Figure 3. Apical four-chamber views of echocardiographic findings demonstrating reduced left ventricular systolic function, obtained six days post-procedure with an estimated ejection fraction (EF) of 30%. The left image shows the heart in end-diastole, with the left ventricle at maximal volume. The right image shows end-systole, demonstrating poor ventricular contraction with minimal reduction in LV cavity size.
