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 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.

The interventricular septal dissection is an uncommon, and is occasionally associated with sinus of Valsalva aneurysm. A spontaneous dissection with a normal sinus of Valsalva is extremely rare and is mostly a result of a congenital defect. We report the case of a 23-year-old male admitted for complete heart block and presenting as an incidental finding during the TTE multiple and huge cystic-like mass in the interventricular septum (IVS) which is the TTE characteristic of IVS dissection. Most patients remain asymptomatic until the anatomical and hemodynamic changes lead to complications like: severe aortic regurgitation with heart failure and conduction abnormalities. Although transthoracic echocardiogram (TTE) has been the first-line imaging modality for such findings, cardiac computed tomography (CT) and magnetic resonance imaging have been increasingly used as supplemental or confirmatory tests. The imaging modalities showed a perforation of right sinus of Valsalva causing the expansion of the dissection to the apex. The patient underwent surgical repair with satisfying results. In conclusion, we report an extremely rare clinical case of spontaneous dissection of the interventricular septum using multiple imaging techniques and with a successful surgery.

Aluminium phosphide (ALP) is widely used as a fumigant pesticide. In case of ALP poisoning, it is responsible for myocardial dysfunction, related to toxic myocarditis, and hemodynamic disorders. We report a case of a 28-year-old female who had intentionally ingested ALP and was admitted with cardiogenic shock. The transthoracic echocardiography (TTE) at the time of admission showed severe global myocardial hypokinesia with the presence of a giant left ventricular thrombus. Cardiovascular magnetic resonance (CMR) revealed extensive toxic myocarditis with a left ventricular systolic dysfunction. All cardiac lesions were reversible after symptomatic treatment, within 6 months. We aim, by reporting this case, to evidence the complete reversibility of cardiac injury due to aluminium phosphide poisoning documented by transthoracic echocardiography and cardiovascular magnetic resonance.
