Acute Response of Right Ventricular Function to Iloprost Inhalations in Patients with Pulmonary Arterial Hypertension: Preliminary Evaluation 
with Cardiac Magnetic Resonance Imaging
Background and objective Pulmonary arterial hypertension (PAH) is a progressive disorder characterized by abnormally elevated blood pressure of the pulmonary circulation. Without treatment, PAH progresses rapidly to right ventricular (RV) failure and even death. Cardiac magnetic resonance imaging (CMRI) has been an accurate and reproducible tool to assessment of RV morphology and function, which are important factors in the prognosis of patients with PAH. The aim of this study is to investigate acute RV response to inhalation of aerosolized iloprost in patients with PAH using CMRI. Method From March 2012 to March 2014, 48 ...

Characteristics of Ventricular Function in Pulmonary Hypertension Patients 
with Different Shape of Interventricular Septum:
Preliminary Study with Cardiac Magnetic Resonance Imaging
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), ejec...
