Introduction
The diagnosis of PH should be based on clinical suspicious
and specific complementary tests. CMR has no acoustic
window limitation, it is the gold standard for quantifica-
tion of right ventricular (RV) function, it is the main test
for congenital heart disease (CHD) and finally it gives
more comprehensive information.
Purpose
To show how useful the CMR was for patients referred
for heart failure (HF), regarding the identification and
severity of pulmonary hypertension (PH) not previously
assessed by other non-invasive techniques.
Methods
We reviewed patients referred to our institution from
January 2008 to March 2010 for further evaluation of
HF who were firstly diagnosed of PH by CMR. The
study was performed on a 1.5T Avanto scanner and
included: cine images, phase-contrast sequence, time-
resolved angiography for aorta and pulmonary artery,
and inversion recovery sequence. The data analyzed was:
ventricular volumes and functions, flows, interventricu-
lar septum (IVS) motion, and assessment of late gadoli-
nium enhancement (LGE).
Results
20 patients were included. Eleven (55%) were female and
the mean age was 47. Following the Dana Point classifica-
tion 2008: 10 belonged to group 1; 4 to group 2; 1 to group
3; 1 to group 4; and 4 patients had mixed conditions. All
patients presented high RV volumes (end-dyastolic 209 ±
88 mL; and end-systolic 128± 81,7 mL). The RV ejection
fraction (RVEF) was 41 ± 16 %. The RV outflow tract was
enlarged (30 ± 5 mm) and pulmonary artery (PA) too
(36 ± 7,5 mm). RV wall thickness was 4,2± 1,4 mm.
Pulmonary peak velocity was 105,7 ± 76,8 mmHg, with
moderate regurgitation. IVS motion classified as: 50% flat-
tening, 35 % D-shaped, normal only in 1. The left ventricu-
lar (LV) overall function was related to the baseline disease.
The systolic RV/LV volume ratio was 1,9 ± 0,8 and the
diastolic one was 1,6 ± 0,6. LGE was present in 60%, mostly
in basal RV and LV insertion points; additionally in LV
inferior wall in one patient suggesting myocardial infarct,
and another patient presented transmural LGE in inferior
apical wall. CMR angiography was of value as it allowed
orthogonal measures of PA and showed features of chronic
thromboembolic disease, pulmonary vein stenosis and
discovered CHD.
Conclusions
CMR is able not only to diagnose PH but also provide
its severity and etiology, offering prognosis and guiding
management / follow-up within a single examination.
