OBJECTIVES: This study aimed to assess current temporal trends in utilization of ICE versus TEE guided closure of interatrial communications, and to compare periprocedural complications and resource utilization between the two imaging modalities. BACKGROUND: While transesophageal echocardiography (TEE) has historically been used to guide percutaneous structural heart interventions, intracardiac echocardiography (ICE) is being increasingly utilized to guide many of these procedures such as closure of interatrial communications...

Auditioning is at the very center of educational and professional life in music and is associated with significant psychophysical demands. Knowledge of how these demands affect cardiovascular responses to psychosocial pressure is essential for developing strategies to both manage stress and understand optimal performance states. To this end, we recorded the electrocardiograms (ECGs) of 16 musicians (11 violinists and 5 flutists) before and during performances in both low- and high-stress conditions: with no audience and in front of an audition panel, respectively...

Cardiac catheterization has greatly contributed to the progress made in the management of congenital heart diseases (CHD). Initially used in diagnosis, it allowed the understanding of heart diseases, their anatomy and hemodynamics. Gradually, the development of interventional cardiology has played a major role in the management of these malformations (Patent ductus arteriosus [PDA] and atrial septal defect [ASD] closure, pulmonary dilatation, percutaneous pulmonary valve implantation…). The development of such technology was made possible through the concomitant development of imaging techniques: fluoroscopy, ultrasound, MRI and CT...

Knowledge of atrial wall thickness (AWT) has the potential to provide important information for patient stratification and the planning of interventions in atrial arrhythmias. To date, information about AWT has only been acquired in post-mortem or poor-contrast CT studies, providing limited coverage and highly variable estimates of AWT. We present a novel contrast agent-free MRI sequence for imaging AWT and use it to create personalized AWT maps and a biatrial atlas. A novel black-blood phase-sensitive inversion recovery protocol was used to image 10 volunteers and 2 atrial fibrillation patients, as proof of concept...

INTRODUCTION: When a young person grows up, they evolve from an independent child to an empowered adult. If an individual has a chronic condition, this additional burden may hamper adequate development and independence. Transition programmes for young persons with chronic disorders aim to provide the necessary skills for self-management and participation in care. However, strong evidence on the effects of these interventions is lacking. Therefore, as part of the STEPSTONES project (Swedish Transition Effects Project Supporting Teenagers with chrONic mEdical conditionS), we propose a trial to assess the effectiveness of a structured, person-centred transition programme to empower adolescents with congenital heart disease in the transition to adulthood...

Foods consist of a large number of different nutrients that are contained in a complex structure. The nature of the food structure and the nutrients therein (i.e., the food matrix) will determine the nutrient digestion and absorption, thereby altering the overall nutritional properties of the food. Thus, the food matrix may exhibit a different relation with health indicators compared to single nutrients studied in isolation. The evidence for a dairy matrix effect was presented and discussed by an expert panel at a closed workshop, and the following consensus was reached: 1) Current evidence does not support a positive association between intake of dairy products and risk of cardiovascular disease (i...

Aims: Sudden cardiac death (SCD) causes a large portion of all mortality in adult congenital heart disease (ACHD) patients. However, identification of high-risk patients remains challenging. Fragmented QRS-complexes (fQRS) are a marker for SCD in patients with acquired heart disease but data in ACHD patients are lacking. We therefore aim to evaluate the prognostic value of fQRS for SCD in ACHD patients. Methods and results: From a multicentre cohort of 25 790 ACHD patients, we included tachyarrhythmic SCD cases (n = 147), and controls (n = 266) matched by age, gender, congenital defect and (surgical) intervention...

The myocardial extracellular matrix (ECM) is the dynamic environment that is fundamental for the structural and physiological homeostasis of the heart. Alterations in ECM homeostasis may lead to diastolic or systolic dysfunction and consequent development of heart failure (HF). For degradation of ECM, matrix metalloproteinases (MMPs) are responsible. To the most frequently analyzed MMPs in relation to HF syndrome belong MMP-2 and MMP-9. This review summarizes the recent knowledge concerning the role of circulating MMP-2 and MMP-9 (i...

Tricuspid regurgitation (TR) is commonly encountered in the management of patients with a variety of cardiovascular diseases. Primary TR is the result of structural abnormalities of the valve or chordal attachments whereas functional TR results from alterations in right ventricular (RV) or right atrial (RA) size, shape or function. The vast majority of TR cases seen in practice are functional in nature and usually results from left-sided heart disease (e.g., mitral valve disease, left ventricular (LV) systolic dysfunction) and/or pulmonary vascular disease, though it also manifests in the presence of isolated chronic atrial fibrillation (AF)...

For the year 2016, more than 20,000 published references can be found in Pubmed when entering the search term "cardiac surgery". Publications last year have helped to more clearly delineate the fields where classic surgery and modern interventional techniques overlap. The field of coronary bypass surgery (partially compared to percutaneous coronary intervention) was enriched by five large prospective randomized trials. The value of CABG for complex coronary disease was reconfirmed and for less complex main stem lesions, PCI was found potentially equal...

OBJECTIVE: Evaluate the effect of structured, guided reflection on patient descriptions of self-care maintenance and management. BACKGROUND: Inadequate HF self-care behaviors are linked to hospitalizations. Symptom monitoring and recognition are precursors to adequate HF self-care. Reflection on actions taken during HF exacerbations may lead to insights and future changes in HF self-care maintenance and management. METHODS: One-group mixed method pre-test/post-test design...

BACKGROUND: Doxorubicin (DOX) is generally recognized to have important cardiotoxic side effects. Studies are contradictory about the interaction between hyperbaric oxygen (HBO2) therapy and doxorubicin-induced cardiomyotoxicity. Recent data suggests that HBO2 therapy can lead to preconditioning of myocardium while generating oxidative stress. Herein we have investigated the effect of HBO2 therapy in a DOX-induced cardiomyocyte injury animal model. METHODS: Twenty-one rats were divided into three equal groups as follows: 1) Group 1 is a control group (without any intervention), used for evaluating the basal cardiac structures and determining the normal value of cardiacs and serum oxidative markers; 2) Group 2 is the doxorubicin group (single dose i...

The use of cardiac ultrasound is fundamental to the understanding of normal heart function and crucial to pathophysiological diagnosis. The growing availability of 3D echocardiography (3DE) over the last decade has allowed its applications to expand from establishing reference values for chamber size and elucidating ventricular mechanics, to assessing valvular disease severity and playing pivotal roles in interventional procedures. Several important advantages of 3DE include eliminating geometric assumptions, quantifying complex geometric shape volumes, viewing structures from any perspective, assessing lesion in simultaneous multiplanes or multislice mode, all of which are not possible with traditional 2D echocardiography (2DE)...
