This article contents the results of computed tomography with intravenous bolus contrast media administration data analysis in children with transposition and congenitally corrected transposition of the great arteries with the consequental performing of the multiplanar heart-axis-oriented reformations. Among 148 examined children transposition of great arteries was detected in 13 patients (9 boys and 4 girls aged 1-144 day of life); congenitally corrected transposition was found in 4 cases of children aged from 6 months to 15 years and 6 months (2 boys and 2 girls). In this article comprehensive anatomical criteria of each heart chamber morphology are presented and reformations where these criteria can be seen are shown. Also in the article is given comparative characterization of heart and great arteries structures in transposition and congenitally corrected transposition in every certain heart-axis-oriented reformation. By the results of consequently performed heart-axis-oriented reformations data analysis the peculiar anatomical signs of transposition and congenitally corrected transposition are determined. The results of data analysis show that from the list of offered reformations the peculiar anatomical signs of both kinds of transposition are significantly determined in long-axis of right ventricle inflow tract reformation, left heart chambers reformation, supply ventricle division reformation, short-axis reformation at the level of great arteries. Computed tomographic angiocardiography heart-axis-oriented multiplanar reformations permit full and correct assessment of heart and main vessels, which is important for planning of surgical treatment in congenital heart diseases.

Abstract OBJECTIVES The aim of this study was to reveal the serial changes in tricuspid regurgitation (TR) after anatomic repair for congenitally corrected transposition of great arteries. METHODS Between 1995 and 2018, 48 patients underwent anatomic repair (atrial/arterial switch in 14 patients, atrial switch and Rastelli in 34 patients). The mean age and weight of the patients during anatomic repair was 33 (interquartile range 21.8–62.1) months and 12 (10.3–16.3) kg. The preoperative TR was less than mild in 15 patients (31.3%), mild-to-moderate in 29 patients (60.4%) and more-than-moderate in 4 patients (8.3%). Ebsteinoid dysplasia of the tricuspid valve (TV) was observed in 7 patients (14.6%). During the study period, no patient underwent TV surgery or bidirectional Glenn anastomosis at the time of anatomic repair. RESULTS There was 1 in-hospital death and 1 late death. The follow-up was completed by other surviving patients, with a median follow-up period of 12.1 years (5.9–18.1). The overall survival, reoperation-free survival and freedom from permanent pacemaker implantation rate at 15 years were 94.3%, 74.3% and 81.5%, respectively. The mean TR grade was 2.0 (1.0–2.6) preoperatively, 2.0 (1.0–2.0) at 1 year, 2.0 (2.0–2.0) at 5 years and 2.0 (2.0–2.0) at 10 years after anatomic repair. A Cox proportional hazards model showed that association of Ebsteinoid dysplasia of the TV, type of anatomic repair and previous pulmonary artery banding did not affect freedom from death or the more-than-moderate TR rate. There were 2 patients who underwent TV surgery after the anatomic repair for severe TR; TV repair was successfully done for 1 patient, the other required semi-closure of TV and one and one-half ventricle conversion. CONCLUSIONS TR remained subclinical or improved in the majority of patients after anatomic repair without TV repair. However, there were a few patients whose TR progressed to severe or massive, then required TV surgery after anatomic repair. Although exposure was difficult, TR was sometimes repairable following atrial switch, otherwise, one and one-half ventricle repair conversion would be the choice of treatment.

Abstract Background Patients with congenitally corrected transposition of great arteries (ccTGA) not infrequently seek medical attention for the first time late in life. Optimal management of natural history ccTGA is debated and must be tailored. Case summary A 38 years old male patient was referred to our centre because of severe cyanosis and worsening dyspnoea. Investigations disclosed: situs solitus, mesocardia, double discordance, large ventricular septal defect (VSD), severe pulmonary stenosis, no significant atrioventricular valves regurgitation. The patient underwent physiologic repair: VSD closure, placement of a left ventricle to pulmonary artery conduit and epicardial atrio-biventricular pacemaker implantation. The conduit was intentionally undersized to promote tricuspid valve continence. Postoperative course was uneventful, trans-thoracic echocardiography showed good biventricular function without significant tricuspid regurgitation. At one month after discharge the patients is in NYHA class II. Discussion Management of late presenter patients with ccTGA depends on the associated lesion and estimation of surgical risk. In selected patients markedly symptomatic physiologic repair is a rationale option, providing a normal saturation and biventricular circulation with a significantly lower surgical risk as compared with anatomic repair.
