Fetal and Neonatal Magnetophysiology
NCT01903564 · View on ClinicalTrials.gov ↗
Study Summary
Fetal research and clinical practice has been hampered by a lack of suitable investigational techniques. Currently, ultrasound is the only widely used method of studying fetal anatomy and physiology, but it has significant limitations for assessment of cardiac rhythm. The proposed study will allow us to investigate fetal magnetocardiography (fMCG) as a new tool for the study of normal and abnormal fetal heart rate and rhythm, with a goal of demonstrating probable benefit from use of the device in patients with serious fetal arrhythmia. We propose a study that will last 1-2 years and will provide data to aid in assessing the safety and effectiveness of fMCG for diagnosis and management of patients with abnormal fetal heart rate and rhythm. We hope that the data from the study will support a Humanitarian Device Exemption (HDE) application for the subject device. The safety and efficacy study designs are described below. High-risk subjects will undergo echocardiography as part of their routine clinical management, and our results will be compared to the echocardiography results, as well as with postnatal ECG, when available. (Since many arrhythmias resolve prior to birth, either due to resolution of disease or due to treatment, only a limited number of diseases allow postnatal comparison). For rhythms that persist after birth, the diagnostic utility of fMCG and echocardiography will be assessed by computing the sensitivity (Sn) and specificity (Sp) relative to postnatal ECG for the following prenatal modalities: (i) the fMCG, (ii) the original (referral) echo, (iii) if available, the in-lab echocardiogram at the time of the fMCG study. Secondary endpoints will assess changes in diagnosis and in clinical management due to the additional information provided by fMCG, compared to the information provided by echocardiography alone.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01903564
The ClinicalTrials.gov registry entry for NCT01903564 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 39 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Wisconsin, Madison, which has 943 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Long QT Syndrome appearing as the primary indexed condition, and to 3 interventions — of which magnetocardiography is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01903564 reports 1 study location spanning 1 distinct geographic area — top geographies include Wisconsin. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
