Human cardiac AT-MSCs can polarize human macrophages into anti-inflammatory phenotype. Our findings suggest a new mechanism of action of AT-MSCs that could be relevant to the pathogenesis and treatment of myocardial infarction, atherosclerosis, and various cardiovascular diseases.

Video-assisted thoracoscopic left cardiac sympathetic denervation can be safely and effectively performed in most patients with life-threatening ventricular arrhythmias. This minimally invasive procedure is a promising adjunctive therapeutic option that achieves a beneficial response in most symptomatic patients. These results support the inclusion of thoracoscopic cardiac sympathetic denervation among the treatment armamentarium in all patients with ventricular arrhythmias refractive to conventional medical therapy.
