Referring Provider Opinions of Pediatric Cardiology Evaluations Performed by Nurse Practitioners.

In the setting of physician shortages, nurse practitioner (NP) roles have evolved, with increasing independence across most healthcare settings. We sought to characterize referring clinician perceptions of NP-performed outpatient pediatric cardiology consultations. We electronically distributed to pediatric and family medicine physicians and NPs in Arkansas our 11-item survey assessing the acceptability of pediatric cardiology consultations being completed by an NP under varying circumstances. Circumstances included seven common referral indications, and the scale offered five answer choices ranging from "definitely unacceptable" to "definitely acceptable". A total of 292 of 1756 (16.6% response rate) referring clinicians responded to the survey. Overall, 57% of responses indicated that NP-completed pediatric cardiology evaluations were either definitely or probably unacceptable. Acceptability was varied by referral indication and referring clinician characteristics. Unacceptability of NP-completed pediatric cardiology evaluations was greatest among family medicine physicians (81%), pediatricians (66%), and clinicians working in solo or two-physician practices (77%) or community hospitals/clinics (71%). If NP evaluation of a murmur included required review with a cardiologist, the unacceptability rate dropped from 50 to 24% (p < 0.0001). Unacceptability was higher in physicians who do not work with NPs (69%) compared to those who do (60%) (pp < 0.0001). Many referring physicians were willing to send patients ≥ 100 miles to ensure evaluation by a pediatric cardiologist. Most referring physicians find pediatric cardiology evaluations performed by NPs to be unacceptable. Requisite review with a cardiologist improved acceptability of NP evaluations. Many referring physicians would send patients much farther to guarantee evaluation by a cardiologist.

mRNA Coronavirus Disease 2019 Vaccine-Associated Myopericarditis in Adolescents: A Survey Study.

Only one adolescent with life-threatening complications was reported, with no deaths at any of the participating institutions.

Paediatrician's guide to post-operative care for functionally univentricular CHD: a review.

IMPORTANCE: Single ventricle CHD affects about 5 out of 100,000 newborns, resulting in complex anatomy often requiring multiple, staged palliative surgeries. Paediatricians are an essential part of the team that cares for children with single ventricle CHD. These patients often encounter their paediatrician first when a complication arises, so it is critical to ensure the paediatrician is knowledgeable of these issues to provide optimal care. OBSERVATIONS: We reviewed the subtypes of single ventricle heart disease and the various palliative surgeries these patients undergo. We then searched the literature to detail the general paediatrician's approach to single ventricle patients at different stages of surgical palliation. CONCLUSIONS AND RELEVANCE: Single ventricle patients undergo staged palliation that drastically changes physiology after each intervention. Coordinated care between their paediatrician and cardiologist is requisite to provide excellent care. This review highlights what to expect when these patients are seen by their paediatrician for either well child visits or additional visits for parental or patient concern.

Paediatrician's guide to post-operative care for biventricular CHD: a review.

IMPORTANCE: Paediatricians play an integral role in the lifelong care of children with CHD, many of whom will undergo cardiac surgery. There is a paucity of literature for the paediatrician regarding the post-operative care of such patients. OBSERVATIONS: The aim of this manuscript is to summarise essential principles and pertinent lesion-specific context for the care of patients who have undergone surgery or intervention resulting in a biventricular circulation. CONCLUSIONS AND RELEVANCE: Familiarity with common issues following cardiac surgery or intervention, as well as key details regarding specific lesions and surgeries, will aid the paediatrician in providing optimal care for these patients.

Impact of Clinician Engagement on Implementation of the Pediatric Echocardiography Appropriate Use Criteria.

We sought to determine whether awareness of the pediatric appropriate use criteria (AUC) affected transthoracic echocardiogram (TTE) ordering by cardiologists; evaluate for differences in classification of an encounter's AUC clinical scenario by investigator chart review compared with clinicians at the time of the encounter; and assess TTE yield by appropriateness rating. AUC clinical scenario(s) were assigned to patients without prior TTE by investigator chart review of visits in 2014 (n = 209) and 2016 (n = 199), and by clinician classification in 2016 (n = 671). Investigators documented TTE utilization and findings. Between 2014 and 2016, TTE utilization decreased from 54 to 33% (p < 0.001) of "rarely appropriate" (R) encounters, resulting in a decrease in overall TTE utilization from 73 to 55% of encounters (p < 0.001). There was only moderate agreement of AUC appropriateness by investigator chart review and clinician classification (κ = 0.533, p < 0.001). Abnormal TTE findings were detected in 18.7% of R encounters, with 21 of 24 abnormalities in infants younger than 4 months presenting with murmur. A decrease in TTE utilization for R encounters may represent a change in practice from increased awareness of the AUC. AUC scenario classification by clinicians at the time of the encounter could be superior to chart review. TTE abnormalities may be missed in infants younger than 4 months of age when evaluated for murmurs with the AUC.

