Looking down the atrioventricular canal

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...

Atrioventricular Canal Defect

IT is welcome to see a fourth edition of this useful textbook for students. The authors are to be congratulated on bringing out a further edition without notably increasing the length of this book, although their efforts to condense their material do lead to some difficulty. For example, on page 92, the 13 lines devoted to the natural history of breast cancer would almost certainly lead the stu...

[Persistent common atrioventricular canal].

T HIS PAPER was written first in 1960. At that time cases of the complete form of persistent common atrioventricular canal or endocardial cushion defect were regarded as consisting of an ostium primum defect of the atrial septum, a cleft in the anterior cusp of the mitral valve, a cleft in the septal cusp of the tricuspid valve, and an interventricular septal defect. Partial forms of the defect...

Complete atrioventricular canal

Complete atrioventricular canal (CAVC), also referred to as complete atrioventricular septal defect, is characterised by an ostium primum atrial septal defect, a common atrioventricular valve and a variable deficiency of the ventricular septum inflow. CAVC is an uncommon congenital heart disease, accounting for about 3% of cardiac malformations. Atrioventricular canal occurs in two out of every...
