Embryological misalignment between the aorta and pulmonary trunk gives rise to the congenital anomaly of the heart known as transposition of the great arteries (TGA). TGA is a type of parallel circulation, where the heart pumps oxygenated blood from the left ventricle into the pulmonary trunk. The deoxygenated blood from the right ventricle is circulated into the body as it pumps blood into the aorta. This type of parallel circulation is not compatible with life unless there is communication between oxygenated and deoxygenated blood...

We present a case of anatomic repair of dextro-transposition of the great arteries (d-TGA) with ventricular septal defect (VSD) in a 55-year-old man who presented with acute heart failure. This case highlights the importance of multimodal imaging and multidisciplinary involvement in developing a comprehensive surgical and medical plan for adults with congenital heart disease. We think this is the oldest reported patient undergoing anatomic surgical repair of d-TGA with VSD.

OBJECTIVES: Predicting whether balloon atrial septostomy (BAS) will be necessary after birth for fetuses with d-transposition of the great arteries (d-TGA) remains challenging. We sought to determine whether measurements obtained during fetal maternal hyperoxygenation (MH) testing can improve our ability to predict need for postnatal BAS. METHODS: Forty-one mothers carrying fetuses with d-TGA with either intact ventricular septum or small ventricular septal defect measuring <3mm underwent MH testing between 33-38 weeks gestation...

OBJECTIVES: This study aimed to evaluate the short-/mid-term outcome of patients with complex dextro-/levo-transposition of the great arteries (d-/l-TGA), ventricular septal defect (VSD) and left ventricular outflow tract obstructions (LVOTO). METHODS: A single-center, retrospective review of all complex d-TGA (n = 85) and I-TGA (n = 22) patients undergoing different surgeries (Arterial switch operation (ASO)+LVOTO-resection (ASO-R), half-turned truncal switch/Mair (HTTS), Nikaidoh and Rastelli) between 05/1990-09/2022 was performed...

• Echo is an essential tool for monitoring long-term complications of D-TGA with ASO. • Multimodality imaging is complementary to echo in the assessment of complications. • 4D flow CMR can assess supravalvular PS post ASO. • Branch pulmonary arteries after LeCompte maneuver can be challenging to image.

OBJECTIVE: This study aimed to assess the diagnostic value of prenatal echocardiography for identifying transposition of the great arteries (TGA) during pregnancy and evaluating the associated outcomes. METHODS: We conducted a retrospective analysis of 121 prenatally diagnosed patients with TGA at our hospital between January 2012 and September 2022. This analysis included prenatal ultrasound, prenatal screening, clinical management and follow-up procedures. RESULTS: Among the 103 fetuses considered in the study, 90 (87...

BACKGROUND: Distances between delivery and cardiac services can make the care of fetuses with cardiac disease at risk of acute cardiorespiratory instability at birth a challenge. In 2013 we implemented a fetal echocardiography-based algorithm targeting fetuses considered high risk for acute cardiorespiratory instability at ≤2 hours of birth for delivery in our pediatric cardiac operating room of our children's hospital, and, herein, examine our experience. METHODS AND RESULTS: We reviewed maternal and postnatal medical records of all fetuses with cardiac disease encountered January 2013 to March 2022 considered high risk for acute cardiorespiratory instability...

BACKGROUND: Transthoracic Echocardiography is the first-line, non-invasive, and accessible imaging modality to evaluate heart disease anatomy, physiology, and hemodynamics. We aim to describe the trans-thoracic echocardiography pattern of pediatric heart diseases and reasons for referral in children referred to Bahir Dar University Tibebe-Ghion Hospital and Adinas General Hospital. METHOD: A descriptive cross-sectional study of the archived Transthoracic, Two Dimensional, and Doppler Echocardiography assessments of children from birth to fifteen years of age performed between June 2019 to May 2023 was done...

We present a case of a patient known for dextrotransposition of the great arteries corrected with a Mustard procedure, in whom severe mitral valve regurgitation secondary to transvenous lead extraction was successfully repaired with transcatheter edge-to-edge repair using the TriClip device (Abbott Vascular).

BACKGROUND: No study has focused on left atrial (LA) function assessed by echocardiography in adult patients with simple D-TGA after arterial switch operation (ASO). We aimed to describe LA strain parameters in these patients. METHODS: A prospective cohort study including 42 adult patients with simple D-TGA after ASO and 33 aged-matched controls. Phasic LA and LV global longitudinal strain (GLS) were obtained by transthoracic 2D-speckle tracking echocardiography (STE)...

