Atresia of the Left Atrioventricular Orifice
ثبت نشده
چکیده
The first well-documented case of Holmes heart associated with an atretic left atrioventricular orifice is reported. The Holmes heart may be considered as a single ventricle in which the main chamber has the morphologic characteristics of a left ventricle, the infundibular chamber is not inverted, and the great arteries are normally arranged. The importance of this report is greater than its simple description since it definitely establishes that coexistence of a true single ventricle and atresia of the atrioventricular orifice is possible.

SUMMARY A new case of an unusual association of mitral atresia with single left ventricle is reported. The salient anatomic features include: (1) the right atrioventricular valve is atretic; (2) the left atrioventricular valve enters the large ventricle with morpho-logic characteristics of the left ventricle; and (3) this large ventricle communicates by way of an interventricular communication ...
متن کاملAtresia of left atrioventricular orifice. Anatomical investigation in 62 cases.
Sixty-two hearts without a patent exit from the left atrium to the ventricular mass have been studied. All had situs solitus and laevocardia. The material consisted of 32 cases with coexistent aortic atresia and 30 cases with patent aortic root. Five hearts with aortic atresia were biventricular with atrioventricular concordance and imperforate left atrioventricular valves, and 27 hearts were u...
متن کاملTricuspid atresia with double-outlet left atrium.
Clinical and pathologic findings of an unusual case of cardiac malformation are presented. The main features were those of atresia of the right atrioventricular valve associated with two distinct atrioventricular orifices connecting the morphologically left atrium to the underlying morphologically left ventricle. Other distinguishing characteristics were ostium secundum atrial septal defect, no...
