The present disclosure relates generally to the assessment and treatment of vessels, including for percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). For example, some embodiments of the present disclosure are suited for identifying the available intervention technique(s) suitable to achieve a desired outcome selected or input by a user. For example, in some implementations a method comprises receiving pressure measurements obtained by one or more intravascular pressure-sensing instruments positioned within a vessel of a patient; receiving an input from a user regarding a desired pressure value for the vessel of the patient; identifying an available treatment option based on the received pressure measurements and the desired pressure value; and outputting, to a display device, a screen display including a visual representation of the available treatment option. Related devices and systems are also described.
