ABSTRACT
Abstract Mitral valve aneurysm is a rare and uncommon complication of infective endocarditis leading to a weakened mitral tissue. The most feared mitral valve aneurysm's complications are perforation and severe mitral regurgitation. Multiple mechanisms have been suggested to explain the development of mitral valve aneurysm in aortic infective endocarditis including local extension of the infection, the mitral kissing vegetation and aortic regurgitation. We report the case of a 29-year-old man who had infective endocarditis of a native aortic valve and the sub-aortic diaphragm complicated by a perforated mitral valve aneurysm diagnosed only by transesophageal echocardiogram. The patient had no sign of heart failure. We hypothesized that all those mechanisms lead to the developing of the mitral valve aneurysm in this case, but also the presence of the diaphragm favored the spread of the infection.
RESUMEN
Resumen Una de las complicaciones poco comunes e inusuales de la endocarditis infecciosa son los aneurismas de la válvula mitral. Las complicaciones más temidas de estos últimos son la perforación y la insuficiencia mitral severa. Diferentes mecanismos pueden explicar el desarrollo de dicha insuficiencia en el contexto de una endocarditis infecciosa, incluyendo una extensión local, una vegetación sobre la válvula mitral y una insuficiencia aórtica. Nuestro caso clínico es el de un joven de 29 años diagnosticado de endocarditis infecciosa sobre su válvula aortica nativa con un diafragma subaortico complicado con un aneurisma de la válvula mitral perforado. El paciente no presentaba signos de insuficiencia cardíaca. Hemos supuesto que todos los mecanismos que hemos evocado anteriormente han llevado al desarrollo de dicho aneurisma, junto con la presencia del diafragma, elemento en favor de la diseminación de la infección.
