Parent-Reported Symptoms and Perceived Effectiveness of Treatment in Children Hospitalized with Advanced Heart Disease.

OBJECTIVE: To characterize parent-reported symptom burden and effectiveness of symptom management in children hospitalized with advanced heart disease. STUDY DESIGN: Prospective survey study of 161 parents whose child was admitted to a single institution with advanced heart disease between March 2018 and February 2019 using the Survey about Caring for Children with Heart Disease. RESULTS: Of the 161 patients, 54% were under 2 years old with a diagnosis of single ventricle physiology (39%), pulmonary hypertension (12%), and other congenital heart disease (28%). Over one-half (56%) of parents reported that their child was experiencing a high degree ("a great deal"/"a lot") of symptoms. The most frequently reported symptoms were pain (68%), fatigue (63%), and breathing difficulties (60%). Of the symptoms that were treated, parents perceived successful treatment to be least likely for their child's sleep disturbance (24%), depression (29%), and fatigue (35%). Parents who reported their child's functional status as New York Heart Association class III/IV were more likely to report that their child was experiencing "a great deal" of symptoms, compared with those who reported class I/II (51% vs 19%, P < .001). Parents who reported their child was experiencing a high degree of suffering from fatigue were also more likely to report a high symptom burden (P < .001). CONCLUSIONS: Parents of children with advanced heart disease reported high symptom burden with a broad spectrum of symptoms. Parents reported fatigue and psychiatric symptoms frequently and rarely reported treatment as successful. Parents' view of their child's symptom burden was concordant with their perception of their child's functional status.

Comparison of tissue Doppler imaging and conventional echocardiography to discriminate rejection from non-rejection after pediatric heart transplantation.

TDI is considered superior to conventional echocardiography for detecting changes in graft function during rejection in adults but has not demonstrated after pediatric OHT. We retrospectively analyzed echocardiograms performed within 24 hours of biopsy in 122 recipients with median age of 8.7 years. Using biopsy findings as the gold standard, we compared paired rejection and non-rejection echocardiograms using each patient as their own control. We included pairs of LV dimensions, FS, volumes, mass, mass/volume, sphericity, wall stress, SSI, SVI, and TDI velocities in this comparison. C-statistic was used to assess discrimination for individual echo variables and combinations of variables. Overall, 647 non-rejection and 24 rejection biopsy-echo pairs were identified. There was a significant decline in TDI velocities and their Z-scores during rejection but not in conventional variables (P ≤ .005). The variable that best discriminated rejection from non-rejection was LV S', with C-statistic = 0.93. Conventional echo variables performed less well with C-statistic range 0.65-0.67 for LV EF, shortening fraction, and mass. TDI is superior to conventional echocardiography measures for discriminating rejection from non-rejection. The use of newer non-invasive parameters to detect myocardial dysfunction and shifting the paradigm of rejection surveillance to detection of non-rejection together provide a promising approach to reducing the need for biopsy in pediatric heart recipients.
