[Minimally invasive cardiac surgery with the aid of three-dimensional computed tomography(3DCT) image projection on the body surface].

: Port-access minimally invasive cardiac surgery (MICS) is complicated by limited skin incision and surgical field. In order to optimize the set-up and port placement in this surgery, we have employed image overlay technique prior to operation consisted of three-dimentional computed tomography (3DCT)image projection on the patient surface. With the aid of this technique, we successfully performed port-access MICS in 12 patients and mitral valve replacement in 1 patient with severe mediastinal displacement after previous pneumonectomy. Image overlay projection could allow surgeons to view underlying anatomical structures virtually and obtain a good operative field. Our proposed technique would be expected to make port-access MICS easier and probably safer in this particular circumstance.
