Myocardial revascularization surgery is the most performed procedure to relieve angina and to improve life expectancy for those with cardiovascular diseases. External polyester stents have been used to prevent radial deformation of the vein grafts used but require another surgery to remove the external sheaths. Carmen Cecilia Tadini et al. develop films with bioabsorbable materials, such as cassava starch, to be used instead of the external stents as graft support in the myocardial revascularization surgery. This study assesses the compatibility with the ruthenium nitric oxide‐donor and performs an in vitro degradation of the starch films. The cover shows the biodegradable film. (DOI: 10.1002/app.41382 )
