BACKGROUND: Although transradial percutaneous coronary intervention (TR-PCI) is widely used in clinical practice, guidewire-related complications are an important cause of transradial approach failure. We investigated the prognostic value of the 260-cm Amplatz Super Stiff guidewire for reducing the complication rate during TR-PCI. METHODS: Five hundred patients with positive Allen's test results were divided into 3 groups according to the type of angiography guidewire: group A, 150-cm Emerald guidewire standard J-tip (n = 160); group B, 150-cm Radifocus guidewire M (n = 176); and group C, exchangeable 260-cm Amplatz Super Stiff guidewire after placement of a 150-cm Radifocus guidewire M (n = 164)...

BACKGROUND AND AIM: Nowadays there is a strong necessity in identifying patients who may be exposed to the risk for future cardiovascular events like progressive atherosclerotic disease. Biomarkers are valuable tools for this purpose. Coronary artery calcification (CAC) is utilized as an important tool for the global risk assessment of cardiovascular events in individuals with intermediate risk. Decorin (DCN) is a small leucine-rich proteoglycan that induces calcification of arterial smooth muscle cell and localizes to mineral deposition in human atherosclerotic plaque...

Congenital atresia of the left main coronary artery (LMCA) is an exceedingly rare phenomenon, and in the most of them, coronary artery bypass graft is required. We here describe a rare case of this anomaly that concomitantly was associated with supravalvar aortic stenosis and coronary-pulmonary fistula without the presence of conventional collateral circulation in a 16-year-old boy. The patient was admitted to our center with chest pain and dyspnea. Echocardiographic examinations showed supravalvar aortic stenosis with normal function of the aortic valve...

Coronary artery fistulae are congenital cardiac abnormalities characterized by an abnormal communication between a coronary artery and a cardiac chamber, systemic or pulmonary vessel. Most of the cases are asymptomatic and are discovered incidentally during an angiography. We describe a rare case of a right coronary artery fistula draining to the right atrium, manifesting in chest pain and pulmonary arterial hypertension (PAH). The fistula was detected on transesophageal echocardiography during the workup for PAH...

OBJECTIVES: Application of computational fluid dynamics (CFD) to three-dimensional CTCA datasets has been shown to provide accurate assessment of the hemodynamic significance of a coronary lesion. We aim to test the feasibility of calculating a novel CTCA-based virtual functional assessment index (vFAI) of coronary stenoses > 30% and ≤ 90% by using an automated in-house-developed software and to evaluate its efficacy as compared to the invasively measured fractional flow reserve (FFR)...

INTRODUCTION: Smoking is associated with atherosclerotic disease, but there is controversy about its protective nature after acute coronary syndrome (ACS). OBJECTIVE: To determine the impact of smoking on the presentation, treatment and outcome of ACS. METHODS: We analyzed all consecutive patients with ACS in a single center between 2005 and 2014. Current smokers and never-smokers were compared. Independent predictors of in-hospital mortality and of a composite of all-cause mortality, rehospitalization for cardiovascular causes, angiography, percutaneous coronary intervention and coronary artery bypass grafting were assessed by multivariate logistic regression...

PURPOSE: To develop a framework for efficient and simultaneous acquisition of motion-compensated whole-heart coronary MR angiography (CMRA) and left ventricular function by MR and myocardial integrity by PET on a 3T PET-MR system. METHODS: An acquisition scheme based on a dual-phase CMRA sequence acquired simultaneously with cardiac PET data has been developed. The framework is integrated with a motion-corrected image reconstruction approach, so that non-rigid respiratory and cardiac deformation fields estimated from MR images are used to correct both the CMRA (respiratory motion correction for each cardiac phase) and the PET data (respiratory and cardiac motion correction)...

BACKGROUND: Contrast-induced acute kidney injury (CI-AKI), a potentially life-threatening complication of iodinated contrast media in patients with impaired renal function, has attracted increasing attention in recent years. There is overwhelming evidence that the most important pre-disposing factor for a contrast-medium induced nephropathy is the pre-existence of a renal impairment. METHODS: The registry was performed as a part of a quality management project in the Dresden-Friedrichstadt heart catheter laboratory...

Up to 50% of the patients undergoing coronary angiography present no epicardial disease. Most of these patients are women. Takotsubo cardiomyopathy, coronary microvascular dysfunction, and spontaneous coronary artery dissection are the most common syndromes that affect these patients. Their mechanisms are complex, with a interplay between neurohormonal factors and a number of other systems. The present review describes how changes in the estrogen state may lead to changes in vasomotor tone and endothelial dysfunction which result in coronary epicardial and microvascular spasm and coronary arterial wall instability in these three conditions...

Coronary artery anomalies have been reported in Bulldogs and present an increased risk when performing balloon valvuloplasty. Identification of coronary anomalies has been reported using multidetector-row computed tomographic (MDCT) angiography with electrocardiographic gating. However, the utility of non-electrocardiographic-gated 16-row computed tomographic for MDCT for the identification of coronary artery anatomy or anomalies to the authors' knowledge has not been fully investigated. The purpose of this study was to evaluate the feasibility of non-electrocardiographic-gated computed tomographic (CT) angiography to identify coronary anomalies in Bulldogs with pulmonary valve stenosis...

Coronary artery fistulas are rare cardiac conditions which constitute a subgroup of anomalies of the coronary arteries. Though majority are asymptomatic, they may be associated with high prevalence of late symptoms and complications. Accurate identification of the fistulas, their hemodynamic significance and associated conditions generally influence management strategies. Dual source computed tomographic evaluation is valuable in delineating its precise morphology with identification and characterization of associated anomalies, thereby assisting in mapping the ideal treatment option...

BACKGROUND: Patients with nonobstructive coronary artery disease (CAD) have worse outcomes compared with those without CAD; however, few studies have compared the intermediate- and long-term impact of CAD severity as a function of patient sex. METHODS: We evaluated 5-year and long-term all-cause mortality of women and men undergoing elective coronary angiography at a single center by degree of CAD: no CAD (1%-24% stenosis), nonobstructive CAD (25%-69% epicardial stenosis or 25%-49% left main stenosis), or obstructive CAD (epicardial stenosis ≥70% or left main stenosis ≥50%), both overall and after adjusting for baseline clinical risk factors using Cox proportional-hazards models...

AIMS: Out of Hospital Cardiac Arrest (OHCA) is frequently attributed to coronary artery disease, thus guidelines recommend coronary angiography (CAG) for survivors of OHCA. However, the real-world application of these guidelines is unknown, and we sought to evaluate CAG practices in the contemporary OHCA population. METHODS: The Clinical Outcomes Assessment Program (COAP), a Washington State public reporting system, and the Cardiac Arrest Registry to Enhance Survival (CARES), a national registry of OHCA, were matched to characterize OHCA presentations between 2014 and 2015...
