The magic of cardiac catheter examination: Do you know what it can do?
Cardiac catheter examination is a medical procedure for inserting a catheter into a chamber or blood vessel of the heart. This technique can be used for both diagnostic purposes and interventional treatment. Especially coronary artery catheter examination focuses on diagnosing heart problems such as coronary artery disease and myocardial infarction. This procedure is usually performed in special cardiac catheter laboratories equipped with radiographic technology and highly flexible workbenches.
Cardous catheter examination is used quite extensively, including evaluating the function and structure of the heart.
During a cardiac catheter, doctors can visualize the coronary artery through coronary angiography, a diagnostic tool that uses radiographic technology to check the condition of blood vessels. If a stenosis or obstruction of the arteries is found, the doctor can use percutaneous coronary intervention technology to open these arteries and restore blood flow.
In addition to assessing blood flow, cardiac catheterization can also be used to measure pressure in the heart, using these data to guide clinical decision-making, especially in cases such as heart failure or cardiogenic shock. For cardiac surgeons, cardiac catheterization is an important tool to understand the patient's condition.
Cardous catheter examination is not only a diagnostic tool, but its therapeutic ability cannot be underestimated.
Through catheter technology, doctors can directly intervene in areas with abnormal pressure, and even install pacemakers or defibrillators on patients with heart disease. These are all done through catheter techniques. Cardiac catheterization also exhibits important applications in certain TAVR (transcatheter aortic valve replacement) surgeries, which are particularly important for patients at higher risk.
For left heart catheter examination, doctors usually perform cannulation from the femoral or radial artery, a technique that can evaluate the degree of obstruction of the coronary artery, and interventional treatment is usually required if the obstruction exceeds 70%. Right heart catheter test is mainly used to measure pressure in the heart, especially for patients who want to evaluate pulmonary hypertension or heart failure.
Although cardiac catheterization has its risks, the treatment effect is often far greater than these risks for many patients with heart disease.
Of course, cardiac catheter examination is not without risks. Unexpected situations such as stroke, heart attack or death may occur during the operation, which makes doctors need to take caution when deciding whether to perform this procedure. Therefore, the use of cardiac catheter technology is mainly aimed at patients with heart disease with obvious symptoms and is not suitable for general screening.
With the advancement of technology, cardiac catheter examination is not limited to traditional interventional surgery, but also incorporates a variety of new technologies, including intracatheter ultrasound, electrophysiology, etc., making this technology more comprehensive. Such progress allows physicians to provide effective treatment options for high-risk patients without surgery.
In addition, even for patients with congenital heart disease, today's medical technology can repair certain structural problems through catheters, such as airbag removal surgery, and the use of alcohol ablation to improve certain heart conditions. All of this shows the potential and diversity of cardiac catheterization.
With the advancement of cardiac medicine, cardiac catheterization will undoubtedly continue to expand its application scope and bring hope to more patients. How will the future of this technology evolve? How many lives will change?
