title: Self-fabricated fenestrated Amplatzer occluders for transcatheter closure of atrial septal defect in patients with left ventricular restriction: midterm results.
abstract: To avoid left ventricular failure after transcatheter closure of atrial septal defects in elderly patients with restrictive left ventricular physiology, partial occlusion by fenestrated devices may be an option. If complete defect closure is not possible in these patients, significant reduction of left to right shunting usually results in clinical benefit. We report two patients in whom deterioration of left ventricular function could be avoided by implantation of self-fabricated fenestrated Amplatzer Septal Occluders (ASO) in patients with ongoing restrictive left ventricular physiology. We describe technical preparation of the standard occluder, the specific implantation technique, and the initial and the intermediate term results up to 24 months.
