OBJECTIVE To evaluate the prevalence of plaque erosion as a substrate for coronary thrombosis. DESIGN Pathological study in patients with acute myocardial infarction not treated with thrombolysis or coronary interventional procedures. PATIENTS 298 consecutive patients (189 men, mean (SD) age 66 (11) years; 109 women, 74 (8) years) dying in hospital between 1984 and 1996 from acute myocardia...

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...

Tendon rupture in dogs is generally the result of a direct trauma. This report described the use of adjacent muscle autogenic fascial graft for reconstruction of distal rupture of long digital extensor tendon in a dog. A two-year-old male mix breed dog, was presented with a non-weight bearing lameness of the right hind limb and a deep rupture of lateral side of right tarsus. History taking reve...

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...

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...