Respiratory motor function in individuals with centronuclear myopathies.

UNLABELLED: I NTRODUCTION: Individuals with X-linked myotubular myopathy (XLMTM) and other centronuclear myopathies (CNMs) frequently have profound respiratory insufficiency that requires support early in life. Still, few quantitative data exist to characterize respiratory motor function in CNM. METHODS: We evaluated the reliance upon mechanical ventilation (MV), ventilatory kinematics, unassisted tidal volumes, and maximal respiratory pressures in 14 individuals with CNMs, including 10 boys with XLMTM. RESULTS: Thirteen participants required full-time, invasive MV. Maximal inspiratory pressures were higher in subjects who breathed unsupported at least 1 hour/day as compared with 24-hour MV users [33.7 (11.9-42.3) vs. 8.4 (6.0-10.9) cm H(2)O, P < 0.05]. Years of MV dependence correlated significantly with MEP (r = -0.715, P < 0.01). CONCLUSIONS: Respiratory function in CNMs may be related to deconditioning from prolonged MV and/or differences in residual respiratory muscle strength. Results from this study may assist in evaluating severe respiratory insufficiency in neuromuscular clinical care and research.

Care of the Fetus With Congenital Cardiovascular Disease: From Diagnosis to Delivery.

BACKGROUND: The majority of congenital cardiovascular disease including structural cardiac defects, abnormalities in cardiac function, and rhythm disturbances can be identified prenatally using screening obstetrical ultrasound with referral for fetal echocardiogram when indicated. METHODS: Diagnosis of congenital heart disease in the fetus should prompt assessment for extracardiac abnormalities and associated genetic abnormalities once maternal consent is obtained. Pediatric cardiologists, in conjunction with maternal-fetal medicine, neonatology, and cardiothoracic surgery subspecialists, should counsel families about the details of the congenital heart defect as well as prenatal and postnatal management. RESULTS: Prenatal diagnosis often leads to increased maternal depression and anxiety; however, it decreases morbidity and mortality for many congenital heart defects by allowing clinicians the opportunity to optimize prenatal care and plan delivery based on the specific lesion. Changes in prenatal care can include more frequent assessments through the remainder of the pregnancy, maternal medication administration, or, in selected cases, in utero cardiac catheter intervention or surgical procedures to optimize postnatal outcomes. Delivery planning may include changing the location, timing or mode of delivery to ensure that the neonate is delivered in the most appropriate hospital setting with the required level of hospital staff for immediate postnatal stabilization. CONCLUSIONS: Based on the specific congenital heart defect, prenatal echocardiogram assessment in late gestation can often aid in predicting the severity of postnatal instability and guide the medical or interventional level of care needed for immediate postnatal intervention to optimize the transition to postnatal circulation.

Variable Presentation of COVID-19 in Pediatric Patients.

Infection by SARS-CoV-2 has led to disease referred to as coronavirus disease 2019 which, in children has been described as of multisystem inflammatory syndrome in children. Our experience demonstrates 2 distinct presentations of this syndrome which have different clinical courses and may have differing long-term outcomes.

Advanced imaging improves detection of baffle leaks and stenoses after atrial switch compared with transthoracic echocardiography.

