Feasibility of revascularization after gelatin sponge embolization for hemoptysis during balloon pulmonary angioplasty. Int J Cardiol 2024; 413:132343. [PMID: 38977227 DOI: 10.1016/j.ijcard.2024.132343] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Revised: 06/16/2024] [Accepted: 07/05/2024] [Indexed: 07/10/2024]
Abstract
BACKGROUND Vessel injury is a common complication during balloon pulmonary angioplasty (BPA). For persistent hemoptysis, gelatin sponge embolization (GSE) is considered, but its impact on subsequent perfusion in embolized vessels remains unknown. This study explores the feasibility of revascularization in vessels post-GSE. METHODS We included 64 vessels from 50 patients with chronic thromboembolic pulmonary hypertension who experienced hemoptysis during BPA in 2012-2023. Twenty-four vessels were treated conservatively (conservative group), while 40 were treated with GSE for persistent hemoptysis or desaturation despite conservative treatment (GSE group). We assessed hemoptysis-related parameters, perfusion of injured vessels pre- and post-treatment, and hemodynamic parameters through multiple BPA sessions. RESULTS Hemoptysis resolved immediately after the procedure in 67% of patients, including 70% of those in the GSE group, and all cases resolved by the next day. Of 37 embolized vessels, 41% showed spontaneous perfusion improvement in subsequent sessions. BPA was reperformed in 22 embolized vessels, with 86% showing further improvement, resulting in 70% of all embolized vessels finally showing improvement in perfusion. In both groups, clinical and hemodynamic parameters significantly improved after BPA. CONCLUSIONS Perfusion of embolized vessels improved after GSE, suggesting that GSE is safe for the treatment of severe persistent hemoptysis after conservative treatment.

Balloon pulmonary angioplasty for proximal chronic thromboembolic pulmonary hypertension in patients ineligible for pulmonary endarterectomy. Pulm Circ 2024; 14:e12432.

Abstract
Balloon pulmonary angioplasty (BPA) to treat chronic thromboembolic pulmonary hypertension (CTEPH) is generally reserved for distal obstruction precluding pulmonary endarterectomy (PEA) but can be used in patients with proximal disease who are at high surgical risk or refuse surgery. This single-center retrospective study compared BPA efficacy in patients with proximal versus distal CTEPH. Of the 478 patients, 36 had proximal disease, follow-up was 11.6 months and mean number of BPA 6. After BPA, PVR, and mean pulmonary artery pressure decreased significantly in the proximal and distal groups (from 6.5 to 4.0 WU and 39 to 31 mmHg and from 7.6 to 3.8 WU and 44 to 31 mmHg, respectively, p < 0.001 for all comparisons). NYHA class also improved significantly in both groups, from 3 to 2, whereas the 6-min walk distance, cardiac output, and serum NT pro-BNP showed significant improvements only in the distal group. Thus, when PEA for CTEPH is technically feasible but not performed due to severe comorbidities or patient refusal, BPA can produce significant hemodynamic improvements, albeit less marked than in patients with distal disease. Better patient selection to BPA might improve outcomes in patients with proximal disease who are ineligible for PEA.

Abstract
Natural hemodynamic changes after balloon pulmonary artery angioplasty (BPA) in a unified state without oxygen administration in patients with chronic thromboembolic pulmonary hypertension (CTEPH) remains undetermined. This study aimed to clarify the delayed changes in the hemodynamics after BPA in patients with CTEPH. We analyzed 73 consecutive patients with CTEPH who underwent BPA between July 2014 and December 2022. We extracted and evaluated hemodynamic data of the right heart catheter without oxygen administration immediately before and after the first BPA; and immediately before the second BPA, as the "post-delayed changes" after BPA. BPA significantly improved the mean pulmonary artery pressure (mPAP, mmHg) and pulmonary vascular resistance (PVR, dyn-s/cm5) from 36 (32-43) mmHg and 449 (312-627) dyn-s/cm5 before the first BPA to 28 (23-32) mmHg and 275 (217-366) dyn-s/cm5 immediately after BPA, and further significantly improved the values to 23 (20-28) mmHg and 225 (175-301) dyn-s/cm5 post-delayed changes after BPA, respectively. Improvement observed on account of delayed changes was observed both with and without pulmonary hypertension drugs. The delayed changes were observed during a period of 5-180 days, which did not correlate with the changes in mPAP and PVR. Hemodynamic improvement owing to BPA was observed immediately after BPA; however, further improvement was observed as a result of delayed changes. mPAP improved by 3.4 ± 5.2 mmHg and PVR by 53 (10-99) dyn-s/cm5 as delayed improvement. mPAP and PVR showed delayed improved by approximately 10% of their values before BPA.

