Abstract
Pulmonary hypertension (PH) presents as a complex hemodynamic and pathophysiologic state present in many cardiovascular, respiratory, and systemic diseases. PH is considered to have a higher risk of cardiovascular events and mortality. The most common type of functional tricuspid regurgitation (TR) is associated with PH. Secondary TR, resulting not from intrinsic valvular pathology but from distortion of the valve apparatus due to right ventricular remodeling and dilation, is commonly seen in the setting of PH. It has been increasingly recognized as not merely a bystander but a significant contributor to the worsening of symptoms and decline in functional status. However, the extent to which TR impacts the clinical course and mortality in PH remains a subject of active investigation. The simultaneous presence of PH and secondary tricuspid regurgitation (STR) portends particularly poor outcomes. However, not all patients with PH develop significant TR, and the mechanisms and clinical implications underlying this phenomenon remain unclear. TR is a highly prevalent echocardiographic finding in the general population. Historically considered as the "forgotten valve disease" by clinicians and interventional cardiologists, TR has become a hot topic in cardiovascular interventions over recent years. If left untreated until severe, as often occurs, TR correlates with consistent morbidity and mortality, and a variety of surgical and percutaneous treatments have therefore been proposed. Mortality from isolated surgical repair of TR remains higher than that from surgery of any other valve insufficiency and a large number of patients are often deemed not eligible for surgical repair.

Effects of right ventricular remodeling in chronic thromboembolic pulmonary hypertension on the outcomes of balloon pulmonary angioplasty: a 2D-speckle tracking echocardiography study. Respir Res 2024; 25:164. [PMID: 38622598 PMCID: PMC11020924 DOI: 10.1186/s12931-024-02803-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 04/03/2024] [Indexed: 04/17/2024] Open
Abstract
BACKGROUND Balloon pulmonary angioplasty (BPA) improves the prognosis of chronic thromboembolic pulmonary hypertension (CTEPH). Right ventricle (RV) is an important predictor of prognosis in CTEPH patients. 2D-speckle tracking echocardiography (2D-STE) can evaluate RV function. This study aimed to evaluate the effectiveness of BPA in CTEPH patients and to assess the value of 2D-STE in predicting outcomes of BPA. METHODS A total of 76 patients with CTEPH underwent 354 BPA sessions from January 2017 to October 2022. Responders were defined as those with mean pulmonary artery pressure (mPAP) ≤ 30 mmHg or those showing ≥ 30% decrease in pulmonary vascular resistance (PVR) after the last BPA session, compared to baseline. Logistic regression analysis was performed to identify predictors of BPA efficacy. RESULTS BPA resulted in a significant decrease in mPAP (from 50.8 ± 10.4 mmHg to 35.5 ± 11.9 mmHg, p < 0.001), PVR (from 888.7 ± 363.5 dyn·s·cm-5 to 545.5 ± 383.8 dyn·s·cm-5, p < 0.001), and eccentricity index (from 1.3 to 1.1, p < 0.001), and a significant increase in RV free wall longitudinal strain (RVFWLS: from 15.7% to 21.0%, p < 0.001). Significant improvement was also observed in the 6-min walking distance (from 385.5 m to 454.5 m, p < 0.001). After adjusting for confounders, multivariate analysis showed that RVFWLS was the only independent predictor of BPA efficacy. The optimal RVFWLS cutoff value for predicting BPA responders was 12%. CONCLUSIONS BPA was found to reduce pulmonary artery pressure, reverse RV remodeling, and improve exercise capacity. RVFWLS obtained by 2D-STE was an independent predictor of BPA outcomes. Our study may provide a meaningful reference for interventional therapy of CTEPH.

Abstract
Right heart catheterization (RHC) represents the gold standard diagnostic approach for pulmonary hypertension (PH). Historically, the complication rates of RHC are known to be low. The study aimed to evaluate the indications for performing RHC and the occurrence of adverse events related to the procedure in patients > over 70 years of age in a Mexican Tertiary Care Center. We conducted a retrospective single-center registry from July 2017 to July 2022. A total of 517 patients with suspected PH underwent RHC. The cohort included patients <70 (n = 427) and ≥70 years of age (n = 90). Adverse events were classified as major (eg, death, pneumothorax, and carotid artery puncture) and minor (eg, atrial arrhythmia, superior vena cava dissection, incidental arterial puncture, and local hematoma). Appropriate hemodynamic parameters were recorded. No report of major adverse events in the entire cohort. In the <70 years age group, 9 minor events, and 3 minor events were in the ≥70-year-old patients (P < 0.0001). There was a significant difference in the measurement of mean pulmonary artery pressure (mPAP) between the <70 years old vs ≥70 years old (P < 0.001); there was a significant difference in right atrial pressures: 4.71 ± 3.14 mmHg in the <70-year-old vs 4.07 ± 1.94 mmHg for the ≥ 70-year-old group (P = 0.014). Our findings suggest that RHC can be safely performed in patients aged ≥70 years using different vascular access routes without significant major complications.

