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.</p><p><strong>Methods: </strong>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.</p><p><strong>Results: </strong>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 occurred in 13 patients in the non-CS group versus 12 in the CS group (p = 0.840). At the 1-year follow-up, there was no significant difference in the mortality rate between the two groups (HR = 1.228, 95% CI 0.834-1.809, p = 0.298). 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). However, CS was associated with a higher risk of acute exacerbation of heart failure (314 in non-CS vs. 378 in CS, HR = 0.823, 95% CI 0.709-0.956, p = 0.010) and a lower risk of acute myocardial infarction (96 in non-CS vs. 74 in CS, HR = 1.389, 95% CI 1.026-1.881, p = 0.033). 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).

Maintenance of lead position is a key element for proper functioning of the CIEDs. There are two suturing techniques that are commonly used to anchor the leads to pectoral muscle (simple knot and anchor knot techniques).

The leads stabilized by the simple knot technique (three rabbits) maintained their position in the acute term, two of them were dislocated under traction and only one of them was found to be partially resistant to at least 10 N of traction force. 0.5 cm of dislocation was observed between that lead and its sleeve after applying traction. Only two leads (50%) stabilized by using the simple knot technique in chronic term remained their position. Lead and sleeve dislocated together in one subject, while the other lead was found separately dislocated from its sleeve. One of the two other leads was resistant to at least 10 N of traction force and that lead remained in stable in sleeve. Muscle biopsy specimens of eight rabbits were evaluated for necrosis.
