the most frequent congenital heart defects in the neonatal period are ventricular septal defects. ventricular septal aneurysms can rarely develop from an interventricular septal (ivs) defect in adults. we describe a 47-year-old man with an aneurysm in the ivs growing towards the right ventricle, which was confirmed by cardiac computed tomographic angiography and was missed by echocardiography.

Elastin insufficiency predisposes to elevated pulmonary circulatory pressures through changes in elastic artery structure.

Journal: :Journal of applied physiology 2008

Adrian Shifren Anthony G Durmowicz Russell H Knutsen Gilles Faury Robert P Mecham

Elastin is a major structural component of large elastic arteries and a principal determinant of arterial biomechanical properties. Elastin loss-of-function mutations in humans have been linked to the autosomal-dominant disease supravalvular aortic stenosis, which is characterized by stenotic lesions in both the systemic and pulmonary circulations. To better understand how elastin insufficiency...

We report a case of right ventricular (RV) diastolic dysfunction due to a large hematoma posterior to the left ventricle (LV) after cardiac surgery. An 80-year-old woman underwent cardiac surgery. After surgery, her physical findings revealed right heart failure. Localized hematoma posterior to the pericardial space and the RV compression to the sternum were shown by computed tomography. Transt...
