24th ASMIHA Coverage: VT Ablation
JAKARTA --- As one type of tachycardia cause of sudden death, ventricular tachycardia (VT) has led to 1 in 1000 death. This interesting topic raised in the workshop "VT Ablation: who, how, when? " by Dicky A. Hanafy, MD. The material the latest handling of ventricular tachycardia, namely the use of VT ablation technique. VT ablation procedures performed by electrophysiologist, aiming to eliminate the re-entry area VT is the cause of the patients. Currently, there is no guideline in performing ablation of VT but only based on consensus.
Experts issued by the European Heart Rhythm Association (EHRA) and the Heart Rhythm Society (HRS). Indications for VT ablation in patients with structural heart disease and nonstructural are different. In patients with disease structural heart, symptomatic sustained monomorphic VT (SMVT) antiarrhythmic not corrected by drugs, premature ventricular contractions (PVC), SMVT recurrent disease.
Primary myocardial infarction with ejection fraction less than 30% have became an indicator. Meanwhile, indications for patients with heart disease nonstructural is idiopathic VT, heavy VT monomorphic, monomorphic VT which can not be cured by antiarrhythmic, VT in irreversible etiolgy, and so forth.
In performing VT ablation, we need to identify and modify scar causing arrhythmias by using the mapping method. "The use of mapping in managing ventricular tachycardia is to looking for the origin of arrhythmias, "said Dicky A. Hanafy, MD. Recent methods of mapping and ablation permits ablation during sinus rhythm state. However, the method of ablation of VT in patients with structural cardiac disorders needs to be done as soon as possible to prevent recurrent VT and multiple shock that can cause psychological trauma. Early management of VT can prevent complications in patients. Thus, knowing indications and timing of VT ablation is important to heal as well as improving quality of life in patients.
