ABSTRACT
Objective:
To compare the value of cardiac MRI (CMRI), ultrasonic cardiogram (UCG), multidetector CT (MDCT) in assessing right ventricular function (RV) in patients with PAH.Methods:
A total of 31 consecutive patients with PAH (17 males and 14 females, 55±12 years) in Beijing Chao-Yang Hospital from August 2012 to February 2014 were prospectively enrolled. All patients underwent CMRI to get parameters including right ventricular end-systolic volume (ESV), end-diastolic dimension (EDV), stroke volume (SV), ejection fraction (EF), ventricular mass index (VMI). UCG parameters included Tei index, RV fractional area change (FAC), ESV, EDV. MDCT parameters included right /left ventricular internal diameter (RVd/LVd), right /left ventricular diastole maximum area (RVa/LVa), Cobb angle.These parameters obtained by MRI, UCG and MDCT were correlated with those of RHC respectively by Spearman or Pearson correlation analysis.Results:
Six minutes walk distance had moderate negative correlation with CMRI-EF (40±9), VMI 44-115(71±20) g/m(2,) Cobb angle(67°±12°); RHC-SV had moderate negative correlation with CMRI-SV(57±21) ml, EF, VMI, UCG-EF(41±14), Tei(0.82±0.29), FAC(30±9), RVd(45±7) mm, RVa(2 484±596) mm(2), Cobb angle ; Right cardiac work index had moderate negative correlation with CMRI-EF, RVd and Cobb angle.Conclusions:
MRI-EF is the best parameter to reflect RV function. CMRI is the optimal method to assess RV function, and then is the MDCT and the last is UCG.Palabras clave
