Abstract Background Co-occurrence of Type II Abernethy malformation (AM) with Type 1 pulmonary hypertension (PH) is extremely rare. In these patients, management of AM leads to reversal of PH. Case presentation We report a case of 24-year-old male that presented with fever and dyspnea of insidious-onset. Initial X-ray chest revealed pulmonary edema, prominent pulmonary knuckle, and dilated right descending pulmonary artery. Two-dimensional echocardiography suggested raised pulmonary artery systolic pressure (145 mmHg) and pulmonary angiogram revealed findings suggestive of Type 1 PH. Treatment with Tab. Tadalafil-Bosentan (20/5 mg, thrice daily) was initiated, but no major relief was obtained. On day 10, dyspnea worsened. Routine ultrasound revealed splenomegaly. Further evaluation with Doppler of the portal vein was suggestive of portal hypertension, and arterial ammonia was found to be raised. Contrast-enhanced computed tomography of abdomen and pelvis demonstrated a single dilated (1.3 cm) and torturous venous shunt between right internal iliac vein and superior mesenteric vein. Thus, a definitive diagnosis of Type II AM was reached. The patient was stabilized and subjected to the shunt closure with ASD Cocoon stent graft and recovered well. Conclusion Our case demonstrates a rare but reversible cause of PH. Type II AM should be included in the differential diagnosis of a patient presenting with dyspnea and provisionally diagnosed as a case of PH.

The aim of this study was to evaluate the association between thyroid hormone levels, pulmonary hypertension (PH), and pulmonary artery systolic pressure (PASP) in euthyroid patients with coronary artery disease (CAD). A cross-sectional study was conducted in individuals who underwent coronary angiography and were diagnosed as CAD from March 2013 to November 2013. 811 subjects (185 women and 626 men) were included in this study. PASP was measured by transthoracic Doppler echocardiography. 86 patients were diagnosed as PH and had significantly higher free thyroxine (FT4) levels than those without PH. Multiple logistic regression analysis demonstrated an independent association of FT4 levels with PH after adjustment of gender, age, body mass index, systolic blood pressure, left ventricular ejection fraction, hypertension, and medication use of calcium channel blockers, ACE inhibitors, angiotensin II receptor antagonists, and nitrates. Serum-free triiodothyronine (FT3) and thyroid-stimulating hormone (TSH) were not associated with PH. Furthermore, multivariate linear regression analysis showed that FT4 levels emerged as an independent predictor for PASP, while FT3 and TSH levels were not associated with PASP. Our study demonstrated that, in euthyroid patients with CAD, FT4 was an independent risk factor for PH, and FT4 levels were independently associated with PASP.

The Impact

Objective: Severe aortic stenosis leads to increased pulmonary arterial systolic pressure. A controversy still remains regarding the impact of persistent pulmonary hypertension (PHT) on prognosis of patients undergoing transcatheter aortic valve implantation (TAVI). We sought to investigate the impact of persistent PHT on 2-year all-cause mortality of patients with severe aortic stenosis following TAVI. Methods: Patients with severe and symptomatic aortic stenosis (effective orifice area [EOA]≤1 cm 2 ) who were scheduled for TAVI with a self-expanding valve at our institution were prospectively enrolled. Prospectively collected echocardiographic data before and after TAVI were retrospectively analyzed in all patients. Pulmonary artery systolic pressure was estimated as the sum of the right ventricular to the right atrial gradient during systole and the right atrial pressure. PHT following TAVI was classified as absent if <35 mmHg and persistent if ≥35 mmHg. Primary clinical end-point was 2-year all-cause mortality defined according to the criteria proposed by the Valve Academic Research Consortium-2. Results: Hundred and forty patients (mean age: 82±9 years) were included in the study. The primary clinical end point occurred in 17 patients (12%) during a median follow-up period of 2 years. Mean pulmonary artery systolic pressure was reduced in all patients following TAVI (45±9 versus 41±6 mmHg, p<0.01). Mortality rate was higher in patients with persistent PHT compared to patients with normal pulmonary artery systolic pressure following TAVI (26% versus 14 %, p<0.01). Patients that reached the primary clinical end point had a higher post procedural mean systolic pulmonary pressure (43±9 versus 39±6 mmHg, p=0.02). In multivariate regression analysis, persistence of PHT (OR: 2.51, 95% CI: 1.109-7.224, p=0.01) was an independent predictor of long-term mortality. Conclusions: The persistence of pulmonary hypertension after TAVI is associated with long term mortality. Identifying the population that will clearly benefit from TAVI is still need to be validated by larger trials.

