Stanford type A (proximal) aortic dissection accounts for ~60% of all aortic dissections
Classic treatment includes direct surgical replacement of the ascending aorta w/prosthetic graft (+/- AV aortic repair/replacement)
~20-30% of these patients (*institutional dependent) are considered poor candidates for surgery and receive only medical management, which innately results in substandard outcomes
In this study those who were considered poor candidates for surgical repair underwent novel endovascular treatment
Endovascular repair in this study was considered both appropriate and improved traditional medical outcomes in patients who were considered poor candidates

-Common life-threatening cardiovascular effects of cocaine intoxication include tachydysrhythmias, ventricular fibrillation, myocardial ischemia, and infarction.
-Emergency management of acute cocaine intoxication relies mainly on supportive and symptomatic treatment, w/liberal use of gamma-aminobutyric acid receptor agonists such as benzodiazepines.
-Intravenous lipid emulsion (ILE) therapy has been used successfully to treat cardiac toxicity associated with a variety of lipid-soluble drugs, such as local anesthetics, calcium/beta-blockers, tricyclic anti-depressants, and cocaine.
-The current hypothesis, called the “lipid sink” hypothesis, suggest that ILE infusion creates an expanded lipid phase in the plasma that absorbs the circulating lipophilic toxin and decreases the amount of free unbound toxin available to bind to the myocardium.
-When life-threatening cardiac arrhythmias (e.g. wide-complex tachycardia/prolonged QT) are not amenable to standard therapy (e.g. sodium bicarbonate/magnesium) consider ILE as a potential option to the current algorithm.
