本研究旨在确定通过实时三维超声心动图评估功能性二尖瓣反流(MR)患者二尖瓣幕状区体积(TnV)作为临床指标的价值。对27例功能性M R患者和4例无二尖瓣疾病的对照者进行实时三维超声心动图检查,以逐帧评价患者从收缩期前至收缩期末的TnV。
This study was designed to determine the value of mitral valve cuff volume (TnV) as a clinical indicator in patients with functional mitral regurgitation (MR) assessed by real-time three-dimensional echocardiography. Real-time three-dimensional echocardiography was performed in 27 patients with functional M R and 4 patients without mitral disease to frame-by-frame evaluation of TnV in patients from systolic to systolic.
