Comment on Opioids After Surgery in the United States Versus the Rest of the World

Abstract

will require extended follow-up. Third, several large propensity-score matched registries showed lower short-term and midterm mortality in BE TAVR than SE TAVR, indicating potential performance difference between different valve designs. 6 However, these studies suffered from selection bias and thus needs to be confirmed in randomized trials. In an effort to optimize the pharmacological treatments, refine new-generation valves and designs, and develop better imaging-guiding strategies, we look forward to the improvement of long-term performance of TAVR. Until then, we can better determine which strategy to choose for patients with isolated aortic valve stenosis.
