A 58-year-old woman in Central Africa has been diagnosed with an intermediate Atrioventricular Septal Defect (AVSD) coupled with severe Pulmonary Arterial Hypertension (PAH), a rare combination presenting diagnostic and therapeutic challenges in resource-limited settings, according to a case study published by SCIRP Open Access.
The patient, whose specific country of origin within Central Africa was not detailed in the report, presented with progressive dyspnea and fatigue. Initial investigations revealed significant cardiac abnormalities, ultimately leading to the diagnosis of an intermediate AVSD – a congenital heart defect involving incomplete closure of the atrial and ventricular septa – alongside severe PAH, a condition characterized by high blood pressure in the arteries of the lungs.
Diagnosing congenital heart disease in regions like Sub-Saharan Africa presents unique obstacles. Access to advanced imaging techniques, such as cardiac Magnetic Resonance Imaging (MRI), is often limited. However, recent advancements in applying artificial intelligence to cardiac MRI are showing promise in improving diagnostic capabilities in these low-resource environments, as reported by Communications Medicine in Nature. The case study does not specify whether AI-assisted MRI was utilized in this particular diagnosis.
The patient’s case was further complicated by the late diagnosis. Typically, AVSDs are identified and addressed in infancy or early childhood. Delayed presentation, as seen in this instance, often results in the development of secondary complications like PAH, which significantly increases the risk associated with any potential intervention. The management of PAH in conjunction with cardiac surgery is particularly complex, even in well-equipped medical centers, and is further compounded in resource-limited settings, as highlighted in a SCIRP Open Access report on perioperative management of pulmonary hypertension.
The report details the challenges faced in managing the patient’s condition, including limited access to specialized medications and surgical expertise. While specific treatment details were not provided, the case underscores the need for improved diagnostic and therapeutic infrastructure for congenital heart disease in Central Africa. The case study also notes the importance of considering rare syndromes that can present with similar cardiac manifestations. A separate report published by Wiley Online Library details a case of Lutembacher syndrome, a rare condition involving an atrial septal defect and mitral stenosis, diagnosed in a middle-aged woman in Ghana, demonstrating the continued need for vigilance in identifying atypical cardiac presentations in the region.
The patient’s long-term prognosis remains uncertain, and further follow-up is required to assess the effectiveness of any implemented treatment strategies. The case highlights the critical need for increased awareness, early detection, and improved access to care for individuals with congenital heart disease in Central Africa.
