Abstract Background The Doppler effect has allowed the characterization of several vessels in maternal-fetal circulation that have been used for practical purposes. Our review of the literature showed a paucity of information about fetal pulmonary artery pressure (FMPAP) and its behavior in regard to gestational age (GA). The objectives of the study were to evaluate a formula to calculate the main FMPAP and its correlation with GA. Methods A total of 337 fetuses without obvious pathology were studied prospectively using Doppler evaluation of the FMPAP. Using the fetal main pulmonary artery Doppler acceleration time (FMPAT), we obtained the FMPAP using the following formula: FMPAP=90 – (0.62×FMPAT). Regression analyses, Pearson’s bivariate correlation and paired sample t-test were used when appropriate. Results FMPAT increases while FMPAP decreases with GA. Pearson’s correlation coefficient for FMPAP and GA was −0.544 (P-value<0.001) and for FMPAT and GA was 0.556 (P-value<0.001). FMPAP and FMPAT were highly correlated (R=−0.972; P<0.001). Conclusion Pulmonary artery pressure in the fetus decreases with GA.

<strong>Background:</strong> Increased blood flow may trigger pulmonary arterial wall inflammation, which may influence progression of pulmonary artery hypertension in patients with congenital heart disease. In this study, we aimed to investigate the correlation between preoperative inflammation markers and pulmonary arterial hypertension. <br /><strong>Methods:</strong> A total of 201 patients with pulmonary hypertension were enrolled in this study retrospectively; they had undergone open heart surgery between January 2012 and December 2013. Patients’ preoperative C-reactive protein (CRP), neutrophil to lymphocyte ratio, red blood cell distribution width, pulmonary pressures, and postoperative outcomes were evaluated.<br /><strong>Results:</strong> Patient age, neutrophil to lymphocyte ratio, red blood cell distribution width, and CRP were found to be significantly correlated with both preoperative peak and mean pulmonary artery pressures. These data were entered into a linear logistic regression analysis. Patient age, neutrophil to lymphocyte ratio, and CRP were found to be independently correlated with peak pulmonary pressure (P &lt; .001, P &lt; .001, and P = .004) and mean pulmonary artery pressure (P &lt; .001, P &lt; .001, and P = .001), whereas preoperative mean pulmonary artery pressure was found to be independently correlated with intensive care unit stay (P &lt; .001). No parameter was found to be significantly correlated with extubation time and mortality. Eighteen patients had experienced pulmonary hypertensive crisis; in this subgroup, patients’ mean pulmonary artery pressure and neutrophil to lymphocyte ratio were found to be significant (P = .047, P = .003). <br /><strong>Conclusion:</strong> Preoperative inflammation markers may be correlated with the progression of pulmonary hypertensive disease, but further studies with larger sample size are needed to determine the predictive role of these markers for postoperative outcomes.<br /><br />

Abstract We sought to examine the influence of clinically severe lower respiratory tract infection on pulmonary artery pressure in children having CHD with post-tricuspid left-to-right shunt, as it may have physiological and clinical implications. In a prospective single-centre observational study, 45 children with post-tricuspid left-to-right shunt and clinically severe lower respiratory tract infection were evaluated during the illness and 2 weeks after its resolution. Pulmonary artery systolic pressure was estimated non-invasively using shunt gradient by echocardiography and systolic blood pressure measured non-invasively. Median pulmonary artery systolic pressure during lower respiratory tract infection was only mildly (although statistically significantly) elevated during lower respiratory tract infection [60 (42–74) versus 53 (40–73) mmHg, (p < 0.0001)]. However, clinically significant change in pulmonary artery systolic pressure defined as the increase of >10 mmHg was present in only 9 (20%) patients. In the absence of hypoxia or acidosis, only a small minority (9%, n = 4) showed significant pulmonary artery systolic pressure rise >10 mmHg. In the absence of hypoxia or acidosis, severe lower respiratory tract infection in patients with acyanotic CHD results in only mild elevation of pulmonary artery systolic pressure in most of the patients.

Abstract Aims  Increased medial mitral annulus early diastolic velocity (e′) plays an important role in the echocardiographic diagnosis of constrictive pericarditis (CP) and mitral e′ velocity is also a marker of underlying myocardial disease. We assessed the prognostic implication of mitral e′ for long-term mortality after pericardiectomy in patients with CP. Methods and results  We studied 104 surgically confirmed CP patients who underwent echocardiography and cardiac catheterization within 7 days between 2005 and 2013. Patients were classified as primary CP (n = 45) or mixed CP (n = 59) based on the clinical history of concomitant myocardial disease. On multivariable analysis, medial e′ velocity and mean pulmonary artery pressure were independently associated with long-term mortality post-pericardiectomy. There were significant differences in survival rates among the groups divided by cut-off values of 9.0 cm/s and 29 mmHg for medial e′ and mean pulmonary artery pressure, respectively (both P &lt; 0.001). Ninety-two patients (88.5%) had elevated pulmonary artery wedge pressure (PAWP) (≥15 mmHg); there was no significant correlation between medial E/e′ and PAWP (r = 0.002, P = 0.998). However, despite the similar PAWP between primary CP and mixed CP groups (21.6 ± 5.4 vs. 21.2 ± 5.8, P = 0.774), all primary CP individuals with elevated PAWP had medial E/e′ &lt;15 as opposed to 34 patients (57.6%) in the mixed CP group (P &lt; 0.001). Conclusion  Increased mitral e′ velocity is associated with better outcomes in patients with CP. A paradoxical distribution of the relationship between E/e′ and PAWP is present in these patients but there is no direct inverse correlation between them.