Abstract Chuvash polycythemia is characterized by a homozygous 598C>T mutation in VHL and up regulation of HIF-1α during normoxia. Disorders of chronic hypoxia may be complicated by the development of pulmonary hypertension. Because of the up regulation of the hypoxic response in Chuvash polycythemia, we postulated that there may be a tendency to increased pulmonary artery pressures in this condition as well. To test this hypothesis, we analyzed results for Doppler echocardiography in 15 patients with Chuvash polycythemia and 15 Chuvash individuals without polycythemia. The tricuspid regurgitation velocity (TRV) allows estimation of pulmonary artery systolic pressure. A TRV of 2.5 m/sec or higher corresponds to a pulmonary artery systolic pressure of at least 35 mm Hg (normal up to 32 mm Hg), while a TRV of 3.0 m/sec or higher to a pressure of at least 46 mm Hg. The results are summarized in the Table. Pulmonary artery pressures as estimated by tricuspid regurgitation velocity (TRV) in Chuvash subjects with and without polycythemia Chuvash polycythemia (n = 15) Controls (n = 15) P Age in years; mean (SD) 35 (17) 35 (17) 1.0 Female sex in no. (%) 8 (53%) 8 (53%) 1.0 Hemoglobin in g/dL; mean (SD) 16.7 (2.3) 13.3 (1.2) <0.001 TRV in m/sec; mean (SD) 2.2 (0.6) 1.4 (0.6) 0.001 TRV > 2.4 m/sec in no. (%) 4 (27%) 0 (0%) 0.1 Most of the patients with Chuvash polycythemia were receiving phlebotomy therapy and therefore many had hemoglobin concentrations in the upper normal range. Four of the patients with Chuvash polycythemia and none of the others had TRV ≥ 2.5 m/sec (range of 2.5 to 3.0), and mean TRVs were significantly higher in the patients with Chuvash polycythemia. Interestingly, the mean ± SD TRV in these 15 patients with Chuvash polycythemia was identical to the mean ± SD TRV that was recently reported in 195 American patients with sickle cell disease (Gladwin et al, NEJM2004;350:886), another hematological condition with a tendency to pulmonary hypertension. While the pulmonary arterial pressures detected so far in Chuvash polycythemia patients are lower than those in patients with primary pulmonary hypertension, our results suggest that pulmonary hypertension may be an unrecognized complication of Chuvash polycythemia.

Abstract Pulmonary hypertension develops in most forms of hereditary and chronic hemolytic anemia, including sickle cell disease, thalassemia, hereditary spherocytosis, and paroxysmal nocturnal hemoglobinuria, suggesting that there is a clinical syndrome of hemolysis-associated pulmonary hypertension. Retrospective studies from tertiary care referral centers suggest a prevalence of pulmonary hypertension in adults with sickle cell disease ranging from 20 to 40%. Despite the fact the elevations in pulmonary artery pressures are slight, morbidity and mortality are high. In adult sickle cell anemia patients, pulmonary hypertension is emerging as a major risk factor for death. We performed Doppler echocardiographic assessments of pulmonary-artery systolic pressure in 80 consecutive patients (20 men and 60 women; mean [±SD] age, 30 ± 10.8 years) between 1/20/2006 and 1/20/2008. The genotype on the basis of hematologic and hemoglobin characteristics was hemoglobin SS in all patients. Pulmonary hypertension was prospectively defined as a tricuspid regurgitant Jet velocity (TFJV) of at least 2.5 m per second. Patients were followed for a mean of 18 months (6–24 months), and data were censored at the time of death or loss to follow-up. Doppler-defined pulmonary hypertension occurred in 37.5 percent of patients (30/80). Multiple logistic-regression analysis, with the use of the dichotomous variable of a tricuspid regurgitant jet velocity of less than 2.5 m per second or 2.5 m per second or more, identified age, female sex, deferasirox therapy, left ventricular mass index, pulmonary artery systolic pressure, reticulocytes, white-cell count, platelet count, lactate dehydrogenase (a marker of hemolysis), blood urea nitrogen, creatinine, uric acid and self-reported history of cardiovascular complication, billiary stones, retinopathy and acute chest syndrome, as significant independent correlates of pulmonary hypertension. The hemoglobin level, fetal hemoglobin level, hydroxyurea therapy and serum ferritin level were unrelated to pulmonary hypertension. Hazard rate for death according to the TFJV of at least 2.5 m per second, as compared with a velocity of less than 2.5 m per second, was associated with an increased risk of death (0.00 versus 2.54; P=0.998). Mortality rate in 24 months was 6.7% (2/30) for patients with TRJ velocity ≥ 2.5 m/sec versus 0.0% (0/50) for patients without pulmonary hypertension. Pulmonary hypertension, diagnosed by Doppler echocardiography, is common in adults with sickle cell disease. It appears to be a complication of chronic hemolysis, is resistant to hydroxyurea therapy, and confers a high risk of death. Large trials evaluating the effects of treatment for pulmonary hypertension in the sickle cell anemia population are indicated.

