After graduating from Medical School at the University of Hong Kong, I soon headed for post-graduate training at the Glasgow Royal Infirmary in Scotland, United Kingdom.

​

Proceeding overseas quickly helped me to become the first in my graduating class to attain Membership of the Royal College of Physicians of the United Kingdom. During further training at the Hammersmith Hospital Royal Postgraduate Medical School in London, England, I gained essential knowledge in Echocardiography, a notable skill that led me later to establish the 1st Echocardiogram service in Hong Kong.

​

Previously, internal heart structures could only be visualised by X-rays. Still, echocardiography projects sound waves at the heart, then catches the rebound of these waves returning from the heart, to display the heart's interior without X-rays and without inserting any instrumentation into the body.

​

My 2nd notable experience came when X-ray technology became computerised so that body structures could be demonstrated as images in the form of cross-sections of the body, thus allowing the small arteries of the heart to be analysed in detail.  Implementing this technology at the X-ray department of Matilda Hospital, I established the first unit in Hong Kong to conduct computerized cardiac examinations, also known as Cardiac CT.

​

My 3rd notable experience came in 1990, when the Division of Cardiology of the Chinese University of Hong Kong wanted to explore the use of a type of sound energy (called Shock Waves) to benefit patients experiencing failure of Balloon expansion procedures for coronary artery obstructions. I had the opportunity to participate in this trial by applying shock waves, which stimulated the growth of new blood vessels at critically occluded coronary locations, achieving success with no fatalities in all study subjects. I have since worked with the Chinese University whenever a hybrid approach is needed, to supplant therapy for those cases unable to achieve full unblocking of their coronary disease from conventional Balloon or Open-heart surgery. 

​

Having had the benefit of these three developments, I have applied these technologies in my practice apart from carrying out other usual types of Cardiological care.

​

​Thus, a useful routine I have developed is to employ Echocardiography to evaluate the status of the heart's internal structures and function, while the integrity of the heart's coronary arterial circulation can be deduced from Cardiac CT, and if narrowed coronary vessels did not improve adequately after balloon angioplasty or open-heart surgery, there is still the option of Cardiac Shockwave Therapy.
