BACKGROUND: Contrast-induced acute kidney injury (CI-AKI), defined as a serum creatinine increase ≥0.5 mg/dL or ≥25% within 72 hours after contrast exposure, is a common complication of procedures requiring contrast media and is associated with increased short- and long-term morbidity and mortality. Few studies describe the effects of CI-AKI in a large-scale acute coronary syndrome population, and the relationship between CI-AKI and bleeding events has not been extensively explored...

Total plaque area (TPA), maximum plaque thickness and intima media thickness (IMT) in the carotid arteries of 431 patients aged 27-88 years were measured 1 day before a planned coronary artery angiography without any clinical knowledge about the patient. Age-related cut-off values of the TPA for the presence of coronary stenosis were evaluated. Using ultrasound four types of carotid artery atherosclerosis were identified. The accuracy of detection of cardiovascular coronary stenosis was 87% for types III and IVb...

Contrast-induced acute kidney injury (CI-AKI) is a serious complication that is difficult to predict in patients with chronic kidney disease (CKD) undergoing percutaneous coronary intervention (PCI). The aim of this study was to investigate predictors and clinical outcomes of CI-AKI in patients with CKD after PCI. A total of 297 patients with CKD who underwent PCI from September 2006 to December 2011 were enrolled. CI-AKI was defined as serum creatinine level either ≥25% or ≥0.5 mg/dl from baseline within 72 hours after PCI...

BACKGROUND: Prior studies have shown that late gadolinium enhancement (LGE) by cardiac magnetic resonance (CMR) can detect focal fibrosis in aortic stenosis (AS), suggesting that it might predict higher mortality risk. OBJECTIVES: This study was conducted to evaluate whether LGE-CMR can predict post-operative survival in patients with severe AS undergoing aortic valve replacement (AVR). METHODS: We prospectively evaluated survival (all-cause and cardiovascular disease related) according to LGE-CMR status in 154 consecutive AS patients (96 men; mean age: 74 ± 6 years) without a history of myocardial infarction undergoing surgical AVR and in 40 AS patients undergoing transcatheter aortic valve replacement (TAVR)...

BACKGROUND/AIMS: Contrast medium-induced acute kidney injury (CI-AKI) is an important complication following the use of iodinated contrast media. It accounts for a significant number of hospital-acquired acute kidney injuries and is associated with increased in-hospital and long-term mortality and immense health care costs. We evaluated whether the presence of peripheral arterial occlusive disease (PAD) affects the incidence of CI-AKI following heart catheterization. METHODS: The impact of PAD on the frequency of CI-AKI after heart catheterization was analysed in the prospective single-centre Dialysis-versus-Diuresis trial (January 2001 to July 2004)...

Severe anaphylactoid reaction after the use of iodinated contrast media are rare but can contraindicate the use of contrast agent. It was the case of a 53-year-old woman suffering from symptomatic severe aortic stenosis, recused for cardiac surgery because of deleterious effects of chest-wall irradiation, with porcelain aorta. We decided to implant a 23-mm Edwards(®) SAPIEN(®) transcatheter aortic valve via a femoral route without using any contrast media. The implantation was successful after surgical approach of the femoral artery, transesophageal echocardiography guiding, and localization of native leaflets and coronary trunk with catheters...

The administration of bone marrow-derived stem cells may provide a new treatment option for patients with heart failure. Transcatheter cell injection may require multi-imaging modalities to optimize delivery. This study sought to evaluate whether endomyocardial injection of mesenchymal precursor cells (MPCs) could be guided by real-time 3D echocardiography (RT3DE) in treating chronic, postinfarction (MI) left ventricular (LV) dysfunction in sheep. Four weeks after induction of an anterior wall myocardial infarction in 39 sheep, allogeneic MPCs in doses of either 25 × 10(6) (n = 10), 75 × 10(6) (n = 9), or 225 × 10(6) (n = 10) cells or nonconditioned control media (n = 10) were administered intramyocardially into infarct and border zone areas using a catheter designed for combined fluoroscopic and RT3DE-guided injections...

