1. Indications

The injection procedure for selective coronary angiography is indicated for various cardiovascular assessments. The following conditions may warrant this procedure:

• Coronary Artery Disease - This condition involves the narrowing or blockage of coronary arteries, which can lead to chest pain (angina) or heart attacks.
• Assessment of Cardiac Symptoms - Patients presenting with unexplained chest pain, shortness of breath, or other cardiac-related symptoms may require this procedure to evaluate coronary artery status.
• Preoperative Evaluation - Prior to certain cardiac surgeries, this procedure may be performed to assess the coronary anatomy and determine the need for interventions such as angioplasty or bypass surgery.
• Follow-up of Previous Interventions - Patients who have undergone previous cardiac interventions may need this procedure to evaluate the patency of stents or bypass grafts.

2. Procedure

The injection procedure for selective coronary angiography involves several critical steps to ensure accurate imaging of the coronary arteries. The following procedural steps are typically followed:

• Step 1: Catheter Insertion - A catheter is introduced into the patient's vascular system, usually through the femoral or radial artery. The catheter is carefully advanced through the arterial system towards the heart.
• Step 2: Catheter Positioning - Once the catheter reaches the coronary arteries, it is positioned selectively in the artery of interest. This precise positioning is crucial for obtaining accurate images of the coronary anatomy.
• Step 3: Injection of Contrast Material - After the catheter is correctly positioned, a radiopaque contrast agent is injected through the catheter. This contrast material enhances the visibility of the coronary arteries during imaging.
• Step 4: Imaging Acquisition - As the contrast material flows through the coronary arteries, a series of images are captured using fluoroscopy or other imaging modalities. These images provide detailed views of the coronary arteries, allowing for the assessment of any abnormalities.
• Step 5: Catheter Removal - Following the imaging, the catheter is carefully withdrawn from the vascular system, and appropriate post-procedure care is initiated.

3. Post-Procedure

After the injection procedure for selective coronary angiography, patients are typically monitored for any immediate complications, such as bleeding or allergic reactions to the contrast material. It is essential to assess the access site for any signs of hematoma or infection. Patients may be advised to rest and limit physical activity for a specified period following the procedure. Additionally, hydration is encouraged to help flush the contrast material from the body. Follow-up appointments may be scheduled to discuss the results of the angiography and any further treatment options if necessary.
