  ◆ On February 10, 2018, the heart team led by Song Bing, Cardiology Department of the First Hospital of Lanzhou University successfully implemented the first transcatheter aortic valve replacement (TAVI) in a patient with high-risk aortic valvular disease.
  ◆ The patient is 66 years old
  Chief complaint: Intermittent chest tightness, shortness of breath for 25 years, symptoms worsening for 8 months, hypertension, diabetes
  ■ Ultrasound echocardiography: Severe aortic valve stenosis with severe calcification, 30% EF value, 50mmHg across valve
  ■CTA prompt: Type 0 two-leaf valve, with severe calcification

  After the Heart Team discussion, it was decided to use the 25mm J-Valve interventional valve for TA-TAVI surgery

  ◆ Surgery was performed at the heart catheterization room of the First Hospital of Lanzhou University.
  ■ After anesthesia, place an esophageal ultrasound probe. The left femoral vein was punctured and a temporary pacing electrode was placed.
  ■ Dissect the right femoral artery and vein, and insert the contrast catheter to the aortic root through the right femoral artery.
  ■ Make a 4cm incision in the fifth intercostal space on the left chest, open the pericardium, and puncture the heart with a purse-string suture.
  ■ Adjust the C-arm to show the aortic sinus floor at the same time and in the same plane.
  ■ After the apical puncture, place the J-tip flexible guide wire into the ascending aorta, place the JR4 catheter through the guide wire, place the guide wire distal to the descending aorta, replace the 2.6m stiff guide wire, and remove the JR4 catheter.
  ■ Catheter angiography to determine the position of the aortic valve.

  ■ Esophageal ultrasound revealed that the implanted bioprosthetic valve was working properly. The transvalvular pressure difference was 10 mmHg, and the valve was leaked slightly.
  ■ The angiogram showed normal left and right coronary arteries and normal valve morphology.
  ■ Remove the esophageal ultrasound probe, remove the apical and femoral artery guide wire, place the drainage tube, and suture the incision layer by layer. At the end of the surgery, the patient returned to the ICU ward.