Despite their anatomical differences, congenitally corrected (ccTGA) and complete transposition of the great arteries (d-TGA) post-atrial switch are frequently studied together and managed similarly from a medical standpoint due to the shared systemic right ventricle (sRV). The aim was to assess differences in their underlying hemodynamics. The study is a retrospective review of 138 adults with ccTGA or d-TGA post-atrial switch undergoing cardiac catheterization at Mayo Clinic, MN between 2000 and 2021...

Persistent pneumothorax is a life-threatening complication that can occur after congenital cardiac surgery. Traditional treatment such as chest tube drainage may not be effective in managing this condition. This study presents a new minimally invasive method for treating persistent pneumothorax using platelet-rich plasma-fibrin glue (PRP-FG). The method has been successful in treating postoperative chylothorax in previous studies, and its use has decreased morbidity, mortality, and hospital stay in chylothorax patients...

BACKGROUND: Neo-aortic root dilatation can lead to significant late morbidity after the arterial switch operation (ASO) for dextro-transposition of the great arteries (d-TGA). OBJECTIVES: We sought to examine the growth of the neo-aortic root in d-TGA. METHODS: A single-center, retrospective cohort study of patients who underwent the ASO between July 1, 1981 and September 30, 2022 was performed. Morphology was categorized as dextro-transposition of the great arteries with intact ventricular septum (d-TGA-IVS), dextro-transposition of the great arteries with ventricular septal defect (d-TGA-VSD), and double-outlet right ventricle-transposition of the great arteries type (DORV-TGA)...

BACKGROUND: Pulmonary hypertension (PH) is a common complication in patients with complete dextro-transposition of the great arteries (TGA) after atrial switch (D-TGA/AS) and congenitally corrected TGA (ccTGA). In this population with subaortic right ventricles (sRVs), echocardiography is a poor screening tool for PH; implantable invasive haemodynamic monitoring (IHM) could be used for this purpose, but data are limited. The aim of this study is to report on novel uses of IHM in patients with sRV...

BACKGROUND: D-Transposition of the great arteries (d-TGA) is characterized by the aorta positioned above the right ventricle and the pulmonary artery above the left ventricle. Acute pulmonary artery dissection (PAD) is a rare and often lethal condition. We present a case report of acute PAD in an adult with d-TGA and pulmonary hypertension. CASE SUMMARY: A 49-year-old male with history of d-TGA palliated with an atrial switch (Mustard) operation, pulmonary venous baffle stenosis treated percutaneously, chronic pulmonary hypertension (mixed group 1 and 2), and severe dilatation of pulmonary arteries (pulmonary trunk of 75 mm) presented to the emergency department with chest pain and acute respiratory failure...

BACKGROUND: Patients with dextrocardia and d-transposition of the great arteries (d-TGA) present a technical challenge when performing the arterial switch operation (ASO). We sought to determine the long-term outcomes of this rare presentation. METHODS: All patients who underwent the ASO with d-TGA and dextrocardia were identified from the hospital database. RESULTS: There were four patients with dextrocardia (4 of 844, 0.5%) patients; two patients had situs solitus and two patients had situs inversus...

The arterial switch operation (ASO) has become the standard surgical treatment for patients with d-transposition of the great arteries (d-TGA). While ASO has significantly improved survival rates, a subset of patients develops a unique anatomical anomaly known as the gothic aortic arch (GAA). Understanding cardiac mechanics in this population is crucial as altered mechanics can have profound consequences on cardiac function and exercise capacity. The GAA has been associated with changes in ventricular function, hemodynamic, and exercise capacity...

BACKGROUND: Adult congenital heart disease (ACHD) patients pose unique challenges in identifying the time for transplantation and factors influencing outcomes. OBJECTIVE: To identify hemodynamic, functional, and laboratory parameters that correlate with 1- and 10-year outcomes in ACHD patients considered for transplantation. METHODS: A retrospective chart review of long-term outcomes in adult patients with congenital heart disease (CHD) evaluated for heart or heart + additional organ transplant between 2004 and 2014 at our center was performed...

Patients with dextro transposition of the great arteries (d-TGA) after atrial switch procedure are at risk to develop heart failure and arrhythmias during long-term follow-up. The present study aims to add knowledge on the fate of subjects after Mustard procedure during long-term follow-up into adulthood. A single center, retrospective chart review analysis was conducted. All subjects who had Mustard-type atrial switch procedure between 1969 and 1994 at our institution were included. A total of 92 subjects were included...

The population of patients with a systemic right ventricle (sRV) in biventricular circulation includes those who have undergone an atrial switch operation for destro-transposition of the great arteries (d-TGA) and those with congenitally corrected transposition of the great arteries (ccTGA). Despite the life expectancy of these patients is significantly increased, the long-term prognosis remains suboptimal due to late complications such as heart failure, arrhythmias, and premature death. These patients, therefore, need a close follow-up to early identify predictive factors of adverse outcomes and to implement all preventive therapeutic strategies...
