Abstract:
The long-term prognostic significance of left ventricular (LV) long-axis contraction was investigated prospectively in 65 consecutive patients aged 58+/-15 years with asymptomatic aortic regurgitation, normal LV ejection fraction at rest, and no coronary artery or aortic root disease. A complete transthoracic echocardiographic study was performed at baseline and 12 months later. In 24 of 65 patients with peak systolic wave velocity at the lateral mitral annulus (LatS)<9 cm/s, LV diameter (p<0.01), volume (p
