This is a case–control study of our experience of mid-term follow-up of 40 children who had a transcatheter closure of very large atrial septal defects group (1). All cases had an atrial septal defect device size more than 1.5 times their weight, a ratio considered a contraindication for trans catheter closure (TCC) in some previous reports. The aim of this study is to report the outcomes and mid-term follow-up of transcatheter closure of large atrial septal defects using two-dimensional conventional echocardiography, tissue Doppler imaging, and four-dimensional speckle tracking imaging, and as such to compare results of same echocardiographic examination of age-matched control group of 40 healthy children group (2). Cardiac MRI was performed on cases group (1) only to detect right ventricle and left ventricle volumes and function and early signs of complications. There was no difference between cases and matched healthy controls in terms of the assessment of left ventricle and right ventricle by two-dimensional echocardiography, tissue Doppler imaging, and four-dimensional speckle tracking imaging. Similarly, there was no statistically significant difference between four-dimensional echocardiography and cardiac MRI in their respective assessment of both left ventricle and right ventricle volumes and function. We also detected no complications by echo or by cardiac MRI after a median follow-up period of 2 years and recorded a complete remodelling of right ventricle volumes in all children studied. This points to the safety and efficiency of transcatheter closure of large atrial septal defects in children on mid-term follow-up.
The Shahrizor Prehistory Project has targeted prehistoric levels of the Late Ubaid and Late Chalcolithic 4 (LC4; Late Middle Uruk) periods at Gurga Chiya (Shahrizor, Kurdistan region of northern Iraq), along with the Halaf period at the adjacent site of Tepe Marani. Excavations at the latter have produced new dietary and environmental data for the sixth millennium B.C. in the region, while at Gurga Chiya part of a burned Late Ubaid tripartite house was excavated. This has yielded a promising archaeobotanical assemblage and established a benchmark ceramic assemblage for the Shahrizor Plain, which is closely comparable to material known from Tell Madhhur in the Hamrin valley. The related series of radiocarbon dates gives significant new insights into the divergent timing of the Late Ubaid and early LC in northern and southern Mesopotamia. In the following occupation horizon, a ceramic assemblage closely aligned to the southern Middle Uruk indicates convergence of material culture with central and southern Iraq as early as the LC4 period. Combined with data for the appearance of Early Uruk elements at sites in the adjacent Qara Dagh region, this hints at long-term co-development of material culture during the fourth millennium B.C. in southeastern Iraqi Kurdistan and central and southern Iraq, potentially questioning the model of expansion or colonialism from the south.
Gurga Chiya and Tepe Marani are small, adjacent mounds located close to the town of Halabja in the southern part of the Shahrizor Plain, one of the most fertile regions of Iraqi Kurdistan. Survey and excavation at these previously unexplored sites is beginning to produce evidence for human settlement spanning the sixth to the fourth millennia, c. 5600–3300 cal. b.c. In Mesopotamian chronology this corresponds to the Late Neolithic through to Chalcolithic periods; the Halaf, Ubaid, and Uruk phases of conventional culture history. In Iraqi Kurdistan, documentation of these periods—which witnessed many important transformations in prehistoric village life—is currently very thin. Here we offer a preliminary report on the emerging results from the Shahrizor Plain, with a particular focus on the description of material culture (ceramic and lithic assemblages), in order to establish a benchmark for further research. We also provide a detailed report on botanical remains and accompanying radiocarbon dates, which allow us to place this new evidence in a wider comparative framework. A further, brief account is given of Late Bronze Age material culture from the upper layers at Gurga Chiya. We conclude with observations on the significance of the Shahrizor Plain for wider research into the later prehistory of the Middle East, and the importance of preserving and investigating its archaeological record.
Recent excavations at Tell Sitak in Iraqi Kurdistan contribute new information on the Neo-Assyrian and Sasanian occupation of this region. The site was most likely occupied between the eighth and sixth centuries b.c., in other words during the Neo-Assyrian period and perhaps for some time after. Architectural remains suggest that during this phase its primary function may have been as a fortress; smaller finds include ceramics and one Neo-Assyrian cuneiform tablet. The site was occupied again in the later Sasanian period, perhaps between the fourth and seventh centuries a.d. Remains from this period include ceramics carrying a variety of stamp seal impressions and substantial evidence for ironworking at the site.
The site of Merquly is located in a mountain pass c. 40 km north-west of Slemani (Sulaimaniyah), Iraq. Excavation at the site in 2009 revealed a fortified structure whose rooms at multiple elevations reflect a terraced structure adapted to the steep landscape contours of its setting. Both architectural preservation and quantity of finds were relatively limited; however, despite the nearby presence of a prominent Parthian period rock relief, ceramics suggest a later Sasanian date for the site. The authors discuss the 2009 season's results, and consider possible parallels for the preserved architecture, although further work is needed to securely date and characterize the site.
Recent palaeoenvironmental, historical, and archaeological investigations, primarily consisting of site reconnaissance, in the Shahrizor region within the province of Sulaymaniyah in Iraqi Kurdistan are bringing to light new information on the region's social and socio-ecological development. This paper summarises two seasons of work by researchers from German, British, Dutch, and Iraqi-Kurdish institutions working in the survey region. Palaeoenvironmental data have determined that during the Pleistocene many terraces developed which came to be occupied by a number of the larger tell sites in the Holocene. In the sedimentary record, climatic and anthropogenic patterns are noticeable, and alluviation has affected the recovery of archaeological remains through site burial in places. Historical data show the Shahrizor shifting between periods of independence, either occupied by one regional state or several smaller entities, and periods that saw the plain's incorporation within large empires, often in a border position. New archaeological investigations have provided insight into the importance of the region as a transit centre between Western Iran and northern and southern Mesopotamia, with clear material culture links recovered. Variations between periods' settlement patterns and occupations are also beginning to emerge.
