Abstract Introduction Preeclampsia (PE) is a multisystem disease affecting 2–8% of all pregnancies. Recently we found that the prevalence of antiphospholipid syndrome (APS) in PE patients at 13.9%. APS can be the cause of thromboembolic pulmonary hypertension. However, data on heart function and pulmonary pressure in PE and in PE with APS are sparse. Purpose We sought to investigate cardiac hemodynamics in this population. Method Between July 2016 and December 2018, we performed echocardiography in patients who had suffered from PE alone (n=102, age=32.6±4.8 y) or PE with APS (n=21, age=32.1±4.2 y) 3 months after delivery. APS was diagnosed according to the Sapporo criteria. Results The overall prevalence of APS was 17%. Right ventricular to right atrial pressure (RV/RA) gradient was significantly higher in PE + APS patients than in patients who had PE only (21.1±3.8 vs. 17.9±4.6mmHg, p=0.04, PE+APS vs. PE). The indexed volume of the left atrium (LA: 20.3±4.4 vs 23.5±5.5ml/m2, p=0.01, PE+APS vs. PE) and the birthweight of the newborn (1379.8±759.1 vs 1848.1±879.6.1g, p=0.02, PE+APS vs. PE) were lower in APS patients. Conclusion In patients with preeclampsia and APS, three month after delivery, pulmonary artery pressure was higher and the left atrium size smaller than in patients who had PE only. Conceivably this may reflects multiple subclinical clots in the pulmonary vessels in APS patients and may put these patients at an elevated risk of pulmonary hypertension later in life.

Thromboembolic Pulmonary Hypertension

Background: Balloon pulmonary angioplasty (BPA) is a novel treatment option for inoperable or persistent chronic thromboembolic pulmonary hypertension (CTEPH). Little is known about renal function in CTEPH patients undergoing BPA. Objectives: The aim of this study was to assess the frequency of contrast-induced acute kidney injury (CI-AKI) in patients with CTEPH undergoing BPA and to evaluate the relationship between hemodynamic and renal function. Methods: A total of 41 CTEPH patients were included and 250 consecutive BPA sessions were analyzed for frequency of CI-AKI. The serum creatinine (SC) concentration was measured and the glomerular filtration rate (GFR) was estimated using the Modification of Diet in Renal Disease equation before and 72 h after each BPA procedure. CI-AKI was defined as an increase of 25% or 0.5 mg/dL in SC from the baseline value within 48–72 h of contrast administration. SC and GFR were assessed before and after 3–6 months of completing the BPA treatment and correlated with hemodynamic parameters. Results: The SC concentration and GFR did not change significantly within 72 h after BPA (+1%, p = 0.921, and +4%, p = 0.112, respectively). CI-AKI was noted in 2 cases (0.8%). Significant improvement was noted in GFR (75.4 ± 21.2 vs. 80.9 ± 22.4 mL/min/1.73 m2; p = 0.012) in addition to improvement in right atrial pressure (RAP; 9.1 ± 4.1 to 5.0 ± 2.2 mm Hg; p < 0.001), mean pulmonary artery pressure (49.1 ± 10.7 to 29.8 ± 8.3 mm Hg; p < 0.001), cardiac index (CI; 2.42 ± 0.6 to 2.70 ± 0.6 L/min/m2; p = 0.004), and pulmonary vascular resistance (9.42 ± 3.6 to 4.4 ± 2.3 Wood units; p < 0.001). In a subpopulation of 12 patients with impaired renal function at baseline, the relative increase in GFR was significantly correlated with relative improvement in CI (r = 0.060; p = 0.037), RAP (r = –0.587; p = 0.044), and mixed venous saturation (r = 0.069; p = 0.012). Conclusions: Hemodynamically effective BPA procedures improve renal function in patients with CTEPH with a minimal risk of CI-AKI in the course of treatment.

Thromboembolic Pulmonary Hypertension

Abstract Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare disease which results from obstruction of the major pulmonary arteries by incompletely resolved or organized pulmonary emboli which have become incorporated into the pulmonary artery wall, eventually causing an increase in pulmonary vascular resistances. Pulmonary endarterectomy (PEA) is the treatment of choice. Careful pre- and post-operative management is essential for a successful outcome following PEA. In 1994, we started in Pavia a program in which members of a multidisciplinary team work in close interaction with the aim of increase experience in the challenging problems these patients present in the evaluative, surgical, and post-operative phases of their care. So far, 134 PEAs have been performed. Preoperatively, New York Heart Association (NYHA) class distribution was respectively 3-II, 56-III, and 75-IV; mean pulmonary artery pressure and pulmonary vascular resistances were 47 ± 13 mmHg and 1149 ± 535 dynes/sec/cm−5 respectively. The overall operative mortality has been 9.7% (in 2005 mortality rate was 4.5%). At present, 92% of the PEA patients are actively participating in the follow-up study. Follow-up visits are at 3 months after PEA, yearly for the following 5 years, and then at 7, 10, and 15 years postoperatively. Both early and late survivals were excellent. Survival rate at 3 months, 1 year, and 3 years were respectively of 89.5±2.7%, 87.3±3.0%, and 82.7±3.6%. Survival rates had not changed at 5, 7, and 10 years postoperative. Three months after PEA, 29 (58%) subjects were within NYHA class I, 18 (36%) in class II, and 3 (6%) in class III. At 1-year follow-up, 40 (80%) patients were within NYHA class I, 10 (20%) in class II. A statistically significant difference exists not only between the preoperative and the postoperative data (p <0.0001), but also between the functional status at 3 months and the other two postoperative controls (p <0.001). Table summarizes the results of hemodynamic tests collected at three months, one year and three years on the first 35 patients who completed the follow-up program.

