RESUMEN
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 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.

Anomalous left coronary artery from the pulmonary artery (ALCAPA) was described by Abbott in 1908. In most cases, it is an isolated lesion, being the most common cause of myocardial ischemia in children. The associated mortality rate without intervention reaches 90% during childhood. We report the case of a 67-year-old woman, who underwent coronary angiography for investigation of atypical chest pain and was found to have ALCAPA. The patient refused surgery and has remained asymptomatic on a medical regimen.

We report the case of 24-year-old woman who presented with ductal aneurysm 7 years after a triple ligation of a patent ductus arteriosus. She underwent successful repair through median sternotomy and under moderate hypothermic circulatory arrest and selective cerebral perfusion.
