A Multimodal AI Prediction Model for Complications After Transcatheter Closure of Perimembranous VSD in Children

An observational study in Congenital Heart Disease (CHD), Ventricular Septal Defects (VSD) and Cardiac Catheterization, sponsored by Xinhua Hospital, Shanghai Jiao Tong University School of Medicine. Recruiting at 1 site in China. Open to participants aged Up to 18 Years. Per ClinicalTrials.gov, last updated 2026-08-05.

Why
  1. The study's listed conditions name Heart Septal Defects, Ventricular, a narrower term within Heart Defects, Congenital.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The goal of this observational study is to develop and validate a multimodal artificial intelligence prediction model for treatment-related complications in children with perimembranous ventricular septal defect (pmVSD) undergoing transcatheter device closure. The main question it aims to answer is: Can an AI model that integrates demographics, laboratory results, electronic health record text, echocardiography reports, chest radiographs, and electrocardiogram accurately predict the risk of complications at the individual patient level? Data will be retrospectively collected from routine clinical care records of pediatric patients who underwent transcatheter closure for pmVSD. Deep learning methods will be used to extract features from text and images to train and validate the prediction model.

Study population

Children (18 years or younger) with echocardiography-confirmed perimembranous ventricular septal defect who underwent transcatheter device closure at Xinhua Hospital between January 1, 2015, and December 31, 2025, identified retrospectively from routine clinical care records.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age ≤ 18 years at the time of transcatheter procedure.
  • Diagnosis of perimembranous ventricular septal defect confirmed by echocardiography, and underwent transcatheter device closure at the study center.
  • Medical records sufficient to ascertain the primary outcome within the pre-specified follow-up window, and availability of minimum baseline clinical information required for model development/validation.

Exclusion criteria

Exclusion Criteria:

  • Ventricular septal defects not classified as perimembranous on echocardiography, including muscular, outlet, or inlet VSDs, as well as multiple or complex VSDs involving more than one septal region.
  • Presence of complex congenital heart disease or associated structural abnormalities requiring concomitant surgical repair (e.g., tetralogy of Fallot).
  • Prior surgical VSD repair or prior transcatheter VSD closure.

What researchers measure

Primary outcomes

  1. Composite Procedure-Related Complications After Transcatheter Closure of Perimembranous VSD

    Occurrence of a composite endpoint of procedure-related complications, including arrhythmia requiring treatment, new-onset or worsened valvular regurgitation, residual shunt requiring reintervention, and device embolization.

    Time frame: Up to 30 Days After Transcatheter Closure

Secondary outcomes

  1. Area Under the Precision-Recall Curve (AUCPR) for Complication Prediction

    The area under the precision-recall curve (AUCPR) of the model for predicting the primary composite procedure-related complication endpoint.

    Time frame: Up to 30 Days After Transcatheter Closure

  2. Sensitivity of the Model at a Pre-Specified Risk Threshold

    Sensitivity for predicting the primary composite procedure-related complication endpoint at a pre-specified probability (risk) threshold.

    Time frame: Up to 30 Days After Transcatheter Closure

  3. Positive Predictive Value (PPV) of the Model at a Pre-Specified Risk Threshold

    Positive predictive value (PPV) for predicting the primary composite procedure-related complication endpoint at the same pre-specified probability (risk) threshold.

    Time frame: Up to 30 Days After Transcatheter Closure

  4. Negative Predictive Value (NPV) of the Model at a Pre-Specified Risk Threshold

    Negative predictive value (NPV) for predicting the primary composite procedure-related complication endpoint at the same pre-specified probability (risk) threshold.

    Time frame: Up to 30 Days After Transcatheter Closure

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 5, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
