Gerbode Defect With Concomitant Aortic Root Pseudoaneurysm Caused by Destructive <i>Streptococcus agalactiae</i> Endocarditis

The Gerbode defect is a rare left ventricle-to-right atrium shunt caused by an anatomic deficiency of the membranous septum. Infective endocarditis is one of the main etiologies for Gerbode defect. This manuscript presents a rare case of Gerbode defect secondary to Streptococcus agalactiae endocarditis. Transthoracic echocardiography visualized the Gerbode defect. Cardiac computed tomography and 3D reconstruction delineated the anatomy. This multimodality imaging approach was pivotal in early diagnosis and guiding successful surgical planning.
