3D Electro-Anatomical Mapping is an advanced imaging and mapping technology used during the diagnosis and catheter ablation of heart rhythm disorders. How is 3D Electro-Anatomical Mapping applied, and in which situations is it used? Get detailed information with the evaluations of Prof. Dr. Osman Beton.

3D Electro-Anatomical Mapping

Accurate evaluation and treatment of heart rhythm disorders have become possible today not only with experienced electrophysiology teams, but also through the use of advanced technologies. Especially in complex rhythm disorders, analyzing the electrical conduction system of the heart in detail is one of the factors directly affecting treatment success. 3D Electro-Anatomical Mapping is one of the advanced electrophysiology technologies that enables the simultaneous evaluation of the electrical activity and anatomical structure of the heart.

These systems used during catheter ablation help identify electrical foci or abnormal conduction pathways causing rhythm disorders with high accuracy by creating a three-dimensional digital model of the heart. Thus, catheter movements can be navigated more precisely, target regions can be analyzed in detail, and the ablation procedure can be planned on a personalized basis. It ranks among the technologies providing significant advantages, particularly in the treatment of atrial fibrillation, atrial flutter, supraventricular tachycardia (SVT), ventricular tachycardia, and complex rhythm disorders.

In electrophysiological procedures performed at MediHeart Medical Center Güzelyurt Cardiology Department, advanced mapping technologies are utilized by Prof. Dr. Osman Beton according to the patient’s clinical characteristics. The goal in treatment planning is to identify the source of the rhythm disorder most accurately, plan interventional treatment more precisely, and support patient safety.

What is 3D Electro-Anatomical Mapping?

3D Electro-Anatomical Mapping is a computer-assisted advanced imaging and navigation system used in the electrophysiology laboratory. During the procedure, a three-dimensional digital heart model is created by combining electrical signals obtained from the inner surface of the heart with anatomical data.

Thanks to this technology, electrical foci causing rhythm disorders, abnormal conduction pathways, and scar tissues can be visualized in detail. Thus, catheter ablation can be planned in a more targeted manner, aiming to reduce unnecessary energy applications.

In Which Situations is 3D Electro-Anatomical Mapping Used?

This technology is not a standalone treatment method. It is an auxiliary advanced imaging system used during electrophysiological study (EPS) and catheter ablation.

It can generally be used in the following situations:

• Atrial fibrillation ablation

• Pulmonary vein isolation

• Atrial flutter ablation

• Supraventricular tachycardia (SVT) ablation

• Ventricular tachycardia ablation

• Evaluation of complex rhythm disorders

• Re-intervention planning in patients who have previously undergone ablation

The mapping system to be used and the procedure plan are determined according to the characteristics of the patient’s rhythm disorder.

Which Evaluations Are Performed Before the Procedure?

A detailed cardiological evaluation is performed prior to electrophysiology procedures in which mapping technology will be used.

When deemed necessary;

• Cardiology examination

• Electrocardiography (ECG)

• Holter rhythm recording

• Echocardiography

• Blood tests

• Electrophysiological evaluation

• Cardiac CT or Cardiac MRI

• Transesophageal Echocardiography (TEE) when required

  can be applied.

  Thanks to these evaluations, both patient safety is enhanced and the necessary procedure planning for the three-dimensional mapping system is established.

How is 3D Electro-Anatomical Mapping Applied?

The procedure is applied during catheter ablation or Electrophysiological Study (EPS) performed in the electrophysiology laboratory. Thin catheters placed through the vein in the groin area are advanced to the heart, and the electrical activity of the heart is simultaneously recorded through specialized sensors.

The mapping system creates a three-dimensional anatomical model of the heart using the data obtained from the catheters. In this way, regions causing rhythm disorders can be identified with millimeter precision. In line with this information, catheter ablation can be performed in a more targeted manner.

Procedure duration may vary depending on the type of rhythm disorder, the scope of the ablation to be applied, and the patient’s cardiac anatomy.
