Background: Initial clinical studies of pulsed field ablation (PFA) to treat atrial fibrillation (AF) indicated a >90% durability rate of pulmonary vein isolation (PVI). However, these studies were largely conducted in single centers and involved a limited number of operators. The electrophysiological findings and outcomes in patients undergoing repeat ablation after an initial PF ablation for AF are incompletely understood.

Detection of granuloma in histopathological evaluation proves the diagnosis, but endomyocardial biopsy (EMB) is associated with a high sampling error. However, prompt immunosuppressive therapy may significantly affect patient's prognosis.

- The study aimed to assess the effectiveness of non-invasive programmed ventricular stimulation (NIPS) and programmed ventricular stimulation (PVS) after ventricular tachycardia (VT) ablation in predicting the likelihood of VT recurrence.
- Out of 138 patients, a significant 75% were found to be non-inducible for VT, and the findings indicated that a normal NIPS significantly correlated with lower VT recurrence rates compared to inducible cases.
- NIPS demonstrated better predictive values for assessing patient risk, particularly among individuals with ischemic cardiomyopathy (ICM) and left ventricular ejection fraction (LVEF) greater than 35%, marking it as a valuable tool post-ablation.
Background: Patients undergoing ventricular tachycardia (VT) ablation often present with structural heart disease (SHD) and reduced ejection fraction. Inducing VT by programmed electrical stimulation (PES) puts these patients at risk for hemodynamic instability and cerebral hypoperfusion.
Objective: The present study screens for cerebral oxygen desaturation phases (ODPs) in patients undergoing VT ablation.
Article Synopsis
- Pulsed field ablation (PFA) is a new method for treating atrial fibrillation (AF) that focuses on ablating heart tissue while minimizing harm to nearby structures.
- In the MANIFEST-17K study, data from 106 centers involved 17,642 patients and showed no serious complications like esophageal damage, with only a 1% major complication rate.
- The results suggest that PFA has a strong safety profile and may change how AF is treated, compared to traditional thermal ablation methods.
