The role of ventricular tachycardia ablation (VTA) in CS has been investigated in a few small, single-center, and larger observational studies, but the evidence still needs to be provided. This study aimed to investigate the clinical outcomes of VTA in patients with CS admitted with a diagnosis of VT.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A retrospective analysis was conducted using the TriNetX database: US collaborative network from 2010 to 2024. Patients undergoing ablation for VT with and without CS were identified. Two groups were created for propensity score analysis matching a history of hypertension, diabetes, obesity, peripheral vascular diseases, heart failure, ischemic heart diseases, atrial fibrillation, and chronic kidney disease. The primary outcome was the incidence of death, cardiogenic shock, heart failure, acute myocardial infarction, hemorrhagic stroke, ischemic stroke, and ventricular tachycardia within 1 year from the date of the index procedure.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Out of 15,958 patients who underwent catheter ablation for VT, 778 patients had CS. After propensity matching, the mean age of patients with VT and CS who underwent ablation was 58.6 (SD = 11.3), compared to 59.5 (SD = 13) in patients with VT without CS (p-value = 0.07). The propensity-matched analysis showed no significant differences in procedure-related complications between those with cardiac sarcoidosis (CS) and those without. Both cohorts had 10 events each for cardiac tamponade (p = 0.195), groin hematoma requiring transfusion (p = 0.102), pneumothorax (p = 0.317), and sepsis (p = 0.654).

Cardiogenic shock was also similar, with 13 events in the non-CS group and 12 in the CS group (HR = 0.879, 95% CI 0.636-1.213, p = 0.430).

There was no significant difference in ICD shock (147 in non-CS vs. 185 in CS, HR = 0.817, 95% CI 0.658-1.014, p = 0.066), ischemic stroke (10 cases each, HR = 0.941, 95% CI 0.382-2.316, p = 0.895), or hemorrhagic stroke (10 cases each, HR = 1.455, 95% CI 0.326-6.501, p = 0.620).
