# Bridging surgical gaps in congenital heart disease: results from 50 remote telementored procedures using a new national digital platform in Brazil

## TL;DR

A new digital platform in Brazil successfully enabled remote telementoring for 50 pediatric heart surgeries, improving access to specialized care in low-resource areas.

## Contribution

A national digital telementoring platform for pediatric congenital heart surgery was developed and validated in a multicenter study.

## Key findings

- 50 procedures were performed with 93% complete telementoring and no technical failures.
- 76% of surgical teams reported increased confidence and 92% preserved autonomy during procedures.
- The platform was highly accepted and showed significant educational and procedural benefits.

## Abstract

Despite advances in cardiovascular surgery, access to specialized care remains limited in low-resource regions. Telemedicine, which expanded significantly during the COVID-19 pandemic, offers a strategy to mitigate these disparities. The National Teleconference Platform (TAC) was developed to provide real-time, multidisciplinary telementoring for pediatric congenital heart surgery in remote areas.

This prospective, multicenter study assessed the feasibility, usability, and effectiveness of the TAC platform. The system integrated videoconferencing with Internet of Things (IoT) technologies, enabling synchronous audiovisual communication, real-time monitoring of surgical equipment, and interactive mentorship. Three Brazilian centers from the North, Northeast, and Southeast regions participated. Telementoring encompassed the entire surgical workflow, from anesthesia induction to postoperative debriefing, with data security compliant with national and international standards.

Between November 2022 and March 2025, 50 pediatric cardiac procedures were performed with complete telementoring in 93% of cases, and no technical failures occurred. Each operating room incorporated seven connected devices. User evaluations revealed high satisfaction: 76% of surgical teams reported increased confidence, 92% preserved autonomy throughout procedures, and all participants highlighted the substantial educational value of the platform.

The TAC platform is feasible, effective, and well-accepted for providing multidisciplinary surgical guidance. It optimizes procedural performance, enhances surgical care, and demonstrates significant potential to expand access to specialized healthcare in resource-limited settings.
