Restrictive cardiomyopathies (RCMs) are a diverse group of myocardial diseases with a wide range of aetiologies, including familial, genetic and acquired diseases and ranging from very rare to relatively frequent cardiac disorders. In all these diseases, imaging techniques play a central role. Advanced imaging techniques provide important novel data on the diagnostic and prognostic assessment of RCMs. This EACVI consensus document provides comprehensive information for the appropriateness of all non-invasive imaging techniques for the diagnosis, prognostic evaluation, and management of patients with RCM...

For the last five years, invasive cardiology in Poland has developed extensively. Currently, 98% of the 161 Polish cathlabs operate in 24/7 mode, 37 of them supported by cardiac surgery departments on-site. A certification curriculum for interventional cardiology operators is supported by dedicated workshops and scientific meetings during national conferences. The rise in the number of coronary angiographies and PCIs was paralleled by an increased use of drug-eluting stents, bioresorbable vascular scaffolds and physiologic assessment of coronary arteries...

Although coronary computed tomography angiography (CCTA) has shown promise as a "gatekeeper" to invasive coronary angiography (ICA) in longitudinal cohort studies, it remains unknown whether the strategy of selective ICA by initial performance of CCTA is either safe or effective when compared with a direct ICA strategy in patients with an American Heart Association (AHA)/American College of Cardiology (ACC) guideline-directed indication for ICA. OBJECTIVES: The CONSERVE trial is a prospective randomized multicenter trial to determine the clinical effectiveness of "selective catheterization" vs "direct catheterization" strategies for stable patients with suspected but without known coronary artery disease, who meet AHA/ACC guideline indication for ICA...

The field of nuclear cardiology has changed considerably over recent years, with greater attention paid to safety and radiation protection issues. The wider usage of technetium-99m (Tc-99m)-labeled radiopharmaceuticals for single-photon emission computed tomography (SPECT) imaging using gamma cameras has contributed to better quality studies and lower radiation exposure to patients. Increased availability of tracers and scanners for positron emission tomography (PET) will help further improve the quality of studies and quantify myocardial blood flow and myocardial flow reserve, thus enhancing the contribution of non-invasive imaging to the management of coronary artery disease...

Cardiac output is a key parameter in the assessment of cardiac function, and its measurement is fundamental to the diagnosis, treatment, and prognostic evaluation of all heart diseases. Until recently, cardiac output determination during exercise had been only possible through invasive methods, which were not practical in the clinical setting. Since oxygen uptake (V.O2) is cardiac output times arteriovenous content difference [C(a-v)O2)], evaluation of cardiac output is usually included its measurement. Because of the difficulty of directly measuring peak exercise cardiac output, indirect surrogate parameters have been proposed, but with only modest clinical usefulness...

Percutaneous therapies for congenital heart disease have evolved rapidly in the past 3 decades. This has occurred despite limited investment from industry and support from regulatory bodies resulting in a lack of specific device development. Indeed, many devices remain off-label with a best-fit approach often required, spurning an innovative culture within the subspecialty, which had arguably laid the foundation for many of the current and evolving structural heart interventions. Challenges remain, not least encouraging device design focused on smaller infants and the inevitable consequences of somatic growth...

Non-invasive imaging plays a critical role in managing patients with cardiovascular disease. Although subjective visual interpretation remains the clinical mainstay, quantitative analysis facilitates objective, evidence-based management, and advances in clinical research. This has driven developments in computing and software tools aimed at achieving fully automated image processing and quantitative analysis. In parallel, machine learning techniques have been used to rapidly integrate large amounts of clinical and quantitative imaging data to provide highly personalized individual patient-based conclusions...

Aortic stenosis is the most common valvular heart disease in the developed world. About 7% of the population over age 65 years suffers from degenerative aortic stenosis. The prognosis of patients with symptomatic severe aortic stenosis is dismal without valve replacement. Even though the American College of Cardiology recommends aortic valve replacement to treat this condition as a class I recommendation, approximately one third of these patients over the age of 75 years are not referred for surgery. Typically, this is from concern about prohibitive surgical risk associated with patient frailty, comorbidities, age, and severe left ventricular dysfunction...

PTA is a collection of pus located between the tonsillar capsule and the pharyngeal constrictor muscle. It is considered a complication of acute tonsillitis and is the most prevalent deep neck infection (approximately 2000 cases annually in Denmark) and cause of acute admission to Danish ENT departments. Teenagers and young adults are most commonly affected and males may predominate over females. However, no studies of age- and gender-stratified incidence rates have previously been published. Furthermore, smoking may be associated with increased risk of peritonsillar abscess (PTA) development, although the magnitude of the association has not been estimated...

Accurate cardiovascular imaging is essential for the successful management of patients with congenital heart disease (CHD). Echocardiography and angiography have been for long time the most important imaging modalities in pediatric cardiology, but nuclear medicine has contributed in many situations to the comprehension of physiological consequences of CHD, quantifying pulmonary blood flow symmetry or right-to-left shunting. In recent times, remarkable improvements in imaging equipments, particularly in multidetector computed tomography and magnetic resonance imaging, have led to the progressive integration of high resolution modalities in the clinical workup of children affected by CHD, reducing the role of diagnostic angiography...

This paper proposes a five-stage based methodology to extract the fetal electrocardiogram (FECG) from the single channel abdominal ECG using differential evolution (DE) algorithm, extended Kalman smoother (EKS) and adaptive neuro fuzzy inference system (ANFIS) framework. The heart rate of the fetus can easily be detected after estimation of the fetal ECG signal. The abdominal ECG signal contains fetal ECG signal, maternal ECG component, and noise. To estimate the fetal ECG signal from the abdominal ECG signal, removal of the noise and the maternal ECG component presented in it is necessary...
