Evaluating the validity and reliability of Youtube videos on ‘heart anatomy’ for anatomy education

The anatomical structure of the heart is complex, demanding detailed understanding for effective clinical interpretation and medical education. YouTube is frequently used as a learning tool for anatomy, but the quality and accuracy of its content are inconsistent. This study systematically evaluated 58 YouTube videos on heart anatomy using the Brave browser in incognito mode. Video characteristics (duration, resolution), engagement metrics (views, likes), and content quality were assessed using the Global Quality Scale (GQS), Journal of the American Medical Association (JAMA) Score, modified DISCERN, and an Anatomical Content Score. Statistical analyses were conducted using Jamovi 2.6.24.0. Results indicated that 44.8% of videos were created by anatomists, and 75.9% involved healthcare professionals. The most common format was animation (29.3%), while cadaver-based content was limited (12.1%). Videos presented by physicians achieved significantly higher GQS and modified DISCERN scores. Longer videos correlated with greater educational quality and user engagement. High-resolution videos showed higher view rates and Video Power Index, though resolution did not significantly affect quality scores. Overall, YouTube provides moderate-quality educational content on heart anatomy. Enhancing author transparency, referencing, and the use of cadaveric material may improve its value as a reliable educational resource.
