The adductor fossa is considerably wider (20 mm) than in equivalent-sized mastodonsaurid mandibles, and measures 115 mm in length.
Detailed anatomical examination of the oval fossa and its environs relative to placement of the device is obviously of great practical importance.
The adductor fossa and the anterior and posterior meckelian foramina are also partially filled with matrix.
Morphological variations of fossa ovalis atrial septal defects (secundum): feasibility for transcutaneous closure with the clam-shell device.
The echocardiogram demonstrated an atrial septal defect within the oval fossa and normal contractility.
Only one patient had a sinus venosus defect in addition to the defect within the oval fossa.
Note the location and relationships of the oval fossa.
When considering the technical aspects of percutaneous closure of defects within the oval fossa, we should not forget the natural history of this malformation.
