Cryoablation
Heart rhythm disorders (arrhythmias) are cardiological diseases that occur as a result of irregularities developing in the electrical conduction system of the heart and can significantly affect quality of life. While these rhythm disorders, which can present with symptoms such as palpitations, irregular heartbeats, shortness of breath, dizziness, rapid fatigue, and fainting, can be controlled with medication in some patients, interventional treatment methods may be required in certain cases. Cryoablation is one of the advanced interventional cardiology treatments aimed at neutralizing electrical foci that cause rhythm disorders by using controlled cold energy.
During cryoablation, the target area is reached with the help of special catheters, and a controlled freezing process is applied at very low temperatures. In this way, it is aimed to isolate the abnormal electrical conduction pathways causing the rhythm disorder from the normal electrical system of the heart. Widely used as one of the methods for pulmonary vein isolation, especially in the treatment of atrial fibrillation, cryoablation is among the effective treatment options in suitable patient groups. However, since it may not be suitable for every patient, the treatment plan is established after a detailed cardiological evaluation.
At MediHeart Medical Center Güzelyurt Cardiology Department, Cryoablation procedures are planned by our Cardiology Specialist Prof. Dr. Osman Beton in accordance with the type of the patient’s rhythm disorder, cardiac structure, existing conditions, and current international electrophysiology guidelines. The objective is to determine the most appropriate and safest treatment method for every patient.
What is Cryoablation?
Cryoablation is a catheter ablation method that uses controlled cold energy instead of high heat in the treatment of heart rhythm disorders. During the procedure, special catheters generating cryoenergy are used to cool the target cardiac tissue to a specific temperature, aiming to neutralize the electrical conduction pathways causing the rhythm disorder.
One of its most common areas of use is the treatment of atrial fibrillation. In addition, the cryoablation method may also be preferred in certain supraventricular tachycardias deemed suitable and other selected rhythm disorders. The ablation technique to be utilized is determined by the cardiology specialist according to the clinical characteristics of the patient.
Who Can Undergo Cryoablation?
Cryoablation is not applied to every rhythm disorder patient. First, a detailed electrophysiological evaluation is performed to decide which treatment method is more suitable.
Cryoablation can be evaluated in the following patient groups:
Suitable patients diagnosed with atrial fibrillation
Individuals planned for pulmonary vein isolation
Rhythm disorder attacks persisting despite medical therapy
Certain types of supraventricular tachycardia
Patients for whom the cardiology specialist considers cryoablation suitable
The treatment plan is prepared entirely according to the type of the patient’s rhythm disorder and individual clinical characteristics.
Which Tests Are Performed Before the Procedure?
A detailed cardiological evaluation is conducted before planning cryoablation.
When deemed necessary:
Cardiology examination
Electrocardiography (ECG)
Holter rhythm recording
Echocardiography
Blood tests
Transesophageal Echocardiography (TEE)
Cardiac CT or Cardiac MRI
Electrophysiological evaluation
can be applied.
Thanks to these evaluations, both procedural safety is enhanced and the ablation technique to be applied is planned on a personalized basis.
How is Cryoablation Performed?
Cryoablation is an interventional cardiology procedure performed in the electrophysiology laboratory. Access to the heart is usually achieved with the help of thin catheters inserted through the vein in the groin area. When necessary, the left atrium is entered using a specialized transseptal crossing technique, and the target region is evaluated in detail.
With the help of a specialized cryoablation catheter or cryoballoon system, the target region is frozen in a controlled manner. During this procedure, the goal is to isolate the electrical conduction pathways causing the rhythm disorder. Pulmonary vein isolation via the cryoballoon method is one of the frequently applied techniques, particularly in atrial fibrillation treatment.
The duration of the procedure can vary depending on the type of rhythm disorder, the technique to be applied, and the anatomical characteristics of the patient. After the procedure is completed, patients are kept under observation for a specific period, and discharge is planned according to their general health status.
What Are the Advantages of Cryoablation?
Cryoablation is one of the catheter ablation methods evaluated as effective in the treatment of heart rhythm disorders in suitable patient groups. Due to its application using controlled cold energy, it ranks among the preferred interventional treatment options, especially in specific rhythm disorders. However, obtaining the same clinical outcome in every patient cannot be guaranteed. The treatment plan is established entirely by considering the type of the patient’s rhythm disorder and individual characteristics.
In suitable patients, cryoablation:
Can contribute to reducing atrial fibrillation attacks.
Can help alleviate complaints such as palpitations, shortness of breath, and decreased exercise capacity.
Can support maintaining normal sinus rhythm of the heart.
Can contribute to performing pulmonary vein isolation effectively.
Can support improving daily quality of life.
Can allow for the reevaluation of the need for rhythm-regulating medications in certain patients.
Results to be obtained from the treatment can vary based on many factors such as the duration of the rhythm disorder, the presence of structural heart disease, accompanying chronic conditions, and regular follow-up.
Are There Risks of Cryoablation?
Cryoablation is considered among safe interventional cardiology procedures when performed by experienced electrophysiology teams. Nevertheless, as with any interventional procedure, certain risks cannot be completely eliminated.
Conducting a detailed evaluation of the patient before the procedure, reviewing existing conditions, and applying necessary imaging methods help reduce potential risks. All necessary precautions are taken throughout the procedure regarding bleeding or bruising related to the access vein site, transient rhythm changes, and other rarely observed complications. In treatment planning, expected benefits and potential risks are evaluated together to determine the most appropriate approach for the patient.
Post-Procedure Recovery Process
After cryoablation, patients are kept under observation for a specific period. The discharge time can vary based on the scope of the applied ablation, the general health status of the patient, and post-procedural findings.
In the initial weeks, regular usage of medications recommended by the cardiology specialist is important. Particularly, the duration of use for blood thinners and necessary rhythm-regulating therapies is planned on an individual basis. Heart rhythm is regularly evaluated through follow-up examinations, and the treatment process can be adjusted when necessary.
Transient rhythm irregularities may be observed during the initial months following ablation. This condition does not always signify treatment failure and must strictly be evaluated by a cardiology specialist.
Importance of Experience in Cryoablation
The cryoablation procedure is one of the interventional cardiology applications that require advanced electrophysiology infrastructure, an experienced team, and detailed procedural planning. Accurate evaluation of pulmonary vein anatomy, proper catheter selection, and application of ablation at the correct sites are among the critical factors affecting treatment success.
At MediHeart Medical Center Güzelyurt Cardiology Department, Prof. Dr. Osman Beton decides on the necessity of cryoablation by evaluating patients’ clinical findings, ECG and Holter recordings, echocardiography results, and other imaging methods in detail. The treatment process is planned on a personalized basis in line with current international electrophysiology guidelines.
