Early changes in regional and global left ventricular function after aortic valve replacement. Comparison of crystalloid, cold blood, and warm blood cardioplegias.
BACKGROUND: The clinical effects of different cardioplegic methods on left ventricular (LV) function have not been fully elucidated, particularly in the setting of myocardial hypertrophy. METHODS AND RESULTS: Sixty-four patients (mean age, 62 +/- 12 years; 41 men, 23 women) who were undergoing elective aortic valve replacement (stenosis, 49; regurgitation, 15; concomitant coronary artery bypass grafting, 22), with LV mass index 230 +/- 70 g/m2, were randomized to the following groups: antegra...Expand abstract
