Abstract:
Objective To investigate the shape and function of right ventricles in patients received heart transplantation(HT). Methods Sixty healthy volunteers(control group) and 31 HT patients(HT group) were enrolled, and the HT group was further divided into the nonrejected(HTn) group and the rejected(HTp) group based on the endomyocardial biopsy(EMB) results. All the participants received routine echocardiography. Single beat real-time three-dimensional echocardiography (sRT-3DE) was performed in all to evaluate parameters concerning modality and systolic function of participants' right ventricles. Results 1) Right ventricular stroke volume (RVSV) and right ventricular ejection fraction (RVEF) were significantly different among the groups[RVSV: control group vs HTn group vs HTp group was (56.18 ± 23.72)ml vs (36.08 ± 10.94)ml vs (26.22 ± 9.84)ml, P <0.0001; RVEF:control group vs HTn group vs HTp group was (62.09± 7.18)% vs (51.04 ± 7.58) vs (35.86 ± 9.86)%, P <0.00001=.2= When taking the influence of rejection into consideration,RVEF was proved to be a stable and sensitive indicator. Conclusions sRT-3DE can quickly assess shape and systolic function of right ventricle.RVEF was the most stableand sensitive among all the RV-related indicators and is a promising indicator in the clinic follow-up of HT patients.
