A case of abnormal chordae of the mitral valve (MV) associated with systolic anterior motion (SAM) is not commonly encountered in clinical practice. Here we report MV repair via the edge-to-edge technique in a 56-year-old male with MV regurgitation associated with papillary muscle displacement and posterior leaflet prolapse. Echocardiography revealed obstruction of the left ventricular outflow ...
The septomarginal trabecula is present in all human hearts as well as in the hearts of other primates. It usually connects the interventricular septum with the anterior papillary muscle, although there are many variations in how this is achieved. The object of the analyses was to estimate the bilateral topography of the septomarginal trabecula and the anterior papillary muscle in the context of...
BACKGROUND Papillary muscle rupture is one of the catastrophic mechanical complications following myocardial infarction. Rupture leads to acute mitral valve regurgitation, pulmonary edema, and cardiogenic shock. Survival is dependent on prompt recognition and surgical intervention. CASES REPORT We present two cases where acute myocardial infarction was complicated by papillary muscle rupture ...
BACKGROUND Solitary papillary muscle (PM) hypertrophy is an unique type of hypertrophic cardiomyopathy (HCM), which is characterized by predominant papillary muscle hypertrophy sparing the rest of other left ventricular segments. It has recently drawn our attention about the mechanism of left ventricular mid-cavity obstruction and the influence of pressure gradient in the left ventricular outfl...
ince the introduction of transvenous cardiac pacing S by Furman and Schwedell in 1959, numerous reports of unusual complications have appeared. To o w knowledge, rupture of a papillary muscle o r any valvular component has not been reported previously. This report describes a case of mitral valve papillary muscle rupture upon removal of a transvenous pacing electrode. Furthermore, this patient ...
BACKGROUND Ischemic mitral regurgitation (MR) relates to displacement of the papillary muscles from ischemic ventricular distortion. We tested the hypothesis that repositioning of the papillary muscles can be achieved by injection of polyvinyl-alcohol (PVA) polymer, a biologically inert biomaterial that has been specially formulated to produce an encapsulated, stable, resilient gel once injecte...
