Synopsis
The doctors cover the current approaches to managing chronic angina before and after PCI, discuss how to differentiate ischemic heart disease from non-ischemic chest pain, and address the burdens faced by patients with complex atherosclerotic disease. A significant focus of the episode is on the role of the coronary sinus reducer, including procedure technique, risks, benefits, and its potential for treating both obstructive coronary artery disease and microvascular disease. The doctors also explore the logistics and challenges of enrolling patients in the COSIRA-II trial and speculate on the future impact of this device in clinical practice.
