Case Report: Chylopericardium after Heart Transplantation due to Lymphatic Malformation in a Patient With Noonan Syndrome

Tatiana Costa Diamantino Vaz et al. Transplant Proc. 2025 Sep.

Abstract

Chylopericardium is a rare condition, typically associated with the postoperative period following cardiac surgery, lymphatic system obstruction, or congenital malformations. We report the case of a school-aged child with Noonan syndrome who developed treatment-resistant chylopericardium after undergoing heart transplantation. Further investigation revealed an anomalous lymphatic system.
