Dr. Craig Smith - Which Patients Might Benefit from Transcatheter Aortic Valve Replacement?

Read Transcript

Well potentially any patient with critical aortic stenosis could benefit. Critical aortic stenosis is defined by the degree of narrowing and the opening of a valve, so it's a problem because the heart has to pump very hard to push blood through a small opening we have ways to define that. Once you have reached the point that you have critical aortic stenosis then potentially anyone could benefit from having valve replaced because it will extend life and relieve symptoms.

In our current understanding of TAVI, it is best applied in patients who have highest risk for surgery or who are at such high risk of surgery makes no sense. What's less clear is where it becomes a better trade off compared to lower risk surgery, and right now it's clearly, excellent in the high risk population less clear in lower risk population.
