RESUMO
The mitro-aortic intervalvular fibrosa (MAIF) connects the anterior mitral leaflet to the posterior portion of the aortic annulus. The aneurysms of MAIF represent a complication of aortic valve endocarditis, but blunt chest trauma, aortic valve replacement and congenital heart disease have also been reported as a cause. We describe a case of an aneurysm of MAIF, whose progression was documented by serial echocardiographic observations. To the best of our knowledge, this very rare occurrence has not been reported previously.

Thoracic vein aneurysms are very rare vascular lesions, usually detected as incidental findings. We describe the case of a patient with an advanced atrioventricular block who underwent definitive pacemaker implantation. In order to explain the difficult advancement of a pacemaker lead, vein angiography was performed during the procedure and a large innominate vein aneurysm was observed. Successful lead placement was then performed without further complications.
