Doctors in Zhengzhou, capital of Henan province, were successful in taking out the 4-cm-long needles that were stuck in Jiang's heart, reports the China Daily.
The 44-year-old Jiang, who is fond of knitting, had no knowledge that the needles were wedged in her heart.
Doctors discovered the needles when the woman was undergoing a routine check up last month.
