3D Printed Advanced Cardiac Models for Transseptal Puncture, Cardiac Ablation, and Cardiac Tamponade Simulation Training

Overview

The objective of this study is to develop advanced cardiac models using 3D printing technology for teaching complex cardiology procedures such as (1) transseptal puncture, (2) cardiac ablation, and (3) ultrasound scanning and drainage of cardiac tamponade. By implementing this study, the investigators aim to transform the teaching methods for cardiology students at our hospital.

Background： The standard methodology for education in medicine, particularly in cardiology, still follows the apprenticeship model, where trainees observe, gradually take over, and practice under supervision until they can independently perform procedures. The traditional pedagogical strategy for complex medical procedures, like cardiac catheterization, emphasizes the "see one, do one, teach one" doctrine. Studies have revealed the superior efficacy of 3D printing in medical education, particularly in enhancing learning skills and knowledge among medical students. The demand for 3D printed models in medical education is increasing continuously. Study Design： This study is a single-center, pilot, prospective, randomized controlled educational trial. Methods： The trial will be conducted in the Department of Cardiovascular Medicine at Fu Jen Catholic University Hospital. The investigators plan to enroll 50 participants, who will be randomly assigned to either the 3D model training group (n=25) or the conventional curriculum group (n=25) in a 1:1 ratio. All participants will undergo pre- and post-training assessments, including a knowledge test (structured written questionnaire), an attitude assessment (semi-structured satisfaction questionnaire), and a skills evaluation (direct observation of procedural skills, DOPS). Effect： The investigators anticipate the development of a set of advanced 3D cardiac models for teaching cardiology procedures. It is expected that combining classroom learning with the viewing and interactive practice of 3D printed models will significantly improve the learning outcomes of the trainees. Key words： Clinical simulation-based education, advanced cardiology procedures, transseptal puncture, cardiac ablation, cardiac tamponade.
