Atherosclerotic plaques may rupture without warning and cause acute cardiovascular syndromes such as heart attack and stroke. It is believed that mechanical forces play an important role in plaque progression and rupture. A three-dimensional (3D) MRI-based finite-element model with multicomponent plaque structure and fluid-structure interactions (FSI) is introduced to perform mechanical analysi...
Background Recent studies suggest that time series of healthy human interbeat intervals belong to a special class of bio-signals displaying multifractal properties. The breakdown of multifractality was observed in congestive heart failure and angina pectoris; however, there has been no attempt to evaluate multifractal behavior before and after beating heart myocardial revascularization (off-pum...
1 of 2 DESCRIPTION Rupture of mitral-aortic intervalvular fi brosa aneurysm is a rare complication of aortic valve endocarditis. 1 A 43-yearold man presented with persistent fever and progressive dyspnoea of 3 months duration. On admission, he was in fl orid pulmonary oedema and clinical examination showed fi ndings of severe aortic regurgitation. His electrocardiogram revealed complete heart b...
An acquired fistulous communication between the aorta and the right ventricle, caused by syphilitic infection and rupture of an aneurysmal dilation of the right sinus of Valsalva, has been reported by Tompkins (1941). Schuster (1937) made mention of a similar mycotic rupture. Mall (1912) attributed the giving way of the wall in this region to the presence of a congenital weakness. The anatomica...
