Adolescents with CHD require transition to specialised adult-centred care. Previous studies have shown that adolescents’ knowledge of their medical condition is correlated with transition readiness. Three-dimensional printed models of CHD have been used to educate medical trainees and patients, although no studies have focused on adolescents with CHD. This study investigates the feasibility of combining patient-specific, digital 3D heart models with tele-education interventions to improve the medical knowledge of adolescents with CHD.

Adolescent patients with CHD, aged between 13 and 18 years old, were enrolled and scheduled for a tele-education session. Patient-specific digital 3D heart models were created using images from clinically indicated cardiac magnetic resonance studies. The tele-education session was performed using commercially available, web-conferencing software (Zoom, Zoom Video Communications Inc.) and a customised software (Cardiac Review 3D, Indicated Inc.) incorporating an interactive display of the digital 3D heart model. Medical knowledge was assessed using pre- and post-session questionnaires that were scored by independent reviewers.

Twenty-two adolescents completed the study. The average age of patients was 16 years old (standard deviation 1.5 years) and 56% of patients identified as female. Patients had a variety of cardiac defects, including tetralogy of Fallot, transposition of great arteries, and coarctation of aorta. Post-intervention, adolescents’ medical knowledge of their cardiac defects and cardiac surgeries improved compared to pre-intervention (p < 0.01).

Combining patient-specific, digital 3D heart models with tele-education sessions can improve adolescents’ medical knowledge and may assist with transition to adult-centred care.

患有冠心病的青少年需要过渡到以成人为中心的专业护理。先前的研究表明，青少年对其健康状况的了解与过渡准备程度相关。CHD 的 3D 打印模型已被用于教育医学实习生和患者，尽管没有研究集中在患有 CHD 的青少年身上。本研究调查了将患者特定的数字 3D 心脏模型与远程教育干预相结合以提高患有 CHD 的青少年的医学知识的可行性。

招募年龄在 13 至 18 岁之间的青少年冠心病患者，并安排他们参加远程教育课程。使用来自临床指示的心脏磁共振研究的图像创建患者特定的数字 3D 心脏模型。远程教育会议使用市售的网络会议软件（Zoom，Zoom Video Communications Inc.）和包含数字 3D 心脏模型的交互式显示的定制软件（Cardiac Review 3D，Indicated Inc.）进行。使用由独立评审员评分的会前和会后问卷评估医学知识。

22 名青少年完成了这项研究。患者的平均年龄为 16 岁（标准差为 1.5 岁），56% 的患者被确定为女性。患者有多种心脏缺陷，包括法洛四联症、大动脉转位和主动脉缩窄。干预后，与干预前相比，青少年对其心脏缺陷和心脏手术的医学知识有所提高（p < 0.01）。

将特定患者的数字 3D 心脏模型与远程教育课程相结合，可以提高青少年的医学知识，并可能有助于过渡到以成人为中心的护理。
