RESUMEN
Objective: The atrio-ventricular and ventricle-arterial double discordance (DD) or corrected transposition of the great arteries is a rare heart disease, it occurs in 0.02-0.07 of every 1,000 live newborns. The objective of the study is to describe the diagnosis, treatment and evolution of a series of patients with DD. Method: A retrospective and descriptive study was carried out, reviewing the records of patients diagnosed with DD in the last 22 years. Descriptive statistics were performed. Numerical variables were obtained using means and standard deviation and categorical variables using frequencies and percentages. Results: Thirty patients were studied in 22 years with a ratio of 1.5:1 for men, with a mean age of 20 months. The situs was solitus in 24/29 patients (82.7%). Ventricular septal defect was the most frequent lesion in 25/29 (86.2%) Tricuspid insufficiency in 70%. Four patients diagnosed with pulmonary atrial hypertension. With atrio-ventricular block 20%. One with Wolff-Parkinson-White syndrome. Surgical treatment was carried out in 70% of patients. Eight with Glenn procedure (26.6%) and 4 with Fontan surgery (13.3%). Follow-up ranged from 1 month to 17 years. Five died (16.6%). Of the 25 patients in follow-up, 18 patients (72%) had normal ventricular function, 5 with Grade II Ross classification (20%) and 2 in Grade III (8%). Conclusions: The quality of life of these patients is improving and there is still controversy in the literature about the ideal time to perform the most appropriate surgical procedure.
Objetivo: La doble discordancia auriculo-ventricular y ventrículo-arterial (DD) o transposición corregida de las grandes arterias, se presenta en 0.02-0.07 de cada 1,000 recién nacidos vivos. El objetivo del estudio es describir el diagnóstico, tratamiento y evolución de pacientes con DD. Método: Se realizó un estudio retrospectivo y descriptivo, revisando los registros de pacientes con DD en los últimos 22 años. Se realizó estadística descriptiva. Las variables numéricas se obtuvieron mediante medias y desviación estándar y las categóricas mediante frecuencias y porcentajes. Resultados: Se estudiaron 30 pacientes con una relación de 1.5:1 para el varón, con una edad media de 20 meses. El situs fue solitus en 24/29 pacientes (82.7%). La comunicación interventricular fue la lesión más frecuente en 25/29 pacientes (86.2%), insuficiencia tricuspídea en el 70%. Cuatro pacientes con diagnóstico de hipertensión arterial pulmonar. Con bloqueo atrio-ventricular un 20%. Uno con síndrome de Wolff-Parkinson-White. El tratamiento quirúrgico se realizó en el 70% de los pacientes. Con procedimiento de Glenn 8 (26.6%) y 4 cirugías de Fontan (13.3%). El seguimiento fue de 1 mes a 17 años. Cinco fallecieron (16.6%). De los 25 restantes, 18 pacientes (72%) con función ventricular normal, 5 con clasificación de Ross grado II (20%) y 2 en G III (8%). Conclusiones: La calidad de vida de estos pacientes está mejorando, aún existe controversia sobre el momento ideal para realizar el procedimiento más adecuado quirúrgico.
RESUMEN
Congenitally corrected transposition of the great arteries is a rare clinical entity, which usually presents during adulthood with associated defects; atrioventricular block, heart failure, systemic valve failure, and arrhythmias usually complicate the clinical course. Even rarer is associated hypertrophic cardiomyopathy, which complicates the disease course and clinical decision-making. Herein, we present a patient with this condition who underwent heart transplantation, with adequate clinical resolution.

