Abstract
The invention provides a method and system for reconstructing a high-fidelity pressure waveform with a balloon catheter used in a heart. First, a balloon catheter having an air line is inserted into the aorta of the heart. The air line is then closed and sufficient air is introduced in order to equalize the pressure in the balloon catheter and the aorta. The AC components of the aortic pressure and the mean aortic pressure are detected separately and then added to form a high-fidelity pressure waveform. The high fidelity pressure waveform may be displayed on an oscilloscope, a patient monitor, or other suitable display.
