Compared to the echocardiography at 7 days, IVST and LVPWd at 6 months after treatment showed a trend to incrassation in the control group (9.6 ± 0.3 vs. 9.9 ± 0.4, P < 0.001; 9.6 ± 0.3 vs. 9.9 ± 0.5, P < 0.001) and had no significant change in the TPE group (9.6 ± 0.4 vs. 9.7 ± 0.4, P = 0.251; 9.5 ± 0.3 vs. 9.7 ± 0.2, P = 0.056), while LVIDd were found to be significantly decreased in the TPE group (45.4 ± 2.8 vs. 44.0 ± 1.5, P = 0.019) and had no significant change in the control group (45.0 ± 2.9 vs. 44.6 ± 3.0, P = 0.244).
