st year, increasing from 21 surgeries in 2000, the first year he returned to Zhengzhou from Australia, he said.
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.

oomed flight had followed Boeing’s recommended procedures, at least in part, by disabling the automated anti-s
tall system of the 737 Max 8 but were unable to regain control of the plane before it crashed.
At a news conference in Addis Ababa, the nation’s transportation minis
ter confirmed earlier indications that the plane’s anti-stall system was repeatedly triggere
d in the minutes between the takeoff and crash, but he did not draw definitive conclusions about the crash’s cause.
“The pilots turned the MCAS on and off, but I can’t say how many times, because we will find t
hat out when we have the final report,” Dagmawit Moges, Ethiopia’s transportation minister, told The N
ew York Times. Moges was referring to the anti-stall Maneuvering Characteristics Augmentation System.
