Right atrial isomerism (RAI) is a complex entity with varying diagnostic and treatment outcomes due to its rarity. Treatment options range from palliative to corrective surgeries, resulting in heterogeneous outcomes. The aim of this study was to analyze the results obtained after cardiac surgery in patients with RAI. A retrospective study was conducted, including patients diagnosed with RAI who underwent cardiac surgery. Their follow-up was from 1 January 2010 to 31 March 2020. Demographic characteristics and perioperative conditions were described. Thirty-eight patients were included, the median age was 4 years (IQR 2-9.2) and 57.9% were men. The main diagnoses were atrioventricular canal (63.2%) and pulmonary stenosis (55.3%). The most common surgical procedures were modified Blalock-Taussig shunt (65.8%) and total cavopulmonary connection with an extracardiac conduit fenestrated without cardiopulmonary bypass (15.9%). We did not find any factors associated with negative outcomes in these patients. The overall survival was 86.8%, with a better outcome in those who did not require reintubation (log rank, < 0.01). The survival of RAI was similar to other centers. Individuals with RAI should be evaluated rigorously to determine an adequate repair strategy, considering high morbidity and mortality.

Department of Cardiovascular Radiology & Endovascular Interventions, All India Institute of Medical Sciences, New Delhi, 110029, India.
We sought to evaluate the intracardiac morphology and associated cardiovascular anomalies in patients with double inlet right ventricle (DIRV) on multidetector CT angiography. A retrospective search of our departmental database was conducted from January 2014 to January 2023 to identify patients with a diagnosis of DIRV on CT angiography. The intracardiac anatomy and associated cardiovascular abnormalities were systematically evaluated.

Coarctation of the aorta (CoA) accounts for a small percentage of all congenital heart diseases (CHD) and occurs with a rare incidence in live births. It is a frequently diagnosed cardiac defect in infancy, though some patients present later with severe complications and reduced life expectancy. Heterotaxy syndrome is marked by abnormal lateralization of abdominal and thoracic organs, including the cardiac atria.

Article Synopsis
- The study focused on understanding the patterns of tachycardia related to single or multiple atrioventricular (AV) nodes in patients with right atrial isomerism (RAI) and evaluated the effectiveness of ablation therapy.
- Researchers analyzed medical records of 16 RAI patients who underwent catheters ablation for tachycardias between 2006 and 2020, finding various tachycardia patterns and successful treatment outcomes.
- The results showed that ablation successfully eliminated tachycardias in 93.8% of patients, although 44% experienced recurrence over a median follow-up of about 8 years, with minimal impact on cardiac function post-procedure.

Division of Pediatric Cardiology, Department of Pediatrics, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand.
Objective: This study compared the accuracy of prenatal congenital heart disease (CHD) diagnosed by maternal-fetal medicine specialists (MFMs) and pediatric cardiologists (PCs), using postnatal cardiac findings as the reference standard.
Methods: This retrospective analysis at Siriraj Hospital, Bangkok, Thailand, involved 125 pregnancies with fetal CHD diagnosed by MFMs and evaluated by PCs later. Prenatal CHD diagnoses by either MFM or PC were compared with postnatal diagnoses obtained through echocardiography, cardiac surgery/catheterization, or autopsy.
