What diagnostic cardiac catheterization?
When catheters, a term coined for the hollow plastic tube 2 to 3 mm in diameter, are inserted in the arteries or veins in the arm, leg or neck of the patient, where they are routed to the heart, the process is called the diagnostic cardiac catheterization. When these catheters are placed in different heart chambers, blood pressure in the various chambers of the heart becomes measurable. Doctors can then take blood samples and inject dye to say radiographic contrast material, which allows viewing x-ray. Since, blood vessels or the heart is difficult to be x-ray visualized without using contrast dye.
Diagnostic cardiac catheterization results are very beneficial when it comes to analyzing patients with heart disease.
Why diagnostic cardiac catheterization?
The presence of any condition that history or patient's physical testing or evaluation of a patient using non-invasive techniques such as chest x-ray, echocardiogram and ECG suggests can be confirmed or excluded by catheterization diagnostic heart. When the results of clinical and noninvasive tests of a patient are vague, diagnostic cardiac catheterization can simplify the situation. Any kind of abnormality in the patient who is going to cardiac surgery may also be determined by the same while others associated anomalies can be excluded.
How is it done?
The X-ray machine used in the procedure has a table below, on which the patient under sedation often placidly is positioned. The entry point is anesthetized, after which catheters are inserted into the patient's neck, arm or leg vein or artery. X-ray visualization is performed, thereafter, while the catheters are directed towards the heart. Heart disease is determined with the preferred and experience of the operator, and the patient's anatomical deciding the unique features of the procedure as venous or arterial approach and location.
The catheter may be inserted either percutaneously into a vein or artery, or by denudation. The first approach involves the cleaning of the skin that covers the artery or vein with sterile soap, followed by the injection of an anesthetic into the skin surrounding the artery or vein. A hollow needle is used to puncture the blood vessel, after which a flexible wire is directed to the blood vessel. The needle is then removed and a hollow plastic tube with a length of about 6 inches is inserted into the container. The wire is then removed. The liner must be correctly placed in the blood vessel to the catheter to enter via the same right in the heart chamber with radiographic visualization. After the procedure is completed, the surgeon removes the catheter and the sheath, and the bleeding is prevented by applying local pressure for about 20 minutes or less.
The other way to carry out the diagnostic cardiac catheterization is using denudation. In this method, the sterile soap is used to clean the area above the elbow crease (1-2 cm above) of the branch, which is then anesthetized. A small incision is introduced and special instruments are used to isolate the vein or artery. Another cut is introduced into the blood vessel via a catheter which is inserted into the heart using radiographic visualization. After the procedure, the surgeon removes the catheters. The incisions are introduced darned.
How diagnostic cardiac catheterization help?
Diagnostic cardiac catheterization can help in the diagnosis:
cardiac valve problems
Congenital heart disease
Coronary artery disease
Abnormal cardiac output
Decreased heart function
Heart attack
The high pressure in the cardiac chambers or vessels
the heart muscle infection
Inflammation in the cardiac muscle
Heart muscle transplant rejection
