This case series from our lab illustrates the concept of Acute Mechano-Cardiac Coronary Artery Disruption described earlier by @rajivxgulati in 2024. These cases demonstrate that in Takotsubo syndrome, extreme and opposing wall-motion abnormalities (dyskinesis adjacent to ate a hinge-point distortion of the coronary arteries, resulting in vessel disruption and a mechanically driven, “non-spontaneous” coronary artery dissection. doi.org/10.1016/j.jcmg…

@SharonneHayes @docsaw @HeartDocSharon @WomensHeartCS @DrJMieres @purviparwani @iamritu @KTamirisaMD #SCAD #WIHD25 ✨ evidence lacking on aspirin but most start aspirin and then can stop it in 30 days ✨ recurrent SCAD often occurs in another vessel ✨Cardiac rehab for SCAD ⛔️Avoid high intensity, competitive, endurance; controlled resistance training

Novel sign of #Takotsubo CM=“Dynamic coronary hinge” at intersection of hyperdynamic & akinetic wall segments @mmamas1973 @mirvatalasnag @SVRaoMD @GreggWStone @aayshacader @SandeepNathanMD @Drroxmehran @SrihariNaiduMD @DLBHATTMD @ziadalinyc @BinitaShahMD @djc795 #CardioTwitter

@jl35wilsonMD @AbbottCardio @rajivxgulati Yes, as relates to stress-induced CM. Seems like MB is same concept — like this case and the other one I posted recently 👇🏼 — not so “spontaneous”

Not so spontaneous #SCAD but instead a mechanistic term “acute mechano-cardiac coronary artery disruption (AMCAD) from stress-induced cardiomyopathy. Congrats @rajivxgulati @marysia_tweet ❤️ @MayoClinicCV

Dr. @rajivxgulati, et al offer a collection of observations that support an alternate hypothesis in many cases—that #SCAD is a secondary event instigated by SICM (Takotsubo and variants). Learn more here: bit.ly/3O9yYoQ #JACCAdvances #cvCAD
