My mother has multiple diseases like diabetes with insulin, alser, thyroid, blood pressure and also having breast cancer in past but it has been operated and radiotherapy & chemotherapy has also done. In november 2014 pacemaker has also linked up with her heart.in june 20 2016 she has two heart attacks on same day. There are 8 blockages in her heart and all 3 arteries has also blocked. So Dr. has done angiography and gave a stunt to her heart. Som please tell is there is any way to open heart blockage without by-pass surgery. Angioplasty is not possible.
