Thanks for checking on Sheldon's health status. Day #1 of our "adventure" begins today (Monday). We plan to leave for Suburban Hospital at about noon (Eastern), and he's scheduled for an echocardiogram at about 1 pm and an angiogram (catheterization) at about 3. The main event is on Tuesday, with the surgery scheduled for 6:30 am (which probably means 7). It's supposed to last about 4-5 hours, possibly longer, depending on what they find from the Monday tests.
We appreciate your thoughts and hope you will continue your tfilos, particularly during the times in question. We have set up a "Tehillim Yachad" whereby many chapters of Tehillim can be said in a short time by many people. Here's the link: http://tehilimyahad.com/mr.jsp?r=sL2R2ROwB7
I will try to give updates as regularly as possible.
