Comparison of Aortic Annulus Diameter Measurement between Multi-Detector Computed Tomography and Echocardiography: A Meta-Analysis
BACKGROUND AND PURPOSE Accurate measurement of aortic annulus diameter is crucial for choosing suitable prosthetic size for transcatheter aortic valve implantation (TAVI). Several imaging methods are available for the measurement, but significant variability between different modalities has been observed. The purpose of this study was to systematically compare the measurements of aortic annulus...
متن کاملDetermination of Diameter and Angulation of the Normal Common Bile Duct using Multidetector Computed Tomography
BACKGROUND/AIMS Common bile duct stones are associated with the extent of dilation of the common bile duct as well as its angulation. Multidetector computed tomography (MD CT) has a good resolution for the definition of the anatomical features of the common bile duct. METHODS The multiplanar reformation images of 398 patients that underwent multidetector CT for the diagnosis of disorders not ...
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...
متن کاملAutomated 3-dimensional aortic annular assessment by multidetector computed tomography in transcatheter aortic valve implantation.
OBJECTIVES This study sought to evaluate the accuracy, reproducibility, and predictive value for post-procedural aortic regurgitation (AR) of an automated multidetector computed tomography (MDCT) post-processing imaging software, 3mensio Valves (version 5.1.sp1, 3mensio Medical Imaging BV, the Netherlands), in the assessment of patients undergoing transcatheter aortic valve implantation (TAVI)....
متن کاملSex differences in aortic valve calcification measured by multidetector computed tomography in aortic stenosis.
BACKGROUND Aortic valve calcification (AVC) is the intrinsic mechanism of valvular obstruction leading to aortic stenosis (AS) and is measurable by multidetector computed tomography. The link between sex and AS is controversial and that with AVC is unknown. METHODS AND RESULTS We prospectively performed multidetector computed tomography in 665 patients with AS (aortic valve area, 1.05±0.35 cm...
