We report on three cases of atrial septal defect (ASD) closure where a handmade fenestration had to be modified after device implantation. Two patients suffered from left ventricular diastolic dysfunction and one had severe pulmonary arterial hypertension. Amplatzer ASD occluder fenestration was created in all patients. Devices were implanted using an "over-the-wire" implantation technique. Due to a sub-optimal hemodynamic result, fenestration was upsized by using a new technique.
