U.S., March 18 -- ClinicalTrials.gov registry received information related to the study (NCT07477002) titled 'Post-Dilatation Effect on TAVI Prostheses Expansion' on March 03.
Brief Summary: Asymmetrical and inadequate expansion of trans-catheter heart valves (THVs) have been described as a key predictor of impaired valve hemodynamic performance predisposing patients for bio-prosthetic valve dysfunction (BVD) and death. Post-dilatation using the original delivery system balloon at the identical filling volume after deployment of balloon-expandable THVs represents an invasive strategy to potentially optimize expansion and reduce asymmetry of balloon-expandable THVs. Currently, the efficacy and safety of routine post-dilatation has never bee...
