Failed TAVI in TAVI Implantation: TAVI Dislocation Followed by Ensuing Surgical Graft Resection
We are presenting a case report of failed valve-in-valve treatment of severe aortic stenosis. A control ultrasonography after TAVI implantation revealed a severe aortic regurgitation of the graft which was subsequently unresolved with postimplantation dilatation. Second TAVI was implanted with cranial dislocation to the aortic root. Patient underwent a CT examination to clarify the TAVI in TAVI...
متن کاملIntermediate TEE
Over 56,000 aortic valves are replaced annually in the United States, making AS the second most common reason for heart surgery, behind only coronary artery disease. The intraoperative echocardiographer plays a part in confirming the diagnosis of AS, quantifying its severity, and ensuring proper prosthetic valve function postoperatively. However, the aortic valve is only one component of the ao...
متن کاملAntithrombotic therapy in TAVI
Transcatheter aortic valve implantation (TAVI) carries a significant thromboembolic and concomitant bleeding risk, not only during the procedure but also during the periprocedural period. Many issues concerning optimal antithrombotic therapy after TAVI are still under debate. In the present review, we aimed to identify all relevant studies evaluating antithrombotic therapeutic strategies in rel...
متن کاملTEE - The Electronic Exercise
The Electronic Exercise (TEE) is an experimental adaptive learning system which uses knowledge structures to apply an intelligent tutoring algorithm and especially the representation of its surmise relation via HASSE diagrams to navigate within the learning material, to visualize the learning progress and convey the structure itself to the learner. TEE is implemented via dynamic HTML and comes ...
متن کاملComparison of aortic root dimensions and geometries before and after transcatheter aortic valve implantation by 2- and 3-dimensional transesophageal echocardiography and multislice computed tomography.
BACKGROUND 3D transesophageal echocardiography (TEE) may provide more accurate aortic annular and left ventricular outflow tract (LVOT) dimensions and geometries compared with 2D TEE. We assessed agreements between 2D and 3D TEE measurements with multislice computed tomography (MSCT) and changes in annular/LVOT areas and geometries after transcatheter aortic valve implantations (TAVI). METHOD...
