Range of Pulmonary Autograft Responses to Systemic Pressure Immediately After Ross Procedure

CONCLUSION: We quantified normal human autograft biomechanical responses to systemic pressure based on patient-specific material properties. Regions of peak stresses were observed in autograft sinuses and STJ regions, which corresponded clinically to locations of autograft dilation. Our results provide valuable information on predicting variations in patient-specific ex vivo FE models when population-based material properties are used in settings where patient-specific properties are unknown.PMID:34785871 | PMC:PMC8592523
