Why the study?
What are the predictors of coronary obstruction following transcatheter aortic valve replacement for degenerative bioprosthetic surgical valves?
What are the predictors of coronary obstruction following transcatheter aortic valve replacement for degenerative bioprosthetic surgical valves?
Prior stentless or stented bioprostheses with externally mounted leaflets and a short VTC distance are key predictors of life-threatening coronary obstruction during aortic valve-in-valve procedures.
No takes yet. Share an insight, caveat, or question.
Short VTC distance and specific bioprostheses warrant preprocedural caution in valve-in-valve TAVR; hypothesis-generating and requires prospective validation.
Ribeiro et al. (2017) studied this question.
