Thank you for this. If I am looking at the FFR Waveform, where would you say I would be able to see "maximum hyperemia"?. Thanks!

@whiteboardandmarkercardiol2787 3 жыл бұрын

Thanks for watching. On the FFR waveform, try to pay attention to the diastolic drift (Drop in the diastolic pressures) and separation of the two waveforms which is very specific. When you say “maximum hyperemia” it is by definition two minutes into the test but you can see it as early as in the first 40-50 seconds. I hope this help..

@@whiteboardandmarkercardiol2787 Thank you for your response. So it would be the lower systolic pressure = max hyperemia, after the adenosine was given?

@whiteboardandmarkercardiol2787 3 жыл бұрын

@@AG-lk4lq not really. Its just a visual check to make sure everything is in proper place. The actual “maximum hyperemia” by definition will be spitted out by the computer as a final FFR ratio once you stop the recording. So, it is important that you keep the adenosine going for complete two minutes even if it is grossly positive in the first minute or so. Unless the patient start having severe symptoms or side effects..

How is the % quantified via angiography? How can one just “eyeball” and guesstimate the blockage %?

@whiteboardandmarkercardiol2787 2 жыл бұрын

Great question. You have to look and find the healthy segment and compare with lesion. Thats the reason why its always foiled with errors and we end up doing FFR.

Aren't stenoses 0.75-0.80 called the "gray zone"?

@whiteboardandmarkercardiol2787 3 жыл бұрын

Siluleko. Yes, you are right. The trials targeted 0.75 but the meta-analysis showed 0.80 or less is acceptable to intervene to decrease mortality and morbidity. Now the consensus it to treat 0.80 or less. Hope this helps

Hello sir. What is the rationale why they are using 2 wires or 3 wires during PCI?

@whiteboardandmarkercardiol2787 3 жыл бұрын

Hi. Not entirely sure about the question if I understood it correctly. During PCI we do use wires and the number and type of wires will differ with the complexity of the lesion. Happy to answer if you elaborate.. thanks

@whiteboardandmarkercardiol2787 3 жыл бұрын

@@millennialgamer239 . Here you go.... Putting two wires one in the side branch can serve three purpose (As per LOTUS trial) 1. Serve as a marker to recanulate the side branch if it gets pinched and no reflow. 2. Helps preventing the plaques shift into the side branch. 3. Gives body and stiffness to the side branch in case there is plaque shift leading to angulation and closure of the side vessel. I hope this help..
