Adenosine-induced atrial fibrillation during fractional flow reserve measurement.

We present the case of a 44 year-old man referred for coronary angiography with a history of coronary artery disease. Following administration of intra-coronary adenosine for fractional flow reserve (FFR) assessment, the patient developed atrial fibrillation (AF). While well described during non-invasive stress testing, this is the first description in the literature of AF following adenosi...

Coronary pressure measurement and fractional flow reserve.

The shortcomings of coronary arteriography to assess the physiological significance of coronary stenoses have been recognised for decades ; therefore, the importance of additional physiological techniques is beyond doubt. One of the currently available physiological techniques is coronary pressure measurement, which has emerged over the past few years as a major step forward in the invasive ass...

Impact of Right Atrial Pressure on Fractional Flow Reserve Measurements: Comparison of Fractional Flow Reserve and Myocardial Fractional Flow Reserve in 1,600 Coronary Stenoses.

OBJECTIVES This study sought to assess the impact of a wide range of mean right atrial pressure (Pra) on fractional flow reserve (FFR) measurements. BACKGROUND FFR invasively assesses the ischemic potential of coronary stenoses. FFR is calculated as the ratio of mean distal coronary pressure (Pd) to mean aortic pressure (Pa) during maximal hyperemia. The Pra is considered to have little impac...

Fractional flow reserve measurement modification with monorail pressure catheter.

A number of symptomatic patients with coronary artery disease undergo revascularization without definite evidence that particular coronary stenosis is responsible for their symptoms [1]. Currently, the borderline coronary artery stenoses are most commonly assessed by intravascular ultrasound and fractional flow reserve (FFR) alongside with quantitative coronary angiography [2]. FFR measurement,...

Pressure-derived measurement of coronary flow reserve.

OBJECTIVES We aimed to validate the technique of measuring the coronary flow reserve (CFR) with coronary pressure measurements against an established thermodilution technique. BACKGROUND The CFR has traditionally required measurement of coronary blood flow velocity with the Doppler wire and, more recently, using a thermodilution technique with the coronary pressure wire. However, recent work ...
