Surgical aortic valve replacement is the gold standard treatment for symptomatic patients. This treatment has demonstrably proven to be both safe and effective. Over the last few decades, in an attempt to reduce surgical trauma, different minimally invasive approaches for aortic valve replacement have been developed and are now being increasingly utilized. A narrative review of the literature was carried out to describe the surgical techniques for minimally invasive aortic valve surgery and report the results from different experienced centers. Minimally invasive aortic valve replace- ment is associated with low perioperative morbidity, mortality and a low conversion rate to full sternotomy. Long-term survival appears to be at least comparable to that reported for conventional full sternotomy. Minimally invasive aortic valve surgery, either with a partial upper stemotomy or a right anterior minithoracotomy provides early- and long-term benefits. Given these benefits, it may be considered the standard of care for isolated aortic valve disease.展开更多

Methods： Fifty-six cases of simple atherosclerotic occlusive disease of lower extremity were divided into 3 types according to the location of occhision, including 17 cases of abdominal aorta-iliac artery, 18 cases of iliac-femoral artery, and 21 cases of inferior popliteal artery. Catheter and guide wire combined with blunt dissection and subtle banding were used to dredge the occluded vessels, and stents were implanted when interlayer appeared. Results： After the treatment, 46 cases of occlusion were dredged （82.1%）, 6 cases remained occluded with the same symptoms （10.7%）, and 4 cases had severer symptoms （7.1%）. Among the 46 successful cases, there were 16 cases of abdominal aorta-iliac artery （94.1%）, 16 cases of iliac-femoral artery （88.9%） and 14 cases of inferior popliteal artery, artery （66.6%）. There was no statistical difference between the abdominal aorta-iliac artery cases and iliac-femoral artery cases （P〉0.05）, but there was statistical difference between these two types and the inferior popliteal artery cases （P〈0.05）. In the successful cases, 9 cases of abdominal aorta-iliac artery （52.9%）, 10 cases of iliac-femoral artery （55.5%） and 10 cases of inferior popliteal artery （33.3%） had 5-10 cm of occlusion, with no statistical difference between the first two types （P〉0.05）, but with statistical difference between the first two types and the third type （P〈0.05）. Compared with the 14 dredged cases （71.4%）, the 7 cases （33.3%） of inferior popliteal artery cases had richer compensatory circulation （P〈0.05）. Conclusion： It＇s safe and effective to treat simple atherosclerotic occlusive disease of the lower extremity with interventional therapy. The location and length of occlusion and the abundance of compensatory circulation had effect on the therapy.展开更多
