Jin Binhai News (Reporter Ai Xin, Correspondent Wang Peng Photo Report) Heart valve disease is one of the three major cardiovascular diseases, and aortic valve stenosis is a more common valve disease in the elderly. Recently, Liu Zhigang, deputy director of TEDA International Cardiovascular Disease Hospital, successfully performed TAVR surgery (transcatheter aortic valve replacement surgery, Transcatheter Aortic Valve Replacement, TAVR). Minimally invasive surgery brings health benefits to patients with heart valve disease and .
case1
Tianjin patient Mr. Yang is 72 years old this year and has a history of heart valve disease for nearly 40 years. In the past month, he felt that his condition was getting worse and worse. He had a little activity and had chest tightness, , palpitations, and shortness of breath, and basically lost his ability to move. He has been to many large hospitals in Tianjin and was diagnosed with end-stage heart valve disease, extremely severe aortic valve stenosis with insufficiency, extensive regurgitation in mitral valve , left heart failure, and chronic renal insufficiency. Because the condition is too critical, the doctors who receive the treatment recommend conservative treatment of drugs, but drugs alone can no longer control the development of the disease, and the torture of the disease makes Mr. Yang in pain.
Uncle Yang came to Taixin Hospital for treatment with a friend's recommendation. After improving the relevant examination, the doctor confirmed that the aortic valve had a malformation and severe stenosis, the pressure difference exceeded 110 mmHg, the left heart was enlarged, the ejaculation fraction of the heart was less than 1/3 of the normal level, and there was a risk of sudden death at any time.
The patient is old, has poor heart function, high risk of circulatory collapse, coronary artery has high risk of renal insufficiency... Considering the high risk of surgical surgery, high trauma, and slow recovery, the medical team decided to perform TAVR surgery - use minimally invasive Change the valve to improve symptoms. After improving the preoperative preparations for heart, lung, and kidney function treatment, the multidisciplinary medical team fully discussed and analyzed the patient's condition, repeatedly discussed each step and details of the operation, and did a good job in the situation that may occur during and after the operation. Plan to ensure that the surgery is foolproof.
Postoperative imaging
During surgery, with the tacit cooperation of multiple departments such as anesthesia, extracorporeal circulation , radiation, ultrasound, etc., and with the support of artificial heart and lung external circulation, the medical team achieved accurate release by adjusting the delivery system to the best position to achieve accurate release Prosthetic valve. After balloon dilation, the patient's transvalve pressure difference immediately dropped significantly to normal level. In order to evaluate the surgical effect, the medical team performed aortic angiography, coronary angiography and cardiac ultrasound on the patients. The results of various examinations showed that the valve implantation position was good, the morphology was complete, and the blood flow was smooth. The prosthetic valve worked normally and the operation was successful.
Uncle Yang's symptoms of chest tightness and shortness of breath have disappeared, and he can get out of bed and move on the same day after the operation. After recovery, he was discharged from the hospital successfully.
case2
Another Mr. Zhao who underwent TAVR surgery was 70 years old and was admitted to the hospital for acute myocardial infarction. After examination, Mr. Zhao's coronary artery blood vessels were severely stenosis and severe aortic valve stenosis, and his heart function was extremely poor. An emergency stent was implanted to solve the blood vessels related to myocardial infarction and temporarily relieve the danger of life. During the hospitalization period, Mr. Zhao suffered from critical situations such as loss of consciousness, refrain from calling, and cardiac arrest and . After a team consultation plan, Mr. Zhao solved other coronary vascular problems and also solved the problem of severe aortic valve stenosis.
Liu Zhigang led his team to successfully perform coronary stent implantation +TAVR one-stop surgery for him. A successful operation for the patient solved the two problems of right coronary stenosis and aortic valve stenosis. After the operation, Mr. Zhao recovered well and was discharged from the hospital smoothly.
TAVR Medical Team
TAVR surgery provides a new option for treating aortic valve stenosis for patients with critical aortic valve disease, especially those who cannot undergo surgical valve replacement surgery or have a high risk of surgery. The mature operation of this operation shows that Taixin Medical Team has the ability to provide safe and complete multidisciplinary team diagnosis and treatment plans for patients with critical aortic valve disease with complex conditions, demonstrating the comprehensive ability of the medical team to deal with critical cardiovascular diseases.

Popular Science Knowledge
Aortic valve is the first door for blood to leave the heart. The heart (left ventricle) constricts and injects blood into the aorta through the aortic valve, maintaining the body's normal blood pressure and supplying blood to the whole body. When the aortic valve becomes stenosis, the blood flow of the heart is blocked and the heart is insufficient to supply blood to various organs of the body, which will cause ischemia symptoms in the heart, brain and organs throughout the body. Studies have shown that if patients with severe aortic stenosis who have symptoms have not been treated, more than half of them will die within 2 years, and the 5-year survival rate is only 20%.
Traditional thoracic valve replacement surgery will open the patient's chest cavity, stop the heart, and have a higher risk of surgery; now, TAVR, a minimally invasive surgical method, has become a first-line treatment for aortic valve stenosis in the elderly. TAVR surgery does not require chest opening. A 2-4cm incision is made from the patient's leg. The blood vessel extends and uses a catheter to send the prosthetic valve to the narrow area and replaces the original lesion valve, which has the advantages of little trauma, fast recovery, and low risk.
