Overview

As with any surgical intervention, surgical therapies for aortic stenosis carry risks and potential for complication. These complications commonly include vascular issues such as vascular complications and mitral valve injury.

Complications

Complications stemming from aortic stenosis surgical therapies primarily involve vascular complications.

The most preferable surgical closure method for this tenuous patient population is a perclose or angioseal closure. This particular closure method calls for a mandatory attention to the meticulous access technique. An antegrade approach may be a viable method in some patient populations. An example of such would be the venuous access with transseptal approach. This particular procedure can be done in a select population of patients. Many patients are unable to tolerate this approach as the hemodynamic effects of mitral valve incompetence is a stiff wire as it is placed across the mitral valve. Mitral valve injury can occur as a result of such rigidity.

Prognosis

30% reduction in gradient is expected as the immediate result of surgical intervention. Patient survival after repeat BAV is higher than that of untreated patients.
