OBJECTIVE: Non-Invasive foetal electrocardiography (NI-FECG) has the
 potential to provide more additional clinical information for detecting and diagnosing
 fetal diseases. We propose and demonstrate a deep learning approach for fetal QRS
 complex detection from raw NI-FECG signals by using Convolutional Neural Network
 (CNN) model. The main objective is to investigate whether reliable fetal QRS complex
 detection performance can still be obtained from features of single-channel NI-FECG
 signals, without canceling maternal ECG (MECG) signals...

Background: Cardiac redo surgery, especially after a full sternotomy, is considered a high-risk procedure. Minimally invasive mitral valve surgery (MIMVS) is a potential therapeutic approach. However, current developments in interventional cardiology necessitate additional discussion regarding the therapy of choice in high-risk patients. In this context, it is necessary to clarify the perioperative and postoperative risks induced by the factor previous sternotomy in the setting of MIMVS...

Sudden cardiac death (SCD) represents about 25% of deaths in clinical cardiology. The identification of risk factors for SCD is the philosopher's stone of cardiology and the identification of non-invasive markers of risk of SCD remains one of the most important goals for the scientific community.The aim of this review is to analyze the state of the art around the Heart Rate Variability (HRV) as a predictor factor for SCD.HRV is probably the most analyzed index in cardiovascular risk stratification technical literature, therefore an important number of models and methods have been developed...

Interventional radiology is a constantly evolving specialty overlapping with multiple other specialties, including cardiology, vascular surgery, orthopedic surgery, urology, and minimally invasive surgery. Unique ergonomic considerations for interventional radiology include utilization of intraoperative viewing monitors and personal radiation protection equipment. Work-related injuries are common in interventional radiologists,1 often leading to pain while performing procedures or during time away from work...

Cardiac imaging is central to today's pediatric cardiology practice not only to diagnose structural congenital defects and delineate cardiac and extracardiac anatomy but also for determining the hemodynamic impact of the structural defects and acquired pediatric diseases. Not so long ago, clinicians had to heavily rely on angiography as the main cardiac imaging modality to visualize the heart. Particularly, the development of echocardiography in the 1970s and 1980s together with the development of magnetic resonance imaging (MRI) and computed tomography (CT) resulted in a non-invasive diagnostic revolution with diagnostic catheterization becoming obsolete apart for very specific indications...

Inappropriate tests are responsible for longer waiting lists, higher economical costs for the National Health System and major clinical risks due to radiation exposure from prescription abuse of diagnostic testing. Clinical inappropriateness frequently derives from poor knowledge of guidelines, "defensive medicine" approach and/or repeat requests of patients and family members. About one third of non-invasive imaging tests are considered inappropriate.In order to define the most appropriate instruments for the follow-up of the most common cardiovascular diseases with the highest risk of inappropriateness, all the cardiologists of the Veneto Region (Italy), along with the local chapters of the main national cardiology societies and general practitioners have been involved by the Regional Section of the Italian Association of Hospital Cardiologists (ANMCO) in several scientific meetings on the following topics: hypertension, chronic ischemic heart disease, valvular heart disease, heart failure, and atrial fibrillation...

For several years, we have observed the dynamic development of technologies that allow patients to access medical care from the comfort of their homes, without direct contact with the doctor. Innovative solutions based on telemedicine improve care coordination and communication among clinicians, patients, and their families, as well as increases patients' security and gives them greater independence, thus eliminating health care inequalities. The rapidly growth of telemedicine and the adoption of new technologies in clinical practice is also observed in Poland...

BACKGROUND: An association between erectile dysfunction (ED) and cardiovascular (CV) disease (CVD) has long been recognized, and studies suggest that ED is an independent marker of CVD risk. More significantly, ED is a marker for both obstructive and non-obstructive coronary artery disease (CAD) and may reveal the presence of subclinical CAD in otherwise asymptomatic men. AIM: To discuss the role of ED as an early marker of subclinical CVD; describe an approach to quantifying that burden; and propose an algorithm for the evaluation and management of CV risk in men 40-60 years of age with vasculogenic ED, those presumed to have the highest risk for a CV event...

Ischaemic heart disease (IHD) is the leading cause of mortality in the Western world. Therefore, to focus on those at risk of having IHD while at the same time avoiding unnecessary patient concern, it is important to have diagnostic tools capable of refuting an IHD diagnosis. Within the past 30 years, myocardial perfusion imaging (MPI) has been used increasingly to detect myocardial perfusion defects. MPI is a safe and non-invasive method with a sensitivity and specificity of > 90%. The aim of this study was to evaluate the long-term prognostic outcome after a normal MPI...

Atrial fibrillation (AF) is a cardiac dysrhythmia commonly seen in clinical practice especially after cardiac surgery. It is associated with increased morbidity and mortality for the patients. The pathogenesis of AF is not exactly understood yet, but there is growing data about the relationship between AF and inflammation. Cardiac surgery itself is a big source for inflammation. It causes major surgical trauma, ischemia/reperfusion injury, hypothermia, low arterial pressure, and the equipment of cardiopulmonary bypass makes a large foreign surface thus it activates inflammatory response...

The symptom cluster of shortness of breath (SOB) contributes significantly to the outpatient workload of cardiology services. The workup of these patients includes blood chemistry and biomarkers, imaging and functional testing of the heart and lungs. A diagnosis of diastolic heart failure is inferred through the exclusion of systolic abnormalities, a normal pulmonary function test and normal hemoglobin, coupled with diastolic abnormalities on echocardiography. Differentiating confounders such as obesity or deconditioning in a patient with diastolic abnormalities is difficult...

BACKGROUND: The clinical relevance of non-invasively derived pulmonary arterial pressure (PAP) by Doppler echocardiography (DE) has been questioned in the past. However, transthoracic echocardiography is used as a cornerstone examination for patients with dyspnea and suspected pulmonary hypertension (PH). This study aimed to evaluate the prognostic value of non-invasive assessed PAP in a large population of patients with known or suspected cardiopulmonary disease. METHODS: The analyses are based on data of patients of a tertiary cardiology center that received right heart catheterization (RHC) as well as non-invasively assessed PAP by DE within five days, and includes serological and clinical parameters in a retrospective follow-up for up to eight years...

Authors have proposed a concept of guidelines for applying the ambulatory complex cardiovascular rehabilitation (ACCVR) into the clinical practice in Slovakia. As a background they have used an actual cardiovascular mortality and morbidity data from home country and abroad as well. They emphasize the non-optimal situation in this aspect which may not be solved by the increasing supporting the invasive revascularization methods and by the intensifying pharmacotherapy only, because the favourable effects of these procedures is timely missing if it is not accompanied by the therapeutic lifestyle changes...

BACKGROUND: The correct perioperative management of antiplatelet therapy (APT) in patients undergoing non-cardiac surgery (NCS) is often debated by clinicians. American College of Cardiology (ACC) and American Heart Association (AHA) guidelines recommend postponing elective NCS at least 3 months after stent implantation. Regardless of the timing of surgery, ACC/AHA guidelines recommend continuing at least ASA throughout the perioperative period and ideally continuing dual APT (DAPT) therapy "unless surgery demands discontinuation...
