Myocardial deformation and acute cellular rejection after heart transplantation: Impact of inter‐vendor variability in diagnostic effectiveness

Our objective was to investigate the impact of inter-vendor variability in the ability of myocardial strain analysis to detect acute cellular rejection (ACR) in heart transplant recipients.We performed serial echocardiographic examinations in 18 consecutive adult heart transplanted patients, in their first year post-transplantation, within 3 hours of the routine surveillance endomyocardial biopsies (EMB) in a single center. Myocardial strain was...
