[Thought on the techniques of totally thoracoscopic cardiac surgery]

Minimally invasive surgery has become the guiding principle of the entire surgical treatment. In last 16 years, totally thoracoscopic cardiac surgery (TTCS) has developed rapidly, and achieved good results. However, there are obvious differences between the basic surgical techniques of TTCS and of conventional cardiac surgery. At present, there is still lack of standard and in sufficient evidence in the surgical techniques of TTCS. It requires professional and standardized training and evidence-based research on TTCS, including indication selection and procedure standardization, to improve the therapy level of TTCS further.
