Did work on my heart clog over 15 years ago now; annual checkups and stress-tests. Great doctor, explains everything and really useful on requirements of medications and self-monitoring of heart health. Met him first when he did the ER work on my heart at Scripps Memorial, been with him and his staff ever since.
