Mitochondrial DNA (mtDNA) is the circulating genome in mitochondria, and it is easy to accumulate oxidative damage, causing mitochondrial dysfunction, and then cell dysfunction, and even tissue and body pathological changes, leading to diseases. As a pro-inflammatory, inflammatory, and even predictive factor, mtDNA is directly involved in the inflammatory response and the pathogenesis of many diseases. This article aims to review the current pathogenesis of mtDNA damage and its pathogenic role in various human diseases.
A 71-year-old male presented with esophageal cancer and severe aortic valve regurgitation. Treatment strategies for such patients are controversial. Considering the risks of cardiopulmonary bypass and potential esophageal cancer metastasis, we successfully performed transcatheter aortic valve implantation and minimally invasive three-incision thoracolaparoscopy combined with radical resection of esophageal cancer (McKeown) simultaneously in the elderly patient who did not require neoadjuvant treatment. This dual minimally invasive procedure took 6 hours and the patient recovered smoothly without any surgical complications.