Abstract
Currently, several imaging techniques are being used for a comprehensive evaluation of patients with suspected pulmonary hypertension (PH), in order to provide information that may clarify the presence and identify the aetiology of this complex pathology. The current paper is focused on recent updates regarding the importance of comprehensive imaging techniques for patients with suspected PH. Transthoracic echocardiography that can mainly detect right ventricle pressure overload and dysfunction is the cornerstone of imaging evaluation, while right heart catheterisation remains the gold standard assessment method. Chest radiography that may exclude pleuroparenchymal lung diseases, CT, the primary imaging modality for the assessment of lung parenchyma and CT pulmonary angiography, that allows for the non-invasive assessment of the pulmonary arteries, are equally important. Imaging techniques like dual-energy CT, single photon emission CT and ventilation perfusion scan may provide accurate diagnostic information for patients with chronic thromboembolic PH. Cardiac MRI provides the most accurate three-dimensional characterisation of the right ventricle. Accurate use of diagnostic imaging algorithms allows early detection of the disease, with the constant goal of improved PH patients prognosis.

Abstract
Hypothyroidism has been shown to have several effects on organs, including derangements in the coagulation system, impairing endothelial function, but data on the importance of hypothyroidism in the pathogenesis and development of chronic thromboembolic pulmonary hypertension (CTEPH) are limited. This report presents an updated review of the prevalence and prognosis of hypothyroidism in patients diagnosed with CTEPH, including a detailed retrospective description of the series. The descriptive case series included 34 adult patients diagnosed with CTEPH, of whom 11 patients were diagnosed with hypothyroidism. The prevalence of hypothyroidism in CTEPH was found to be 32.35%. All patients with hypothyroidism had NYHA functional Class II-III. Hemodynamic values obtained through right heart catheterization (RHC) showed that patients with hypothyroidism had significantly higher mean pulmonary arterial pressures (mPAP), with a mean of 56.91 mm Hg vs 43.93 mm Hg (p = 0.026), and the PVR in dynes/sec/cm5 was 932 vs 541 (p = 0.027). Significant differences in PVR were found in wood units (WU) 11.91 vs 7.11 (p = 0.042). The mean level of brain natriuretic peptide (BNP) between both groups was 797.3 pg/mL for patients with hypothyroidism vs 262.02 pg/mL in patients with euthyroidism (p = .032). Hypothyroidism may significantly affect patients' clinical and hemodynamic outcomes in patients with CTEPH. Hypothyroidism as a risk factor in the evaluation and treatment of these patients is vital to optimize outcomes in CTEPH; further research is warranted whether hypothyroidism therapies could alter such outcomes.

Curr Vasc Pharmacol 2024; 22:67-77. [PMID: 38038005 DOI: 10.2174/0115701611268078231010072521] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 09/24/2023] [Accepted: 10/02/2023] [Indexed: 12/02/2023]
Abstract
BACKGROUND Pulmonary arterial hypertension (PAH) still lacks effective biomarkers to assist in its diagnosis and prognosis. Galectin-3 binding protein (Gal-3BP) plays a role in immune and inflammatory diseases. OBJECTIVE This study aimed to evaluate Gal-3BP as a prognostic and predictive factor in patients with PAH. METHODS From January 2017 to December 2019, we enrolled 167 consecutive PAH patients and 58 healthy controls. Right heart catheterization (RHC) was used to diagnose PAH. Serum Gal-3BP levels were measured by high-sensitivity human enzyme-linked immunosorbent assay (ELISA). RESULTS Serum Gal-3BP levels in the PAH group were significantly higher compared with the control group (4.87±2.09 vs 2.22±0.86 μg/mL, p<0.001). Gal-3BP level was correlated with several hemodynamic parameters obtained from RHC (p<0.001). Multivariate linear regression analysis showed that Gal-3BP was a risk factor for PAH (odds ratio (OR)=2.947, 95% CI: 1.821-4.767, p<0.001). The optimal cut-off value of serum Gal-3BP level for predicting PAH was 2.89 μg/mL (area under the curve (AUC)=0.860, 95 % CI: 0.811-0.910, p<0.001). Kaplan-Meier analysis showed that Gal-3BP levels above the median (4.87 μg/mL) were associated with an increased risk of death in patients with PAH (hazard ratio (HR)=8.868, 95 % CI: 3.631-21.65, p<0.0001). Cox multivariate risk regression analysis showed that Gal-3BP was a risk factor for death in PAH patients (HR=2.779, 95 % CI: 1.823-4.237, p<0.001). CONCLUSION Serum Gal-3BP levels were increased in patients with PAH, and levels of Gal-3BP were associated with the severity of PAH. Gal-3BP might have predictive value for the diagnosis and prognosis of PAH.

