Echocardiographic evaluation of left ventricular wall motion before and after heart transplantation.
Forty transplanted hearts were retrospectively investigated before, immediately after, and 15 +/- 12 months after heart transplantation by two-dimensional echocardiography for the presence and course of left ventricular myocardial wall motion abnormalities. Fourteen heart donors who were brain dead because of subarachnoid hemorrhage formed group 1 (mean age, 35 years); 21 heart donors who were brain dead because of head injury formed group 2 (mean age, 29 years), and five heart donors who were brain dead because of head injury with an additional chest trauma formed group 3 (mean age, 28 years). Myocardial wall motion was examined in six different myocardial segments (inferior, septal, anterior, posterior, posterolateral, apical) and was quantitatively assessed by a modified score index system (score index 0 = normal wall motion; score index 1 = diffuse hypokinesia). Overall, 27 of the 40 heart donors showed mild to severe (9 of the 40) wall motion abnormalities, which improved shortly after heart transplantation (score index: 0.36 vs 0.18, p < 0.01), and remained improved 15 months after heart transplantation (score index: 0.15). Among the different study groups, a significant improvement occurred in the myocardial wall motion score index on a short-term and long-term basis in all the groups, except for group 2, regarding the long-term follow-up. This study concluded that brain-dead, potential heart donors often reveal mild-to-severe left ventricular wall motion abnormalities, which are readily detected and semiquantitated by two-dimensional echocardiography.(ABSTRACT TRUNCATED AT 250 WORDS)
