Pulmonary arterial smooth muscle cell (PASMC) migration plays a key role in vascular remodeling which occurs during development of chronic thromboembolic pulmonary hypertension (CTEPH). Activation of the renin-angiotensin system (RAS) contributes to vascular remodeling observed in many diseases including idiopathic pulmonary arterial hypertension. However, the role of RAS imbalance in CTEPH has not been characterized. Here, we hypothesize that RAS imbalance regulates vascular remodeling by promoting PASMC migration in CTEPH...

BACKGROUND: Balloon pulmonary angioplasty (BPA) is an alternative therapy for patients with chronic thromboembolic pulmonary hypertension who are ineligible for pulmonary endarterectomy-the standard therapy. Currently, most reported results of BPA are from relatively small cohorts treated at single centers. The present study evaluated the safety and efficacy of BPA for chronic thromboembolic pulmonary hypertension based on a multicenter registry. METHODS AND RESULTS: A total of 308 patients (62 men and 246 women; mean age, 61 years) underwent 1408 procedures at 7 institutions in Japan...

OBJECTIVES: Pulmonary artery sarcoma (PAS) is a rare and devastating disease. The diagnosis modality and optimal surgical strategy remain unclear. The aim of this study was to report our surgical experience in this disease. METHODS: Between 2000 and 2017, 13 patients underwent operations for PAS at our institution. Five patients underwent tumour resection alone, whereas the other 8 patients received pulmonary endarterectomy. The medical records were retrospectively reviewed to evaluate the clinical characteristics, operative findings and the postoperative outcomes...

OBJECTIVES: Pulmonary endarterectomy (PEA) is the only curative treatment option for patients with chronic thromboembolic pulmonary hypertension. Massive endobronchial bleeding that precludes weaning from cardiopulmonary bypass is an often-fatal complication of PEA. The aim of this study was to determine whether short-term extracorporeal membrane oxygenation (ECMO) is a safe and feasible procedure in patients with severe endobronchial bleeding. METHODS: From January 2014 to December 2016, 396 patients (mean age 60 ± 18 years, 54...

Chronic thromboembolic pulmonary hypertension (CTEPH) is an underdiagnosed potential complication of acute or recurrent pulmonary thromboembolic disease. Multiple studies suggest that up to 5% of patients with acute pulmonary thromboembolic disease go on to develop CTEPH. The prognosis of untreated CTEPH is poor, but advances in medical and surgical treatments over the past few decades have improved patient outcomes. The gold standard and curative treatment for CTEPH is pulmonary endarterectomy; however, some patients are inoperable and others who have undergone pulmonary endarterectomy experience persistent or recurrent pulmonary hypertension despite medical therapy...

- Chronic thromboembolic pulmonary hypertension (CTEPH), characterised by pulmonary hypertension and persistent perfusion defects despite adequate anticoagulation, causes significant morbidity and mortality.- Persistent dyspnoea after acute pulmonary embolism is frequent and an indication for additional diagnostics. Only a minority of these patients develop CTEPH.- Echocardiography and perfusion scintigraphy are the cornerstone of diagnostics when suspecting CTEPH. Right-heart catheterisation and pulmonary angiography should confirm the diagnosis...

Pulmonary artery (PA) catheters are routinely used for hemodynamic management in patients with chronic thromboembolic pulmonary hypertension (CTEPH) undergoing pulmonary endarterectomy (PEA). Tip-associated thrombi are frequently detected and might increase the peri-operative risk in these patients. The aim of the study was to investigate the effects of low-dose heparinization before the insertion of the PA catheter on thrombus formation and thrombus weight during PEA surgery. From September 2013 to February 2015, 60 CTEPH patients undergoing PEA were included in the study and randomized into two groups of 30 patients each, including a heparin group (heparin bolus (70 IU per kg body weight) administration before PA catheter insertion) and a control group (pretreatment with placebo)...

BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is still largely underdiagnosed in the general population. Although transthoracic echocardiogram (TTE) is recommended to screen for CTEPH, it may not detect patients with chronic thromboembolic disease (CTED) and mild or exercise-induced pulmonary hypertension (PH) who could also benefit from pulmonary endarterectomy (PEA). METHODS: All patients referred to our CTEPH program with persistent mismatched perfusion defects on ventilation-perfusion (VQ) scan between January 2005 and June 2015 were divided into three groups according to TTE and right heart catheterization (RHC) as follows: (1) typical CTEPH group (PH on RHC and TTE), (2) TTE-negative (neg) CTEPH group (PH on RHC, but not TTE), or (3) CTED group (no PH on RHC and TTE)...

INTRODUCTION: Pulmonary endarterectomy (PEA) is the most effective treatment available for chronic thromboembolic pulmonary hypertension (CTEPH). Patient selection, surgical technique and perioperative management have improved patient outcomes, which are traditionally linked to surgical and center experience. However, optimal perfusion care has not been well defined. The goal of the international survey was to better characterize the contemporary perfusion management of PEA and highlight similarities and controversies...

Both pharmacological and invasive treatment of chronic thromboembolic pulmonary hypertension (CTEPH) is now available in Poland and the awareness of the disease among physicians is growing. Thus, the Polish Cardiac Society's Working Group on Pulmonary Circulation in cooperation with independent experts in this field, have launched the statement on algorithm to guide a CTEPH diagnosis in patients with previous acute pulmonary embolism (APE). In Poland, every year this disease affects about 250 patients. CTEPH should be suspected in individuals after APE with dyspnea, despite at least 3 months period of effective anticoagulation, particularly when specified risk factors are present...

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare clinical entity that occurs in a small subset of acute pulmonary embolism (PE) cases and is surgically cured by pulmonary endarterectomy. We report a case of a 44-year-old female with a complex history of CTEPH treated by thromboendarterectomy who presented with a subdural hematoma while on warfarin. The patient eventually recovered by a multidisciplinary approach, use of inferior vena caval filter, and effective anticoagulation management.

Despite advances in treatments and improved survival, patients with pulmonary hypertension still experience poor exercise and functional capacity, which has a significant detrimental impact on their quality of life. The nitric oxide (NO)-soluble guanylate cyclase (sGC)-cyclic guanosine 3',5'-monophosphate (cGMP) pathway has been shown to play an important role in cardiovascular physiology, especially in vasodilation and pulmonary vascular tone. The oral sGC stimulator riociguat has a dual mode of action on the NO-sGC-cGMP pathway: direct stimulation of sGC independent of NO and indirect simulation via sensitization of sGC to endogenous NO...
