Method and results: Follow-up transthoracic echocardiography (TTE) was performed 3 years after initial TTE in 20 ‘healthy’ HTX patients (13.2 years post-transplantation at time of follow-up) with normal ejection fraction and angiographically ruled out allograft vasculopathy. Grey-scale apical views were recorded and stored for automated offline speckle tracking (EchoPAC 7.0, GE) of the 16 segments of the left ventricle. Strain analysis was performed in 320 segments 34.3 ± 3.7 months after initial assessment. Automated tracking of myocardial deformation for determination of longitudinal systolic strain was not possible in 24 (7.5%) segments at baseline and in 32 (10.0%) segments at follow-up (P = ns). The left ventricular ejection fraction (LVEF) was 61.9 ± 8.1% at the initial examination vs. 62.8 ± 5.8% 3 years afterwards (P = ns). Global longitudinal peak systolic strain was -14.0 ± 4.0 vs. -14.4 ± 2.8%, respectively (P = ns)
.
Apparently, deformation values remain stable over the years as long as the LVEF is preserved

Estudo pioneiro no seguimento de transplantados com Strain. Fora os casos de rejeição, a ligação entre o Strain e a fração de ejeção se mantém confiáveis.
