Chinanews.com Guangzhou, March 29 (Cai Minjie, Zhang Lanxi, Jin Ting) Guangdong Provincial People’s Hospital announced on the 29th that the hospital’s cardiac surgery team implanted a “thumb” size for a 54-year-old woman diagnosed with end-stage heart failure. Only 90 grams of “artificial heart”, according to reports, this is the lightest magnetic levitation centrifugal artificial heart.
Ms. Wu (pseudonym) developed chest tightness and asthma, accompanied by palpitations and other symptoms a year ago. Since August last year, she had worsened shortness of breath, coughed up sputum with white foam, and intermittent edema of both lower extremities. The examination results of Guangdong Provincial People’s Hospital showed that she had an enlarged heart with severe tricuspid regurgitation ventricular apical thrombus and moderate pulmonary hypertension.
Heart transplantation and artificial heart are important means for the treatment of such patients with severe heart failure (ie, heart failure). “But the preoperative examination found that there are antibodies in her body, which will lead to rejection after heart transplantation, which is a contraindication for heart transplantation.” Huang Jinsong, deputy director of the Department of Cardiac Surgery of Guangdong Provincial People’s Hospital, said that after consultation with multidisciplinary experts in the hospital, After obtaining the consent of her family, the hospital decided to implant an “artificial heart” for her.
The “artificial heart” is actually a “pump” implanted in the original human heart, which directly pumps the blood in the heart into the aorta to supply the needs of the human body and make the “scratch” The ventricle is rested. The artificial heart products currently used in my country mainly refer to left ventricular assist devices. Studies have shown that the 3-year survival rate of left ventricular assist devices is 80%, which is close to the effect of heart transplantation, and has been widely used in developed countries in Europe and America.
After precise adjustment, the 90-gram magnetically levitated heart ran smoothly in the patient’s body with stable hemodynamic data. Only one week after the operation, Ms. Wu was able to move freely and was discharged from the hospital.
“The traditional artificial heart has a mechanical bearing device, which will lead to a higher proportion of thrombosis.” Huang Jinsong said that the new generation of artificial heart uses magnetic levitation technology, no mechanical bearing, and less damage to the blood, which can Allow patients to carry long-term survival.
Huang Jinsong said that at present, the magnetic levitation artificial heart is in the clinical evaluation stage, scientists are studying wireless charging technology, and the device will also tend to be miniaturized and fully implantable. (End)
