A new disease entity: Atrial functional mitral regurgitation.

abstract：BACKGROUND:Fractional flow reserve (FFR) is a useful index for determining the functional severity of epicardial coronary artery stenosis as an invasive physiological method. Although intravenous adenosine 5'-triphosphate (ATP) is generally used as a hyperemic agent for FFR measurement in Japan, there are some concerns...
