Visibility of Bioresorbable Vascular Scaffold in Intravascular Ultrasound Imaging.

Bioresorbable vascular scaffold (BVS) has recently been spotlighted for its unique characteristics of absorbing into blood vessels and eventually disappearing. Although intravascular ultrasound (IVUS) is the most common guiding tool for stent deployment, the echogenicity of BVS struts has changed as the center of stent lumen and scanning rotation are not concentric, which may cause a critical erro...

Myocardial B cells are a subset of circulating lymphocytes with delayed transit through the heart.

Current models of B lymphocyte biology posit that B cells continuously recirculate between lymphoid organs without accumulating in peripheral healthy tissues. Nevertheless, B lymphocytes are one of the most prevalent leukocyte populations in the naive murine heart. To investigate this apparent inconsistency in the literature, we conducted a systematic analysis of myocardial B cell ontogeny, traffi...

Impact of admission glycaemia on the annual risk of major cardiovascular events and development of type 2 diabetes mellitus in patients with non-ST-elevation acute coronary syndrome undergoing percutaneous coronary intervention.

Elevated admission glycaemia (ABG) in a patient with or without type 2 diabetes (T2DM) is associated with adverse consequences. There is still a lack of accurate data on the adverse effects of ABG on the risk of major cardiovascular events and the development of T2DM in patients hospitalized for unstable angina (UA) or non-ST elevation myocardial infarction (NSTEMI) undergoing percutaneous coronar...

Trends in length of stay following acute coronary syndrome hospitalisation in New Zealand 2006-2016: ANZACS-QI 32 study.

Length of hospital stay (LOS) for acute coronary syndrome (ACS) has important clinical and cost implications. We report recent trends and predictors of ACS hospitalisation LOS in New Zealand.

How to replace a bioprosthetic aortic valve within the Bentall graft.

The Bentall procedure using a bioprosthesis-containing conduit carries the risk of structural valve deterioration within the patients' lifetime. Failed aortic bioprosthesis replacement requires a redo aortic root replacement that is associated with significant morbidity and mortality. We describe an original "neo-annulus" technique of aortic valve replacement (AVR) within the Bentall graft. This t...

Enlarged coronary sinus thrombosis after repair of Ebstein's anomaly.

A 58-year-old woman was referred to our hospital with progressively increasing breathlessness. She reported a history of bioprosthetic valve implantation for tricuspid valve replacement and direct closure of an atrial septal defect for Ebstein's anomaly, 31 years before presentation. Transthoracic echocardiography revealed prosthetic valve failure, an enlarged coronary sinus, and severe mitral reg...

Whole blood gene expression profiling distinguishes systemic sclerosis-overlap syndromes from other subsets.

Among autoimmune rheumatic diseases, systemic sclerosis (SSc) is especially challenging due to its clinical diversity, reflected by the extent of skin and internal organ involvement . Besides the two major subsets, limited and diffuse SSc (lcSSc, dcSSc), a substantial number of SSc cases exhibit overlap features of another rheumatic disease, summarized as SSc-overlap syndromes. A few of these are...

Multimodal functional and still imaging of a transplanted human heart reanimated using Visible Heart® methodologies.

Our research team obtained a human heart with the right lung attached from a recent transplantation patient via a research collaboration with LifeSource, a local organ procurement organization. The heart and lungs were not viable for transplant given the patient's medical history and were subsequently offered to the University of Minnesota for research purposes.

Contemporary outcomes of coronary artery bypass grafting in obese patients.

This study evaluated the impact of obesity on outcomes of coronary artery bypass grafting (CABG) with particular attention to cases using bilateral internal mammary arteries (BIMAs).

Migrated fractured sternal wire in proximity to the main pulmonary artery: Case report and review.

We present a case of a 83-year-old man with a prior history of coronary artery bypass who presented to his family physician with progressive symptoms that raised concern for heart failure exacerbation. A chest X-ray was performed, which showed a fractured topmost sternal wire in the lateral projection and indicated that the sternal wire had migrated into the anterior mediastinum. An emergent elect...

Sex Differences in Exercise Capacity and Quality of Life in Heart Failure with Preserved Ejection Fraction: A Secondary Analysis of the RELAX and NEAT-HFpEF Trials.

