BACKGROUND: Coronary angioplasty should be based on documented @entity63 . However, in daily clinical practice the indication for angioplasty is often based on eyeball assessment of the severity of the @entity850 . This study was performed to assess the accuracy of eyeball estimation of @entity3979 when taking functional flow reserve (FFR) as gold standard. METHODS: Study lesions were where no mutual agreement on the severity of the @entity850 was obtained. The procedure consisted of a repeat control angiogram, FFR measurement and in case of FFR<75% percutaneous coronary intervention. The eyeball assessment of the @entity850 was written down before further execution of the procedure. FFR was measured with a pressure monitoring guide. Maximal @entity296 was induced by intravenous @entity859 infusion. RESULTS: Fifty-two @entity1 were studied. Agreement between eyeball assessment and FFR existed in a total of 36 cases (69.2%). Over estimation of hemodynamic severity occurred in six cases (11.5%) and under estimation in 10 cases (19.2%). Consequently, the positive predictive value of eyeball assessment for pressure-derived FFR was 63% and the negative predictive value 76%. CONCLUSION: The assessment of the hemodynamic severity of intermediate @entity3979 should not be based on eyeball assessment even by experienced interventional cardiologists.

How good are experienced cardiologists at predicting the hemodynamic severity of XXXX when taking fractional flow reserve as the gold standard.
