Translation: “世界上，治疗心脏病最好的方式就是不要开刀。” Looking for another retrograde translation.

Here's the excerpt:


  美国有一个心脏病之父，他一生开过，开胸开一万多人。他，美国的心脏科医生都知道，尊称他为心脏病之父。他死掉以后呢，在他的墓碑上面，刻了......了一句话在上面：“世界上，治疗心脏病最好的方式就是不要开刀。”


This obviously comes from English.


What's the original English quote of: “世界上，治疗心脏病最好的方式就是不要开刀。”?
The epitaph is probably


  "I would like to think that I've left the world of cardiovascular surgery better than when I found it. That would be a suitable epitaph." — C. Walton Lillehei, 1995.

C. Walton Lillehei, the “Father of Open Heart Surgery”. This article proves Mr. Lillehei has the title "心脏病之父", and he is an American.
State of the Heart: The Practical Guide to Your Heart and Heart Surgery. This book quotes what he said as


However I cannot find that epitaph on his tombstone.



So, the statement "在他的墓碑上面，刻了..." seems not true.
