According to recent studies, lung uptake of iodine-123-metaiodobenzylguanidine (123I-MIBG) is impaired in many lung diseases and low lung uptake of 123I-MIBG suggests endothelial dysfunction of the pulmonary artery. 123I-MIBG scintigraphy in patients with pulmonary hypertension (PH) has not yet been clinically evaluated. We hypothesized that the lung uptake of 123I-MIBG is reduced in patients with PH and differs among PH subtypes. The purpose of the present study was to analyze the lung uptake of 123I-MIBG in patients with PH and compare it with the data obtained by echocardiography or right heart catheterization...

Pulmonary arterial hypertension (PAH) is a rare disorder that can be drug-induced, mostly following treatment by appetite-suppressant drugs. We report four cases of patients who developed PAH following a treatment by leflunomide for rheumatoid arthritis, psoriatic arthritis or undetermined connective tissue disease. All patients described a progressive dyspnea from grade II to IV of NYHA classification; clinical examination found signs of heart failure. PAH was finally diagnosed and confirmed by right heart catheterisation...

BACKGROUND: Balloon pulmonary angioplasty (BPA) is an emerging interventional treatment option for chronic thromboembolic pulmonary hypertension (CTEPH). The non-invasive monitoring of CTEPH patients is a clinical challenge. In this study we examined changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients undergoing BPA for inoperable CTEPH and related them to peri-procedural success. METHODS: In this study we analyzed a total of 51 consecutive patients who underwent BPA treatment and completed a 6-month follow-up (6-MFU) between March 2014 and March 2017...

Antiphospholipid syndrome (APS) is a cause of chronic thromboembolic pulmonary hypertension (CTEPH) and it is associated with an increased risk of postoperative neurological complications. We experienced a case of reversible parkinsonism after pulmonary endarterectomy (PEA) and subsequent multiple cerebral infarctions under standard anticoagulation therapy in a patient with CTEPH associated with APS. Strict management using a combination of antiplatelet and anticoagulation therapy should be considered in patients with a high titer of triple antiphospholipid antibodies in the perioperative period...

Extrinsic compression of the left main coronary artery (LMCA) can occur in patients with an enlarged pulmonary artery trunk secondary to severe pulmonary hypertension (PH). This phenomenon rarely occurs in PH; moreover, few reports have shown that chronic thromboembolic PH can be a triggering factor for this syndrome. Herein, we describe a patient with extrinsic compression of the LMCA with chronic thromboembolic PH who underwent pulmonary endarterectomy and coronary artery bypass grafting successfully. Intravenous ultrasonography (IVUS) was effective for detecting and assessing the compression...

Pulmonary hypertension (PH) is a relatively frequent and severe complication of sickle cell disease (SCD). PH associated with SCD is classified as Group 5 PH. The exact pathogenesis of PH in SCD in not known. There are also very limited treatment options available at this time for such patients with Group 5 PH. Patients with SCD are predisposed to a hypercoagulable state and thus can also suffer from chronic thromboembolism. These patients can have associated chronic thromboembolic pulmonary hypertension (CTEPH), thus being classified as Group 4 PH...

BACKGROUND: The treatment of choice for chronic thromboembolic pulmonary hypertension (CTEPH) is pulmonary endarterectomy (PEA). However, not all patients are eligible for PEA, and some patients experience recurrence of pulmonary hypertension even after PEA. METHODS: Patients who underwent balloon pulmonary angioplasty (BPA) between December 2015 and April 2017 were enrolled from the Samsung Medical Center CTEPH registry. Enrolled patients underwent right heart catheterization, echocardiography, and 6-minute walk distance (6MWD) at baseline, 4 and 24 weeks after their first BPA session...

Patients with non-transfusion-dependent thalassemia (NTDT) experience many clinical complications despite their independence from frequent transfusions. Morbidities in NTDT stem from the interaction of multiple pathophysiological factors: ineffective erythropoiesis, iron overload (IOL), and hypercoagulability. Ineffective erythropoiesis and hemolysis are associated with chronic hypoxia and a hypercoagulable state. The latter are linked to a high prevalence of thromboembolic and cerebrovascular events, as well as leg ulcers and pulmonary hypertension...

Since 1998 pulmonary hypertension has been clinically classified into five well-defined, distinct categories. A definitive diagnosis of pulmonary hypertension requires the invasive confirmation of an elevated mean pulmonary artery pressure of 25 mm Hg or above during a right heart catheterization. From a hemodynamic point of view, pulmonary hypertension is classified into precapillary and postcapillary pulmonary hypertension on the basis of a pulmonary artery wedge pressure threshold value of 15 mm Hg. Pulmonary vascular resistance is better characterized by multi-point pressure/flow measurements than by single-point determination...

A previously healthy 2-year-old Guatemalan female with an undiagnosed chronic illness characterized by fever and rash had presented with anorexia, weight loss, periorbital edema, abdominal pain and distention. A chest radiograph documented cardiomegaly. An echocardiogram demonstrated a pericardial effusion, dilated right atrium, right ventricle, and main pulmonary artery as well as diminished right ventricular systolic function and pulmonary hypertension. Right ventricular systolic pressure was estimated at 90 mmHg...

