ACC.24: Coronary sinus reducer for the treatment of refractory angina: A randomised, placebo-controlled trial (ORBITA-COSMIC)
Aaysha Cader interviews Michael Foley and Rasha Al-Lamee about the results of the ORBITA-COSMIC trial presented at ACC 2024. Results showed that coronary sinus reducer relieved angina symptoms but lacked evidence of increased blood flow to the heart. While beneficial for refractory angina patients, its mechanism remains unclear.
