Key result
Intracoronary measurement using a guidewire-mounted pressure sensor successfully demonstrated pulsus alternans and an abnormal fractional flow reserve in the left anterior descending coronary artery.

Case Report (n=1)
Can pulsus alternans be demonstrated intracoronarily using a guidewire-mounted pressure sensor in a patient with biventricular systolic dysfunction?
This case report demonstrates the feasibility of detecting pulsus alternans directly within the coronary arteries using a standard pressure wire.
Michaels et al. (2000) conducted a case report in Biventricular systolic dysfunction and pulsus alternans (n=1). Intracoronary measurement using a 0.014" guidewire-mounted pressure sensor was evaluated on Demonstration of pulsus alternans and fractional flow reserve. Intracoronary measurement using a guidewire-mounted pressure sensor successfully demonstrated pulsus alternans and an abnormal fractional flow reserve in the left anterior descending coronary artery.
