Repair of truncus arteriosus in neonates with the use of a valveless conduit.

Each of seven infants 1 to 9 days old and weighing 2.1 to 3.3 kg with truncus arteriosus underwent repair of their defects with a right ventricular-to-pulmonary artery valveless conduit. Congestive heart failure and cyanosis were present before surgery in each. Five patients survived surgery and one of these subsequently died. Comparison between preoperative hemodynamics of the survivors and nonsurvivors disclosed similar peak systolic pulmonary arterial and aortic pressures, and pulmonary (Rp) or systemic resistance (Rs) in the groups. However, the mean Rp/Rs ratio in survivors (0.15) was significantly less than in nonsurvivors (0.63) (p = .001). The four remaining survivors are asymptomatic 7 months to 5.5 years after operation. Postoperative cardiac catheterization in three patients disclosed proximal conduit obstruction of 10 to 20 mm Hg in each, distal conduit obstruction of 35 mm Hg in two, and mild truncal valve stenosis and moderate truncal regurgitation in one each. We recommend the use of a valveless conduit for the symptomatic neonate with truncus arteriosus and a low Rp/Rs ratio (less than or equal to 0.03).

Use of videotape in the preparation of children for cardiac catheterization.

To help children with congenital heart disease, and their parents, cope with the stress of hospitalization for cardiac catheterization, a videotape was developed entitled "Leonard Z. Lion Presents ... Learning About Your Heart Catheterization." Fifty-three patients with congenital heart disease, 3 to 12 years of age, were randomly assigned to experimental (N = 31) or control (N = 22) groups. Each viewed the catheterization videotape or an unrelated control videotape before cardiac catheterization. The child's knowledge, anxiety, and adjustment during and after hospitalization for catheterization were evaluated. The experimental group displayed a significantly greater knowledge of events and sensations experienced during hospitalization than controls (P less than .0001). Children in the experimental group tended to sleep more during the catheterization procedure (P = .05) and when awake to ask more questions (P = .02). After discharge, the experimental group also tended to demonstrate more independent behavior. We conclude that viewing this videotape on heart catheterization helped children with congenital heart disease to cope with the stress of hospitalization for the procedure.

Primary preventive health care in children with heart disease.

In order to evaluate the preventive health care practices in children with heart disease, 499 families were surveyed in outpatient settings. Data were collected on 215 children with heart disease and 284 control children without known chronic illness. There was no significant difference between the groups in the type of primary physician utilized or frequency of visits to the primary care physician. Immunizations were incomplete in 32.7% of the children with heart disease compared to only 2.5% in the control group (P less than 0.0001). Among the children over 3 years of age with heart disease, 29% had not received routine dental care within the past year compared with 23.4% in the controls (P = NS). The parents of children with heart disease were found to pay less money out-of-pocket for their child's health care than the parents of control children (P less than 0.0001). The data suggest that important aspects of primary health care were neglected in a large group of children with heart disease and that cost was not a major cause for the inadequate preventive care delivery. An educational program directed at health care professionals and parents is proposed.

Health education needs of adolescents with congenital heart disease.

Self-concept, health beliefs, health behaviors, health information sources, and perceived health information needs were assessed in 90 patients with congenital heart disease and 54 peers without chronic illness, ages 13 to 22 years. Data revealed that patients with congenital heart disease did not differ from their healthy counterparts in overall self-concept, health beliefs, use of preventive health services, and sources of health information. Patients with congenital heart disease reported greater perceived stress in comparison to peers. Significantly more patients with heart disease needed information regarding pregnancy and contraception, and older cardiac subjects were less likely to be sexually active. For these patients who currently seem to rely largely on peers for some critical health information, sensitive and comprehensive counseling by health professionals is imperative.

The pediatric nurse practitioner as case manager in the delivery of services to children with heart disease.

Today's health care environment prompted implementation of a case management model by pediatric nurse practitioner clinical nurse specialists to promote the organization of resources for optimal care of children with heart disease. Evaluation of this pilot program suggests that achievement of expected outcomes within an appropriate length of stay was facilitated, that parents were ready for discharge, and that readmissions were infrequent. In addition, patient and system variances resulting in delay of discharge and discharge preparation needs were identified. The pediatric nurse practitioner as case manager may have a significant impact on the quality and cost of care for hospitalized children.

Family stress after pediatric heart transplantation.

Parents of ten children who underwent cardiac transplantation at the authors' institution participated in this study to evaluate the effect of heart transplantation on the family. Parents completed the Hymovich Chronicity Impact and Coping Instrument (CICI) and/or the Feetham Family Function Survey (FFFS) 3 to 24 months (mean, 8.4 months) after the transplant. Results indicate that parents face significant psychological and social stresses after their child's heart transplantation related to (1) the uncertainty of the child's future health and well-being, (2) role strain, (3) social isolation, and (4) financial burdens. Recommendations for nursing practice are suggested.