Abstract
AIMS To evaluate BM-MSCs and their extracellular vesicles (EVs) preconditioned with hypoxia or normoxia in experimental pulmonary arterial hypertension (PAH). MAIN METHODS BM-MSCs were isolated and cultured under normoxia (MSC-N, 21%O2) or hypoxia (MSC-H, 1%O2) for 48 h. EVs were then isolated from MSCs under normoxia (EV-N) or hypoxia (EV-H). PAH was induced in male Wistar rats (n = 35) with monocrotaline (60 mg/kg); control animals (CTRL, n = 7) were treated with saline. On day 14, PAH animals received MSCs or EVs under normoxia or hypoxia, intravenously (n = 7/group). On day 28, right ventricular systolic pressure (RVSP), pulmonary acceleration time (PAT)/pulmonary ejection time (PET), and right ventricular hypertrophy (RVH) index were evaluated. Perivascular collagen content, vascular wall thickness, and endothelium-mesenchymal transition were analyzed. KEY FINDINGS PAT/PET was lower in the PAH group (0.26 ± 0.02, P < 0.001) than in CTRLs (0.43 ± 0.02) and only increased in the EV-H group (0.33 ± 0.03, P = 0.014). MSC-N (32 ± 6 mmHg, P = 0.036), MSC-H (31 ± 3 mmHg, P = 0.019), EV-N (27 ± 4 mmHg, P < 0.001), and EV-H (26 ± 5 mmHg, P < 0.001) reduced RVSP compared with the PAH group (39 ± 4 mmHg). RVH was higher in the PAH group than in CTRL and reduced after all therapies. All therapies decreased perivascular collagen fiber content, vascular wall thickness, and the expression of endothelial markers remained unaltered; only MSC-H and EV-H decreased expression of mesenchymal markers in pulmonary arterioles. SIGNIFICANCE MSCs and EVs, under normoxia or hypoxia, reduced right ventricular hypertrophy, perivascular collagen, and vessel wall thickness. Under hypoxia, MSCs and EVs were more effective at improving endothelial to mesenchymal transition in experimental PAH.

Association Between the Degree of Severity of Pulmonary Hypertension With the Presence of Pulmonary Artery Aneurysm: A Brief Updated Review for Clinicians. Curr Probl Cardiol 2023; 48:101645.

Abstract
Pulmonary hypertension (PH) is defined as an increase in mean pulmonary arterial pressure (mPAP) ≥20 mm Hg at rest as assessed by right cardiac catheterization. It has a median survival nowadays of 6 years, compared to 2.8 years in the 1980s. A pulmonary artery aneurysm (PAA) is the focal dilation of a blood vessel involving all 3 layers of the vessel wall; they have a diameter greater than 4 cm measured in the trunk of the pulmonary artery. PAAs can be classified into proximal (or central) and peripheral. The clinical manifestations of PAA are primarily nonspecific, and most patients remain undiagnosed, even those with large PAA, due to its silent course; however, clinical manifestations occur unless when there are complications such as bronchial or tracheal compression (leading to cough and dyspnea), dissection, or rupture (leading to hemoptysis). PAH is observed in 66% of patients with PAA. PA dissections are usually associated with PAH; 80% of dissections occur in the main pulmonary trunk. Although there is no clear guideline for the best treatment of PAA, surgery is indicated in patients with a pulmonary trunk aneurysm >5.5 cm. It has been observed that patients in the PAH group associated with congenital heart disease tend to develop PAA more commonly. Those with PAH associated with connective tissue disease have a smaller diameter of PA dilation. This report presents a comprehensive review of PAA, discussing critical aspects of the clinical and imaging diagnosis, hemodynamics, and treatment. A comprehensive updated literature review is included; we believe this article will interest cardiopulmonologists.

Abstract
Idiopathic pleuroparenchymal fibroelastosis (iPPFE) is a little-known entity with unique clinical, radiological, and pathological features. iPPFE is chronic interstitial pneumonia characterized by the thickening of elastic fibers in the pleura and subpleural parenchyma involving the upper lobes. Computed tomography pulmonary angiography (CTPA) usually depicts bilateral pleural thickening, with a left scalloped appearance that conditions retraction of the structures of the superior mediastinum and both pulmonary hila, associated with pulmonary consolidations with bronchogram air and thickening of the peribronchovascular interstitium, in addition to areas of left apical air trapping. When severe enough, the disease leads to progressive loss of volume of the upper lobes, decreased body mass, and platythorax. Some patients with iPPFE follow an inexorably progressive course culminating in irreversible respiratory failure and premature death. Up to 20% of patients might develop pulmonary hypertension (PH); transthoracic echocardiography is used as a screening test for PH; right heart catheterization performed in a tertiary-care hospital will confirm the diagnosis. Because iPPFE can be easily confused and misdiagnosed with infectious pathologies, such as pulmonary tuberculosis, and easily confuse physicians with little expertise in diffuse interstitial lung diseases, knowing the differential diagnoses, clinical presentation, imaging, and complications of the iPPFE allows for an early diagnosis and gives patients who suffer from it a better quality of life. This report presents a comprehensive review of PPFEi, discussing severe precapillary pulmonary hypertension and the associated findings demonstrated by right heart catheterization (RHC), which be of interest for cardiopulmonologists.
