Heart transplantation ten‐year follow‐ups: Deformation differentiation comparison of myocardial performance in left ventricle and right ventricle

Background We try to investigate whether the values of three‐dimensional principal longitudinal strain present differently between the left and right ventricles in patients with long‐time follow‐ups after heart transplantation (HTx). Methods and results Transthoracic echocardiography with three‐dimensional speckle tracking was performed at one‐, five‐ and ten‐year follow‐ups in 62 “healthy” HTx patients together with routine echocardiographic evaluation in 32 control group (CG) individuals. Longitudinal strain was applied in all subjects assessing without myocardium wall motion abnormality. Firstly, left ventricular ejection fraction preserved in HTx and had no significant difference in comparison with the controls (p > .05). 3D measurement showed obvious reduction in global (%: CG: −20.5 ± 3.5 vs. HT1y: −13.7 ± 4.6, HT5y: −14.4 ± 4.5, HT10y: −14.6 ± 4.7. p