Few studies have compared clinical characteristics, echocardiographic parameters, exercise capacity, and quality of life between women and men with heart failure with preserved ejection fraction (HFpEF).

Performance of a deep learning algorithm for the evaluation of CAD-RADS classification with CCTA.

Artificial intelligence (AI) is increasing its role in diagnosis of patients with suspicious coronary artery disease. The aim of this manuscript is to develop a deep convolutional neural network (CNN) to classify coronary computed tomography angiography (CCTA) in the correct Coronary Artery Disease Reporting and Data System (CAD-RADS) category.

Economic burden of maternal morbidity - A systematic review of cost-of-illness studies.

To estimate the economic burden of common health problems associated with pregnancy and childbirth, such as incontinence, mental health problems, or gestational diabetes, excluding acute complications of labour or birth, or severe acute adverse maternal outcomes.

En-Bloc Simultaneous Heart-Liver Transplantation in Adult Patients.

Complexity of combined heart-liver transplantation has resulted in low adoption rates. We report a case series of adult patients receiving en-bloc heart-liver transplantation (HLTx), describe technical aspects, and discuss benefits of the technique.

Effect of Elevated Calcium Score on Normal Myocardial Perfusion Study on Clinician Management of Coronary Artery Disease Risk Factors.

Elevated coronary artery calcium (CAC) scores are associated with higher cardiovascular risk even with normal stress myocardial perfusion imaging (MPI). Whether referring providers appropriately manage subclinical cardiovascular (CV) disease is unclear. We hypothesized that ordering clinicians would intensify medical therapy for CV disease in response to normal MPI & CAC≥300. We conducted a coho...

Comparative Performance of Pulmonary Ultrasound, Chest Radiograph, and CT Among Patients With Acute Respiratory Failure.

The study goal was to concurrently evaluate agreement of a 9-point pulmonary ultrasound protocol and portable chest radiograph with chest CT for localization of pathology to the correct lung and also to specific anatomic lobes among a diverse group of intubated patients with acute respiratory failure.

Correction and Control of Hyperammonemia in Acute Liver Failure: The Impact of Continuous Renal Replacement Timing, Intensity, and Duration.

Hyperammonemia is a key contributing factor for cerebral edema in acute liver failure. Continuous renal replacement therapy may help reduce ammonia levels. However, the optimal timing, mode, intensity, and duration of continuous renal replacement therapy in this setting are unknown. We aimed to study continuous renal replacement therapy use in acute liver failure patients and to assess its impact ...

Suppression of Superoxide-Hydrogen Peroxide Production at Site IQ of Mitochondrial Complex I Attenuates Myocardial Stunning and Improves Postcardiac Arrest Outcomes.

Cardiogenic shock following cardiopulmonary resuscitation for sudden cardiac arrest is common, occurring even in the absence of acute coronary artery occlusion, and contributes to high rates of postcardiopulmonary resuscitation mortality. The pathophysiology of this shock is unclear, and effective therapies for improving clinical outcomes are lacking.

Heart Rate Control during Experimental Sepsis in Mice: Comparison of Ivabradine and β-Blockers.

Tachycardia is a hallmark of sepsis. An elevated heart rate could impair ventricular filling and increase myocardial oxygen demand. β-Blockers and ivabradine (a selective inhibitor of If channels in the sinoatrial node) are both able to control sinus tachycardia, with the latter drug being devoid of negative inotropic effect. This work aimed at assessing the hemodynamic effects of ivabradine as c...

PrEP implementation behaviors of community-based HIV testing staff: A mixed methods approach using latent class analysis.

Pre-exposure Prophylaxis (PrEP) is an important option for HIV prevention, but the approach has reached a limited number of people at risk for HIV infection.

Low Radiation Dose and High Image Quality of 320-Row Coronary Computed Tomography Angiography Using a Small Dose of Contrast Medium and Refined Scan Timing Prediction.

Patient Based Bull's Eye Map Display of Coronary Artery and Ventricles From Coronary Computed Tomography Angiography.

Coronary computed tomography angiography is widely used in clinical practice. Although 3-dimensional (D) volume rendering is useful for interpretation of coronary path and territory, 2D output is common for image interpretation. Most picture archiving and communication system is incapable of manipulating 3D due to insufficient graphic specification. Thus, 2D bull's eye map display is frequently us...
