近年心臟血管疾病已躍升為全球十大死因的第一位，台灣的盛行率及發生率也逐年上升。傳統心臟外科所使用的開胸或開心手術，已逐漸以低侵入性的心導管血管介入性治療術為主。此手術除了可降低傷口感染、減少全身麻醉、縮短住院時間等優點外，相較傳統外科手術有更高的經濟效益。
通常醫師面對到新的技術或手術用具，常有缺乏練習機會的現象。在傳統的教學上，最為常見的是採取一對一教學。本研究“用於心房中膈缺損手術之雙導管模擬系統設計研究”，此系統不但能提供手術中真實遇到的情況做模擬，例如導管碰撞到血管以致使用者手部得到的力量回饋，我們也呈現虛擬實境的場景以應對導管位置的變化，以便使過程更加逼真和教育效果。此種利用虛擬實境的方法讓使用者可以在毫無風險且低成本的環境下，不斷重複練習手術已達到熟練效果。

In recent years, cardiovascular disease has become the top one cause of death in developed countries, and it is also getting more and more common in Taiwan. The traditional cardiac surgery has been gradually replaced by Interventional Catheterisation. The Interventional Catheterisation could reduce the possibility of surgical infection, general anesthesia and the time of being in hospital, it is much more economic and effective than the traditional surgery.
Normally, when doctors face a new technology or surgery equipment, the most common problem for them is the lack of practice, and in traditional education, they usually use one-on-one training. In our study, “Double-catheter simulator system for atrial septal defect” can not only simulate the real situation of surgery, like the hand feel feedback of catheter and blood vessel, the system can also shows the simulated situation on the screen in order to make the surgery more real and enhance the education effect. This system is inexpensive and without any risks, users can improve their surgery skill through their practices.