Abstract
Balloon pulmonary angioplasty (BPA) has recently been elevated as a class I recommendation for the treatment of inoperable or residual chronic thromboembolic pulmonary hypertension (CTEPH). Proper patient selection, procedural safety, and post-procedural evaluation are crucial in the management of these patients, with imaging work-up playing a pivotal role. Understanding the diagnostic and therapeutic imaging algorithms of CTEPH, the imaging features of patients amenable to BPA, all imaging findings observed during and immediately after the procedure and the changes observed during the follow-up is crucial for all interventional radiologists involved in the care of patients with CTEPH. This article illustrates the imaging work-up of patients with CTEPH amenable to BPA, the imaging findings observed before, during and after BPA, and provides a detailed description of all imaging modalities available for CTEPH evaluation.

Abstract
BACKGROUND Balloon pulmonary angioplasty improves the hemodynamics of patients with inoperable chronic thromboembolic pulmonary hypertension; however, the clinical impact of recurrent pulmonary hypertension after balloon pulmonary angioplasty remains unclear. METHODS We retrospectively reviewed 262 consecutive patients with chronic thromboembolic pulmonary hypertension who underwent balloon pulmonary angioplasty between July 2009 and December 2020; 158 (65 ± 12 years; males, 20%; median follow-up period, 45 [26, 66] months) with follow-up right heart catheterization and no residual pulmonary hypertension were included. Recurrent pulmonary hypertension was defined as mean pulmonary arterial pressure <25 mm Hg at the first evaluation after balloon pulmonary angioplasty and ≥25 mm Hg at follow-up evaluation requiring additional treatment with balloon pulmonary angioplasty or pulmonary vasodilators. RESULTS Recurrent pulmonary hypertension was observed in 11 patients; the state occupation probability of recurrence at 5 years was 9.0% (95% confidence interval: 5.0%-18.9%). Only 1 case (0.6%) of recurrent pulmonary hypertension showed vascular restenosis and reocclusion of previously treated lesions, with more significant hemodynamic and exercise capacity deterioration than the other cases. Additional treatments for recurrent pulmonary hypertension (balloon pulmonary angioplasty in 9 patients, pulmonary vasodilators in 4 patients) improved the mean pulmonary arterial pressure from 27 [26, 29] to 22 [19, 23] mm Hg (p < 0.01). Recurrence had a low probability of transitioning to death in an illness-death model. No specific risk factors for recurrent pulmonary hypertension were identified. CONCLUSIONS Symptomatic recurrent pulmonary hypertension due to vascular restenosis or reocclusion after balloon pulmonary angioplasty was extremely rare. Most cases of recurrent pulmonary hypertension were mild, did not worsen clinically, and had favorable prognoses.

Abstract
Balloon pulmonary angioplasty continues to gain traction as a treatment option for patients with chronic thromboembolic pulmonary disease with and without pulmonary hypertension. Recent European Society of Cardiology guidelines on pulmonary hypertension now give balloon pulmonary angioplasty a Class 1 recommendation for inoperable and residual chronic thromboembolic pulmonary hypertension. Not surprisingly, chronic thromboembolic pulmonary hypertension centers are rapidly initiating balloon pulmonary angioplasty programs. However, we need a comprehensive, expert consensus document outlining critical concepts, including identifying necessary personnel and expertise, criteria for patient selection, and a standardized approach to preprocedural planning and establishing criteria for evaluating procedural efficacy and safety. Given this lack of standards, the balloon pulmonary angioplasty skill set is learned through peer-to-peer contact and training. This document is a state-of-the-art, comprehensive statement from key thought leaders to address this gap in the current clinical practice of balloon pulmonary angioplasty. We summarize the current status of the procedure and provide a consensus opinion on the role of balloon pulmonary angioplasty in the overall care of patients with chronic thromboembolic pulmonary disease with and without pulmonary hypertension. We also identify knowledge gaps, provide guidance for new centers interested in initiating balloon pulmonary angioplasty programs, and highlight future directions and research needs for this emerging therapy.

Abstract
Background and Objectives The ability of a quality of life (QoL) to guide balloon pulmonary angioplasty (BPA) among patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH) has not been fully investigated. This study explored the relationship between QoL scores and hemodynamics in CTEPH patients after BPA and examined whether QoL could be applied as a treatment endpoint. Materials and Methods This cohort study included patients with inoperable CTEPH who had undergone at least four sessions of BPA. The patients' demographic and clinical data as well as hemodynamic parameters and scores from the RAND 36-item short-form QoL questionnaire were recorded and compared before and after BPA. Results After BPA treatments, clinical characteristics, hemodynamic parameters, as well as QoL score improved significantly. A physical component summary (PCS) score of 35 or 46 can be used as the cutoff value for predicting better World Health Organization functional classification (WHO FC). Patients who had a higher PCS would have longer 6-min walk distance (6MWD), lower pulmonary vascular resistance (PVR), and better cardiac output (CO) both before and after BPA. However, 19 patients (55.9%) with a higher PCS score after BPA did not achieve the goal of mean pulmonary arterial pressure (mPAP) ≤30 mmHg. During the follow-up period, a significant reduction of PVR was observed, but the PCS score improved a little. Conclusions QoL is a useful tool for assessing the exercise endurance of patients with inoperable CTEPH treated with BPA, but is insufficient to serve as a treatment endpoint for BPA.

