This study aims to compare the performance of electrophysiology fellows in transseptal catheterization (TSP-C) after conventional (Conv-T) or simulator training (Sim-T).
Current training for TSP-C, an increasingly used procedure, relies on performance on patients with supervision by an experienced operator. Virtual reality, a new training option, could improve post-training performance.
Fellows inexperienced in TSP-C were enrolled and randomly assigned to Conv-T or Sim-T. The post-training performance of each fellow was evaluated and scored in 3 consecutive patient-based procedures by an experienced operator blinded to the fellow's training assignment.
Fourteen fellows were randomized to Conv-T (n = 7) or to Sim-T (n = 7) and, after training, performed 42 TSP-Cs independently. Training time was significantly longer for Conv-T than for Sim-T (median 30 days vs. 4 days; p = 0.0175). The Conv-T fellows had significantly lower post-training performance scores (median 68 vs. 95; p = 0.0001) and a higher number of recurrent errors (median 3 vs. 0; p = 0.0006) when compared with Sim-T fellows.
The TSP-C training with virtual reality results in shorter training times and superior post-training performance.
本研究旨在比较传统培训（Conv-T）或模拟器培训（Sim-T）后电生理学研究员在行经房间隔穿刺术（TSP-C）方面的表现。
目前，TSP-C 作为一种越来越常用的手术，其培训依赖于在有经验操作者监督下对患者的操作。虚拟现实，一种新的培训选择，可能会提高培训后的表现。
招募对 TSP-C 经验不足的研究员，并随机分配至 Conv-T 或 Sim-T 组。由一位经验丰富的操作者对每位研究员进行 3 次连续的基于患者的手术，对其术后表现进行评估和评分，该操作者对研究员的培训分配情况并不知情。
共有 14 名研究员被随机分配至 Conv-T（n = 7）或 Sim-T（n = 7）组，培训后，他们独立完成了 42 例 TSP-C。Conv-T 的培训时间明显长于 Sim-T（中位数 30 天比 4 天；p = 0.0175）。与 Sim-T 研究员相比，Conv-T 研究员的术后表现评分明显较低（中位数 68 比 95；p = 0.0001），且反复出现错误的次数更多（中位数 3 比 0；p = 0.0006）。
虚拟现实辅助 TSP-C 培训可缩短培训时间并提高培训后的表现。
