Aortic Stenosis and Non-Cardiac Surgery / by Muhammad Amir Ayub

Had to revise back this topic: the pathophysiology, diagnosis, severity and perioperative management/aims. Since it hasn't been uploaded yet, it seemed like a good opportunity to do so. I'm really having trouble cramming before the exams, so I'm just focused on remembering that the grading of the severity based on the (functional) AVA can be based on the cutoffs of 1, 1.5 and 2.6 cm2, and based on the peak gradient (which is derived from catheterization) the cutoffs are 10, 40, 65 mmHg.

I also came across a pretty good video on PA catheter insertions from the New England Journal of Medicine, so I thought I'd also share it here. Which also made me realize that I barely remember what I've studied about pulmonary hypertension weeks earlier. How the hell am I supposed to move on to another topic when everything I study just enters my mouth and leaves with my piss?

My brain just doesn't have the stamina to cram... For every 1 minute of studying I'm doing probably at least twice that doing anything else. And exams are in just 2 weeks' time. Yikes.