Current guidelines for adults with atrial switch repair recommend baseline cardiovascular magnetic resonance (CMR) for assessment of ventricular size and function, systemic and venous baffle obstruction and leaks, and valvular function. It also recommends transthoracic echocardiography (TTE) for outpatient follow up. Many such patients with implanted cardiac devices may need cardiac computed tomography (CCT) when CMR is not feasible. This study reviews and compares CMR, transesophageal echocardiography (TEE), CCT, cardiac catheterization with angiography and TTE in detection of baffle problems in patients after atrial switch operation. The medical records of patients who had at least one imaging study performed after atrial switch operation at our center from 2010 to 2020 were retrospectively reviewed. Results are reported as descriptive statistics for demographics and imaging findings. The principal outcome measure was detection of baffle leak and/or baffle stenosis. Fifty-seven patients had at least one cardiac imaging study after atrial switch operation (36 Senning and 21 Mustard operations) during the study period. Nearly 33% (19/57) had baffle complications of stenosis and/or baffle leaks identified. All 57 patients had TTE performed but baffle problems were noted by TTE in only 8 (14%) patients (7 baffle stenosis and 1 baffle leak). Of the 49 patients without known baffle problems by TTE, 24 had advanced imaging (TEE/CCT/CMR/angiography). Advanced imaging identified baffle problems in nearly half (11/24, 46%) of them (7 baffle leaks and 4 baffle stenosis). Baffle problems were present in (8/23) patients with transvenous cardiac devices. Baffle complications are common after atrial switch operations and in our study occur in 1/3rd of the patients. However, TTE is not sensitive enough to recognize these complications. Advanced imaging for detection of baffle complications should be considered in all patients after atrial switch operation.

An anthropomorphic beating heart phantom for cardiac x-ray CT imaging evaluation.

The current work describes an anthropomorphic beating heart phantom constructed as a tool for the assessment of technological advances in cardiac x-ray computed tomography (CT). The phantom is comprised of a thorax, a compressor system, an ECG system, a beating heart with tortuous coronary arteries, and the option to add or remove pathologies such as aberrant beats, stents, and plaques. Initial trials with the phantom have shown its utility to assess temporal resolution, spatial resolution, radiation dose, iodine contrast, stents, and plaques.

Implementation of a statewide, multisite fetal tele-echocardiography program: evaluation of more than 1100 fetuses over 9 years.

OBJECTIVES: We sought to describe the implementation and effectiveness of a statewide fetal tele-echocardiography program serving a resource-limited population. STUDY DESIGN: In 2009, our heart center established six satellite clinics for fetal tele-echocardiography around the state. We retrospectively reviewed all fetal tele-echocardiograms performed through 2018. Yearly statewide prenatal detection rates of operable congenital heart disease were queried from the Society of Thoracic Surgeons database. RESULT: In 1164 fetuses, fetal tele-echocardiography identified all types of congenital heart disease, with a sensitivity of 74% and specificity of 97%. For the detection of ductal-dependent congenital heart disease, fetal tele-echocardiography was 100% sensitive and specific. Between 2009 and 2018, annual statewide prenatal detection rates of congenital heart disease requiring heart surgery in the first 6 months of life rose by 159% (17-44%; R2 = 0.88, p < 0.01). CONCLUSIONS: The present study provides a framework for an effective, large-scale fetal tele-echocardiography program.

Neonatal ventricular fibrillation and an elusive ALCAPA: things are not always as they seem.

An anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital cardiac condition that typically presents with poor feeding and failure to thrive from progressive myocardial ischaemia. Previous reports of ALCAPA presenting with ventricular fibrillation (VF) have suggested a causative relationship. In this case, we present a neonate with VF without apparent cause after an extensive evaluation. Following implantable cardioverter-defibrillator placement for presumed idiopathic VF, at which time she also underwent surgical ligation of a patent ductus arteriosus (PDA), the neonate developed haemodynamic instability that ultimately was found to be due to ALCAPA. Numerous echocardiograms had missed the ALCAPA in the setting of mildly elevated pulmonary artery pressure. We discuss the limitations of current ultrasound technology in diagnosing ALCAPA in the setting of pulmonary hypertension and explain why the relationship between this patient's diagnosis of ALCAPA and her episode of VF is not clearly causative.

Segmentation of 4D cardiac images: investigation on statistical shape models.

The purpose of this research was two-fold: (1) to investigate the properties of statistical shape models constructed from manually segmented cardiac ventricular chambers to confirm the validity of an automatic 4-dimensional (4D) segmentation model that uses gradient vector flow (GVF) images of the original data and (2) to develop software to further automate the steps necessary in active shape model (ASM) training. These goals were achieved by first constructing ASMs from manually segmented ventricular models by allowing the user to cite entire datasets for processing using a GVF-based landmarking procedure and principal component analysis (PCA) to construct the statistical shape model. The statistical shape model of one dataset was used to regulate the segmentation of another dataset according to its GVF, and these results were then analyzed and found to accurately represent the original cardiac data when compared to the manual segmentation results as the golden standard.
