Figure 3: Grade of TVR in patients before and after LP implantation
The average change for the entire study population was an increase in TVR by 0.28 grades. However, subgroup analysis by LP implantation location revealed that the average increase in TVR was 0.04 grades, 0.25 grades, and 0.67 grades for the apical septum, high septum, and mid septum locations respectively.
