Looking down the atrioventricular canal.
Down’s syndrome (DS) is the most common aneuploidy diagnosed in liveborn babies ( 1/700 live births). While DS is typically associated with recognizable dysmorphic features, clinical anomalies exhibit variable expressivity. The DS phenotype includes many organ systems and affects all three embryonic germ layers. DS is the most frequent chromosomal cause of mental retardation, is a recognized ge...
متن کاملSurgically created double-orifice left atrioventricular valve: a valve-sparing repair in selected atrioventricular septal defects.
OBJECTIVES Some features of the left atrioventricular valve (large mural leaflet, dystrophic tissue) represent a challenge for repair of atrioventricular septal defects without postoperative regurgitation. A retrospective study was conducted to evaluate the results of surgically creating a double-orifice left atrioventricular valve in such circumstances. Clinical results were analyzed according...
متن کاملDouble-orifice mitral valve associated with atrioventricular canal defects
A 4 year-old male presented with effort dyspnea, and was diagnosed as atrioventricular canal defects. This finding was confirmed by open heart surgery, and a congenital double orifice mitral valve was discovered. The septal defect was closed but the double orifice mitral valve was respected because of the absence of hemodynamic disturbance. We report this case with review of literature.
متن کاملReal-time wide-angle sector echocardiography: atrioventricular canal defects.
Real-time 800 phased-array two-dimensional sector echocardiography was used in 44 patients with atrioventricular (AV) canal defect. Anatomic details were surgically confirmed in 33. The apex view allowed visualization of atrial and ventricular portions of complete AV canal defects, with the common AV valve structures between the defects. The apex view also allowed us to differentiate divided an...
متن کاملGenome-Wide Association Study of Down Syndrome-Associated Atrioventricular Septal Defects.
The goal of this study was to identify the contribution of common genetic variants to Down syndrome-associated atrioventricular septal defect, a severe heart abnormality. Compared with the euploid population, infants with Down syndrome, or trisomy 21, have a 2000-fold increased risk of presenting with atrioventricular septal defects. The cause of this increased risk remains elusive. Here we pre...
