Post-TAVR aortogram: Transform it into a modern tool for prognosis and efficiency

Key Points

• Video densitometry after aortography can provide objective assessment of aortic regurgitation post-transcatheter aortic valve replacement (TAVR)
• Contrast density ratio between the left ventricular outflow track and proximal aorta (LVOT-AR) of >0.17 suggests greater than mild aortic insufficiency and correlates with echo findings
• LVOT-AR of >0.17 is associated with higher 30-day and 1-year mortality
