Normal lv intracavitary gradient
WebThe LV intracavitary gradient at rest assessed by transthoracic echocardiography significantly decreased postoperatively (16.8±19.1mmHg vs. 107.4±52.5mmHg, p<0.0001). Actuarial freedom rates from cardiac death were 92.8%, 89.0%, and 80.1% at 5, 10, and 15 years postoperatively, respectively. WebThese patients may develop hyperdynamic ventricular function in an effort to maintain cardiac output in the setting of normal LV systolic function. Here is the sequence of events in this setting: Hyperdynamic LV function; Vigorous blood ejection at a higher velocity than normal; An increased intracavitary gradient; This may be mistaken for an ...
