Cardiac murmurs, most of which are harmless, are present in more than 50% of children. Good auscultation skills are required to prevent unnecessary referrals. The auscultation skills of a group of 21 pediatric residents were assessed. Based on their identification of key features such as S1, S2, timing, grade, location, quality of the murmur, and any extra sounds, residents were asked to make a clinical diagnosis. The overall diagnostic accuracy for all residents was 30% and improved with years of training. The average score for correctly identified key features was 46% with no significant improvement with year of training. Residents who had completed a cardiology rotation scored better than the others (41% vs 18% for correct diagnosis). Clinical auscultation skills of pediatric residents in our institution showed significant improvement with training, especially in the ability to recognize a harmless heart murmur.
The spectrum of presentation of pediatric myocarditis ranges from minor flu-like illness with chest pain to acute cardiogenic shock in a previously healthy child. A major change in the diagnostic evaluation of myocarditis is a shift in focus away from endomyocardial biopsy and histologic confirmation toward cardiac MRI for noninvasive diagnosis and prognostication of acute myocarditis. Cardiac MRI may be particularly useful in pediatric patients, considering the risks associated with biopsy in children. Some of the MRI characteristics seen in pediatric patients with acute myocarditis also may serve as predictors of outcome. The approach to managing myocarditis varies according to the severity of presentation; it is primarily supportive while spontaneous recovery of cardiac function is awaited. For subacute heart failure, the mainstay of therapy is still supportive management with oral heart failure medications such as angiotensin-converting enzyme inhibitors, beta-blockers, and diuretics. Acute myocarditis presenting with severe symptomatology, termed fulminant myocarditis, has a high recovery rate. Aggressive supportive care, including mechanical circulatory support, is indicated in fulminant myocarditis. With the increasing availability of and experience with paracorporeal pulsatile mechanical assist devices for children, more and more young patients are being bridged to transplantation or recovery. Despite promising results from several uncontrolled pediatric studies using immunosuppressive and/or immunomodulating therapy with intravenous gamma-globulin, the translation of these results into a recommended, routine therapy for pediatric myocarditis has been complicated by the high rate of spontaneous improvement of myocarditis with supportive care and the lack of demonstrable benefit for such therapies in blinded, randomized, placebo-controlled trials in adult myocarditis. Further clinical studies are necessary to define the possible utility of immunosuppressive, immunomodulatory, and antiviral therapy. Heart transplantation remains the final therapeutic option for children with myocarditis and intractable severe heart failure.
In this largest reported series of FVP in children, there is an unusually high association of FVP with complex CHDs, chromosomal anomalies, and hypertrophic cardiomyopathy. Any patient with such disorders and manifest preexcitation should be evaluated with a high index of suspicion for a FVP.
Background and ObjectivesSocioeconomic factors are associated with health outcomes and can affect postoperative length of stay after congenital heart disease (CHD) surgery. The hypothesis of this study is that patients from neighborhoods with a disadvantaged socioeconomic status (SES) have a prolonged length of hospital stay after CHD surgery.MethodsPre- and postoperative data were collected on patients who underwent CHD surgery at the University of Maryland Medical Center between 2011 and 2019. A neighborhood SES score was calculated for each patient using data from the United States Census Bureau and patients were grouped by high vs. low SES neighborhoods. The difference of patient length of stay (LOS) from the Society for Thoracic Surgeons median LOS for that surgery was the primary outcome measure. Linear regression was performed to examine the association between the difference from the median LOS and SES, as well as other third variables.ResultsThe difference from the median LOS was −4.8 vs. −2.2 days in high vs. low SES groups (p = 0.003). SES category was a significant predictor of LOS in unadjusted and adjusted regression analyses. There was a significant interaction between Norwood operation and SES—patients with a low neighborhood SES who underwent Norwood operation had a longer LOS, but there was no difference in LOS by SES in patients who underwent other operations.ConclusionsNeighborhood SES is a significant predictor of the LOS after congenital heart disease surgery. This effect was seen primarily in patients undergoing Norwood operation.
