Aortic valve replacement (AVR) produces dramatic acute changes in left ventricular loading conditions that may provide a substrate for dynamic left ventricular outflow tract (LVOT) obstruction, particularly in the context of inotropic stimulation. This and related abnormalities have been described postoperatively, but their occurrence intra-operatively immediately post AVR has not been examined. To assess the prevalence and clinical impact of this phenomenon, intra-operative transesophageal echocardiography (TEE) was performed in 72 patients undergoing aortic valve replacement (AVR) for aortic stenosis (n=28) aortic regurgitation (n=15), or mixed aortic valve disease (n=29). There were 31 bioprostheses, 23 mechanical valves, and 18 homografts/autografts. |
