“…It has previously been reported that the basal segment is more severely damaged than the apical segment in PAH patients, which is inconsistent with the results of the current study (22,23). This is likely to be due to the patients included in the studies.…”

“…Apical segment deformation was correlated with RV contraction measured by RHC and conventional ultrasound, suggesting that under long-term pressure, the level of damage in the RV apical segment was higher than in the RV basal segment. This is likely to be due to the anatomy of the basal segment, which is composed of smooth myocardial and more longitudinal muscle, while the apical segment is composed of trabecular and less longitudinal muscle (22,23). This means that the apical segment is more easily damaged than the basal segment under the same pressure (24,25).…”

Abstract. The aim of the current study was to evaluate the use of two-dimensional strain echocardiography (2DS) in quantifying right ventricular (RV) function in patients with pulmonary arterial hypertension (PAH). A total of 41 patients with PAH and 40 healthy control patients were recruited to the study. 2DS was used to determine the strain (ε) and strain rate (SR) of basal, middle and apical segments of the RV free wall. The aforementioned indicators were compared with measurements of RV function taken by conventional ultrasound and right heart catheterization. The ε and SR of all segments of the right ventricular free wall were significantly lower in the PAH group, as compared with the control group (P<0.05). In the PAH group, the ε and SR of the middle and apical segments were significantly lower compared with basal segments (P<0.01). The SR of the apical segments were positively correlated with the area and diameter of the right ventricular. The ε of the apical segments were positively correlated with RV area, diameter and systolic function. The ε and SR of apical segments were positively correlated with pulmonary artery pressure and pulmonary vascular resistance measured by right heart catheterization. These findings indicated that 2DS can accurately evaluate RV longitudinal systolic function.

Background and Aims: Abnormal Right Ventricular (RV) function affects the long term outcome and clinical symptoms in patients with mitral stenosis (MS). This study evaluates the immediate effect of Percutaneous Transmitral Commisurotomy (PTMC) on RV function. Methods: An observational, cross sectional study was done on 50 patients with rheumatic MS who underwent PTMC at Shahid Gangalal National Heart Center from Dec 2015 -Dec 2016. All underwent clinical evaluation and echocardiogram before and immediately after PTMC. Results: There was female preponderance with 66% being female. The mean age was 37.26 ± 10.63 years. There was immediate increase in the mitral valve area (MVA) from 0.87 ± 0.12cm2 to 1.54 ± 0.27cm2(p< 0.001). There was significant decrease in mean mitral diastolic gradient from 16.4 ± 8.8mmHg to 5 ± 1.5mmHg (p< 0.001), in the pulmonary artery systolic pressure 53.6 ± 21.83mmHg to 39.5 ± 14.67mmHg (p< 0.001), in the RV Tei index from 0.56 ± 0.08 to 0.40 ± 0.08 (p< 0.001). There was significant increase in TAPSE from 16.0 ± 1.50 to 18.6 ± 1.70 mm, (p<0.001) and the longitudinal velocity of excursion of the RV at the tricuspid annulus (RV S') from 13.69 ± 3.33 cm/sec to 15.31 ± 3.07 cm/sec (p< 0.001) Conclusions: Successful PTMC can improve RV function as shown by the improvement in PASP, RV Tei index, TAPSE and RV S'. Further larger population studies are required to confirm the findings. Long term studies are important to determine the prognostic significance of improvement in RV function.
