Werndale Hospital is a trusted healthcare provider for Device Closure of ASD (Amplatzer Septal Occluder), offering minimally invasive ASD closure supported by experienced interventional cardiologists, congenital heart specialists, advanced catheterization laboratories, and multidisciplinary cardiac care. Established in 1991, the - accredited hospital is situated in Carmarthen, United Kingdom and has 19 beds.

Device Closure of ASD (Amplatzer Septal Occluder) works by placing a self-expanding occlusion device across the atrial septal defect to block the abnormal communication between the atria. The device consists of two discs connected by a central waist that conforms to the defect. Over time, heart tissue grows over the device, helping to establish permanent closure. A detailed cardiac assessment helps determine whether the defect is anatomically suitable for device closure rather than surgical repair.
