title: Intravascular ultrasound-guided stenting of left main stem dissection after Medtronic Corevalve implantation.
abstract: Transcatheter aortic valve implantation (TAVI) implies the introduction, positioning, and deployment of a stented bioprosthesis in the (calcified) native aortic valve. We report an at first glance uneventful TAVI with the Medtronic Corevalve System, which was followed by transient electrocardiographic changes suggesting acute left main stem disease. The diagnosis of acute left main stem dissection extending from the left coronary cusp was firmly established by intravascular ultrasound. The ostium of the left main stem was successfully treated with intravascular ultrasound-guided placement of a drug eluting stent.
