OC02 AUTOMATIC 3D-ECHO AORTIC ANNULUS MEASUREMENT FOR A PRECISE PREOPERATIVE TAVI PLANNING: IS IT ALREADY FEASIBLE?Background and aim: Transcatheter aortic valve implantation is a wide-spreading technique. The advent of recent softwares based on 3D transoesophageal echo is updating the ...
Aortic annular measurement by (a) transthoracic echocardiograpy: parasternal long-axis view with measurement shown.bTransesophageal echocardiography (TEE): long-axis view shown with annular measurement. Transthoracic echocardiography (TTE) typically underestimates the aortic annulus by approximately 1.0–1.5 ...
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 ...
Correlation for each measurement was assessed using linear regression with the following results: intraobserver at sinuses of Valsalva (R2 = 0.94) and ascending aorta (R2 = 0.97) and interobserver at the sinuses of Valsalva (R2 = 0.93) and ascending aorta (R2 = 0.94). ...
Determination of sources of error and improvement in accuracy of left ventricular mass measurement by echocardiography Following analysis of correlation of interventricular septum (IVS), LV internal dimension (LVID), posterior wall (PW) and LVL between echo and CMR, a ... S Najmul,V Sunil,NAA ...
The purpose of this study was to s the value of MRI for measurement of pulmonary autograft diameters after transplantation to the aortic root in adults. Thirty-eight adults underwent this operation. MRI and trans-esophageal echocardiography (TEE) were performed in 30 and 27 patients, respectively,...
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...
