Instantaneous wave-free ratio (iFR) may have a role to play in the acute setting of primary PCI, a new analysis suggests. Agreement between an acute iFR evaluation of nonculprit arteries and one ...

WASHINGTON, DC (UPDATED)—Two late-breaking trials with a combined total of 4,500 patients are making the case for instantaneous wave-free ratio (iFR) measurement to guide decisions on whether or not ...

Even with a stone-age /U-equipped airplane, I have always preferred to file IFR for most flights. That’s for a number of reasons familiar to all instrument pilots. In order of priority, the top four ...

Is this a trick question? If you say there aren’t any prescribed takeoff minimums for Part 91 operators, you would be correct; however, just because something is legal doesn’t make it smart. You might ...
