I am not very computer savvy and am not on twitter or Facebook. I am 73 an ASD was discovered during an echocardiogram. I a allergi to nickel and, since the Amplatzer device is made of nickel, I am concerned of inflammation and infection in the heat. Will it have to be removed via OHS? Because of my age I am hesitant to do anything. Has any older person (65 to 70)had the procedure done at Yale?
