Abstract
Introduction The development of pulmonary hypertension (PH) and right ventricular (RV) failure worsens the prognosis of severe aortic stenosis (AS) undergoing aortic valve surgical or interventional treatment. Therefore diagnostic RV imaging is of great importance to improve the risk stratification and the outcomes in this group of patients. Aims and Objectives To investigate changes of RV size and function in severe AS with PH using 2D echocardiography (2D echo) and cardiac magnetic resonance imaging (CMR). Materials and methods 30 patients with isolated severe AS (aortic valve area <1 cm2) underwent 2D echo and CMR before surgical aortic valve replacement. According to systolic pulmonary artery pressure (sPAP) patients were divided into two groups: I group – sPAP ≥ 45 mmHg (n = 7), II group – sPAP < 45 mmHg (n = 23). Indices of RV volumes, ejection fraction (EF) were analysed by CMR. End diastolic RV diameter and indices of RV free wall longitudinal function (TAPSE and s’) were analysed by 2Decho and compared between groups. Echocardiographic parameters of RV size and function were compared with CMR parameters. Statistical analysis was performed using SPSS version 23.0. Results There was no significant difference between groups in 2D echo derived end diastolic RV diameter (39 ± 3.4 vs 37 ± 3.5mm, p= 0.14). However, CMR indices of RV end-systolic volume (55.9 ± 21 vs 29.9 ± 10 ml/m2, p=0.005) and RV end-diastolic volume (94.0 ± 19 vs 64.1 ± 16 ml/m2, p=0.005) were significantly larger in PH group patients and they did not correlated with 2Decho derived RV size (p>0.05). Indices of RV free wall longitudinal systolic function, estimated by 2Decho in both groups were within normal values, although TAPSE and s’ were lower in PH group patients (TAPSE 19.8± 3.6 vs 23.5 ± 3.0 mm, p = 0.045, s’ 10.5 ± 3.6 vs 13.3 ± 3.7 cm/s, p= 0.018). CMR derived RV EF was significantly lower in PH group patients[...].
