Closure of a moderately large atrial septal defect with a self-fabricated fenestrated Amplatzer septal occluder in an 85-year-old patient with reduced diastolic elasticity of the left ventricle.
Overview
abstract
Percutaneous closure of an atrial septal defect (ASD) in the elderly with reduced diastolic elasticity of the left ventricle poses a significant management challenge. We report on the case of an 85-year-old patient who was admitted for percutaneous device closure of a moderately large secundum atrial septal defect. Hemodynamic evaluation documented an increase in left atrial pressure from a mean of 12 mm Hg to a mean of 32 mm Hg after balloon test occlusion of the ASD. Two months later, after adequate pretreatment with diuretics and afterload-reducing substances, he underwent successful closure of the ASD using a self-fabricated fenestrated Amplatzer septal occluder, which resulted in a postimplantation left atrial pressure of a mean of 18 mm Hg. Recovery was unremarkable and the fenestration has remained patent for 3 months since implantation of the device. This unique case highlights the feasibility of using a self-fabricated fenestrated Amplatzer septal occluder to close interatrial communications in elderly patients with diastolic dysfunction of the left ventricle.
