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.

Peripheral Pulmonic Stenosis

AbstractA common systolic ejection murmur of the neonate has been attributed to physiologic peripheral pulmonic stenosis. We investigated this auscultatory finding using duplex pulsed Doppler. Three groups of normal fuliterm neonates less than one week old were studied—10 without murmurs, 10 with grade 1/6 murmurs and nine with at least grade 2/6 murmurs. We measured the anatomical size and peak flow velocities in the main pulmonary artery and left and right branches, the peak velocity in the right ventricular outflow tract, and the bifurcation angle. Flow gradients were calculated as 4 (Vmax)2 Groups were compared by t-tests. A loud peripheral pulmonic stenosis murmur was associated with increased pulmonary artery velocities, with left pulmonary artery velocity the most discriminating variable (1.3 ± 0.29 vs 0.94 ± 0.19 m/s; p ≤ 0.05). Although the peak gradient never exceeded 12 mmHg, there was an increased gradient in the loud murmur group (8.7 ± 2.6 vs 5.7 ± 2.2 mmHg; p ≤ 0.05) which may even be underestimated by the lack of angle correction. The left pulmonary artery diameter was also larger in the loud murmur group, but there were no other anatomic or volumetric flow differences between groups. The soft murmur group could not be separated from normals. We conclude that Doppler techniques can confirm the physiologic basis of peripheral pulmonic stenosis murmurs.

No. 11, p. 647).Schmorl, who discovered pulmonary artery embolism with cells later, identified this phenomenon as the cause of eclampsia in pregnant women. Lubarsch considered embolism as a consequence of all sorts of seizures in pregnant women. Kasyanov, who found embolism in all pregnant women, suggested that this is a physiological phenomenon that occurs during every pregnancy. The author studied the lungs in 40 pregnant rabbits and was convinced that, under normal conditions, the rabbit does not have pulmonary embolism with shorts after.

Abstract Background Nowadays, Pulmonary Hypertension (PH) is one of the most pressing issues in cardiovascular disease. Subsequently, pregnant women have a high degree of risk of morbidity and mortality and this poses a big challenge. Studies show that very often PH occurs due to congenital heart disease and for this reason, it is recommended to avoid pregnancy or to terminate the pregnancy at an early stage. Women who choose to remain pregnant should be treated at specialized PH centers with the experience of managing PH during and after pregnancy. Purpose The main purpose of this study was to estimate the survival of pregnant pts with PH depending on the severity of PH and etiology. Methods 8336 women during delivery on admission were screened from the period spanning January 2014 to December 2016. Of this number, 4268 (51%) the medical records of pregnant women with cardiovascular disease were retrospectively reviewed to identify patients with coexisting PH and pregnancies. Data on 98 (1.18%) pts with PH were identified and included in the study. All patients' PH severity was measured by Doppler echocardiography. Pulmonary artery systolic pressure value of 35 to 50 mm Hg, 51 to 70 mm Hg, or greater than 71 mm Hg measured by echocardiography corresponded to the mild, moderate, or severe PH, respectively. Demographics, characteristics of PH and pregnancy, management and outcomes were as well analyzed. Results 54 cases (55%) were classified into WHO group 1, 40 cases (41%) in group 2 (reason –left heart disease), 4 cases (4%) in group 4 (reason - pulmonary thromboembolism), and none in group 3 or 5. The systolic pulmonary artery pressure was <50 mmHg in 70,4% of patients, 51–70 mmHg in 18,4% and ≥70 mmHg in 11,2% The median age was 28 years. All deaths occurred in women with PH in WHO group 1, with moderate or severe PH severity, and with NYHA grade of III to IV. Pulmonary vascular-targeted medications were used in all pts with severe PH and in some cases with moderate PH 14 pts (14%), but none was administered to pts with mild PH. During pregnancy, 9 pts took monotherapy of the sildenafil but 1 pregnant patient took a combination of therapy with iloprost. After delivery, 14 pts took monotherapy and 9 took combination therapy. This notwithstanding, 3 pts who took the combination therapy (3%), died within 15 days after delivery (9,14,15 days, respectively). All of them died from uncontrolled PH and heart failure after delivery. Conclusion Our study shows that maternal mortality is associated with the severity of PH. Mortality in pregnant patients with pulmonary hypertension is still the most discussed problem in cardiology and obstetrics. It is necessary to diagnose this disease at an early stage, prevent pregnancy in pts with severe to moderate PH as much as possible, continue observation, adequately apply therapy in order to help curtail this problem.

Venous thromboembolism (VTE), and specifically its manifestation – pulmonary embolism (PE) – is the most common direct cause of maternal mortality in the world and ranks 3-4th among the causes of maternal mortality in Ukraine. The multidisciplinary team (pregnancy heart team) established at two academic institutions in 2013, presents its experience of treating VTE in pregnant women and parturients, as well as analysis of common pitfalls of medical care for pregnant women with VTE. The group of pregnant women (parturients) with VTE consisted of 8 patients, 6 of whom were pregnant, 2 were parturients. In 2 pregnant women and 2 parturients with high-risk PE, 4 surgical procedures were performed (three open-heart surgeries – thromboectomy from pulmonary artery, one endovascular inferior vena cava filter implantation), including a pregnant woman (24–25 week) with a massive high-risk PE who underwent an urgent surgery – pulmonary artery thrombectomy and a tricuspid valve repair (with fetus in utero) with prolongation of pregnancy to 39 weeks and the birth of a healthy baby. One perinatal twin loss was observed in patient after extracorporeal fertilization and acute VTE. The main causes of the VTE are the underestimation of risk factors in preconceptional counseling, and the lack of pre-gravid preparation of women, as well as the prevention of the development of venous thrombosis in ante-, intra- and postnatal periods. The diagnosis of VTE and PE in time, and competent medical support provided for such women during pregnancy is a key to minimizing cardiovascular risks and reducing maternal mortality rates. The National Pregnancy Heart Team presents algorithms for primary and secondary prevention and treatment of VTE.
