Figure 5 Two-dimensional apical four-chamber view of left ventricular (LV) end-diastolic and end-systolic cavity silhouettes at baseline (left) and >4 months after revascularization (right). (A) In a patient with no viable myocardium (viability index = 0.13), no recovery of function and no reverse remodeling at follow-up. (B) In a patient with substantial myocardial viability (viability index = 0.56) and eight segments that recovered function after revascularization. Marked reduction of LV end-diastolic and end-systolic volumes is appreciable at follow-up examination.
