Large Pseudoaneurysm of the mitral annulus as an infective endocarditis complication: a 3D echocardiography role in diagnosis and surgical procedure. Echocardiography (Mount Kisco, N.Y.), 31(8), E261–E263. https://doi.org/10.1111/echo.126440742-282210.1111/ECHO.12644https://hdl.handle.net/20.500.14352/131909In this report, we present the case of an 85-year-old patient with a recent history of an infective endocarditis (IE) referred to our hospital for severe mitral regurgitation. After closer observation, echocardiography showed a large pseudoaneurysm in the posterior mitral annulus opening into the left ventricle. Anatomical assessment by 2D and 3D transesophageal echocardiogram (TEE) was essential for a detailed morphologic characterization and surgical procedure delineation. This type of IE mitral periannular extension is uncommon and early surgical intervention is critical, however the outcome is still often adverse.engjournal article1540-8175https://doi.org/ 10.1111/ECHO.12644https://onlinelibrary.wiley.com/doi/10.1111/echo.12644restricted access616.123D transesophageal echocardiographyinfective endocarditispseudoaneurysmCardiología3205.01 Cardiología