Thromboembolic Pulmonary Hypertension

Background: There have been no systemic studies about right heart filling pressure and right ventricular (RV) distensibility in patients with chronic thromboembolic pulmonary hypertension (CTEPH). Therefore, we aimed to explore combinations of echocardiographic indices to assess the stages of RV diastolic dysfunction.Methods and Results: We recruited 32 healthy volunteers and 71 patients with CTEPH. All participants underwent echocardiography, cardiac catheterization (in patients with CTEPH), and a 6-min walk test (6MWT). The right atrial (RA) end-systolic area was adjusted for body surface area (BSA) (indexed RA area). RV global longitudinal diastolic strain rates (SRs) and RV ejection fraction (EF) were measured by speckle tracking and three-dimensional echocardiography (3D echo), respectively. All 71 patients with CTEPH underwent pulmonary endarterectomy. Of the 71 patients, 52 (73%) had decreased RV systolic function; 12 (16.9%), 26 (36.6%), and 33 (46.5%) patients had normal RV diastolic pattern, abnormal relaxation (stage 1), and pseudo-normal patterns (stage 2), respectively. The receiver operating characteristic curve analysis showed that the optimal cut-off values of early diastolic SR &lt;0.8 s−1 and indexed RA area &gt; 8.8 cm2/BSA had the best accuracy in identifying patients with RV diastolic dysfunction, with 87% sensitivity and 82% specificity. During a mean follow-up of 25.2 months after pulmonary endarterectomy, the preoperative indexed RA area was shown as an independent risk factor of the decreased 6MWT distance.Conclusions: Measuring early diastolic SR and indexed RA area would be useful in stratifying RV diastolic function.

Thromboembolic Pulmonary Hypertension

Abstract Background: Prothrombotic state and impaired clot dissolution can contribute to the occurrence of chronic thromboembolic pulmonary hypertension in primary antiphospholipid syndrome. Pulmonary endarterectomy - the surgical removal of the organized thromboembolic material from the proximal pulmonary arteries - is the procedure of choice and potentially a curative option for patients with chronic thromboembolic pulmonary hypertension, including patients with antiphospholipid syndrome. We report an exceptionally severe and complicated case with favourable outcome. Case presentation: We present a case of a successful high risk pulmonary endarterectomy in a 29-year-old female with primary antiphospholipid syndrome and end-stage chronic thromboembolic pulmonary hypertension. Despite highly complicated perioperative course an impressive improvement in symptoms and functional status was achieved. Conclusion: We hope that this complicated but successfully managed case of a combination of two rare diseases will arouse earlier suspicion and timely diagnosis for such patients and will encourage physicians to promptly refer the suitable patients to a pulmonary endarterectomy team. It is important to remember that severe thrombocytopenia may occur in patients with antiphospholipid syndrome

Abstract Aims Right atrial (RA) function largely contributes to the maintenance of right ventricular (RV) function. This study investigated the effect of balloon pulmonary angioplasty (BPA) on RA functions in patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH) using cardiac magnetic resonance imaging (CMRI). Methods and results CMRI and RV catheterization were performed before BPA sessions and at the follow-up periods in 29 CTEPH patients. Reservoir [RA longitudinal strain (RA-LS)], passive conduit [RA early LS rate (LSR)], and active (RA late LSR) phases were assessed by using cine CMRI and a feature-tracking algorithm. The relationships between the changes in RA functions and in brain natriuretic peptide (BNP) were evaluated in both the dilated and non-dilated RA groups. RA-LS (32.4% vs. 42.7%), RA LSR (6.3% vs. 8.3%), and RA early LSR (−2.3% vs. −4.3%) were improved after BPA, whereas no significant change was seen in RA late LSR. The changes in RA peak LS and in RA early LSR were significantly correlated with the changes in BNP (ΔRA-LS: r = −0.63, ΔRA-early LSR: r = 0.65) and pulmonary vascular resistance (PVR) (ΔRA-LS: r = −0.69, ΔRA-early LSR: r = 0.66) in the nondilated RA group. Conclusion The RA reservoir and passive conduit functions were impaired in inoperable CTEPH, whereas RA active function was preserved. BPA markedly reversed these impaired functions. The improvements in RA reservoir and conduit functions were significantly correlated with the changes in BNP levels and PVR in CTEPH patients with normal RA sizes.
