  Minimally invasive cardiac surgery: Experience of Port-Access Cardiac Surgery

We have conducted cardiac surgery using the first 'port-access method' in Japan. It is a less stressful and less-invasive technological innovation in the field of open cardiac surgery without sternotomy. We have performed many cases and have achieved significant results.
We received a grant-in-aid for scientific research from the Japan Science and Technology Agency from 2000 to 2003, and developed a new original catheter for injection of cardioplegia and aortic vent and introduced it to the world.
More than 130 patients who have undergone the port-access operation, which is minimally invasive surgery, were able to be discharged within a week after their operation.
Utilizing a new computer technique, totally endoscopic open-heart procedures with robotic-assistance were developed and we performed the first successful robotic cardiac surgery in coronary artery bypass grafting and mitral valve repair in Asia.
