Over the past decade, the operative treatment of heart disease has made great progress. Developments like the port access surgery and robot telemanipulation system have not only revolutionized the field of cardiac surgery, but have also played a critical role in the devel­opment of modern day medicine. This innovation is an operation known as Endoscopic Heart Surgery, which achieves all the desired results, but with minimal harm to the patient. Endoscopic heart surgery is a reliable alternative to conventional surgery for the treatment of different cardiac diseases.
