Abstract

OBJECTIVE: To assess whether the spatio-temporal image correlation (STIC) acquisition technique can be taught to a general obstetrician by e-mail; whether STIC volume datasets can be transmitted over the Internet; and whether STIC volume datasets analyzed offline at a remote setting can be used to confirm or exclude major cardiac defects (TELE-STIC). METHODS: This was a prospective study involving 50 pregnant women with gestational ages ranging between 20 and 36 weeks. These patients were selected by two general obstetricians (operators) working in geographically remote areas of Chile. Although both obstetricians were users of equipment capable of four-dimensional (4D) ultrasound with STIC, they lacked skill in the performance of fetal cardiac examination. A dedicated web disk was created to upload the acquired volume datasets using an Internet broadband connection. Offline analysis was performed by a single investigator experienced in fetal echocardiography (the administrator). RESULTS: A telemedicine link via the Internet was possible in all cases. Seventy-seven volume datasets were sent to the web server. A complete cardiac examination according to set criteria was achieved by the administrator in 86% of the cases scanned by one operator and 95% of the cases scanned by the other operator. Three patients had cardiac defects confirmed postnatally, two fetuses had extracardiac anomalies and one fetus had a suspected cardiac defect unconfirmed by second-opinion TELE-STIC. There were two isolated major congenital heart defects. Both patients were given advice by e-mail and teleconference using a web camera about the likely outcome and benefits of scheduling in utero transport to a tertiary care center. CONCLUSIONS: STIC volumes can be obtained by operators inexperienced in fetal echocardiography, transmitted via the Internet, and their analysis enables recognition of most of the structures and views necessary to assess fetal cardiac anatomy. The preliminary use of TELE-STIC allowed us to demonstrate that some intracardiac anomalies can be ruled out and others confirmed, allowing perinatal management to be tailored accordingly.

  • These changes include earlier treatment and appropriate escalation of care to tertiary centers.

    “These changes include earlier treatment and appropriate escalation of care to tertiary centers (37).”

    From Tele-Ultrasound in Resource-Limited Settings: A Systematic Review (2019) · cites this paper as [37]

    The Results describe advice to arrange in utero transport to a tertiary care center for two affected fetuses, and the Discussion says TELE-STIC could enable maternal transfer to a specialist center for delivery. The paper also reports neonatal interventions, but it does not establish that treatment occurred earlier than it otherwise would have. (LLM, conf=0.84)

  • Tele-ultrasound has demonstrated success in producing high quality, diagnostically significant images.

    “Tele-ultrasound has demonstrated success in producing high quality, diagnostically significant images which alter management, decrease time to treatment, and provide more cost-effective care, especially when coupled with supporting data such as electrocardiogram, chest radiography, laboratory results, and clinical history (29, 30, 33, 35, 37, 48).”
  • Tele-ultrasound alters management.

  • Image acquisition can be taught from a distance via the internet and a telemedicine platform is reliably able to transmit high quality images.

    “Image acquisition can be taught from a distance via the internet and a telemedicine platform is reliably able to transmit high quality images (29, 34, 37, 38).”
  • Ultrasound training programs have taught non-experts either to independently perform obstetric ultrasounds to screen for high-risk pregnancies or to utilize tele-ultrasound.

    “In an attempt to overcome such challenges, ultrasound training programs have taught non-experts either to independently perform obstetric ultrasounds to screen for high-risk pregnancies (52–55) or to utilize tele-ultrasound (29, 34, 37, 38).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
