Study Notes
Cardiac Catheterization Overview
- Involves inserting a long, flexible, radiopaque catheter into a peripheral vein or artery, guided by fluoroscopy or angiography.
- Used to diagnose conditions like coronary artery disease, myocardial disease, and valvular dysfunction.
Indications for Cardiac Catheterization
- Confirmation of suspected heart disease.
- Assessment of disease location and extent.
- Management of severe angina unresponsive to medications.
- Evaluation of uncontrolled heart failure, acute myocardial infarction, and ventricular aneurysm.
Contraindications
- Allergy to contrast medium.
- Pregnancy, unless its benefits outweigh risks.
- Renal failure.
- Severe infections, irreversible brain damage, or congestive heart failure (CHF).
- Inability of patient cooperation.
- Gastrointestinal hemorrhage.
Procedure Steps
- Patient positioned supine on an x-ray table with ECG leads attached.
- Continuous monitoring of blood pressure, pulse, and respiration.
- Catheterization site is shaved, cleansed, and prepped sterilely.
- Needle insertion into femoral or brachial artery/vein.
- Guide wire introduced; catheter is then placed over it into the blood vessel.
Diagnostic Procedures
- Angiography involves injecting contrast medium to image specific blood vessels.
- Other procedures include electrocardiogram, chest x-ray, echocardiography, and magnetic resonance imaging.
Patient Positioning for X-Ray
- Patient stands erect facing the image receptor, 5 cm above shoulder joints.
- Chin raised to avoid obstruction in the imaging field.
- Shoulders rotated and depressed to clear lung fields.
Technical Factors for X-Ray Imaging
- Use posteroanterior projection with suspended inspiration.
- Centering at the 7th thoracic vertebra with appropriate collimation.
- X-ray exposure set to 100-110 kVp and 4-8 mAs, with a source-image distance of 180 cm.
Outcome of Cardiac Catheterization
- Enables visualization of heart chambers, valves, and great vessels for diagnosis and treatment of coronary artery abnormalities.
- Duration of the procedure typically ranges from 1 to 3 hours.
- Following the procedure, pressure applied to the needle site to prevent bleeding; patient then monitored in recovery.
Angiographic Imaging Views
- LAO (Left Anterior Oblique) and RAO (Right Anterior Oblique) provide specific tomographic views for accurate assessment.
- PA (Posteroanterior) imaging centralizes anatomical landmarks for clearer interpretation.
- Patient instructed to inspire for cranial images to eliminate diaphragmatic shadows.
