Direct Insertion of the Papillary Muscle into the Anterior Mitral Leaflet: Cadaveric Findings
Direct insertion of the anterior papillary muscle (DPM) into the mitral valve is uncommon. During the routine dissection of an adult female, a DPM into the mitral valve with abnormal chordae tendinae was observed. This abnormal papillary muscle was measured as 28.0 mm in length from myocardial to insertion, 14.8 mm in width, and 7.0 mm in depth. The embryology, symptoms, associated cardiac dise...
متن کاملPericardial Effusion in an Extreme Low Birth Weight Neonate with Peripherally Inserted Central Catheter
Background: Pericardial effusion and cardiac tamponade are the rare complications of peripherally inserted central catheters (PICC insertion) in extreme low birth weight infants. In this regard, paying attention to these complications is of utmost importance, because they can result in infant death. Case report: The case of our infant is a sa...
متن کاملDisplacement of the Mid-Papillary Muscles Between End-Systole and End-Diastole Serves as a New Marker of Ventricular Twist and Translation
The normal left ventricular (Lv) wall twists (apex relative to base) 12-14 degrees during ejection. The papillary muscles (PM) and chordae tendenae are force transducing elements between the LV chamber and the mitral annulus. We hypothesize that relative PM displacement and rotation (in short-axis views) is coupled to LV torsion. In ten normal subjects, PM position was measured at end-systole a...
متن کاملDigeorge syndrome presenting with uncommon cardiac anomaly and hepatomegaly
Digeorge syndrome is caused by microdeletion of a large region of chromosome 22q11.2 lead to the abnormal development of the third and fourth pharyngeal pouches. This syndrome is characterized by hypoparathyroidism, cellular immune deficiency secondary to thymic hypoplasia, congenital heart disease and dysmorphic facial features. In this case report, we describe a 4month old boy who presented w...
متن کاملCross sectional echocardiographic demonstration of the mechanisms of abnormal interventricular septal motion in congenital total absence of the left pericardium.
OBJECTIVE To investigate the influence of the absence of the pericardium on the left ventricular wall, particularly on interventricular septal motion, using M mode and cross sectional short axis echocardiography in patients with congenital total absence of the left pericardium. METHODS 21 patients with, congenital total absence of the left pericardium were divided into three groups according ...
