YANGON, March 6 (Xinhua) -- Myanmar's Yangon region chief minister U Phyo Min Thein had undergone heart surgery successfully and he is now in good condition, according to an announcement of the Ministry of Health released Monday.
The six-hour surgery, performed on U Phyo Min Thein at Yangon's Yankin Children's Hospital on Sunday by a team of veteran Myanmar doctors, marked an extraordinary milestone for medicine in Myanmar.
