The purpose of this prospective multi-center cross-sectional study was to identify key biopsychosocial factors that impact quality of life (QOL) of youth with congenital heart disease (CHD). Patient-parent pairs were recruited at a regular hospital follow-up visit. Patient- and parent-proxy-reported QOL were assessed using the Pediatric Cardiac Quality of Life Inventory (PCQLI). Wallander's and Varni's disability-stress coping model guided factor selection, which included disease factors, educational impairment, psychosocial stress, child psychological and parent/family factors. Measures utilized for these factors included the Pediatric Inventory for Parents, Self-Perception Profile for Children/Adolescents, Child Behavior Checklist, Revised Children's Manifest Anxiety Scale, Child PTSD Symptom Scale, State-Trait Anxiety Inventory, and Posttraumatic Diagnostic Scale. Ordinary least squares regression was applied to test the theoretical model, with backwards stepwise elimination process. The models accounted for a substantial amount of variance in QOL (Patient-reported PCQLI R = 0.58, p< 0.001; Parent-proxy-reported PCQLI R = 0.60, p< 0.001). For patient-reported QOL, disease factors, educational impairment, poor self-esteem, anxiety, patient posttraumatic stress, and parent posttraumatic stress were associated with lower QOL. For parent-proxy-report QOL, disease factors, educational impairment, greater parental medical stress, poorer child self-esteem, more child internalizing problems, and parent posttraumatic stress were associated with lower QOL. The results highlight that biopsychosocial factors account for over half the variance in QOL in CHD survivors. Assessing and treating psychological issues in the child and the parent may have a significant positive impact on QOL.

In adults with hypertrophic cardiomyopathy, the annual mortality rate from sudden death is 2 to 3%, and the finding of nonsustained ventricular tachycardia during electrocardiographic (ECG) monitoring provides a marker of the patient who is at increased risk. In the young, the annual mortality rate from sudden death is even higher, approximately 6%, but the prognostic significance of arrhythmia is unknown. To determine the prevalence of arrhythmia and its relation to prognosis, 2 days of ECG monitoring was performed in 6 infants, 14 children and 33 adolescents with hypertrophic cardiomyopathy receiving no cardioactive medications. An additional 1 to 9 days (median 2) of monitoring was performed in 29 patients. All patients had sinus rhythm; 4 adolescents had episodes of paroxysmal supraventricular tachycardia, a child with the Wolff-Parkinson-White syndrome had symptomatic reentrant atrioventricular tachycardia and 5 adolescents had asymptomatic nonsustained ventricular tachycardia. During follow-up of 1 week to 7 years (median 3 years), five patients died suddenly and two had successful resuscitation from out-of-hospital ventricular fibrillation; none of these seven patients had ventricular arrhythmias during 2 to 7 days (median 3) of ECG monitoring. The two patients with ventricular fibrillation, the five with ventricular tachycardia, the one with Wolff-Parkinson-White syndrome and the seven with recurrent syncope or adverse family history, or both, received low dose amiodarone. None of these "high risk" patients died during 6 months to 6 years (median 3 years) of follow-up.(ABSTRACT TRUNCATED AT 250 WORDS)

Manually linking data sources produced hospital-specific and lesion-specific prenatal mCHD detection rates. More granular, rather than aggregate, data provides meaningful feedback to improve screening performance. Automatic maternal and infant record linkage on a national scale, requires verified, prospective maternity audit and integration of health information systems.