Abstract
INTRODUCTION Up to 50 % of patients surviving a pulmonary embolism (PE) report persisting shortness of breath, reduced physical capacity and psychological distress. As the PE population is heterogeneous compared to other cardiovascular patient groups, outcome measures for assessing physical capacity traditionally used in cardiac populations may not be reliable for the PE population as a whole. This scoping review aims to 1) map performance-based outcome measures (PBOMs) used for assessing physical capacity in PE research, and 2) to report the psychometric properties of the identified PBOMs in a PE population. METHODS The review was conducted according to the Joanna Briggs Institute framework for scoping reviews and reported according to the PRISMA-Extension for Scoping Reviews guideline. RESULTS The systematic search of five databases identified 4585 studies, of which 243 studies met the inclusion criteria. Of these, 185 studies focused on a subgroup of patients with chronic thromboembolic pulmonary hypertension. Ten different PBOMs were identified in the included studies. The 6-minute walk test (6MWT) and cardiopulmonary exercise test (CPET) were the most commonly used, followed by the (Modified) Bruce protocol and Incremental Shuttle Walk test. No studies reported psychometric properties of any of the identified PBOMs in a PE population. CONCLUSIONS Publication of studies measuring physical capacity within PE populations has increased significantly over the past 5-10 years. Still, not one study was identified, reporting the validity, reliability, or responsiveness for any of the identified PBOMs in a PE population. This should be a priority for future research in the field.

Abstract
Dynamic chest radiography (DCR) is a novel functional radiographic imaging technique that can be used to visualize pulmonary perfusion without using contrast media. Although it has many advantages and clinical utility, most radiologists are unfamiliar with this technique because of its novelty. This review aims to (1) explain the basic principles of lung perfusion assessment using DCR, (2) discuss the advantages of DCR over other imaging modalities, and (3) review multiple specific clinical applications of DCR for pulmonary vascular diseases and compare them with other imaging modalities.

Optimal short-term outcomes in balloon pulmonary angioplasty: the minimum frequency of three sessions annually. Ther Adv Respir Dis 2024; 18:17534666241232521. [PMID: 38409856 PMCID: PMC10898305 DOI: 10.1177/17534666241232521] [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: 08/14/2023] [Accepted: 01/29/2024] [Indexed: 02/28/2024] Open
Abstract
BACKGROUND Balloon pulmonary angioplasty (BPA) is typically performed in a sequential manner. OBJECTIVES This study aimed to determine the lowest frequency of BPA for patients who could not reach treatment goals in a short period. DESIGN Retrospective cohort. METHODS We retrospectively enrolled 186 BPA-treated patients diagnosed with chronic thromboembolic pulmonary hypertension. According to the accumulative number of performed BPA sessions or treated pulmonary vessels or the ratio of the number of treated pulmonary vessels/the number of baseline lesions (T/P) prior to the initial occurrence of clinical outcome or censored date, we divided patients into different groups. The principal outcome was clinical worsening. RESULTS After stratifying patients by the number of performed BPA sessions, most baseline parameters were comparable among groups. During follow-up, 31 (16.7%) of 186 patients experienced clinical worsening. The 6-month cumulative clinical worsening-free survival rates of ⩾2 performed sessions group were significantly higher than that of 1 performed session group. The 12-month cumulative rates of clinical worsening-free survival exhibited a declining pattern in the subsequent sequence: ⩾3, 2, and 1 performed BPA sessions, and this trend persisted when follow-up time exceeded 12 months. The 6-, 12-, and 24-month cumulative clinical worsening-free survival rates were comparable between patients with 3 and ⩾4 performed BPA sessions. Similar results were also observed when stratifying patients by the accumulative number of treated pulmonary vessels (⩽8, 9-16, ⩾17) and T/P (⩽0.789, 0.790-1.263, ⩾1.264). CONCLUSION To achieve optimal short-term outcomes, patients might need to undergo ⩾2 BPA sessions or have ⩾9 pulmonary vessels treated or have T/P ⩾0.790 within 6 months, and undergo ⩾3 BPA sessions or have ⩾17 pulmonary vessels treated or have T/P ⩾1.264 within 12 months.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare complication of acute pulmonary embolism. The reasons why clots do not resorb are incompletely understood, but the result is partial or complete fibrothrombotic obstruction of pulmonary arteries. A secondary microvasculopathy aggravates the pulmonary hypertension (PH) as a consequence of high flow and shear stress in the nonoccluded arteries. The treatment of CTEPH has long been purely surgical, but many patients were inoperable because of inaccessible lesions or severe comorbidities. Alternatives were developed, including medical therapy and more recently balloon pulmonary angioplasty (BPA). Depending on the generation of the obstructed vessels, the treatment will be surgical, up to the (sub)segmental level, or by BPA for more distal vessels. PH drugs are used to treat the microvasculopathy. The current paper describes the therapeutic management of inoperable patients: the medical approach with PH drugs used in mono- or combination therapy; the proper use of anticoagulants in CTEPH; the technique, indications, and results at short- and long-term of BPA; the multimodal approach for inoperable patients combining PH drugs and BPA; and the effects of rehabilitation. It shows the importance of a multidisciplinary approach to the disease.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is designated as an intractable disease by the Ministry of Health, Labour and Welfare of Japan, and has an extremely poor prognosis if untreated. Surgical pulmonary endarterectomy is the curative treatment for cases in which the organized thrombi are located in the central part of the pulmonary artery, but there had been no effective treatment for cases in which the thrombi are located in the peripheral part of the pulmonary artery. Recently, balloon pulmonary angioplasty (BPA), a transcatheter procedure to dilate stenotic or occluded lesions in the peripheral pulmonary artery, has been rapidly developed. Although BPA was once a globally abandoned procedure due to hemorrhagic complications, Japanese experts have improved the technique, and its safety and efficacy have been enhanced. As a result, BPA is now being reevaluated worldwide. This review describes the history and development of BPA in the treatment of CTEPH, as well as the status of this treatment in Fukushima Prefecture.

