of echocardiographic documentation to satisfy the needs to analyze different scenarios of aortic stenosis due to various flow conditions and pressure gradients. Transesophageal and multidimensional echocardiography ...
of coronary flow reserve measurements by transesophageal echocardiographic (TEE) Doppler recordings of coronary sinus or left anterior descending (LAD)coronary artery flow velocity for detecting stenoses ...
both in sinus rhythm and atrial fibrillation. Methods: We studied 38 patients with isolated severe mitral stenosis (mitral valve area index ≤0.75 cm2) by pulsed wave Doppler transesophageal ...
The specific flow pattern and imaging features of prosthetic heart valves poses major challenges for the Doppler echocardiographic assessment of prosthetic valve structure and function ...
. The aim of this study was to analyze the impact of concomitant AR on Doppler -derived guideline criteria. We hypothesized that both transvalvular flow velocity (maxVAV) and the mean pressure gradient (mPGAV ...
revealed a larger decrease in VTI1 due to higher initial awake-state VTI1 (22 ± 5.6cm), resulting in similar Doppler - velocity -index (DVI) and AVA decrease with TEE, despite slight increase in mean gradients ...
function should be performed in a systematic way, measuring transmitral flow , pulmonary venous flow , transmitral color M-mode flow propagation velocity , and mitral annulus tissue Doppler imaging. The unique ...
in left atrial and PV flow velocities following PV antrum isolation with GP ablation using transesophageal echocardiography (TEE). Methods: TEE was performed before and after PV antrum isolation with GP ...
diastolic function can also be evaluated by ABD, and the results complement those obtained indirectly by pulsed Doppler echocardiographic recordings of the diastolic mitral flow velocity . Recently, ABD has ...
