IVL modifies calcium through use of shockwaves, which are a specific form of sonic pressure waves.
The shockwave waveform has a rapid increase of peak pressure for approximately one micro-second, followed by a small negative pressure trough.
In contrast to ultrasound technologies which are characterized by low amplitude but very high frequency waveforms, an acoustic pressure shockwave has a very high amplitude but low frequency.
But, right now we're in the early phases of the R&D program. In the meantime, don't miss the IVL application that heart teams are embracing already — maintaining transfemoral TAVR access through heavily calcified iliacs by using IVL.
