Left Ventricular 3-Dimensional Global Longitudinal Strain Predicts All-Cause Mortality in Patients With Heart Transplant.

ABSTRACT:

Background

The prognostic value of 3-dimensional (3D)-left ventricular global longitudinal strain (LVGLS) in recipients of heart transplant (HT) reremains unknown. This study aimed to determine whether 3D-LVGLS was the more powerful predictor of poor outcomes in recipients of HT compared with 2-dimensional (2D)-LVGLS.

Methods and results

All consecutive adult patients who received HT and underwent at least 1 comprehensive 2D and 3D transthoracic echocardiographic examination for clinical surveillance were retrospectively enrolled. The end point was all-cause mortality. Prognostic model performance was assessed according to the C-statistic. The 3D-LVGLS measurements were feasible in 294 of 342 patients with HT (86%). The median follow-up time was 53 months, and 44 HT redied.
