Differential biomarker responses of hemolysis, inflammation, and myocardial injury after pulsed-field pulmonary vein isolation: balloon-in-basket vs. circular catheter systems
Clinical Report: Comparative Analysis of Biomarker Variations in Hemolysis, Inflammation, and Myocardial Damage Following Pulsed-Field Pulmonary Vein Isolation
Overview
This study compares the biological impact of balloon-in-basket and circular catheter approaches in pulsed-field pulmonary vein isolation (PVI). Both systems induced significant increases in biomarkers of hemolysis, inflammation, and myocardial injury, with notable differences in haptoglobin levels and renal function stability.
Background
Pulsed-field ablation (PFA) is a novel non-thermal technique for pulmonary vein isolation, essential in managing atrial fibrillation (AF). Understanding the systemic effects of different PFA technologies is crucial for optimizing patient outcomes and minimizing complications. This study provides insights into the biomarker responses associated with two distinct PFA catheter designs.

Key Findings
Both PFA systems caused significant increases in leukocytes, CRP, LDH, troponin, and CK without inter-group differences.
BiB required fewer applications compared to PS (16 vs. 32, p < 0.001).
Haptoglobin decreased significantly in both groups, with a more pronounced decline in the PS group (Δ −13 vs. −4 mg/dL, p = 0.090).
Renal function remained stable overall, with one PS patient developing acute kidney injury.
Δ-Hemoglobin correlated inversely with application number in the BiB group (p = 0.046).
Δ-Troponin and Δ-CK correlated positively in the PS group (p < 0.05).
Clinical Implications
Clinicians should be aware of the comparable systemic effects of both PFA systems on biomarkers of hemolysis and myocardial injury. The differences in haptoglobin levels and the isolated acute kidney injury in the PS group may influence catheter selection and patient management strategies during PVI.
Conclusion
This comparative analysis highlights the need for further investigation into the biomarker responses of different PFA technologies. Understanding these differences may enhance clinical decision-making in the treatment of atrial fibrillation.
