cardiac operation的意思|示意

Cardiac operation, also known as cardiothoracic surgery, is an essential form of surgery that is performed on the heart and chest. It is a major form of treatment used to treat conditions such as coronary artery disease, heart valve disease, and congenital heart defects.

This type of surgery is highly specialized and requires a highly experienced surgeon and surgical team. The patient must be thoroughly evaluated and undergo several tests before any surgery is performed. Generally, patients who are undergoing a cardiac operation must be healthy enough to withstand the surgery.

The goal of cardiac surgery is to improve the function of the heart and its associated blood vessels. Depending on the patient's circumstances, the surgery may involve bypassing damaged areas with artificial grafts, repairing damaged heart valves, or removing blockages caused by plaque buildup.

During the procedure, the heart is usually opened by making an incision in the chest. The surgeon can then access the heart and treat the medical condition. In some cases, the patient is placed on a heart-lung machine that pumps oxygenated blood to the heart to allow for surgery without stopping the heart.

The most common cardiac operations include coronary artery bypass grafting (CABG) to bypass blocked or narrowed arteries, valve replacements to treat or prevent heart valve defects, and open-heart surgery to repair congenital heart defects. There are other less common operations, such as ablation procedures for irregular heart rhythms and heart transplantation.

Cardiac operations can be life-saving procedures, but they also come with risks, such as infections, bleeding, and heart rhythm irregularities. Patients should discuss the risks and benefits of a cardiac operation with their doctor to ensure they are making an informed decision.
