Abstrakt: Purpose: Delineate retrospectively and prospectively the incidence and characteristics of transient ST-segment elevation during transseptal puncture.
Methods: The study retrospectively evaluated 307 patients from January 1, 2015, to December 31, 2017, and prospectively evaluated 231 patients from January 1, 2018, to July 31, 2019.
Results: The presence of ST-segment elevation was significantly higher in the prospective sample than in the retrospective sample (5.2% vs. 1.3%, p < 0.05). Between the two groups, there was no significant difference in age, sex, comorbidities, left atrial volume index, and the etiology of atrial fibrillation among patients with ST-segment alteration. In all patients, the ST-segment elevation was observed in the inferior wall derivations, except for one patient with ST elevation in lead I, AVL, V1-V4 during the septal puncture, associated with sinus bradycardia and reversed hypotension with intravenous fluids. Comparative analysis of the systolic and diastolic arterial pressure and the minimum heart rate during the phenomenon demonstrated more severity in the retrospectively evaluated population than in the prospective population. There was a significant association between the occurrence of ST-segment elevation > 2 mm and the presence of symptoms. In these patients, coronary angiography showed no alterations. Atropine was administered to one patient who presented with junctional bradycardia after the puncture. This medication reversed the situation.
Conclusion: ST-segment elevation is a short-term phenomenon that can occur during transseptal catheterization without clinically evident symptoms. The catheter ablation procedure can be safely concluded despite the occurrence of the phenomenon.
