Abstract
Anatomical repair(AR)of transposition of the great arteries(TGA) has been done because of concerns of right ventricular function post-atrial repair. There is little information about LV function post-AR. This study assessed LV function in 3 patients post-AR. All had pulmonary artery banding, 2 VSD's and 1 coarctation. Mean age of repair was 2.75 yr., mean age at catheterization was 4.9 yr. LV erid-diastolic volume index (EDVI), end-systolic volume index(ESVI), stroke volume index(SVI), ejection fraction(EF), mass index (MI), end-diastolic pressure(EDP), peak systolic pressure(PSP), end-systolic pressure(ESP), peak systolic stress(PSS), end-systolic stress(ESS) & end-diastolic stress(EDS)were all calculated. From a monoexponential formula LV diastolic myocardial stiffness(KE) was calculated. The rate corrected VCF(MVCFC)-end systolic stress relationship was obtained. These are compares with 10 controls and significant differences are shown in the Table.
The 3 TGA patients had normal MCVCFc-ESS relationship although at low normal levels. Thus systolic function is normal but LV mass and diastolic function is abnormal postrAR. *Supp. by the B.C.Heart. Found.
