Endolymphatic seal for persistent secondary chyle leak following aortic valve replacement

Chylopericardium (CPE), a rare phenomenon characterized by chyle accumulation in the pericardial space, can arise from idiopathic or secondary causes. Although secondary CPE is often associated with various factors, including surgical trauma, malignancies, and infections, its occurrence following specific aortic valve replacement (AVR) remains underexplored.