HISTORY AND ADMISSION FINDINGS: Myocardial contrast echocardiography guided alcohol septal ablation (PTSMA) is an established treatment for symptomatic hypertrophic obstructive cardiomyopathy (HOCM). Most important properties of the optimal echocardiographic contrast agent are good contrast imaging and sufficient stability without fast washing out. HOCM was diagnosed in a 49-year-old female patient 4 years before first admission. Despite optimal medical treatment the patient was highly symptomatic with angina pectoris and dyspnoea NYHA II-III...

BACKGROUND: Modern fluoroscopic angiography systems permit rendering of three-dimensional volumetric data sets using rotational angiography (3D-RA). Along with magnetic resonance imaging (MRI) or multi-detector-row computed tomography (MDCT) data sets, they can be fused with live fluoroscopy images for roadmapping during therapeutic procedures, but the value of multimodality fused data sets has not been clarified. METHODS: In a pediatric cardiac catheterization laboratory, we analyzed 78 interventional cardiovascular procedures in which 3D models of 3D-RA, MRI, or MDCT were used for 3D-guidance...

Catheter-induced aortocoronary dissection is a rare, but serious complication during diagnostic coronary catheterization or percutaneous coronary intervention (PCI). Immediate coronary artery stenting of the entry point is one of therapeutic options. However, PCI itself may worsen the dissection, because contrast injection has been reported to be a risk factor for the extension of dissected aorta. We present a case of 79-year-old male suffering from inferior acute myocardial infarction due to the catheter-induced aortocoronary dissection...

BACKGROUND: Although an intracoronary frequency-domain optical coherence tomography (FD-OCT) system overcomes several limitations of the time-domain OCT (TD-OCT) system, the former requires injection of contrast media for image acquisition. The increased total amount of contrast media for FD-OCT image acquisition may lead to the impairment of renal function. The safety and usefulness of the non-occlusion method with low-molecular-weight dextran L (LMD-L) via a guiding catheter for TD-OCT image acquisition have been reported previously...

BACKGROUND: There is limited data about the influence of timing of cardiac surgery in relation to diagnostic angiography and/or the impact of the amount of contrast media used during angiography on the occurance of acute renal failure (ARF). Therefore, in the present study the effect of the time interval between diagnostic angiography and cardiac surgery and also the amount of contrast media used during the diagnostic procedure on the incidence of ARF after cardiac surgery was investigated...

With the introduction of targeted coronary artery angiography to post-mortem computed tomography (PMCT) it is now possible to assess the coronary arteries and left ventricle after death without, case dependent, the necessity to undertake an invasive autopsy. The purpose of this pictorial review is to act as a walk through aid memoire and educational learning document for radiologists and pathologists alike who may be new to the use and interpretation of targeted PMCT angiography. By using an example scanning protocol, which uses both positive and negative (air) contrast mediums, this pictorial review provides a systematic approach to vessel and ventricular assessment that is based upon clinical cardiac angiography but adapted to PMCT...

OBJECTIVES: This study aimed to test whether advanced cardiovascular injection (ACI) via 4 French (Fr) catheters is more advantageous than manual injection with 6 Fr catheters. BACKGROUND: For coronary angiography, proponents of contrast media ACI believe it utilizes smaller-diameter catheters when compared with manual injection, without compromising the quality of the angiogram, and has the potential to reduce the amount of contrast used and lessen the use of closure devices...

BACKGROUND: Previous studies have shown the cost benefit of fractional flow reserve (FFR)--guided coronary revascularization in the patient with multivessel borderline coronary artery stenoses. However; they have been performed in the Bare-metal stent era. It is a challenge to demonstrate the benefit of the FFR-guided coronary revascularization in the patient with multivessel coronary disease (MVD) in the drug-eluting era in Thai patients. MATERIAL AND METHOD: Forty-nine patients with MVD (71 stenotic vessels) underwent FFR-guided revascularization (FFR group) compared with forty-nine patients with MVD (79 stenotic vessels) underwent traditional PCI (Traditional group) on the basis of visual estimation of the stenotic lesion...
