Natriuretic Peptides After Left Atrial Appendage Amputation

Influence of Left Atrial Appendage Amputation on Natriuretic Peptides - a Randomized Controlled Trial

Surgical amputation of the left atrial appendage (LAA) is an established intervention during surgical atrial fibrillation (AF) therapy. However, its effects on the endocrine function of the left atrium are unclear. This study aims to quantify the serum levels of natriuretic peptides in patients who undergo concomitant surgical AF ablation with or without LAA amputation.

Inclusion Criteria:

• Indication for concomitant AF therapy during cardiac surgery with cardiopulmonary bypass

Exclusion Criteria:

• Lack of informed consent
