Phonocardiogram (PCG) monitoring on newborns is one of the most important and challenging tasks in the heart assessment in the early ages of life. In this paper, we present a novel approach for cardiac monitoring applied in PCG data. This basic system coupled with denoising, segmentation, cardiac cycle selection and classification of heart sound can be used widely for a large number of the data. This paper describes the problems and additional advantages of the PCG method including the possibility of recording heart sound at home, removing unwanted noises and data reduction on a mobile device, and an intelligent system to diagnose heart diseases on the cloud server...

BACKGROUND: The quality of in-hospital resuscitation is poor and may be affected by the clinical experience and cardiopulmonary resuscitation (CPR) training. This study aimed to investigate the clinical experience, self-perceived skills, CPR training and knowledge of the guidelines on when to abandon resuscitation among physicians of cardiac arrest teams. METHODS: We performed a nationwide cross-sectional study in Denmark. Telephone interviews were conducted with physicians in the cardiac arrest teams in public somatic hospitals using a structured questionnaire...

BACKGROUND Heparin-induced thrombocytopenia (HIT) is a rare but life-threatening complication of heparin administration. It can present a major clinical dilemma for physicians caring for patients requiring life-saving urgent or emergent cardiac surgery. Studies have been published examining the use of alternative anticoagulants for patients undergoing cardiopulmonary bypass (CPB), however, evidence does not clearly support any particular approach. Presently, there are no large-scale, prospective randomized studies examining the impact of alternative anticoagulants on clinical outcomes for HIT-positive patients requiring cardiac surgery...

AIM: To evaluate the prevalence of advance directives and their impact on the management of out-of-hospital cardiac arrest (OHCA) victims. METHODS: We analyzed data extracted from the French national registry of adult OHCA patients (RéAC). The data concerned the emergency medical services (EMS) of a Paris suburb over the period 01/01/2013 to 30/11/2015. The primary endpoint was the prevalence of advance directives. Secondary endpoints were the characteristics of the population, of cardiac arrest, and of basic life support as well as outcomes in patients with or without advance directives...

This randomized controlled trial, conducted in a UK University nursing department, compared student nurses' performance during a simulated cardiac arrest. Eighteen teams of four students were randomly assigned to one of three scenarios: 1) no family witness; 2) a "quiet" family witness; and 3) a family witness displaying overt anxiety and distress. Each group was assessed by observers for a range of performance outcomes (e.g. calling for help, timing to starting cardiopulmonary resuscitation), and simulation manikin data on the depth and timing of three cycles of compressions...

Despite the best efforts of event producers and on-site medical teams, there are sometimes serious illnesses, life-threatening injuries, and fatalities related to music festival attendance. Producers, clinicians, and researchers are actively seeking ways to reduce the mortality and morbidity associated with these events. After analyzing the available literature on music festival health and safety, several major themes emerged. Principally, stakeholder groups planning in isolation from one another (ie, in silos) create fragmentation, gaps, and overlap in plans for major planned events (MPEs)...

BACKGROUND: Treating patients who are critically ill with radiotherapy (RT) brings a unique set of challenges as it involves treating patients who require mechanical life support, unconventional positioning, and a multidisciplinary team approach to ensure safety. However, when the benefits of such treatment outweigh the risks, the challenges can be overcome, as demonstrated in this unique case of cardiac angiosarcoma. CASE DESCRIPTION: This is a case of a 42-year-old female with a right sided cardiac angiosarcoma who quickly developed cardiac tamponade and respiratory failure related to compression of her right heart by the tumor...

Aortopulmonary window is a rare cardiac developmental anomaly characterised by a communication between the ascending aorta and the pulmonary artery. Aortopulmonary window may be isolated or associated with cardiac defects such as ventricular septal defect, atrial septal defect, interrupted aortic arch, and tetralogy of Fallot. We report a case of aortopulmonary window associated with aberrant subclavian artery based on fetal two-dimensional echocardiogram. The mother was referred for fetal echocardiography because of multiple fetal anomalies...

Premature death in untreated children with Hurler syndrome (HS) in the first decade of life is largely due to life-threatening cardiopulmonary complications. We examined the long-term survival and cardiopulmonary outcome in 54 children undergoing haematopoietic stem cell transplantation (HSCT) at the Royal Manchester Children's Hospital from 1985 to 2008. The median age at first HSCT was 15.1 months. Eighteen had graft failure and nine died after first HSCT. Of 18 patients with graft failure, 17 underwent second HSCT and the remaining one was lost to follow-up (LOF)...

BACKGROUND: Most cardiac arrest (CA) patients remain comatose post-resuscitation, prompting goals-of-care (GOC) conversations. The impact of these conversations on patient outcomes has not been well described. METHODS: Patients (n=385) treated for CA in Columbia University ICUs between 2008-2015 were retrospectively categorized into various modes of survival and death based on documented GOC discussions. Patients were deemed "medically unstable" if there was evidence of hemodynamic instability at the time of discussion...

Among the most significant factors affecting quality of life in individuals with critical congenital heart disease (CCHD) are neurodevelopmental challenges, including deficits in visuospatial processing and academic achievement. Few studies have compared outcomes across CCHD subgroups, despite their significant differences in anatomy/physiology and medical/surgical courses. This study compared visuospatial processing abilities using the Developmental Scoring System for the Rey-Osterrieth Complex Figure (DSS-ROCF) across groups of adolescents with CCHD (d-transposition of the great arteries [TGA, n = 139], Tetralogy of Fallot [TOF, n = 68], single-ventricle cardiac anatomy requiring the Fontan operation [SVF, n = 145]) and a group of healthy controls (CTR, n = 111), and examined the validity of visuospatial processing in predicting concurrent academic outcomes...

There is a subset of patients who have recurrent ventricular tachycardia despite optimal medical management with pharmacologic therapy and catheter ablation. The cardiac sympathetic nervous system is responsible for triggering and perpetuating ventricular arrhythmias, and surgery can reduce the sympathetic stimulation to the heart. Evidence supports the use of left cardiac sympathetic denervation in recurrent ventricular arrhythmias for long QT syndrome and catecholaminergic polymorphic ventricular tachycardia...

Extracorporeal life support (ECLS) is a very effective bridging therapy in patients with refractory ventricular tachycardia (VT) associated with cardiogenic shock. A moribund patient in extremis, is not amenable to optimization by standard ACC/AHA guidelines. New approaches and novel salvage techniques are necessary to improve outcomes in patients with refractory clinical settings such as malignant ventricular arrhythmias, cardiac arrest, cardiogenic shock and/or pulmonary failure until further management options are explored...

Nicholson Yam, David Michael McMullan
Extracorporeal life support (ECLS) is used for patients in isolated or combined cardiopulmonary failures. The use of ECLS to rescue patients with cardiac arrest that is refractory to conventional cardiopulmonary resuscitation has been shown to improve survival in many patient populations. Increasing recognition of the survival benefit associated with extracorporeal cardiopulmonary resuscitation (ECPR) has led to increased use of ECPR during the past decade. This review provides an overview of ECPR utilization; population-based clinical outcomes, resource utilization and costs associated this advanced form of life support therapy...

OBJECTIVE: Cardiac catheterization in patients receiving extracorporeal life support (ECLS) has previously been shown to be safe and, in many cases, therapeutic. However, the influence of cardiac catheterization on clinical outcomes in this patient population has not been clearly defined. METHODS: A single institution, retrospective review of all pediatric cardiac ECLS patients who underwent cardiac catheterization between January 2006 and September 2015 was performed...
