Grandmas rally for heart surgery

Hello everyone. I am raising Money for my lovely grandmother. She is 81. Will turn 82 Aug 02. She has survived colon Cancer and She has A Heart condition that has progressed to Afib which stands for atrial fibrillation. AFib is a quivering or irregular heartbeat (arrhythmia) that can lead to blood clots, stroke, heart failure and other heart-related complications. She must have an Ablation/ Angioplasty. Soon which will correct this problem. She is constantly nauseated, having difficulty breathing, can not complete her activities of daily living, and can't go on her walks anymore because of this.
She is busy trying to take care of a son who is really sick which is causing her even more stress on her heart. She will need to travel to Atlanta GA and be treated at Emory Healthcare. H Medicaid and Medicare have not kicked in for her and not sure how long it will be before it does. Her medications are costly and she can hardly maintain. The estimated cost for the hospital, MD , surgery and post op care is roughly $25,000. ANY amount you can donate would be GREATLY appreciated. Thank you all so much for your kindness and willingness to help out my Grandma.
