OBJECTIVE: Motion artifact can reduce the diagnostic accuracy of coronary CT angiography (CCTA) for coronary artery disease (CAD). The purpose of this study was to compare the diagnostic performance of an algorithm dedicated to correcting coronary motion artifact with the performance of standard reconstruction methods in a prospective international multicenter study. SUBJECTS AND METHODS: Patients referred for clinically indicated invasive coronary angiography (ICA) for suspected CAD prospectively underwent an investigational CCTA examination free from heart rate-lowering medications before they underwent ICA...

BACKGROUND: Syntax score (SS), which is an angiographic tool used in grading the complexity of coronary artery disease (CAD), has prognostic importance in coronary artery disease (CAD) and provides important information regarding selection of revascularization strategy. C-reactive protein (CRP) and albumin are indicators of inflammation, and high levels of them are associated with high SS. We aimed to investigate whether baseline CRP to albumin ratio C-Reactive Protein/Albumin Ratio (CAR), an easily available and novel inflammatory marker, is associated with SS...

PURPOSE: Myocardial bridges (MB) have traditionally been considered a benign condition, but recent studies have demonstrated that the clinical complications can be dangerous. The transluminal attenuation gradient (TAG) obtained from coronary computed tomography angiography (CCTA) data (Retrospective ECG-triggered method) has been used in detecting significant stenosis in coronary artery caused by atherosclerosis. Contrast opacification difference (COD) was the parameters calculated as the change between attenuation of mural artery and the median attenuation of presumptive vessel segment; it was evaluated along with TAGstandardized (TAGs) and MB length for predicting MB with systolic compression (MB-SC) in patients diagnosed as MB in left anterior descending coronary artery (LAD) by CCTA or invasive coronary angiograph (ICA)...

OBJECTIVES: Old-generation drug-eluting coronary stents (o-DES) have despite being safe and effective been associated with an increased propensity of late stent thrombosis (ST). We evaluated ST rates in o-DES, new-generation DES (n-DES) and bare metal stents (BMS) the first year (< 1 year) and beyond 1 year (> 1 year). METHODS: We evaluated all implantations with BMS, o-DES (Cordis Cypher, Boston Scientific Taxus Liberté and Medtronic Endeavor) and n-DES in the Swedish coronary angiography and angioplasty registry (SCAAR) between 1 January 2007 and 8 January 2014 (n = 207 291)...

BACKGROUND: Cardiovascular disease (CVD) is the major cause of mortality worldwide. Coronary artery disease (CAD) contributes to half of mortalities caused by CVD. The mainstay of management of CAD is medical therapy and revascularisation. Revascularisation can be achieved via coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). Peripheral arteries, such as the femoral or radial artery, provide the access to the coronary arteries to perform diagnostic or therapeutic (or both) procedures...

: Vascular response to exogenously administered nitroglycerine, an index of endothelium-independent vasodilation, has been used as a control test for the assessment of endothelium-dependent vasodilation (endothelial function) in humans. However, evidence has been accumulating that not only endothelium-dependent vasodilation but also endothelium-independent vasodilation per se is impaired in individuals with cardiovascular risk factors and cardiovascular disease. Impaired endothelium-independent vasodilation is associated with structural vascular alterations and alterations in vascular smooth muscle cells...

Coronary angiography and percutaneous coronary artery intervention are important tools for the diagnosis and treatment of coronary artery disease. Nevertheless, despite both technical and pharmacological advances, bleeding and vascular complications remain problematic. With recent trials supporting the safety and decreased bleeding risk associated with the radial approach, radial access has become more popular, and conferences providing instruction on this technique are often standing room only. Herein, a case in which coronary angiography was performed by punching through the radial artery snuff box (fovea radialis) is described...

Kounis syndrome is defined as the clinical development of acute coronary syndrome caused by the activation of inflammatory cells due to an allergy, hypersensitivity, anaphylaxis, or anaphylactic reaction. Corticosteroids that are used in the treatment of many inflammatory conditions may paradoxically cause allergic reactions and even anaphylaxis. This article is a description of the case of a 52-yearold female patient who had a non-ST elevation myocardial infarction after the administration of triamcinolone that was relieved with antihistaminic treatment...

