Cardiac arrhythmia is a disturbance in the normal rhythm of the heart, where the heartbeat may be abnormally fast or slow, or irregular. This condition can affect the efficiency with which the heart pumps blood to the body and seriously compromise the patient’s health. Dr. César Peralta, cardiologist and electrophysiologist at the Clinica Ricardo Palma, offers a detailed explanation of the Three-Dimensional Mapping System Ablation, an advanced procedure for the effective and safe treatment of cardiac arrhythmias.

What is Three-Dimensional Mapping System Ablation?

It is a minimally invasive procedure, as no cuts are made to reach the heart’s electrical circuit. The 3D mapping system allows the specialist to identify the electrical circuit responsible for the arrhythmia and eliminate it with great precision by creating a three-dimensional reconstruction of the heart and its electrical system.

In which cases is 3D Mapping System Ablation indicated?

This procedure is recommended for patients with cardiac arrhythmias, especially those who suffer from tachycardias (heart accelerations) or irregular heartbeats, and in whom medications have failed to control the arrhythmia. Ablation with a three-dimensional mapping system is both a diagnostic and therapeutic method, since it makes it possible to locate the origin of the arrhythmia and treat it simultaneously.

How is this procedure performed?

As this is a minimally invasive procedure, small punctures are made in the groin region to access the main veins leading to the heart. These veins serve as a “tunnel” to introduce special catheters equipped with sensors that detect the heart’s electrical signals. Once the electrical circuit causing the arrhythmia has been identified, radiofrequency energy is used to eliminate it, a process known as ablation.

Does it require any preparation?

As in any surgical procedure, it is necessary to perform preoperative examinations to ensure that the patient is fit to undergo the intervention.

How long does it last?

The performance of 3D Mapping System Ablation varies according to the arrhythmia to be treated. It can last from 30 minutes to three or four hours, depending on the complexity of the case.

What are the benefits to the patient after this procedure?

The main benefit of 3D ablation is the elimination or modulation of tachycardia, resulting in a marked improvement in arrhythmia-related symptoms such as palpitations, fatigue, dizziness and fainting. This not only improves the patient’s quality of life but may also prevent long-term complications.

What aftercare should be provided?

After the procedure, patients are usually discharged the following day. They are advised to avoid strenuous exercise for a few days to protect the puncture sites and ensure adequate recovery.
