my father has had angiography today – 80%-90% blockage – another angiography? or bypass surgery.
hi. blocks less than 50 % can be treated by angioplasty. i. e removal of blockage by balloon inflation inside the vessel this is a closed heart surgery. by pass is a open heart surgery and if the blockages are more than 70 % the by pas is the best treatment availble. u can perform angiography after 2 days but it will be of no use. the results and treatment options will be the same thanks
