A medical history of the major breakthroughs in cardiac medicine, from cardiac bypass to angiography to pacemakers to heart transplants to artificial hearts.  Interspersed are stories relating to himself and his family, as well as some of his patients.  I’ve always found books like this interesting,  and I did find this one illuminating, but I’m a big fan of Atul Gawande, another south Asian doctor and writer, and the inevitable comparison leaves this author coming up a bit short by comparison.  The descriptions of the medical breakthroughs sound a bit detached, and the plight of his patients and his own emotional reaction to their triumphs and failures lacked the warmth and compassion that I feel in Gawande’s books.  Still, I enjoyed it and would recommend it.
