Authors: Grech, Victor E.; Felice, Herbert; Fenech, Albert; DeGiovanni, Joseph V.
Abstract: Transcatheter closure of atrial septal defects and patent foramen ovale is now a well
established therapeutic option. In this paper, we illustrate, step by step, the technique
of Amplatzer ASO closure of these defects.2003-01-01T00:00:00ZBalloon expandable stents for coarctation of the aorta : review of current status and technical considerationsEbeid, Makram R.https://www.um.edu.mt/library/oar/handle/123456789/39432019-01-12T08:50:10Z2003-01-01T00:00:00ZTitle: Balloon expandable stents for coarctation of the aorta : review of current status and technical considerations
Authors: Ebeid, Makram R.
Abstract: Balloon expandable stents have been used to manage coarctation of the aorta in
selected patients with very encouraging results. After the successful use of the
Palmaz stents in these lesions newer stents as well as modifications of the Palmaz
stents have been introduced to achieve optimal results in these patients. In this
review, the older as well as the newer type stents used in coarctation are discussed.
Technical considerations to achieve successful stent implantation and choice is
outlined.2003-01-01T00:00:00ZDefining the morphologic phenotypes of atrial septal defects and interatrial communicationshttps://www.um.edu.mt/library/oar/handle/123456789/39422017-12-06T13:43:10Z2003-01-01T00:00:00ZTitle: Defining the morphologic phenotypes of atrial septal defects and interatrial communications
Abstract: True atrial septal defects are limited to deficiencies totally within the confines
of the oval fossa and its antero-inferior rim. Other communications between
the two atriums, such as the superior or inferior sinus venosus defects,
coronary sinus defect, and the ostium primum defect, are less frequently
seen. They represent interatrial communications rather than septal defects,
since the communication between the atrial chambers is outside the confines
of the true atrial septum. The ostium primum defect, for example, has all the
characteristics of an atrioventricular septal defect, existing only in the setting
of a common atrioventricular junction. The unifying physiological feature of all
these variants, whether their morphology is that of a defect within the area of
the oval fossa, or an opening elsewhere within the atrium, is that mixing of the
systemic and pulmonary blood occurs at atrial level. In this review, we
emphasise the distinction between true atrial septal defects and defects which
result in communications between the atriums, underlining the phenotypic
characteristics, along with the notable morphological features that are of
significance in current strategies for clinical management.2003-01-01T00:00:00Z
