Selective ablation of the ligament of Marshall reduces ischemia and reperfusion-induced ventricular arrhythmias.

Both LOM LSPV denervation and LSG Denervation significantly reduce cardiac sympathetic nervous activity (lower LF: 1.05±1.14 vs 2.36 ± 2.34 ms 2 in group 2 and 0.51 ± 0.39 vs 2.24 ± 1.53 ms 2 in group 3; and LF/HF ratio: 0.35±0.21 vs 1.65 ± 1.04 in group 2 and 0.27±0.28 vs 1.42 ± 0.77 in group 3; all P<0.05) but neither had a significant effect on parasympathetic nervous activity though which showed an increasing trend (HF: 2.69±2.00 vs 2.01 ± 2.14 in group 2 and 2.66±1.74 vs 1.95 ± 1.60 in group 3, P>0.05).

Although the incidence of VF was not significantly lower in groups 2 and 3 (2/9, 1/13 vs 4/11, P = 0.268), it did show a decreasing trend ( Fig 5D ).
