    Complete transposition of great arteries (TGA) is a common and nearly fatal cyanotic congenital cardiac malformation if not treated in time. Without any intervention, nearly 50% succumb in neonatal period and 90% before their first birthday. Advancements in diagnostic and surgical modalities have led to significant improvement in the survival rate of these children. This article discusses comprehensive echocardiographic evaluation in TGA and its variants before and after surgical correction.

    SUMMARY The pre-ejection period of the right ventricle in d-transposition of the great arteries is known to be prolonged, compared with the same interval of the left ventricle of normal subjects. In the present study, the echocardiographic measurement of the components of the pre-ejectionperiod ofthe right ventricle of 14 patients with d-transposition ofthe great arteries shows that theisometric contraction time ofthe right ventricle in d-transposition ofthe great arteries is similar to the same interval calculated on the left ventricle of 76 normal children of comparable age. On theotherhand,theelectromechanicaldelay was significantly greater fortherightventricleofd-transpositionofthe great arteries than for the left ventricle ofthe normal subjects. It is concluded that the pro- longed pre-ejection period ofthe right ventricle in d-transposition of the great arteries is not the result ofright ventricular dysfunction but solely of a longer electromechanical delay. In d-transposition of the great arteries (d-TGA),the

    Abstract This study presents and explains the phenomenon of indexjacking , which involves the systematic infiltration of hijacked journals into international indexing databases, with Scopus being one of the most infiltrated among these databases. Through an analysis of known lists of hijacked journals, the study identified at least 67 hijacked journals that have penetrated Scopus since 2013. Of these, 33 journals indexed unauthorized content in Scopus and 23 compromised the homepage link in the journal's profile, while 11 did both. As of September 2023, 41 hijacked journals are still compromising the data of legitimate journals in Scopus. The presence of hijacked journals in Scopus is a challenge for scientific integrity due to the legitimization of unreliable papers that have not undergone peer review and compromises the quality of the Scopus database. The presence of hijacked journals in Scopus has far‐reaching effects. Papers published in these journals may be cited, and unauthorized content from these journals in Scopus is thus imported into other databases, including ORCID and the WHO COVID‐19 Research Database. This poses a particular challenge for research evaluation in those countries, where cloned versions of approved journals may be used to acquire publications and verifying their authenticity can be difficult.

    Objective To review and summarize primary arterial switch operation used in complete transposition of great arteries(D-TGA).Methods Ten patients with complete transposition of great arteries were repaired by primary arterial switch operation during April 2004 to March 2009.There were 5 patients with transposition of great arteries and intact ventricular septum(D-TGA/IVS),and 5 patients with transposition of great arteries and ventricular septal defect(D-TGA/VSD).The operative age was(39±21.8)days,and weight(3.65±1.24)kg.Results There were 2 deaths.8 patients were followed-up 3 months to 4 years.There was one mild pulmonary obstruction.The echocardiography of all patients showed good heart function.Conclusion The primary arterial switch operation used in complete transposition of great arteries had a satisfactory results.The successful operation is the key that switch operation should be performed as early as possible and implantation of the coronary had to be patent.
