Generally, in cardiovascular surgery, the skin must be incised 20-25 cm along the middle of the chest, and the sternum opened. However, made possible by recent innovations, a procedure that avoids cutting the sternum, known as minimally invasive cardiac surgery (MICS) has started to become widespread in Japan. We employ MICS whenever possible, to minimize the physiological strain of surgery.
Minimally invasive valvular disease surgery (MICS)
It is cosmetically superior, because the bone is not cut, and the scar is hidden under the right breast.
Discharge within one week after surgery is possible.
Because of the small incision, blood loss is reducedm, and transfusion is often not necessary.
The low invasiveness and other pain-blocking techniques lead to lower pain levels.

However, there are cases where MICS is unsuitable because of body shape, blood vessel or lung conditions, etc. so we carefully investigate whether MICS is possible before surgery, to ensure the safety of patients.
Robotic surgery using surgical-assistance robot Da Vinci leads to even fewer injuries than MICS as it allows even less invasive cardiac surgery by performing all operations via a few small holes. Medically approved in 2015, robotic cardiac surgery
is now possible possible, although not yet covered by insurance. At present, in order to receive robotic cardiac surgery, patients must cover the expense themselves.
We started off with hybrid coronary artery bypass surgery using MICS and the robot. The robot collects a blood vessel (internal thoracic artery) from inside the chest and then coronary artery bypass surgery is performed with MICS. As medical expenses are presently covered by research funding, there is no financial burden on the patients. We also plan to start robotic surgery for mitral valve surgery in the future.
