AboutAbout the lab
Bringing cutting-edge medicine, ahead of its time, to patients
The Cardiovascular Surgery Lab is one of the clinical departments that make up the surgery labs of Osaka University, and works on the surgical treatment of heart and blood vessel diseases.
Since performing Japan's first successful open-heart surgery using a heart-lung machine in 1956, the lab has focused on improving surgical outcomes for valvular heart disease, coronary artery disease, aortic disease, and congenital heart disease, and on developing and spreading new treatments.
The 'Frontline of Treatment' section of the lab's website introduces large-vessel and minimally invasive catheter treatments that are gentle on the body, artificial hearts and heart transplantation, peripheral vascular treatment, and biodesign.
Prof. Miyagawa specializes in valvular heart disease, coronary artery bypass surgery, regenerative therapy and surgical treatment for severe heart failure, and ventricular assist devices.
Key terms

- Congenital heart disease
- Heart disease present from birth. Conditions vary widely, from mild to severe.
- Heart failure
- A condition in which the heart cannot send enough blood throughout the body, or blood cannot return adequately to the heart, so fluid accumulates in the lungs and throughout the body.
