Hope he is doing well now and recovers quickly. I know what your family is going through, it sounds exactly what we went through with my husband. 8 Am was his heart cath, found he had a 99% blockage in a main artery so by 1pm he was in for emergency bypass, then two days later he was opened back up for bleeding, had an extra chest tube put in and an extra few days stay but was home within the week. He later had to have fluid removed from around his lungs but that was an in office procedure. Scariest thing I've ever been through but now he is better than ever and back to doing everything he was before.