Pulmonary atresia (PA) and ventricular septal defect (VSD) can occur in a variety of ways, from simple valve atresia to a condition in which circulation to the pulmonary bed occurs through collateral arteries separated from the aorta and there are no real pulmonary arteries, or they are present but hypoplastic. The size of the pulmonary arteries and concomitant complex cardiac lesions are important in making decisions about treatment and correctional alternatives. While complete correction surgeries in the style of a correction of tetralogy of Fallot are performed in simpler cases, many very invasive procedures are also performed and the resulting quality of life is very variable...

BACKGROUND: Therapeutic variability not explained by patient clinical characteristics is a potential source of avoidable morbidity and mortality. We aimed to explore regional variability in the management and mortality of patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS). METHODS AND RESULTS: 11,931 NSTE-ACS hospital survivors enrolled in two prospective registries: EPICOR [5625 patients, 555 hospitals, 20 countries in Europe (E) and Latin America (LA), September 2010-March 2011] and EPICOR Asia (6306 patients, 218 hospitals, 8 countries, June 2011-May 2012) were compared among eight pre-defined regions: Northern E (NE), Southern E (SE), Eastern E (EE); Latin America (LA); China (CN), India (IN), South-East Asia (SA), and South Korea, Hong Kong and Singapore (KS)...

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a common coronary artery anomaly associated with high mortality and may lead to sudden death if left unrecognized and untreated. This report describes an 8-year-old female who had cardiac murmur but with no clinical symptoms. Electrocardiogram (ECG) was normal, but echocardiography made the diagnosis of ALCAPA. Digital subtraction angiography (DSA) with cardiac catheterization angiography (CAG) confirmed the diagnosis, and finally, the patient received surgery...

Background: Percutaneous coronary intervention (PCI) had become the major therapeutic procedure for coronary artery disease (CAD), but the high rate of in-stent restenosis (ISR) still remained an unsolved clinical problem in clinical practice. Increasing evidences suggested that diabetes mellitus (DM) was a major risk factor for ISR, but the risk predictors of ISR in CAD patients with DM had not been well characterized. The aim of this study was to investigate the clinical and angiographic characteristic predictors significantly associated with the occurrence of ISR in diabetic patients following coronary stenting with drug-eluting stent (DES)...

In patients with stable coronary artery disease, percutaneous coronary intervention is associated with improved outcomes if the lesion is deemed significant by invasive functional assessment using fractional flow reserve. Recent studies have shown that a revascularization strategy using instantaneous wave-free ratio is noninferior to fractional flow reserve in patients with intermediate-grade stenoses. The decision to perform coronary artery bypass grafting surgery is usually based on anatomic assessment of stenosis severity by coronary angiography...

We present a case of a 54-year-old male patient who was admitted to our Emergency Department (ED) with localized epigastric pain. Inflammation markers, ultrasound, and CT scan were inconsistent with an initial diagnosis of cholecystitis. However, there was additional evidence of cholecystolithiasis. The ECG showed new anterior biphasic T waves typical for a Wellens' type A ECG. Additionally, the patient had an intermittent left bundle branch block (LBBB). The diagnostic challenges in differentiating possible diagnoses will be described, to which in this case, were either acute cholecystitis or acute coronary syndrome (ACS)...

BACKGROUND: Reduced forced expiratory volume in 1 second percentage (FEV1%) predicted is closely related to cardiovascular mortality. However, evidence regarding the correlation between FEV1% predicted and the severity of coronary atherosclerosis observed on coronary angiography is still limited. We aimed to explore whether a decline in FEV1% predicted was associated with diffuse coronary atherosclerosis in hospitalized patients. METHODS: A cross-sectional study enrolling hospitalized patients with cardiovascular symptoms undergoing both coronary angiography and lung function testing was conducted...

During transcatheter pulmonary valve placement, coronary compression observed during simultaneous right ventricular outflow tract angioplasty and coronary angiography typically contraindicates valve implantation. We present a unique patient with tetralogy of Fallot who underwent successful transcatheter Melody valve placement despite coronary compression observed during right ventricular outflow tract balloon angioplasty.
