“…Additional support for this premise was reflected in the greater RV SW values seen in the IV septal-ablated sheep during RV patch actuation, which also explains, by way of reciprocation, the lower RV SW values observed in the PTSMA sheep during univentricular LV DCC (Figure 4). Our previous studies have shown that cardiomyoplasty can also enhance external SW. 28 We have previously shown, under closed chest conditions, that PTSMA alone leads to prolonged Tau. 17 However, we did not observe this in the present study, in which Tau was paradoxically reduced by IV septal ablation.…”
