Yet, when it comes to sinus venosus atrial septal defects (ASDs), the intricate anatomical challenges have largely limited the adoption of minimally invasive surgical solutions in these cases. Reports of minimally invasive repair for this particular defect have been sparse, and most such cases involve adult patients. In this account, we detail the management of a 12-year-old child who successfully underwent correction of the defect via a right mini-thoracotomy. This technique eliminates the need for direct cannulation of the central aorta and inferior vena cava, thus maintaining a clear operative field. Repair through right minithoracotomy and femoral cannulation is a viable option for pediatric patients weighing at least 20 kg, providing an effective alternative to the traditional midsternotomy. Superior vena cava (SVC) drainage preinsertion of partial anomalous pulmonary venous connection (PAPVC) was done through direct cannulation of the SVC. Notably, the distinct bay formed within the right atrium over a superiorly located defect enhances exposure to the SVC, pulmonary veins, and ASD, facilitating precise surgical intervention.  \nCategories: Cardiac/Thoracic/Vascular Surgery  \nKeywords: minimally invasive cardiac surgery, minithoracotomy, papvc, sinus venosus atrial septal defect, svc  \nIntroduction  \nThe surgical correction of atrial septal defects (ASDs) holds historical significance, marking the dawn of open-heart surgery after John Gibbon successfully performed the first ASD closure under cardiopulmonary bypass (CPB) in 1953. Since that landmark procedure, ASD repair has achieved outstanding outcomes, with minimal operative mortality, very low complication rates, and excellent long-term prognosis [1] . In recent years, there has been a notable shift toward minimally invasive cardiac surgery (MICS) techniques for ASD closure, motivated by their cosmetic advantages, reduced blood loss, shorter hospitalizations, and quicker patient recovery. Percutaneous device closure has also gained widespread acceptance, as it is the least invasive option and can even eliminate the need for CPB [2] . Transcatheter/percutaneous closure of sinus venosus ASD (SV-ASD) is also possible [3] .  \nSV-ASDs arise due to the unroofing of the right pulmonary veins, which results in these veins draining anomalously into the superior vena cava (SVC) or directly into the right atrium (RA) [4] . SV-ASDs account for roughly 5%-10% of all ASD types. Diagnosis of SV-ASD on transthoracic echocardiography (TTE) is particularly challenging. It often necessitates the complementary use of more advanced studies, specifically transesophageal echocardiography (TEE), cardiac magnetic resonance imaging (CMR), cardiac computed tomography (CT), and, rarely, cardiac catheterization [5] .  \nOwing to their intricate anatomy-often requiring complex surgical baffling or advanced devices to redirect flow from the SVC to the RA and from the right pulm","cbCaihamu7tWAgkU","https://ap.wps.com/l/cbCaihamu7tWAgkU","pdf",1422883,"English","# Abstract\n# Introduction\n# Case Presentation","[{\"question\":\"Why are minimally invasive repairs less common for sinus venosus atrial septal defects?\",\"answer\":\"The defect’s intricate anatomy often requires complex surgical reconstruction or advanced techniques to redirect flow, which has historically limited minimally invasive adoption.\"},{\"question\":\"What surgical approach was used in the reported pediatric case?\",\"answer\":\"The child underwent correction via a right mini-thoracotomy with femoral cannulation.\"},{\"question\":\"How was the defect exposure enhanced during surgery?\",\"answer\":\"Superior positioning of the defect created a distinct bay within the right atrium, improving exposure to the SVC, pulmonary veins, and the ASD for precise intervention.\"}]","Minimally Invasive Approach for Superior Sinus Venosus Atrial Septal Defect Repair in a Child - A Case Report | PDF",1790762205,13]
