Official Description

3D echocardiographic imaging and postprocessing during transesophageal echocardiography, or during transthoracic echocardiography for congenital cardiac anomalies, for the assessment of cardiac structure(s) (eg, cardiac chambers and valves, left atrial appendage, interatrial septum, interventricular septum) and function, when performed (List separately in addition to code for echocardiographic imaging)

Common Language Description

3D echocardiography (3DE) is a sophisticated imaging technique that provides detailed visualization of the heart's structures and functions. This procedure is particularly valuable in the management of congenital cardiac anomalies, as it allows for a comprehensive assessment of various cardiac components, including the cardiac chambers, valves, left atrial appendage, interatrial septum, and interventricular septum. The technology employs specialized transducers that can be either small, high-frequency types suitable for pediatric patients or larger versions for adults. These transducers are designed to capture real-time three-dimensional images of the heart while it is in motion, enhancing the clinician's ability to evaluate cardiac morphology and function. The 3DE system utilizes advanced computer post-processing techniques to analyze the acquired datasets, providing critical information that aids in pre-surgical planning and guides interventional catheter placements. The transducers used in 3DE feature a matrix array of thousands of piezoelectric crystals, which are arranged in a grid pattern. This configuration allows for independent activation, focusing, and steering of the ultrasound beam across multiple planes, thereby covering the entire three-dimensional volume necessary for a thorough evaluation. The ultrasound waves emitted by the transducers penetrate the heart, and the reflected sound waves are captured and converted into real-time images displayed on a video monitor. It is important to report CPT® code 93319 separately in addition to the primary echocardiography imaging code when this procedure is performed.

1. Indications

The 3D echocardiographic imaging procedure is indicated for the assessment of various cardiac structures and functions, particularly in patients with congenital cardiac anomalies. The specific indications include:

  • Assessment of Cardiac Chambers Evaluation of the size and function of the heart's chambers, which is crucial for diagnosing and managing heart conditions.
  • Evaluation of Cardiac Valves Detailed examination of the heart valves to identify any abnormalities or dysfunctions that may affect cardiac performance.
  • Left Atrial Appendage Assessment Analysis of the left atrial appendage, which is important for understanding the risk of thrombus formation and stroke.
  • Interatrial Septum Examination Inspection of the interatrial septum to detect any defects or anomalies that could impact blood flow between the atria.
  • Interventricular Septum Analysis Assessment of the interventricular septum for structural integrity and function, which is vital in congenital heart disease.

2. Procedure

The procedure for 3D echocardiographic imaging involves several key steps to ensure accurate assessment of cardiac structures. These steps include:

  • Transducer Selection The appropriate transducer is selected based on the patient's age and size. For pediatric patients, a small, high-frequency transducer is often used, while adult patients may require a larger transducer.
  • Patient Positioning The patient is positioned appropriately, either in a supine or left lateral decubitus position, to optimize the imaging angles and access to the heart.
  • Image Acquisition The transducer is placed on the chest (transthoracic echocardiography) or passed through the mouth into the esophagus (transesophageal echocardiography). The transducer emits ultrasound waves that penetrate the heart, and the reflected waves are captured to create images.
  • Real-Time Imaging As the heart beats, real-time 3D images are generated, allowing for dynamic visualization of cardiac structures and functions.
  • Post-Processing The acquired 3D dataset undergoes extensive computer post-processing to enhance image quality and provide detailed evaluations of cardiac morphology and function.

3. Post-Procedure

After the 3D echocardiographic imaging procedure, patients may be monitored for any immediate post-procedural effects, especially if transesophageal echocardiography was performed. Patients are typically advised to rest and may be observed for a short period to ensure there are no complications. The results of the echocardiographic assessment are then analyzed, and a report is generated to guide further clinical decision-making. Follow-up appointments may be scheduled to discuss findings and any necessary interventions based on the assessment results.
