Why the study?
It was unknown whether longitudinal strain values differ between the left and right ventricles during long-term follow-up after heart transplantation.
Does longitudinal strain differ between the left and right ventricles in long-time follow-ups after heart transplantation compared to controls?

Reduced post-HTx biventricular strain (greater in RV) remains stable to 5 years; leaves open whether routine strain monitoring refines surveillance in stable recipients.
Does longitudinal strain differ between the left and right ventricles in long-time follow-ups after heart transplantation compared to controls?
Heart transplant patients exhibit persistently reduced left and right ventricular longitudinal strain up to 5 years post-transplant despite preserved left ventricular ejection fraction, with more pronounced impairment in the right ventricle.
