Cheng hoped the schematic diagrams could make a contribution for the prevention and treatment of cardiovascular diseases in the future.
Besides his persistence on drawing the schematic diagrams, he also keeps improving techniques for his surgeries.
He has been using the 8-0 sutures, the most delicate and fine surg
ical stitches for heart surgeries, ever since he came back to the hospital in 2000.
“For the anastomosis (or connection) of tiny coronary blood vessel in heart surgery, th
e 8-0 sutures can maintain better blood flow to the heart compared with other size of threads,” Cheng said.
This is a challenge for a surgeon because he has to be very gentle in the process when co
nnecting the blood vessels of 1.5-2.0mm with this kind of fine sutures, either not too loose or not too tight.
Cheng is one of the five surgeons who use this technique in almost every case of coronary bypass operation in China, according to Dahe Daily.
