Anterolateral papillary muscle rupture: an unusual complication of septic coronary embolism

, : Anterolateral papillary muscle rupture: an unusual complication of septic coronary embolism. European Journal of Echocardiography 12(2): E10-E10

In most cases, acute mitral valve regurgitation in the setting of infective endocarditis is caused by the destruction of either the mitral valve leaflets or the chordal apparatus. A 54-year-old woman had development of respiratory failure due to pulmonary oedema from severe acute mitral valve regurgitation in the setting of acute bacterial endocarditis. She was found to have a ruptured anterolateral papillary muscle from occlusion of the circumflex artery by embolic vegetations arising from the aortic valve. Although this occurrence is uncommon, an embolic phenomenon resulting in myocardial infarction and subsequent rupture of papillary muscle must be considered as a cause of acute severe mitral valve regurgitation.

Vasodilator and vasodepressor properties of angiotensins have been reported, and mediation by prostaglandins or nitric oxide has been proposed. Other studies indicate that angiotensin AT(2) receptors might mediate a depressor action, and the prese...

We consider a simple model of quantum disorder in two dimensions, characterized by a long-range site-to-site hopping. The system undergoes a metal–insulator transition--its eigenfunctions change from being extended to being localized. We demonst...
