Case Report:A Rare Case of Left Atrial Aneurysm Following Isolated Staphylococcal Pericarditis in a Paediatric Patient Presenting as Constrictive PericarditisOA

Left atrial aneurysm is an exceptionally rare condition,particularly in the pediatric population,and even more so as a sequela of bacterial pericarditis.We present the case of a 16-month-old girl who developed a left atrial aneurysm following isolated Staphylococcus aureus pericarditis.She initially presented in decompensated shock and was later diagnosed with constrictive pericarditis.Despite undergoing pericardiectomy,she subsequently developed a left atrial aneurysm,necessitating surgical closure.This case highlights the aggressive nature of bacterial pericarditis and its potential to cause rare structural cardiac complications.
