Coronary heart disease is a common high-risk heart disease. In 2020, the death toll from "coronary heart disease" in Hong Kong will account for nearly 60% of the total deaths from heart disease.
However, "Tongbo" surgery cannot be done once and for all. Chen Yuhao, a cardiologist at the Chinese University of Hong Kong Hospital, pointed out that calcification in the blood vessels will always accumulate and coagulate in the blood vessels, which may make the stent after the "Tongbo" operation impossible. Open completely, obstructing blood flow.
The latest and improved "360-degree cardiac atherosclerotic resectoscope", the diamond coating on the grinding head, can grind calcifications into fine debris. It is a surgical instrument capable of passing through blood vessels and fragmenting calcifications. , The success rate of surgery reached 90%.
Dr. Chen explained that the coronary arteries that supply the heart's blood flow will gradually form atherosclerotic plaques due to blood lipids and calcium deposits in the arteries, causing the blood vessels to become narrow or blocked.

Chen Yuhao, a specialist in cardiology at the Chinese University of Hong Kong Hospital, points out that hypertension, hyperlipidemia, smoking and obesity are also high-risk factors for "coronary heart disease."
In Hong Kong, it is "a deadly killer that cannot be ignored."
He pointed out that in 2020, the death toll from "coronary heart disease" in Hong Kong accounted for nearly 60% of the total deaths from heart disease.
Vascular calcification may prevent the stent from being fully opened after the "Tongbo"
Dr. Chen explained that the coronary arteries that supply blood flow to the heart will gradually form atherosclerotic plaques due to accumulation of blood lipids and calcium deposits in the arteries, resulting in narrowing or blockage of blood vessels; "Por Tsai" surgery to open up narrow or blocked coronary arteries.
In addition, in order to reduce the risk of narrowing the blood vessels in the future, doctors may implant metal stents into the blood vessels.
However, Dr. Chen added that "Tongbo" cannot be done once and for all. The calcification in the blood vessels will always accumulate and coagulate in the blood vessels. There is a chance that the stent after the "Tongbo" operation cannot be opened completely, hindering blood flow. .
90% of patients with coronary heart disease will have calcifications in their cardiovascular system
He pointed out that as many as ninety adults with "coronary heart disease" who had reached the age of 70 had calcifications in their cardiovascular system.
There are generally several types of "Tongbo" surgery, including "Coronary artery atherectomy", "Orbital rotational atherectomy", "Intravascular shock wave" and so on.
However, many cases of vascular calcification are complicated or require a combination of different methods. For example, patients with severely narrowed blood vessels need to undergo rotational atherectomy to remove part of the atherosclerotic plaque. However, the blood vessels may only be slightly dilated, and other methods are needed to further remove the calcifications before placing the stent.
The success rate of new technology surgery has reached 90%
The latest and improved "360-degree cardiac atherosclerotic resection device", the doctor will insert a special "drive wire" guide wire into the blood vessel, and the metal drill bit will be sent to the front of the narrowed part in the blood vessel, up to 16 per minute 10,000 to 180,000 revolutions.
Dr. Chen pointed out that the diamond coating on the grinding head can grind the calcifications into fine debris. It is a surgical instrument capable of passing through blood vessels and fragmenting the calcifications. The success rate of the operation is even more than 90%.
He also pointed out that the old "Tongbo" surgical instrument requires the use of both hands and feet, and requires the assistance of an assistant; while the newly improved instrument can be easily operated by one person, and the operation and preparation time is relatively shortened, making the operation safer.
