1. Indications

The injection procedure for selective left ventricular or left atrial angiography (CPT® Code 93543) is indicated for various clinical scenarios where detailed visualization of the left heart structures is necessary. The following conditions may warrant this procedure:

• Assessment of Cardiac Function This procedure is often performed to evaluate the function of the left ventricle and atrium, particularly in patients with suspected heart failure or other cardiac dysfunctions.
• Investigation of Coronary Artery Disease It may be indicated in patients with symptoms suggestive of coronary artery disease, where understanding the left heart's anatomy and function is critical for diagnosis and treatment planning.
• Preoperative Evaluation Prior to certain cardiac surgeries, this angiography can provide essential information regarding the left heart's condition, aiding in surgical planning.
• Assessment of Valvular Heart Disease The procedure is useful in evaluating the left atrium and ventricle in patients with valvular heart disease, helping to determine the severity and implications of the condition.

2. Procedure

The procedure for selective left ventricular or left atrial angiography involves several critical steps to ensure accurate visualization and assessment of the left heart structures. The following procedural steps are typically followed:

• Step 1: Catheter Insertion A catheter is introduced into the patient's vascular system, often through the femoral artery or another access point. The catheter is carefully advanced through the blood vessels towards the heart, specifically targeting the left side.
• Step 2: Catheter Positioning Once the catheter reaches the left heart, it is positioned in either the left ventricle or left atrium. This precise positioning is crucial for the subsequent injection of contrast media and visualization of the heart structures.
• Step 3: Injection of Contrast Media After proper positioning, a contrast agent is injected through the catheter. This contrast media enhances the visibility of the left heart chambers during imaging.
• Step 4: Imaging Acquisition Following the injection, imaging techniques such as fluoroscopy or X-ray are employed to capture angiograms of the left ventricle and/or left atrium. These images provide detailed information about the anatomy and function of these heart structures.

3. Post-Procedure

After the completion of the selective left ventricular or left atrial angiography, several post-procedure care steps are typically recommended. Patients are usually monitored for any immediate complications related to the catheterization, such as bleeding or arrhythmias. 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 to facilitate recovery. Additionally, healthcare providers may schedule follow-up appointments to discuss the results of the angiograms and any further diagnostic or therapeutic interventions that may be necessary based on the findings.
