In 1981, UCSF cardiologist Melvin Scheinman performed the first catheter ablation on a human patient, guiding a catheter into the heart and delivering an electric shock to interrupt an abnormal rhythm. The procedure offered a non-surgical alternative to treating arrhythmias, which previously relied on medication or open-heart surgery. UCSF is now recognizing the 40th anniversary of this breakthrough and its lasting impact on cardiology.

Psychiatric clinicians in the US report a rising number of patients, some with no prior mental health history, who developed delusions or paranoid thinking after extended use of AI chatbots. Researchers say cases include people forming false beliefs, such as one documented by UCSF researchers involving a woman who believed she could communicate with a deceased relative through a chatbot. An Entrepreneur op-ed warns that founders, who are often isolated and prone to seeking validation, face heightened risk from AI tools built to agree with users.
