Objectives: (1) To study the diagnostic accuracy of right ventricular (RV) echocardiographic (ECHO) parameters in detecting acute RV failure (2) To study RV ECHO characteristics in RV failure post heart transplant (OHTx).
Methods and Results: Right heart catheterization and ECHO were simultaneously performed in 20 consecutive de novo OHTx recipients (43 ± 13 years, male 70%, median pulmonary artery pressure= 28 mmHg, ischemic time=238±73 min) at 64±51 hours post operation. Of 20 patients, 15 (75%) had RV failure defined as mean right atrial pressure > 15 mmHg and CI <2 L/min/m2. The diagnostic accuracy of RV ECHO parameters for detecting hemodynamic criteria of RV failure is shown in TABLE 1. RV free wall longitudinal strain, RV index of myocardial performance (RIMP), and RV outflow tract (RVOT) TVI had the highest area under the curve. Segmental RV deformation abnormality with a marked reduction in peak systolic strain of mid segment of RV free wall was demonstrated in those with RV failure.
Conclusions: (1) RV failure post de novo OHTx was common (75%). (2) Segmental RV deformation abnormalities were characterized in OHTx patients with RV failure. (3) RV peak systolic strain, RIMP, and RVOT TVI, (not TAPSE, RVFAC, TV S’ or diastolic parameters), were the most useful parameters in detecting acute RV failure identified by hemodynamic criteria. (4) ECHO assessment of RV function using parameters and cut-off values according to the ASE/EACI recommendation needs a special caution in the setting of RV failure post OHTx.
