CardiacBackground: As high-risk cardiac patients frequently remain within hospital while waiting for surgery, the aim of the present study was to determine the role of preoperative length of hospital stay on mediastinitis, and also, to assess contemporary risk factors for this complication. Methods:...
Accuracy of Aortic Annulus Diameter Measurement: Comparison of Multi‐Detector CT, Two‐ and Three‐Dimensional Echocardiography Accuracy of aortic annulus diameter Measurement: comparison of multi-detector CT, two- and three-dimensional echocardiography. J Card Surg. 2016;31:18-22... H Tsuneyoshi,T...
Although the distances between the coronary ostia and the aortic annulus plane differed significantly between the two CT measurement methods used in this study, this had no negative effect on the choice of the prosthesis, since ...
Comparison of 3D-TEE and CT for measurement of aortic annulus diameters of patients with severe aortic stenosis Preoperative measurement of the aortic annulus is essential for performing transcatheter aortic valve implantation (TAVI). Inaccurate measurement of the ao... Comparison of DTEE and CT for...
Accurate measurement of the aortic annulus is important when approaching anaortic valverepair. Many clinical studies have shown that the dimension of the annulus is one of the most important parameters for recurrence ofaortic regurgitation(AR) and for valvereoperationat mid- and long-term follow-up...
Introduction:Accurate measurement of the aortic valve annulus is critical for proper valve sizing for the transcatheter aortic valve replacement (TAVR) procedure. While computed tomography angiography (CTA) is the widely-accepted standard, two-dimensional (2D) and three-dimensional(3D) transesophageal ech...
Aortic Regurgitation (AR) produces the entrance of an abnormal amount of blood in the left ventricle. This disease is responsible for high morbidity and mo
CT measurements were indexed to echocardiographic aortic valve annulus area and square-root transformed for the analysis. RESULTS. Of 234 patients, the mean age was 64±11 years, and 64% were men. There were positive correlations of indexed calcific volume, noncalcific volume, and inverse ...
Measurement of TAC In addition to variations in the extent of the ascending thoracic aorta included, different methods for measuring TAC have been reported. The simplest method is to consider TAC as binary. Alternatively, TAC can be expressed continuously via the Agatston method, similar to a CAC...
Initial aortic annular measurement permitted a 25 mm valve sizer. The left atrium (LA) was opened along the intra-atrial groove, however satisfactory visualization of the mitral valve was not possible. We then proceeded to incise the right atrium and inter-atrial septum to improve exposure of ...
