The case was the first of its kind in China, the hospital said.
The baby, Jin Chenchen, of neighboring Anhui province, was diagnosed with severe heart disease a month before he was born.
Doctors found three holes in the boys heart-one was 2 centimeters in diameter. He repeatedly came down with colds and had pneumonia three times. Doctors feared he would not live long if left untreated.
During an operation on July 3, doctors closed three holes in his heart. But Jin had difficulty breathing when he was taken off a respirator in the operating room, indicating his heart was not functioning well.
An ultrasound test revealed additional holes in the wall dividing the hearts left and right ventricles. The defects were so deep they did not show in previous exams.
To avoid cutting into his heart, doctors ended the first surgery and devised a new plan.
Normal ultrasounds only give two-dimensional images, said Zuo Weisong, director of the hospitals ultrasound department.
“Surgeons have to rely on their experience and imagination with 2-D images,” Zuo said. “That worries them when the disease is complicated.”
Sun Jian, deputy director of the hospitals cardiothoracic department, said the doctors were inspired by an online news story about some US doctors who used 3-D technology to print a heart to save a baby with congenital heart disease.
“We contacted a 3-D printing company immediately,” Sun said. “Doctors from the CT scan department worked with professional engineers and managed to print the babys heart after analyzing its images carefully and modeling repeatedly.”
To save money for the parents, they used the cheapest material. The 3-D model at a cost of 700 yuan ($109), which can be dismantled into three parts, presented detailed information to the doctors to work out a detailed plan for further surgery.
“The 3-D printing is very useful in curing children with complicated congenital heart disease,” Sun said.
“It will be used widely in many fields of medicine with the development of materials and the 3-D technology.”
On July 21, the surgeons operated again, closing the remaining holes in the boys heart. Four days later, he was taken off a respirator.
Jin was discharged on Wednesday.8.03KPhotoNight views of Harbin through the lensTibetans take train home after pilgrimage or travellingWorlds largest shaftless Ferris wheel built in ChinaAncient cities to be connected by Xian-Chengdu high-speed railwaySnow turns Harbin into winter wonderlandReed Catkin Festival held in WuhanSocietyPoliticsHot TopicsScience/TechBusinessCover StoryFTZ simplifies process to launch businessesJapan can offer experience, expat saysApplication for work streamlinedAwareness of law aids resolutionAir Force units explore new airspaceLow wages and lack of respect responsible for kindergarten abuse, experts sayLiu heralds UK partnership in education and researchAgency ensuring natural gas supplyUN envoys trip to DPRK praised by BeijingChina moves to secure natural gas supply amid rising winter demandXi asks China, Canada to work for substantial tiesCooperation necessary for success, leaders sayLiving in space: How astronauts train, eat and workTeachers excused for lunchtime drinksWaiting for Shenzhou XICancer agent found in 44 cities drinking waterAt Ikea eatery, its no pay, no stayChina lose 2-0 to Uzbekistan in World Cup qualifier, coach Gao resignsC919 gains another 55 orders, lifting total orders to 785Services offset dip in manufacturingFintech to energize real economy, cut risksChinas Long March rockets complete 60 commercial launchesEngineers achieve breakthroughChina-made components add securityOnline shopping rings up customer complaintsImport expo to focus on advanced techSME mobile market platform receives first clientsChina top importer of US soybeansAir China opens direct route from Beijing to BarcelonaInsurance-based trust launchedDandelion helping to sow the seeds of stability for membersCover storyVisa change may boost tourism to USThe wrong side of the roadBuilding ban begins to biteVillagers call on Japan to atone for massacreMost ViewedTodays Top NewsDelegation salutes Tibet anniversaryOfficials are told to act as anti-graft watchdogsGreat Wall safeguarded in united actionVice minister pledges more efforts to improve air qualityBeijing’s efforts to control air pollution start to pay offChinas military committed to reformNetizens rip singer over baby photosCentral govts growing support for TibetMonument to be built on Tianjin blast siteChina and Russia seal raft of energy dealsIn todays trending, pet dog turns out to be Artic fox, a modern recreation of Suzhous famous gardens sells for $78 million, a classroom is rented out as a hotel, and a public toilet is converted into a restaurant.HighlightsBeijing expects severe traffic congestion on next two daysWe have a heart for themBeijings preparations begin long before the parade starts8 interesting facts about the upcoming V-day ParadeHot TopicsGround level Rule of law Panda China youths Anti-terror drive Family planning Smog Fox Hunt Beijing integrates with Tianjin, Hebei China cracks down on graftSpecialGlimpses of Tibet: Plateaus, people and faith50th anniversary of Tibet autonomous region…| About China Daily | Advertise on Site | Contact Us | Job Offer | Expat Employment |Copyright 1995 -var oTime = new Date();
