The 60 -year -old elderly's heart expansion and severe heart failure. When the treatment of drugs is invalid, experts of the Hepatoya Clinical Medicine Center of Tongji Medical Institute of Huazhong University of Science and Technology implant a downturn for it and open a "flood discharge for the blood blocked on the left heart. "Tao" relieves the symptoms of heart failure of the elderly. On July 26, the old man had a significant narrowing heart when he reviewed again, and he could climb the 6th floor in one breath.

The 67 -year -old Zhang Dad (Hua surname) said that in the past 8 years, he has repeated his breath, and he has difficulty breathing. He has also ran many hospitals over the years, insisting on medication, and still improved. Three months ago, he rushed to the Tongji Medical College of Huazhong University of Science and Technology to take a doctor for the Liyuan Park Clinical Medicine Center.

After inspection, the left ventricular of the elderly expanded significantly, the heart contraction function decreased, and the ejection score was only 35%(normal is greater than 55%). The final diagnosis was "dilated myocardial disease", and the drug treatment effect was limited. In order to help the elderly improve their symptoms, doctors give suggestions that minimally invasive surgery implanted into the atrium diversion.

In other words, doctors perforated in the middle of the two atriums and implanted the nickel -titanium alloy material to divert the small amount of blood in the left atrium to the right atrium, thereby alleviating the capacity load of the left atrium, reducing the congestion of the pulmonary vein, and improving breathing Difficulties. However, because the aperture is difficult to control, the surgery has high requirements for doctors. If the pore diameter is too large and the blood diversion increases, the symptoms of gravity failure will be added; if the pore diameter is too small, spontaneous closure may occur, and the diversion effect may not be available.

Director Xiao Shunah, the Cardiovascular Clinical Medicine Center of Tongji Medical College of Huazhong University of Science and Technology, said that because it is a minimally invasive surgery, the elderly only need to be anesthesia, and the whole process is sober. On the same day, the team of experts implanted the downtale in the heart with only half an hour of surgery, and the elderly quickly felt that breathing was smooth. 3 days after the operation, the old man was discharged smoothly. On July 26, he came to the hospital to review again. The heart ultrasound reminded that the left ventricle became smaller and the heart function improved. The old man said that he was able to climb the 6th floor in one breath.

It is reported that my country's heart failure people are huge and stubborn heart failure for the effects of drug treatment. If there is no economic conditions to accept mechanical auxiliary devices or heart transplantation, if it meets the indications Difficulty breathing.

Xiao Shunah said that the diversion of the heart room is a new method of treating heart failure in the world. It establishes a traffic bridge in the left and right heart room through the intervention method to mix the blood of the left and right atrium, adjust the blood power to a relatively stable state, and relieve heart load. At present, my country's independently developed room interval distribution device has conducted clinical research in multiple domestic cardiac centers, and there will be a benefit of 10 million patients with heart failure in the future.