ABSTRACT Introduction: Congenitally corrected transposition of the great arteries (CCTGA) is a rare anomaly. Current data available regarding adult cases is derived from small series, information simultaneously presented in pediatric publications, and one classical multicenter study. This review, not aimed to exhaust the subject, has the purpose to examine the literature addressing presentation, diagnostic methodology, and management of afflicted adult patients. Methods: A comprehensive search was undertaken in three major databases (PubMed, Cochrane, SciELO), using the keywords "congenitally corrected transposition of the great arteries" and "adults". Relevant articles in English, Spanish, and Portuguese were extracted and critically appraised in this review. Steps for study selection were: (1) identification of titles of records through databases searching, (2) removal of duplicates, (3) screening and selection of abstracts, (4) final inclusion in the study. Results: Four hundred sixty-five publications on CCTGA in adult patients were retrieved, and 166 were excluded; 299 studies were used for this review including 76 full-text articles, 70 studies related to general aspects of the subject, and, due to the small number of publications, 153 case reports. Sixty-one articles referring to combined experiences in pediatric and adult patients and judged to be relevant, but retrieved from another sources, were also included. Conclusion: Albeit clinical presentation and diagnostic criteria have been well stablished, there seems to be room for discussion related to clinical and surgical management of CCTGA in adults. Considering the rarity of the disease, well designed multicenter studies may provide answers.

BACKGROUND: Congenitally corrected transposition of the great arteries is a complex pathology characterised by atrioventricular and ventriculo-arterial discordance. Optimal surgical approaches are still a matter of debate. OBJECTIVE: To evaluate the outcomes of different surgical treatments in a single centre. METHODS: Between 1998 and 2020, 89 patients were studied. The cohort was divided into three groups: physiologic, anatomic, and univentricular repair. RESULT: Physiologic correction (56.18%) was associated with significant tricuspid valve regurgitation progress (42%) and complete AV block (30%) compared to anatomic repair. Right ventricular systolic dysfunction was developed in 14%. Instead, anatomic correction (30.34%) (double switch 59% and Rastelli type 40.7%) presented moderate to severe aortic regurgitation (4%) and left ventricular systolic dysfunction (11%). Complete AV block was developed in 14.8%. Rate of reintervention was 34% for physiologic and 26% for anatomic. Univentricular palliation (13.8%) presented no complications or late mortality during the follow-up. The overall survival at 5 and 10 years, respectively, was 80% (95% CI 69, 87) and 75% (95% CI 62, 84). There was no statistically significant difference in mortality between the groups (p log-rank = 0.5752). CONCLUSION: Management of congenitally corrected transposition of the great arteries remains a challenge. In this cohort, outcomes after physiologic repair were satisfactory in spite of the progression of tricuspid regurgitation and the high incidence of AV block. Anatomic repair improved tricuspid regurgitation but increased the risk of aortic regurgitation and left ventricular systolic dysfunction. The Fontan group showed the lowest incidence of complications.
RESUMEN
In this article, we report the third case, to our knowledge, of a congenitally corrected transposition of the great arteries associated with an interrupted aortic arch. This is a more complex and rare presentation than dextro-transposition of great arteries with interrupted aortic arch. The child ultimately succumbed to sepsis before the surgical repair was possible. We focus on an image modality report and propose what could be a brief embryologic explanation for this rare case.
RESUMEN
We report a man with congenitally corrected transposition of the great arteries and moderate anteroseptal ischemia; and cardiac computed tomography showed a single coronary artery with origin from the right aortic sinus. The perfusion of the morphological right ventricle by a single right coronary artery may be a cause of ischemia. (Level of Difficulty: Beginner.).
RESUMEN
Congenitally corrected transposition of the great arteries is a rare and complex congenital heart disease. It essentially occurs with atrioventricular and ventriculoarterial discordance, in which the great vessels become parallel. Cases of corrected transposition of the great arteries are more frequently associated with other cardiac anomalies. In the fetus, corrected transposition of the great arteries may not be diagnosed on obstetric cardiac ultrasound, especially in the absence of other cardiac malformations (isolated corrected transposition of the great arteries). In this manuscript, we describe a case of isolated corrected transposition of the great arteries diagnosed in utero, and highlight the clues to make this diagnosis.
