Left Ventricular Distortion and Function in Patients with Right Ventricular Pressure Overloading

右室圧負荷疾患における左室形態と左心機能
Maeda Toshiaki
Descriptions
To evaluate the effect of left ventricular (LV) distortion on its pump function, two-dimensional echocardiographic short axis views of the LV cavity were analyzed in 20 normal subjects (group N) and 9 patients with right ventricular pressure overloading (group PH). Functional significance of LV distortion was evaluated by the efficiency (E) of systolic shortening of endocardial circumferential fiber length (ECL) in reducing LV cavity area