Clinical classification of pulmonary hypertension (PH) includes five groups: pulmonary arterial hypertension (PAH), PH due to left heart disease, PH due to lung diseases and/or hypoxemia, chronic thromboembolic PH, and PH with unclear and/or multifactorial mechanism. PH is categorized according to clinical presentation, pathological findings, hemodynamic significances and treatment strategy. The authors report a case of reversible PH with unknown etiology in association with suspected acute viral illness.

OBJECTIVES: Left ventricular dysfunction after pulmonary endarterectomy is well described. Left ventricular failure has only been described after lung transplantation for pulmonary arterial hypertension (PAH). We sought to identify factors that contribute to this failure and hypothesized that atrial septostomy before transplantation could prevent this complication. METHODS: From our database, all bilateral lung transplants for PAH (n = 24) and all pulmonary endarterectomies, with a minimal reduction of 800 dyn⋅s⋅cm-5 (n = 27), were selected...

Chronic thromboembolic pulmonary hypertension (CTEPH) has a poor prognosis because of the associated progressive right heart failure. Accurate evaluation of right ventricular (RV) function would thus be useful to predict prognosis. However, the significance of RV diastolic function remains unclear. We aimed to identify which echocardiographic measures are most accurate, and potentially useful, in assessing RV diastolic function in patients with CTEPH, and to study the effects of balloon pulmonary angioplasty (BPA) on them...

BACKGROUND: Pulmonary thromboendarterectomy (PTE) is an effective treatment for chronic thromboembolic pulmonary hypertension (CTEPH), but is a technically challenging operation for cardiothoracic surgeons. Starting a new program allows an opportunity to define a learning curve for PTE. METHODS: A retrospective case review was performed of 134 consecutive PTEs performed from 1998 to 2016 at a single institution. Outcomes were compared using either a two-tailed t-test for continuous variables or a chi-squared test for categorical variables according to experience of the program by terciles (T)...

BACKGROUND: Following positive results from the Phase III CHEST-1 study in patients with inoperable or persistent/recurrent chronic thromboembolic pulmonary hypertension (CTEPH), the Phase IIIb CTEPH early access study (EAS) was designed to assess the safety and tolerability of riociguat in real-world clinical practice, as well as to provide patients with early access to riociguat before launch. Riociguat is approved for the treatment of inoperable and persistent/recurrent CTEPH. METHODS: We performed an open-label, uncontrolled, single-arm, early access study in which 300 adult patients with inoperable or persistent/recurrent CTEPH received riociguat adjusted from 1 mg three times daily (tid) to a maximum of 2...

Electrocardiography (ECG) is used to screen for pulmonary hypertension (PH). However, it is unclear which parameters of ECG are the most useful for screening.ECG parameters related to right ventricular hypertrophy criteria were examined in 145 ECGs of subjects who were suspected to have PH and underwent right heart catheterization (RHC) (age 58.4 ± 17.5 years, 112 women, mean pulmonary arterial pressure [MPAP] 35.4 ± 13.3 mmHg). Based on the results of RHC, 108 subjects had PH (56 pulmonary arterial hypertension [PAH] and 52 chronic thromboembolic pulmonary hypertension [CTEPH])...

INTRODUCTION: The 6-min walk test (6MWT) is commonly performed to assess functional status in patients with chronic thromboembolic pulmonary hypertension. However, changes in heart rate and oxygen saturation (SpO2 ) patterns during 6MWT in patients with chronic thromboembolic pulmonary hypertension remain unclear. METHODS: Thirty-one subjects with chronic thromboembolic pulmonary hypertension were retrospectively evaluated to examine the relationships between the change in heart rate (Δheart rate), heart rate acceleration time, slope of heart rate acceleration, heart rate recovery during the first minute after 6MWT (HRR1), change in SpO2 (ΔSpO2 ), SpO2 reduction time, and SpO2 recovery time during 6MWT, and the severity of pulmonary hemodynamics assessed by right heart catheterization and echocardiography...

OBJECTIVES: Balloon pulmonary angioplasty (BPA) in patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH) can have variable outcomes. To gain more insight into this variation, we designed a method for visualizing and quantifying changes in pulmonary perfusion by automatically comparing computed tomography (CT) pulmonary angiography before and after BPA treatment. We validated these quantifications of perfusion changes against hemodynamic changes measured with right-sided heart catheterization...

AIM: Balloon pulmonary angioplasty (BPA) has recently been established as an effective therapy for peripheral-type chronic thromboembolic pulmonary hypertension (CTEPH). However, the safety and effectiveness of BPA in elderly patients with CTEPH have not been clarified. METHODS: A total of 19 patients with CTEPH who underwent BPA were recruited. The patients were assigned to groups by age, <70 years (non-elderly; n = 11) and ≥70 years (elderly; n = 8). Hemodynamic parameters, right ventricular function and plasma N-terminal pro-brain natriuretic peptide were assessed before and after BPA, and complications arising after BPA were also evaluated...
