Eleven weeks later:
Sam had a cardiologist appointment today. They did an echocardiogram and said his heart was in great shape. They felt guilty about having him there since there wasn't anything wrong with him. Next appointment is in one year! Wow. Also-- Sam has finally been taken off of his daily dose of Lasix. He was down to 0.6 cc by mouth once per day. The only downer news this week is that Sam has come down with a cold-- lots of sneezing and congestion.
