A rare case of partial Shone complex in adulthood: coarctation-site methicillin-sensitive <i>Staphylococcus aureus</i> endocarditis and saccular aneurysm

This case highlights a rare adult manifestation of partial Shone complex complicated by coarctation of the aorta-site methicillin-sensitive Staphylococcus aureus infection, saccular aneurysm formation, and recurrent graft-associated infective endocarditis. The clinical course underscores the importance of vigilant multimodality imaging, early multidisciplinary evaluation, and long-term follow-up in adults with complex CHD, particularly when infectious complications are present.
