The 67-year-old Grandfather Feng has been suffering from chest pain for 5 years. He will have a pain for a minute or two except for heavy work. The rest of the time is not a big problem, so the elderly have never taken it seriously. But not long ago, the symptoms of chest pain of Feng Grandpa were obviously aggravated, and daily activities caused chest pain, and they sweated. Under the escort of his family, he lived in the Department of Cardiology in the First Hospital of the city. After examination of color Doppler ultrasound and coronary angiography, his coronary artery was severely hardened and diffusely calcified. The most severe stenosis is 99%, and the lumen is almost completely blocked by hard, hard plaques. In the Department of Cardiovascular Surgery, the coronary intervention, coronary stenting, coronary artery stenosis and other coronary interventions failed to work, so decided to use advanced "coronary artery atherectomy" for its treatment. The new method is that the doctor sends a diamond-shaped olive-shaped 1.5 mm grinding head to the most severe lesion in the heart through a special catheter. The arteriosclerotic plaque that blocks the blood vessel is quickly ground into tiny particles by high-speed rotation. After several rounds of atherectomy, the patient's narrow vascular lumen became larger, and the doctor successfully implanted a stent for Feng Daye to restore the ischemic heart to normal blood supply. It is reported that after the operation, Grandfather Feng has no symptoms of discomfort and can get out of bed the next day. According to experts, coronary atherectomy is a new technique for interventional treatment of coronary arteriosclerosis, and it is the first case in Shijiazhuang.