Abstract Background - Right heart catheterization (RHC) and echocardiography are both routinely used for pulmonary artery systolic pressure (PASP) assessment in lung transplantation (LT) candidates, although this is not mandated by current guidelines. We aimed to explore the correlation between PASP estimated by echocardiography to that measured by RHC, in this population in order to assess the necessity of RHC. Methods - From a retrospective registry of 393 LT candidates undergoing RHC and echocardiography during 2015-2019, patients were assessed for the presence of pulmonary hypertension (PH), defined as mean pulmonary artery pressure (mPAP) above 20 mmHg, according to two methods – echocardiography and RHC. The primary outcome was the correlation between the PASP estimated by echocardiography to that measured by RHC. Secondary outcomes were the prediction value of the echocardiographic evaluation and its accuracy. Results - The mean value of PASP estimated by echocardiography was 49.5±20.0 mmHg, compared to 42.5±18.0 mmHg measured by RHC. The correlation between the two measurements was moderate (Pearson’s correlation: r=0.609, p<0.01). Echocardiography PASP measurements were moderately discriminative to diagnose PH, with an area under the curve (AUC) of 0.72 (95% CI 0.66-0.76). Echocardiographic overestimation of PASP of more than 10 mmHg was found in 35.0% of the patients, and underestimation was found in 11.6% of the patients.Conclusion - In the pre-surgical evaluation of LT candidates, echocardiographic estimation of PASP had moderate correlation and limited accuracy compared to the PASP measured by RHC. We thus recommend performing routine RHC to all LT candidates, regardless of the echocardiographic estimation of PASP.

AbstractBackgroundPulmonary Arterial Hypertension (PAH) carries a poor prognosis in both adult and pediatric patients. It is a life-threatening condition in newborns. Current recommendations advocate the use of targeted monotherapy as a first-line approach for the treatment of Persistent Pulmonary Hypertension of the Newborn (PPHN). In case of an inadequate clinical response to treatment, an addition of a second or third agent is considered. PAH is usually managed with a phosphodiesterase 5 inhibitor or an endothelin receptor blocker. There are limited pediatric studies that address questions like which class of therapy should be initiated first or if a combination should be initiated together. With this background, the present study was initiated to compare the efficacy, safety, and tolerability of bosentan as an adjuvant to sildenafil and sildenafil alone in PPHN.ResultsA total of 40 patients were enrolled in the study. Out of them, 26 were males (65%) and 14 were females (35%). PPHN was most commonly seen in the 29 (72.5%) of participants with a history of first order birth. Mean duration of symptoms was 14.05 ± 2.06 days. The participants were randomized to two groups. Group A consisted of total 25 participants that received both bosentan and sildenafil and group B had 15 participants that received sildenafil alone. Both groups were comparable in terms of birth weight and present weight, consanguinity, and mode of delivery. Efficacy was determined by the reduction in mean baseline Pulmonary Artery Systolic Pressure (PASP). PASP in group A was 75.56 ± 10.62 mm Hg and in group B was 64.86 ± 12.25 mm Hg which was not statistically significant (P > 0.05). PASP on the third and seventh day in group A were 43.72 ± 8.63 and 24.47 ± 3.52 mm Hg compared to 42.28 ± 9.43 and 27.276 ± 8.38 respectively in group B which was statistically significant (P < 0.05).There were two deaths each in both groups. Two participants in Group A developed liver function abnormalities. None of the participants in Group B had adverse effects.ConclusionMost common clinical manifestations were nonspecific. Cardiovocal syndrome was common in PPHN. We conclude that oral sildenafil treatment is a safe, simple and effective treatment for persistent pulmonary hypertension in newborn. Combination of bosentan with sildenafil is more effective and safe in reducing pulmonary artery (PA) pressures in high-risk patients with PPHN.

Hyperthyroid Heart

Hyperthyroidism is a clinical state that results from increased thyroid hormone levels which has a significant impact on cardiac function and structure. Graves’ disease is the most common cause of hyperthyroidism in iodine-replete areas. Hyperthyroid heart disease may be associated with pulmonary hypertension in patients who have overt hyperthyroidism. To investigate the association of pulmonary hypertension induced by hyperthyroid heart disease and autoantibody, one hundred and one cases with hyperthyroid heart disease who were consecutively admitted to the inpatient department of endocrinology and metabolism of the Shandong Provincial Hospital between November 2014 and April 2018 were collected and analyzed statistically. According to the Independent samples T-test, variance analysis, chi-square test, Pearson linear correlation analysis, and logistic regression, there was a good correlation between pulmonary artery systolic pressure and thyroid stimulating hormone (TSH) and receptor antibodies (TRAb) (r = 0.264, P=0.025) (OR = 1.037, P=0.029), but there was no significant correlation between the pulmonary artery systolic pressure and other thyroid-related parameters (FT3, FT4, TSH, anti-TPO, and anti-TG). Based on variance analysis, PASP rose as the level of TRAb gets higher. What is more, patients with HHD combined with PH showed a significantly higher serum level of TRAb; moreover, serum TRAb concentration was remarkably correlated with the PASP level. Therefore, TRAb participates in the process of pulmonary hypertension caused by hyperthyroid heart disease.
