Coronary angiography A cardiac catheter examination is a diagnostic or therapeutic measure to detect and correct cardiovascular changes with the help of a catheter inserted into the vascular system. A cardiac catheter is a very thin, internally hollow instrument several meters long, with a guide wire in its central cavity. This guidewire serves to guide … Cardiac catheter examination
Heart catheter OP The aim of cardiac catheter surgery is to examine the coronary arteries or the heart itself more closely with the aid of a contrast medium and X-ray technology. A cardiac catheter operation is performed as follows. First, the patient is prepared for the operation in the cardiac catheter laboratory. Since the physician … Heart catheter OP | Cardiac catheter examination
Risks As with any procedure, in some cases (cardiac catheterization) complications can also arise from a cardiac catheterization. Since the cardiac catheter is advanced through the arterial vascular system into the heart, it is also in close contact with the cardiac conduction system, which is responsible for each individual heartbeat. If the nervous system is … Risks | Cardiac catheter examination
Wrist access The puncture site for the introduction of the cardiac catheter is usually made through a venous or arterial access of the groin, elbow or wrist. The access at the wrist is transcarpal, i.e. via the carpus. There are then two possible arterial accesses, namely the radial artery or the ulnar artery. The radial … Wrist access | Cardiac catheter examination
Before the actual procedure, several preliminary tests are needed to assess the number, extent, and location of the narrowings, as well as risk factors. These include ECG and exercise ECG, blood tests, and a chest x-ray to evaluate the heart and lungs. Special attention is paid to the question of an existing allergy, hyperthyroidism or … PTCA: Procedure of the Examination
The coronary arteries supply blood to the heart; narrowing or occlusion can have life-threatening consequences. One method of dilating narrowed vessels in a relatively gentle manner is PTCA or balloon dilatation. In many cases, balloon dilatation can avoid open-heart surgery. Like any other muscle, the heart muscle needs oxygen-rich blood to perform its pumping function. … PTCA for Coronary Artery Dilation
The primary success rate of PTCA is very high, exceeding 90%. Except for the puncture site, the patient has no wound to heal and is virtually immediately free of symptoms and able to perform better. This can already be seen in the stress ECG the day after the examination. The downside of the comparatively simple … PTCA: Advantages and Disadvantages
