INTRODUCTION: Parenteral prostanoids are considered the treatment of choice for patients with severe pulmonary arterial hypertension (PAH). Prognostic studies for patients treated in the modern era are limited. METHODS: In this retrospective cohort study, patients initiating IV epoprostenol or IV or SC treprostinil therapy for PAH from 2007-2016 at UT Southwestern, Dallas, TX and Ohio State University, Columbus, OH were included. Transplant-free survival was assessed from the time of IV/SC initiation and from the time of first follow-up...

Tuberculosis (TB) is an infectious disease of global importance with major economic and social burden accounting for 25% of all avoidable deaths in developing countries. Extrapulmonary involvement may occur either in association with clinically apparent pulmonary tuberculosis or in isolation. This cross-sectional descriptive study aimed to evaluate the impact of ocular tuberculosis in visual acuity at baseline and after two months of intensive anti-tuberculous therapy. A sample of 133 pulmonary TB patients, seven disseminated TB, and three pleural TB patients was evaluated...

BACKGROUND: One-stage closure and fenestration are the available surgical options for bronchopleural fistula (BPF). One-stage closure may be applicable in cases with favorable infection control. Closing the bronchopleural stump is difficult due to thick adhesion caused by inflammation and a high risk of pulmonary artery injury. We report the successful closure of a BPF using a gastric seromuscular patch with an omental pedicle flap. CASE PRESENTATION: A 73-year-old man underwent right lower lobectomy with ND2a-2 lymph node dissection for lung adenocarcinoma...

AIM: Pulmonary thromboendarterectomy (PTE) is a recognized treatment for patients with chronic thromboembolic pulmonary hypertension (CTEPH), with good long-term haemodynamic results. The aim of this study was to test the hypothesis that the dynamics of health-related quality of life (QoL), 1 year after PTE, depends both on the clinical determinants associated with the underlying disease and the adverse events occurring in the early postoperative period. METHODS: This prospective cohort study included 136 patients with CTEPH...

BACKGROUND: The role of the intra-aortic balloon pump (IABP) in acute decompensated heart failure (HF) with cardiogenic shock (CS) is largely undefined. In this study we sought to assess the hemodynamic and clinical response to IABP in chronic HF patients with CS and identify predictors of response to this device. METHODS: We retrospectively reviewed all patients undergoing IABP implantation from 2011 to 2016 at our institution to identify chronic HF patients with acute decompensation and CS (cardiac index <2...

The functional significance of pulmonary arterial end-diastolic forward flow (EDFF) in patients with repaired tetralogy of Fallot (rTOF) is not fully understood, with conflicting reports regarding its associations with pulmonary regurgitation (PR), right ventricular (RV) size and function, and so-called restrictive RV physiology. To examine these associations, we retrospectively analyzed 399 patients with rTOF who had contemporaneous echocardiography (Echo) and cardiovascular magnetic resonance (CMR) studies...

Pulmonary hypertension is a serious condition with multiple underlying aetiologies which require different treatment strategies. We present a case of severe idiopathic pulmonary arterial hypertension in a 20-year-old patient with ongoing breathlessness. She was initially diagnosed with asthma and panic attacks in community care. As the symptoms became progressively worse, she was referred for pulmonary hypertension clinic assessment. Ventilation/perfusion single-photon emission computed tomography (V/Q SPECT) showed grossly abnormal perfusion defects which were mismatched to the ventilation scan, suggestive of chronic thromboembolic disease...

Despite the widespread acceptance of rotary blood pump (RBP) in clinical use over the past decades, the diminished flow pulsatility generated by a fixed speed RBP has been regarded as a potential factor that may lead to adverse events such as vasculature stiffening and hemorrhagic strokes. In this study, we investigate the feasibility of generating physiological pulse pressure in the pulmonary circulation by modulating the speed of a right ventricular assist device (RVAD) in a mock circulation loop. A rectangular pulse profile with predetermined pulse width has been implemented as the pump speed pattern with two different phase shifts (0% and 50%) with respect to the ventricular contraction...

INTRODUCTION: Pulmonary hypertension (PH) is characterized by enhanced pulmonary vascular resistance, which causes right ventricle (RV) pressure overload and results in right sided heart failure and death. This work investigated the effectiveness of a combined therapy with PDE5 inhibitor (PDE5i) and a new adenosine A2A receptor (A2AR) agonist in mitigating monocrotaline (MCT) induced PH in rats. METHODS: An in vitro isobolographic analysis was performed to identify possible synergistic relaxation effect between sildenafil and LASSBio 1359 in rat pulmonary arteries (PAs)...

Detrimental effects of air pollution with fine dust (particulate matter ≤2.5 μm in aerodynamic diameter, or PM2.5 ) on the systemic circulation and the left heart have been studied intensely during the past decade. In comparison, knowledge regarding the effects of exposure to air pollution with PM2.5 on the pulmonary vasculature and the right heart lags far behind. A report on severe lung disease and right heart failure in coal miners was published nearly 170 years ago. However, today, we still do not have a clear picture of how the effect of air pollution on the pulmonary circulation or the right heart should be viewed from a clinical, mechanistic biological, therapeutic, or economic angle...

RATIONALE: Smoking is a major risk factor for the development of cardiovascular and pulmonary diseases. The importance of the renin-angiotensin system in the development of cardiovascular and pulmonary disease is well established. Angiotensin-II, by means of its type 1 receptor (angiotensin type 1 receptor, AT1 R), promotes increased sympathetic activity, salt and water reabsorption, vasoconstriction, inflammation, and aldosterone and vasopressin release, contributing to tissue fibrosis, endothelium dysfunction, and hypertension...

Pulmonary arterial hypertension (PAH) is characterized by increased proliferation and resistance to apoptosis of pulmonary vascular cells. Increased expression of translationally controlled tumor protein (TCTP), a pro-survival and anti-apoptotic mediator, has recently been demonstrated in patients with hereditary PAH (HPAH) although its role in the pathobiology of PAH remains unclear. Silencing of TCTP in blood outgrowth endothelial cells (BOECs) isolated from control subjects led to significant changes in morphology, cytoskeletal organization, increased apoptosis and decreased directionality during migration...

BACKGROUND: In aortic valve stenosis (AS), congestive heart failure (CHF) is a well-established symptom that indicates the need for surgical aortic valve replacement (SAVR). However, it is difficult to judge whether CHF symptoms such as dyspnea are caused by severe AS or other conditions, especially in elderly persons with restricted mobility or other organ complications. It is important to identify objective and noninvasive parameters associated with severe CHF symptoms in severe AS...
