Abstract
The present invention relates to the field of cardiac disease, in particular to the assessment of coronary vessels, in particular to determine the mechanisms and patterns of blockage or restriction to the blood flow through a coronary vessel. The present invention provides diagnostic methods and devices to determine the condition of coronary artery disease, in specific to determine the functional pattern (focal or diffuse) of coronary artery disease.
Claims16
A computer-implemented method for quantifying the patterns of coronary artery functional disease in a coronary vessel from a patient under hyperaemic conditions, comprising the following steps:
- acquiring a set of relative pressure values obtained from:
- pressure values obtained at different positions along the coronary vessel between the ostium and the most distal part of the coronary vessel;
- relative to
- the pressure at the ostium of the vessel,
- mapping said set of relative pressure values along the coronary vessel length, and determining:
- the contribution of the relative pressure drop of the functional disease with respect to the relative pressure drop over the total length of the coronary vessel;
- and
- the extent of the functional disease.
A computer device for evaluating coronary artery disease in a patient under hyperaemic conditions, said computer device configured to generate an FFR curve based on a multiple of FFR values, which are relative pressure measurements from pressures obtained at different positions along the total length of the coronary vessel between the ostium and the most distal part of the coronary vessel, relative to the pressure at the ostium of the coronary vessel, and wherein said computer device is further configured to map said multiple of FFR values along the coronary vessel length, and to determine:
- the contribution of said FFR drop of the functional disease with respect to the FFR drop over the total length of the coronary vessel;
- and
- said extent of the functional disease.
