“…RV systolic strain was normal at rest in all groups and comparable to reported values of healthy 4–16-year-old children 34. In adults with normal LV function, RV peak systolic strain correlates with invasive measurements of mean PAP and pulmonary vascular resistance (r=0.59 and 0.60, respectively, both p<0.001) 35. Since in our study, no child had clinical or echocardiographic evidence of LV dysfunction, normal RV strain suggests normal RV haemodynamics at rest.…”

“…The relaxation time is prolonged during hypoxia 41. RV myocardial systolic strain is another surrogate marker of pulmonary hypertension because it correlates well with pulmonary vascular resistance 35 42. We assessed both these new, indirect markers: RV relaxation time increased with hypoxia to a similar degree in all three groups.…”

“…This is in discordance to our postoperative findings. In their study, there was no postoperative patient, and patients with prosthetic valves were excluded [11]. In the presented study, strain and strain rate showed the weakest correlations with PVR of all parameters tested, with almost no association in group 1 patients.…”

Non-invasive monitoring of pulmonary vascular resistance (PVR) in postoperative cardiac surgery patients might be useful, particularly for management of pulmonary hypertension. For this purpose, we sought to assess Doppler echocardiography in the intensive care setting. In 73 patients, hemodynamics was measured using both, invasive gold standard (pulmonary artery catheter), and non-invasively by Doppler echocardiography. Four Doppler parameters: (1) tricuspid regurgitant velocity/time-velocity-integral of right ventricular outflow tract (TRV/VTI(RVOT)), (2) tricuspid annular systolic velocity (S'), (3) tricuspid annular strain, and (4) tricuspid annular strain rate, were compared with invasive PVR, using linear regression analysis and receiver-operating-characteristics. Patients without (n = 25, group 1) and patients with elevated left ventricular filling pressure (wedge pressure ≥ 15 mmHg, group 2, n = 48) were compared. Correlations were (1) R = 0.874, P < 0.0001, (2) R = -0.765, P < 0.0001, (3) R = 0.279, P = 0.009, (4) R = 0.378, P = 0.001. TRV/VTI(RVOT) showed prediction of PVR >300 dyn*s*/cm(5) (area-under-curve 0.975, cut-off 0.245, sensitivity 100%, specificity 91%). Strain correlated with PVR in group 2 patients only. TRV/VTI(RVOT) and tricuspid annular systolic velocity (S'), are useful for non-invasive monitoring of PVR in postoperative cardiac surgery patients with or without elevated left ventricular filling pressure. Strain may be used in patients with elevated filling pressure.

“…These findings are particularly important, as previous observations have promoted echocardiography as a tool for the functional evaluation of patients with PAH [10,30]. In this context, strain echocardiography has been reported as a surrogate of pulmonary haemodynamics in smaller heterogeneous populations, including patients with PAH due to ischaemic LV failure or chronic thromboembolism [31].…”

PAH (pulmonary arterial hypertension) is the leading cause of fatal right ventricular failure. However, rarely detectable, cTnT [cardiac TnT (troponin T)] is a significant prognostic marker. Therefore the aim of the present study was to evaluate the usefulness of a novel high-sensitive cTnT (hsTnT) assay as a parameter for functional and prognostic evaluation of PAH patients. In 55 PAH patients (idiopathic, n=20; chronic thromboembolic, n=30; and interstitial lung disease, n=5) with a mean pulmonary artery pressure of 45+/-18 mmHg, cTnT was measured by a fourth-generation conventional assay and a novel hsTnT assay with a lower detection limit at 2 pg/ml [total imprecision <10% at the 99th percentile value (13.4 pg/ml)]. In 90.9% of patients, cTnT was detectable using the hsTnT assay and in 30.9% using the fourth-generation assay. Concentrations >99th percentile were observed in 27.3% using hsTnT compared with 10.9% using the fourth-generation assay. A total of five out of six patients with cTnT values >30 pg/ml (fourth-generation assay) or >29.5 pg/ml (hsTnT assay) died during the 12-month follow-up. There was a correlation between hsTnT and 6-min walk distance (r=-0.92, P=0.0014), right ventricular systolic strain (r=0.95, P=0.0018) and strain rate (r=0.82, P=0.0021). In AUC (area under the curve) analysis, hsTnT predicted death at least as effectively as hFABP (heart-type fatty-acid-binding protein) or NT-proBNP (N-terminal pro-brain natriuretic protein). Moreover, hsTnT predicted a WHO (World Health Organization) functional class >II better than NT-proBNP or hFABP. In conclusion, in PAH patients, the novel biomarker hsTnT is associated with death and advanced WHO functional class, and is related to systolic right ventricular dysfunction and an impaired 6-min walk distance.

Utility of Right Ventricular Tissue Doppler Imaging: Correlation with Right Heart Catheterization

Abstract: RV myocardial strain correlates significantly with pulmonary hemodynamics in patients with pulmonary hypertension and normal left ventricular function. However, there is no correlation with RV performance in patients with left ventricular dysfunction.
