Au Wing Kuk Timmy (Chinese: 區永谷) is a specialist in cardiothoracic surgery in Hong Kong. Currently, he is a consultant cardiothoracic surgeon at Queen Mary Hospital and an honorary clinical associate professor at the University of Hong Kong Hong.[1][2]Au was educated at St Stephen’s College[3] and subsequently graduated from the University of New South Wales, Sydney, Australia in 1988.

Career

He started his career in cardiothoracic surgery in 1994 as a surgical registrar at St. Vincent’s Hospital, in Sydney, Australia. He moved to Hong Kong in 1995 as a medical officer in the department of Cardiothoracic Surgery at Grantham Hospital. He was appointed chief of cardiothoracic surgery in 2012 and continued to serve until 2021. During this time, he led the heart and lung transplant, and ventricular assist device program in Hong Kong. A number of major advancements in cardiothoracic surgery at Queen Mary Hospital took place during Au's tenure, including:

  • The number of ventricular assist devices for heart failure steadily increased[4][5]
  • The Queen Mary Hospital became the first hospital in Asia to successfully implant a ventricular assist device in a 13-year-old with a single ventricle[6]
  • The most complicated heart transplant procedure ever completed in the medical history of Hong Kong, when the youngest ever patient in Hong Kong underwent heart transplantation took place. This patient achieved the longest duration for PediMag BiVAD support in the Asia-Pacific region, as the patient had been sustained by the heart pump device for 58 days before the transplant[7]
  • The Organ Care System, which allows heart transplants using hearts donated by "marginal" donors and also travel further and longer distances, and can lead to expansion in the donor pool, was used for the first time in Asia, in Queen Mary Hospital[8] [9][10]
  • Short-term bi-ventricular assist device was used as a long-term device (235 days) in a pediatric heart failure patient who successfully underwent heart transplantation and continues to live a normal life to date. This was the longest duration of pediatric CentriMag BiVAD ever reported[11]
  • The latest surgical advancements in cardiac surgery were used. Queen Mary Hospital, Hong Kong became the first hospital in Asia to use the NeoChord procedure for mitral regurgitation[12][13][14]
  • First ever Submuscular abdominal implantation of the S-ICD system in a child[15]
  • Public appeals for heart/lung donation became a common practice

Au's other accomplishments as a cardiothoracic surgeon include:

  • In 2014 he used the robotic assisted technology in cardiac surgery, the first of its kind in Hong Kong[16]
  • Au was the first cardiothoracic surgeon in Hong Kong to demonstrate that EuroSCORE performed well with good calibration and discrimination in predicting mortality in local Hong Kong Chinese s undergoing CABG and heart valve surgery[17]
  • Au pioneered the routine use of endoscopic vein and radial artery harvesting for CABG in Hong Kong[18][19][20]

Research

Au researches and publishes on common cardiac surgical diseases in Hong Kong, and has authored over 60 articles to date.

Fellowships

  • Fellow of Royal College of Surgeons of Edinburgh
  • Fellow of The College of Surgeons of Hong Kong
  • Fellow of Hong Kong Academy of Medicine (Cardiothoracic Surgery)

Personal life

He is second among the three children of the Hong Kong philanthropist, Au Kim Hung (Chinese: 區劍雄)[18]wikipedia: 區劍雄 whose Au Kim Hung Love & Care Association Limited provides education to underprivileged children in China.[19][20]
