Figure 2:

Measurement of coronary CT angiography–derived left ventricular (LV) long-axis shortening (LAS) using a reconstructed four-chamber view. Images at (A) end diastole and (B) end systole in an 87-year-old woman with LV-LAS of −11.24%, an ejection fraction of 75%, and a Society of Thoracic Surgeons Predicted Risk of Mortality (STS-PROM) of 6.0% who remained alive after undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis. Images at (C) end diastole and (D) end systole in an 88-year-old man with LV-LAS of −5.54%, an ejection fraction of 67%, and an STS-PROM of 3.6% who died 9 months after undergoing TAVR for severe aortic stenosis.
