Abstract
Background and objective To study the characteristics of ventricular function in Pulmonary Hypertension (PH) Patients with different shape of Interventricular Septum (IVS) by cardiac magnetic resonance (CMR). Methods 36 PH patients diagnosed by right heart catheterization accepted CMR. According to the morphology of IVS, the patients were divided into two groups: the non-deformation group (10 patients) and the deformation group (26 patients). The ventricular function parameters were as follows: RV and LV end-diastolic volume index (EDVI), end-systolic volume index (ESVI), stroke volume index (SVI), cardiac index (CI), ejection fraction (EF), and myocardial mass index (MMI). Results ANOVA analysis showed that the differences of RVEDVI, RVESVI, RVSVI, RVCI, RVEF, RVMMI, LVEDVI, LVESVI, LVSVI and LVCI were significant among the three groups. Compared with control group, RVSVI (P=0.017), RVEF (P<0.001), LVEDVI (P=0.048) and LVSVI (P=0.015) decreased in IVS non-deformation group. Compared with IVS non-deformation group, RVEDVI (P<0.001), RVESVI (P<0.001), RVCI (P=0.002) and RVMMI (P=0.017) were increased in IVS deformation group; while RVEF (P=0.001), LVEDVI (P=0.003), LVSVI (P<0.001) and LVCI (P=0.029) were decreased. Compared with the control group, RVEDVI (P<0.001), RVESVI (P<0.001), RVCI (P=0.004) and RVMMI (P=0.003) were increased in the IVS deformation group, while RVEF (P<0.001), LVEDVI (P<0.001), LVESVI (P<0.001), LVSVI (P<0.001), LVCI (P<0.001) were decreased. Conclusion Ventricular function is different in PH Patients with different IVS shape. The IVS shape can represent the changes of ventricular function in PH patients.
