The CNCR team will be attending HRS 2023 this year in New Orleans, LA. There are numerous presentations at HRS this year, not only from Washington University, but from many other centers as well.

We have compiled a list of all presentations at HRS about cardiac radiotherapy. We look forward to seeing everyone there to discuss and continue to learn about this important topic in EP and Radiation Oncology.

The CNCR team will be attending HRS 2022 this year in San Francisco, California and many abstracts submitted by CNCR have been accepted.

Cardiac radioablation is a growing topic of conversation in the EP and radiation oncology fields and, therefore, many presentations at HRS this year will be centered around this topic. We look forward to seeing everyone there and the conversation around this very important, emerging field.
