If the angiogram is not with a cath (invasive), what is going to be the
procedure if the non-invasive test is positive?...it would require an invasive
procedure. But if your mother's symptoms can be successfully treated with medication, there may not be a need for any procedure. I have blockages of coronary vessels (LAD completely blocked and another 72% blocked), I have been successfully treated for the past 6 years and no chest pain, etc.
