  Figure 3. The location of neural regulation. The left image shows the sites of neural regulation studied, including the vagus/sympathetic nerves in the neck, the vagus nerve in the spinal cord, and the sympathetic nerves in the renal and visceral arteries. The right image shows the symptoms targeted by neural regulation, including resistant hypertension, intractable arrhythmias, and heart failure. Created with BioRender.com.

  Figure 4. Methods for improving myocardial remodeling. One approach involves excision/ablation of internal cardiac tissues, including excision of interventricular septum, excision of muscle trabecula and intramyocardial cerclage radiofrequency ablation. Another approach involves altering the shape of the heart using materials, including organization filling, duct shaping, and soft material wrapping. Created with BioRender.com.
