Atrial Septal Defect (ASD) Device Closure: Case Summary

Dr Arulanandhan Ettiyan, Dr. Sureshkumar Ponnuswamy

Abstract: This case presents a compelling example of how advanced percutaneous techniques can be safely and effectively employed to manage large atrial septal defects in adult patients. A 26-year-old female with a diagnosed secundum ASD, measuring 26 mm and associated with mild pulmonary hypertension, reported with chest discomfort over several weeks. Despite having dilated right heart chambers, her hemodynamic parameters remained stable throughout evaluation and treatment. What stands out is the meticulous approach to diagnosis utilizing TTE, TEE, and fluoroscopy to guide the transcatheter device closure. The strategic choice of a 28 mm occluder, confirmed through imaging and pressure readings, reflects a high degree of procedural precision. It is evident that the multidisciplinary coordination and careful pre-procedural planning played a pivotal role in achieving an optimal outcome. This suggests that even sizable ASDs with rim limitations can be closed safely using percutaneous methods when performed in a structured, image-guided environment. From a broader clinical perspective, the success of this intervention reinforces the expanding boundaries of minimally invasive cardiology and underscores the importance of individualized patient assessment.
