Brain Hemorrhage. Of him being okay?

My Grandfather had a Cardiac arrest 4 days ago, there was this Blood Clot formed in his Heart n da Clot was to be removed.After the discussion with the Cardiologist in-charge, he gave me 2 options to overcome this situation, to perform Angioplasty and remove the clot from his heart surgically OR give him an Injection (Some high power anti-coagulant) n remove the clot without surgery. I did consult the Cardiologist about the outcomes of the both options. I went ahead N told him to go with the injection. So da Injection was given. After 1 hour the clot from his heart was stable and nullified. But after 14 hours of the Injection he encountered Brain bleeding. (The Cardiologist did tell me that there's 1% chance of brain bleeding because of that Injection). Now I shifted him to other hospital and this surgery was performed where this tube was taken out from brain m excess fluid was removed. Hes on ventilator.TELL ME IF ANGIOPLASTY WAS THE BEST OPTION N What r da chances of him being okay?
