Introduction: Pregnancy is contraindicated in women with pulmonary hypertension (PH), yet many still decide to pursue pregnancy. Hypothesis: We hypothesized improved maternal mortality with PH at our center’s cardio-obstetrics program and sought to identify factors to estimate the risk of major adverse cardiac events (MACE). Methods: Pregnant women with right ventricular systolic pressure (RVSP) ≥35 mmHg or tricuspid regurgitant velocity > 2.8 m/s on transthoracic echocardiogram (TTE) were identified. Women with intermediate to high probability PH by ESC criteria (TTE or catheterization, n = 70) were classified using the 6 th World Society of PH definitions. Results: In 70 women with PH (30 ± 6 years-old, RVSP 52 ± 16 mmHg) there were 12 (17%) with WHO Group 1 PH, 45 (64%) with Group 2 PH, 4 (6%) with Group 3 PH and 9 (13%) with Group 5 PH (Figure A). Baseline characteristics were similar except: Group 1 PH had 83% on prostacyclin (PC) therapy, higher RVSP (78 ± 20 mmHg vs. Groups 2 (46 ± 9), 3 (44 ± 2 mmHg) and 5 PH (48 ± 10mmHg), p<0.01), and compared to Group 2 PH, more Group 1 PH women were diagnosed pre-pregnancy (9 (75%) vs. 12 (27%), p = 0.01) and had cardio-obstetrics care (10 (83%) vs. 16 (36%), p < 0.01) (Figure B - E). There were no peripartum deaths, however 3 (4.3%) women with Group 2 PH had late mortality (7 ± 4 months post-partum). MACE occurred in 24 (34%) women and was more likely in those with: NYHA FC ≥ 2 (95% CI 4.7-57, p < 0.01), pre-eclampsia (95% CI 1.2-13, p = 0.03), RVSP >50 mmHg (95% CI 1.3-10, p = 0.02) and LVEF <50% (95% CI 1.1-8.8, p = 0.04) (Figure F). Preterm birth occurred in 32 (49%) pregnancies, with no neonatal mortality. Conclusion: To conclude, in a large single center cohort we report 100% 1-year survival in Groups 1, 3, and 5 PH, with most Group 1 PH patients on PC therapy and under cardio-obstetrics care. We identify Group 2 PH as an under-recognized group for adverse outcomes in pregnancy, with NYHA FC, pre-eclampsia, RVSP >50 mmHg and LVEF <50% associated with increased MACE.

Abstract Introduction Juvenile rheumatic heart disease (RHD) refers to RHD in patients &lt;20 years of age. There are no contemporary data highlighting the differences between juvenile and older RHD patients. Purpose We aim to report the age related differences in the pattern, and consequencies of valvular dysfunction in patients of RHD. Methods The 2475 consecutive patients of RHD diagnosed using clinical and echocardiographic criteria were registered prospectively from 2011 till December 2019. Patients were divided into 3 groups according to their age: Group 1 (Juvenile RHD), Group 2 (21–50 years), and Group 2 (&gt;51 years).The data concerning the socio-demographic and clinical profile were recorded systematically, and the nature and severity of valvular dysfunction was assessed by echocardiography. The data were analyzed using the Epi-InfoTM Software. Results Out of 2475 RHD patients, Juvenile RHD comprised of 211 (8.5%) patients. Group 2 and 3 comprised of 1691 (68.3%) and 573 (23.2%) patients respectively. Overall, 1767 (71.4%) patients were females, however this female predilection was less pronounced in juvenile RHD (55.5% females vs 44.5% males) as compared to older groups. Past history of acute rheumatic fever was more commonly recorded in Juvenile RHD group (37.9% vs 18.8% in group 2 and 10% in group 3, p=0.0001). At the time of registration, the presence of advanced heart failure symptoms (dyspnea class III and IV) (11.4% group 1 vs 13.9% group 2 vs 20.6% group 3, p&lt;0.0001), right heart failure symptoms (0.9% group 1 vs 2.5% group 2 vs 7.3% group 3, p&lt;0.01), thromboembolic events (0% group 1 vs 4.1% group 2 vs 3.3% group 3, p&lt;0.01), atrial fibrillation (2.8% group 1 vs 24.5% group 2 vs 45.9% group 3, p&lt;0.0001), and pulmonary hypertension (27.1% group 1 vs 40.3% group 2 vs 51.9% group 3, p&lt;0.01), were all more commonly recorded in non-juvenile older RHD groups. Multivalvular involvement was also less common in juvenile RHD (34.6% vs 42.4% and 44.5%, p=0.04). Mitral regurgitation was the most common lesion in Juvenile RHD followed by aortic regurgitation (68.7% and 40.2% respectively). Stenotic lesions (both mitral and aortic) were present more commonly in older age groups. Conclusion RHD is predominantly a disease of females, however the predilection is less common in juvenile patients. Juvenile RHD predominantly affects the mitral valve and mainly leads to regurgitant lesions. As the age advances, the complications of RHD, mainly heart failure symptoms, thromboembolic events, pulmonary hypertension, and atrial fibrillation, become more common.

Mitochondrial abnormalities are associated with developmental disorders, although a causal relationship remains largely unknown. Here, we report that increased oxidative stress in neurons by deletion of mitochondrial ubiquitin ligase MITOL causes a potential neuroinflammation including aberrant astrogliosis and microglial activation, indicating that mitochondrial abnormalities might confer a risk for inflammatory diseases in brain such as psychiatric disorders. A role of MITOL in both mitochondrial dynamics and ER-mitochondria tethering prompted us to characterize three-dimensional structures of mitochondria in vivo. In MITOL-deficient neurons, we observed a significant reduction in the ER-mitochondria contact sites, which might lead to perturbation of phospholipids transfer, consequently reduce cardiolipin biogenesis. We also found that branched large mitochondria disappeared by deletion of MITOL. These morphological abnormalities of mitochondria resulted in enhanced oxidative stress in brain, which led to astrogliosis and microglial activation partly causing abnormal behavior. In conclusion, the reduced ER-mitochondria tethering and excessive mitochondrial fission may trigger neuroinflammation through oxidative stress.
