aimed to support the viability of the concept of Ipsilateral Dual Kidney Transplantation (DKT) by presenting our initial experience and proposing a review of the literature in this subject. METHODS: Fifteen ipsilateral DKT were performed at Nice University Hospital between August 2010 and March 2012. We have described our skin incision preferences, the vascular anastomoses, and the uretero-vesical reimplantation. We have analyzed the operative duration, the cold ischemia time (CIT) of both transplants, the blood transfusion volume, the intraoperative and postoperative complications, the time to diuresis recovery, the hospital stay, and the kinetics of the creatinine clearance until the third postoperative month...

INTRODUCTION: Techniques of coronary artery revascularisation on the beating heart have evolved with an attempt to reduce the potential deleterious effects of extracorporeal circulation. It is of particular value in those with a calcified or atheromatous ascending aorta. Total arterial revascularisation is ideal. CASE REPORT: We describe a case of 66 year-old male patient, previously suffered mild cerebrovascular incident, schedueled for myocardial revascularisation of double coronary disease with Left main stenosis...

BACKGROUND: Exacerbations of chronic obstructive pulmonary disease (COPD) are associated with accelerated loss of lung function and death. Identification of patients at risk for these events, particularly those requiring hospitalization, is of major importance. Severe pulmonary hypertension is an important complication of advanced COPD and predicts acute exacerbations, though pulmonary vascular abnormalities also occur early in the course of the disease. We hypothesized that a computed tomographic (CT) metric of pulmonary vascular disease (pulmonary artery enlargement, as determined by a ratio of the diameter of the pulmonary artery to the diameter of the aorta [PA:A ratio] of >1) would be associated with severe COPD exacerbations...

An NADPH-oxidase complex containing at least two protein components (gp91-phox and p22-phox) and a unique low redox potential (-245 mV) cytochrome b-245 is the source of superoxide generated for bacterial killing in neutrophils and has been suggested as the oxygen sensor in the carotid body. In pure cultures of smooth muscle cells from calf small pulmonary arteries (300 microns diameter) the presence of the 91 kD protein specific to this cytochrome was demonstrated by Western blot analysis with monoclonal antibody 48...
