CT image-based engineering analysis of transcatheter aortic valve replacement.

چکیده
DESPITE THE INCREASED GLOBAL EXPERIENCE WITH TRANSCATHETER AORTIC VALVE REPLACEMENT (TAVR), there remain 3 major adverse events. Aortic rupture (Fig. 1), coronary artery obstruction (Fig. 2), and paravalvular leakage (PVL) (Fig. 3) may occur with valve implantation. Oversizing or excessive radial expansion force with the TAVR stent may cause aortic rupture, whereas insufficient dilation may lead to PVL and device migration. During TAVR implantation, native leaflet material may produce occlusion of the coronary ostia. A reliable prediction of the biomechanical interaction between native tissue and device in TAVR is crucial for the success of this procedure.

Transcatheter Aortic Valve Replacement: A Review Article
Transcatheter aortic valve replacement (TAVR) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. Since the initial PARTNER trial results, use of TAVR has been on the rise each year. New delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...

Computed tomography (CT) plays an important role in the workup of patients who are candidates for implantation of a catheter-based aortic valve, a procedure referred to as transcatheter aortic valve implantation (TAVI) or transcatheter aortic valve replacement (TAVR). Contrast-enhanced CT imaging provides information on the suitability of the peripheral access vessels to accommodate the relativ...

BACKGROUND Although computed tomography (CT) is commonly used for iliofemoral evaluation for transfemoral transcatheter aortic valve replacement, many centers worldwide use invasive angiography alone for this purpose. No study to date has evaluated the value of CT over angiography for the prediction of vascular complications. In addition, no data exist for the value of noncontrast CT. METHODS...
متن کاملRole of Advanced Cardiac Imaging in Transcatheter Aortic Valve Replacement Planning
INTRODUCTION The fast development of transcatheter aortic valve replacement (TAVR) would not have possible without the invaluable collaboration of multimodal cardiac imaging, particularly transesophageal echocardiography (TEE) and computerized axial tomography (CT scan). Given the elevated morbimortality associated with severe aortic stenosis (AS) presenting high surgical risk, an adequate sele...
متن کاملMultidetector computed tomography in transcatheter aortic valve implantation.
Aortic stenosis is a common disorder. Aortic valve replacement is indicated in symptomatic patients with severe aortic stenosis, as the prognosis of untreated patients is poor. Nevertheless, many patients pose a prohibitively high surgical risk and are not candidates for surgical valve replacement. Transcatheter aortic valve implantation (TAVI) is a novel method to treat selected high-risk pati...
