Experience in treating a case of the cardiac rupture during transcatheter aortic valve implantation procedure

摘要

To the Editor: A 70-year-old male patient underwent transcatheter aortic valve implantation (TAVI) for severe aortic stenosis. Echocardiography showed that the peak velocity in aortic valve was 4.33 m/s, with a peak pressure gradient of 75 mmHg and a mean pressure gradient of 38 mmHg. The end-systolic dimension and end-diastolic dimension of left ventricle was 31.7 and 50.0 mm, respectively. The internal diameter of aortic annular was 30.7 mm, and the diameter of aortic sinus was 37.3 mm. The area of valve was 0.87 cm2. The computerized tomography indicated a bicuspid aortic valve of 27.3 mm diameter according to 85.6 mm perimeter of aortic annulus, or an aortic valve of 27.4 mm diameter according to 569 mm2 valve orifice area. A 26 mm Venus-A valve (Venus Medtech, Hangzhou, China) was implanted.
