Objectives: Pediatric cardiology has an expanding role in fetal and pediatric screening. The aims of this study were to observe how district hospitals use a pediatric telecardiology service, and to compare the costs and outcomes of patients referred to specialists by means of this service or conventionally.Methods: A telemedicine service was set up between a pediatric cardiac center in London and four district hospitals for referrals of second trimester women, newborn babies, and older children. Clinicians in each hospital decided on the role for their service. Clinical events were audited prospectively and costed, and patient surveys were conducted.Results: The hospitals differed in their selection of patient groups for the service. In all, 117 telemedicine patients were compared with 387 patients seen in London or in outreach clinics. Patients selected for telemedicine were generally healthier. For all patients, the mean cost for the initial consultation was £411 for tele-referrals and £277 for conventional referrals, a nonsignificant difference. Teleconsultations for women and children were significantly more expensive because of technology costs, whereas for babies, ambulance transfers were much more costly. After 6-months follow-up, the difference between referral methods for all patients was nonsignificant (telemedicine, £3,350; conventional referrals, £2,172), and nonsignificant within the patient groups.Conclusions: Telemedicine was perceived by cardiologists, district clinicians, and families as reliable and efficient. The equivocal 6-month cost results indicate that investment in the technology is warranted to enhance pediatric and perinatal cardiology services. [ABSTRACT FROM AUTHOR]

To determine the frequency of reversal of transfusional gradient and phenotype in a large cohort of prospectively studied cases of twin–twin transfusion syndrome (TTTS) and seek evidence of clinical or placental anastomotic associations. Consecutive cases of TTTS seen over an eight-year period with serial documentation of ultrasonic growth, liquor volume and fetal and placental Doppler studies were reviewed. Postnatal injection studies were inspected. Reversal of TTTS occurred in 5 of 96 affected pregnancies (5%). Two of the five cases had underlying aneuploidy or genetic syndrome, higher than the 2% frequency found in cases without reversal of TTTS (p < 0.05). Placental anastomotic configurations provided no consistent explanation for reversal of phenotype. This study documents the frequency of reversal of the direction of TTTS, and suggests that it is a heterogeneous condition. Reversal of donor–recipient phenotype may be explained by haemodynamic changes secondary to underlying aneuploidy/genetic syndromes, to the presence of multiple anastomoses in either direction or following laser ablation. This series together with previous case reports argues for a high level of suspicion for underlying aneuploidy, genetic syndrome or structural defects where there is reversal of the donor–recipient phenotype.
