目的：在采用双腔技术的心脏移植（HTx）中，整个右心房（RA）是供体组织，而左心房（LA）由供体和受体组织两者组成。该研究的目的是描述与健康对照相比的心房功能，并确定功能障碍的决定因素。设计：回顾性纳入43例患者和30例对照。在右心导管插入术（RHC）（HTx受者）后24小时内进行超声心动图检查。结果：心房纵向收缩期峰值应变（）反映心房储血功能。与对照组相比，LA和RA储血器功能降低（LA- 18 +/- 8 vs 44 +/- 10%; RA- 22 +/- 10 vs 69 +/-17%，p
Objectives: In heart transplantation (HTx) with the bicaval technique the whole right atrium (RA) is donor tissue while the left atrium (LA) consists of both donor and recipient tissue. The aims of the study were to describe atrial function in comparison with healthy controls and to identify determinants of dysfunction. Design: Forty-three patients and 30 controls were retrospectively included. Echocardiography was performed within 24 h of right heart catheterization (RHC) (HTx recipients). Results: The peak longitudinal atrial systolic strain () described the atrial reservoir function. The LA and RA reservoir function were reduced versus controls (LA- 18 +/- 8 versus 44 +/- 10%; RA- 22 +/- 10 versus 69 +/- 17%, p
