    Teruyasu Nishino
    Medical Doctor
  • Background
    Teruyasu Nishino was born in 1976. He studied in Mayo Clinic Elective Clerkship and graduated from Juntendo University. He is a member of the Japanese orthopaedic association. He has managed variety of companies including medical company, social welfare service corporation and other corporations.
“Learn more flow, save more lives” is the corporate mission of Cardio Flow Design, and we aim for a world where medical doctors can diagnose using blood flow easily. Along with the development of IT technology, MRI, and CT, we are now able to know much more deeply about blood flow. Based on this data, we can predict possible future diseases and schedule planned surgeries in advance, which will bring significant innovation to the diagnosis and treatment of cardiovascular medicine and surgery. To make blood flow analysis become a diagnostic technology for the new generation, our team of doctors and engineers are steadily developing their blood flow analysis technology, and we believe the day it can be used for actual diagnosis is close. However, as this field can use much more research, if there is any idea regarding blood flow that can contribute to medical, please do not hesitate to contact us.

  • Background
    Keiichi Itatani was born in 1977. He is a cardiovascular surgeon and a researcher of fluid dynamics. Since he graduated from the university of Tokyo in 2002, he has been involved in the clinical practice of cardiovascular surgery, and at the same time, has been thinking about “what the optimal cardiovascular surgery is”, and he started research of fluid dynamics in cardiology. He developed blood flow simulation method useing computational fluid dynamics (CFD), blood flow imaging with phase contrast MRI and echocardiography vector flow mapping (VFM) and he invented energy loss calculation method. He became an endowed chair, Department of Hemodynamic Analysis in Kitasato University School of Medicine in 2012. He founded Cardio Flow Design Inc in 2015, and he is working for the department of cardiovascular surgery in Kyoto Prefectural University of Medicine from 2015. He became an endowed chair of Cardiovascular Imaging Research Laboratory in Kyoto Prefectural University of Medicine in 2016. He became an adult congenital heart surgeon in Kyoto Prefectural University of Medicine in 2018. He became Hospital lecturer in the department of cardiovascular surgery in Osaka City University in 2021.He became a lecturer in cardiovascular surgery at Nagoya City University in 2022.He became an associate Professor at Nagoya City University Graduate School of Medical Sciences, Department of Cardiovascular Surgery, Director of the Adult Congenital Heart Disease Center in 2023.
Cardio Flow Design, Inc. was founded with the aim of developing the blood flow imaging, which had been an advanced research product, to an essential and practical tool and the de facto standard for cardiology and cardiovascular surgery. Blood flow imaging is a translational research field from medical science and computer technology, and we are aiming toward developing engineers and medical scientists for bridging the gap between advanced high-end research outcomes and medical practice. Our goal is to produce new medical research service tools based on flexibility outside of existing frameworks and on profound knowledge and skill on basic science, which would improve the reproducibility of diagnosis and treatment of cardiovascular diseases.
