Preoperative Left Atrial Mechanical Dysfunction Predicts Postoperative Atrial Fibrillation After Coronary Artery Bypass Graft Operation - A Velocity Vector Imaging-Based Study -
(JAPANESE CIRCULATION SOC, 2010)
Background: The aim of the present study was to evaluate pre-existent subclinical mechanical atrial dysfunction in patients with postoperative atrial fibrillation (POAF) by using novel echocardiographic techniques. Methods ...
Subclinical Left Ventricular Dysfunction in Asymptomatic Severe Aortic Regurgitation Patients with Normal Ejection Fraction: A Combined Tissue Doppler and Velocity Vector Imaging Study
(WILEY, 2010)
Objectives: Our aim was to evaluate subclinical left ventricular (LV) dysfunction, by two novel echocardiographic techniques, velocity vector imaging (VVI)-derived strain imaging and tissue Doppler imaging (TDI), in patients ...
