I had the great displeasure of seeing Dr. Clifton Watt (https://www.ucsfhealth.org/providers/clifton-watt) at UCSF's Cardiology department. I found him to have remarkably poor bedside manner. He was incredibly antagonistic and condescending. I would, personally, not visit Dr. Watt again. There are numerous cardiologists in San Francisco, and I imagine most will provide better care than him.
