Recently, dual flat detector imaging system in cardiovascular with magnetic navigation has been officially put into use in Zhongshan Hospital of Fudan University. Miss Xiao, the person who has severe coronary artery chronic total occlusion, became the first beneficiary.

Miss Xiao, who is 64-year old from Gansu, has a long history of hypertension and smoking. She had a symptom of severe chest pain and angina while walking. Medical examination revealed lesions occurred in all the three blood vessels, among which right coronary artery and left anterior descending artery were totally occluded. Furthermore, 90% of circumflex artery were cramped. In such case, Conventional catheterization intervention operation may cause blood vessels perforated. Because of the complicated condition, too much contrast agent will have a negative impact on the patient. On second thought, Professor Ge Junbo, the chief of Cardiology in Zhongshan Hospital and also the director of Shanghai Institute of Cardiovascular Diseases, decided to adopt the latest technology. It meant that a magnetism-navigated cardiovascular interventional procedure would be performed with the guidance of digital dual flat

First, Professor Ge opened a small hole in the femoral artery. With the help of dual flat magnetic navigation angiography, he inserted a catheter into the hole and made it through the occluded blood vessels, finally to the exact surgical site. As a result of the catheter, the right coronary artery was got through instantly, where a stent was implanted into by the effect of balloon dilatation. Then anterior descending coronary artery was also got through, and two stents were located in the area from the former descending artery proximal to the left main. Finally, a fourth stent was put into circumflex coronary artery. Overall, it takes one and a half hours to finish the surgery successfully.

At present, the patient is in stable condition.
