Figure 6 Longitudinal Trends for Left Heart Structures After Initial Intervention to Reintervention, Death, or Last Follow-Up
The solid dark lines represent overall trends from regression modeling, the dotted lines represent 2 SDs from the predicted trends, and the light lines indicate measurements for individual patients over time. There was no significant interaction between left ventricular endocardial length z-score and time, and thus a time trend line is not provided. AP = anteroposterior.
