Published in 2022 at "Catheterization and Cardiovascular Interventions"

DOI: 10.1002/ccd.30064

Abstract: Fractional flow reserve (FFR) pullbacks assess the location and magnitude of pressure drops along the coronary artery. The pullback pressure gradient (PPG) quantifies the FFR pullback curve and provides a numeric expression of focal versus… read more here.

Published in 2020 at "Cardiovascular Intervention and Therapeutics"

DOI: 10.1007/s12928-020-00673-3

Abstract: The physiological pattern of coronary artery disease as determined by pressure-wire (PW)-pullback is important for decision-making of revascularization and risk stratification of patients. However, it remains unclear whether inter-observer differences in interpreting PW-pullback data are… read more here.

Published in 2020 at "International journal of cardiology"

DOI: 10.1016/j.ijcard.2020.05.001

Abstract: BACKGROUND Identifying the individual hemodynamic significance of tandem coronary artery lesions can be complicated by the crosstalk phenomenon which occurs between serial stenoses under hyperemic conditions. Physiological assessments performed under resting conditions are considered to… read more here.

Published in 2019 at "Journal of the American College of Cardiology"

DOI: 10.1016/j.jacc.2019.07.072

Abstract: BACKGROUND Diffuse atherosclerosis is commonly observed in angiographically normal segments in patients with stable coronary artery disease (CAD). The distribution of epicardial resistance along the vessel can be evaluated using coronary physiology. OBJECTIVES The purpose… read more here.
