Post-TAVR Suicide Left Ventricle Pre-TAVR: High afterload from aortic stenosis leads to compensatory left ventricular hypertrophy and chronic pressure overload Post-TAVR: Rapid ↓ in afterload can lead to ↑↑ contractility from the chronically hypertrophied LV → cavity obliteration Treat like Hypertrophic Cardiomyopathy w/ Obstruction ✓ Ensure Adequate Preload ✓ Avoid Excessive Vasodilation ✓ Consider Phenylephrine to ↑ Afterload and ↓ Intra-Cavitary Gradients ✓ Continue Beta Blockers through TAVR: ↓ Inotropy + ↑ Diastolic Filling Time - Cardionerds - Karan Desai MD, MPH @karanpdesai #PostTAVR #Suicide #Left #Ventricle #diagnosis #management #pathophysiology #cardiology #treatment
