OBJECTIVE: Hospital readmissions are increasingly becoming a metric for quality in the current landscape of changing and cost effective medicine. However, no 30-d readmission rates have been established for pediatric cardiac medical patients in the United States. Thus, the objective was to determine 30 d readmission rates and risk factors associated with readmission for pediatric cardiac patients, hypothesizing that pediatric cardiac patients would have significantly higher readmission rates than their general pediatric counterparts...

Thrombotic thrombocytopenic purpura (TTP) has >90% mortality without therapeutic plasma exchange (TPE). Despite TPE, approximately 10% of patients still die, presumably from cardiac ischemia. We sought clinical or laboratory parameters associated with death by reviewing the records of all patients hospitalized with acquired TTP in our institution for 10 years, and collect demographics and results for hemoglobin, platelet count, creatinine, lactate dehydrogenase, transaminases, total bilirubin, creatinine kinase (CK), CK-MB, and troponin I...

BACKGROUND: The long-term outcomes of patients undergoing interventions for congenital heart disease (CHD) remain largely unknown. We linked the Pediatric Cardiac Care Consortium (PCCC) with the National Death Index (NDI) and the United Network for Organ Sharing Dataset (UNOS) registries to study mortality and transplant occurring up to 32 years postintervention. The objective of the current analysis was to determine the sensitivity of this linkage in identifying patients who are known to have died or undergone heart transplant...

Julien Oster, Gari D Clifford
Atrial fibrillation (AF) is the most common cardiac arrhythmia, but is currently under-diagnosed since it can be asymptomatic. Early detection of AF could be highly beneficial for the prevention of stroke, which is one major risk associated with AF, with a five fold increase. mHealth applications have been recently proposed for early screening of paroxysmal AF. Several automatic AF detections have been suggested, and they are mostly based on features extracted from the RR interval time-series, since this is more robust to ambulatory noise than p-wave based algorithms...

BACKGROUND: Adult patients with CHD often require complex operations, and indications for particular aspects of the operation are sometimes unclear. The aims of our study were as follows: to characterise concomitant procedures performed during adult congenital cardiac surgery, and to better define the risk involved with performing concomitant procedures during a single operation. METHODS: We retrospectively studied 458 adult congenital cardiac surgical patients...

The electrocardiogram (ECG) is a well studied signal from which many clinically relevant parameters can be derived, such as heart rate. A key component in the estimation of these parameters is the accurate detection of the R peak in the QRS complex. While corruption of the ECG by movement artefact or sensor failure can result in poor delineation of the R peak, use of synchronously measured signals could allow for resolution of the R peak even scenarios with poor quality ECG recordings. Robust estimation of R peak locations from multimodal signals facilitates real time monitoring and is likely to reduce false alarms due to inaccurate derived parameters...

This editorial reviews the background issues, the design, the key achievements, and the follow-up research generated as a result of the PhysioNet/Computing in Cardiology (CinC) Challenge 2014, published in the concurrent focus issue of Physiological Measurement. Our major focus was to accelerate the development and facilitate the comparison of robust methods for locating heart beats in long-term multi-channel recordings. A public (training) database consisting of 151 032 annotated beats was compiled from records that contained ECGs as well as pulsatile signals that directly reflect cardiac activity, and other signals that may have few or no observable markers of heart beats...

BACKGROUND: The American Heart Association recommends a "meticulous history" when evaluating patients with an initial episode of syncope. However, little is known about which historical features are most helpful in identifying children with undiagnosed cardiac syncope. OBJECTIVES: Our objectives were 1) to describe the cardiac disease burden in Emergency Department (ED) syncope presentations, and 2) to identify which historical features are associated with a cardiac diagnosis...

BACKGROUND: Although much is known about morbidity and mortality, there are limited data focussing on the financial aspect of the Norwood operation. Our objective is to characterise the hospitalisation and detail the hospital costs. METHODS: We retrospectively studied 86 newborns with hypoplastic left heart syndrome who underwent Norwood palliation between 2008 and 2012. Clinical and financial data were collected. Financial data have been reported for 2011-2012...

OBJECTIVES: Pulmonary artery banding is the initial palliative surgery in patients with single ventricle cardiac anomalies presenting with unrestricted pulmonary blood flow. Reported mortality in those receiving pulmonary artery banding is high, and its application in patients with single ventricle anomalies and arch obstruction is controversial. We report current-era results after pulmonary artery banding in patients with single ventricle anomalies, including those with arch obstruction...

The electrocardiogram (ECG) is often acquired during magnetic resonance imaging (MRI), but its analysis is restricted by the presence of a strong artefact, called magnetohydrodynamic (MHD) effect. MHD effect is induced by the flow of electrically charged particles in the blood perpendicular to the static magnetic field, which creates a potential of the order of magnitude of the ECG and temporally coincident with the repolarisation period. In this study, a new MHD model is proposed by using MRI-based 4D blood flow measurements made across the aortic arch...

OBJECTIVE: The effect of genotype on the outcomes of infant cardiac operations has not been well established. The purpose of the present study was to investigate the effect of 22q11.2 deletion (22q11del) on infants with truncus arteriosus communis (TA) and interrupted aortic arch (IAA) undergoing operative correction during infancy. METHODS: We conducted a retrospective cohort study of all infants who had undergone operative correction of TA or IAA at the Children's Hospital of Philadelphia from 1995 to 2007, comparing the perioperative outcomes (hospital length of stay, intensive care, mechanical ventilation, risk of cardiac and noncardiac events, number of consultations, and number of discharge medications) by 22q11del status...

The abdominal electrocardiogram (ECG) provides a non-invasive method for monitoring the fetal cardiac activity in pregnant women. However, the temporal and frequency overlap between the fetal ECG (FECG), the maternal ECG (MECG) and noise results in a challenging source separation problem. This work seeks to compare temporal extraction methods for extracting the fetal signal and estimating fetal heart rate. A novel method for MECG cancelation using an echo state neural network (ESN) based filtering approach was compared with the least mean square (LMS), the recursive least square (RLS) adaptive filter and template subtraction (TS) techniques...

Although fetal echocardiography is a useful tool for earlier detection of congenital heart disease (CHD), no clear, evidence-based appropriate use criteria exist. This study aimed to determine those referral indications most predictive of CHD. A retrospective cohort study of fetal echocardiograms was conducted at a single tertiary care center. Binomial proportion tests were used to compare likelihoods of structural CHD detection based on primary indication with the general population prevalence of 0.8%. Fetal echocardiograms of 2,380 pregnancies were performed, with CHD detected in 29...

Electrocardiography is often advocated as a screening tool in children for hypertrophic cardiomyopathy (HC). We sought to establish an electrocardiographic screening tool to identify children with HC. We hypothesized that a pediatric-specific electrocardiographic criterion would perform better than the popular criteria used for screening children for left ventricular hypertrophy and HC. The earliest available electrocardiogram for children (n=108) with HC (ages 7 to 21 yrs) was reviewed. We sought to compare the diagnostic accuracy of 4 screening algorithms: (1) Sokolow-Lyon criterion (SV1+RV5/RV6>35 mm), (2) Cornell criterion (RaVL+SV3>28 mm in men, 20 mm in women), (3) total 12-lead voltage criterion (R wave to the nadir of Q/S wave>175 mm), and (4) pediatric-specific criterion (RaVL+SV2>23 mm)...
