Assessment of the immediate effects of cardiopulmonary bypass on left ventricular performance by on-line pressure-area relations.


BACKGROUND Pressure-volume relations have been established as useful measures of left ventricular (LV) performance. Application of these methods to the intraoperative setting have been limited because of difficulties acquiring LV volume data. Transesophageal echocardiographic automated border detection can measure LV cross-sectional area as an index of… (More)
