Delayed Valsalva obstruction after transcatheter self-expandable aortic valve implantation: a case report.

In this report, we describe delayed Valsalva obstruction after transcatheter self-expandable aortic valve implantation, which can be detectable by serial computed tomography. The sealing of a coronary cusp by a commissural post of the valve may be one of the causes of delayed coronary ischaemia after transcatheter self-expandable aortic valve implantation.