Abstract
BACKGROUND Balloon pulmonary angioplasty (BPA) has beneficial effects on pulmonary hemodynamics, exercise capacity, and quality of life (QOL) in patients with chronic thromboembolic pulmonary hypertension (CTEPH). Recently, emerging evidence suggests a relationship between CTEPH and psychiatric disorders (PD). However, data on the clinical efficacy of BPA in CTEPH patients with PD are lacking. METHODS We retrospectively analyzed 75 patients with inoperable/residual CTEPH who underwent BPA and right-sided heart catheterization before the initial BPA and within 1 year after the last procedure. QOL was evaluated using the European Quality of Life Five Dimension (EQ-5D) scale in 27 patients before and after BPA sessions. Baseline and post-procedural hemodynamic, functional, and QOL parameters were compared between the patients with and without PD. RESULTS Among the 75 participants, 22 (29.3%) patients were categorized in the PD group. Although PD group had a similar mean pulmonary artery pressure level compared with non-PD group (40 ± 7 vs. 41 ± 9 mmHg, p = 0.477), they tended to have unfavorable QOL status (0.63 ± 0.22 vs. 0.77 ± 0.19, p = 0.102). BPA significantly improved pulmonary hemodynamics, laboratory parameters and exercise tolerance in both groups. BPA also significantly improved EQ-5D scores in the non-PD group (from 0.77 ± 0.19 to 0.88 ± 0.13, p < 0.001), but the scores remained unchanged in the PD group (from 0.63 ± 0.22 to 0.67 ± 0.22, p = 0.770). During the long-term period [1,848 (1,055-2,565) days], both groups experienced similar mortality rates (PD 4.6% vs. non-PD 5.7%, p = 1.000). CONCLUSIONS BPA improved hemodynamic and functional parameters irrespective of PD, but its effect on QOL was limited in patients with PD.

Abstract
Over the last few years, the advent of balloon pulmonary angioplasty (BPA) had led to changes in the management of chronic thromboembolic pulmonary hypertension (CTEPH). We reviewed data from 98 CTEPH patients diagnosed during the last decade in a pulmonary hypertension (PH) expert centre. The management modalities of 2 periods (Period A: 2011-15 and Period B: 2016-20) were compared. Age (period A: 72 [58-80] years; period B: 69 [62-79] years), clinical (New York Heart Association (NYHA) functional class III-IV: 25/41, 61% vs 39/57, 68%), and hemodynamic assessments (pulmonary vascular resistance: 7.5 [6.2-8.7] WU vs 8.0 [6.0-10.2] WU) at baseline were not significantly different. Pulmonary endarterectomy was performed in less than one third of patients (12, 29.3% vs 15, 26.3%). For patients not eligible for surgery, medical therapy was mostly prescribed alone during period A (medical therapy alone, patients diagnosed in period A: 61% vs in period B: 17.5%) while it was associated with BPA during period B (medical therapy + BPA, 12% vs 61.4%). The 5-year survival rate was excellent for patients who underwent surgery (96.3%) or BPA (95.2%), but was only 42.1% for patients under oral medication only (p < 0.0001). Patients diagnosed with CTEPH who cannot be operated should undergo BPA. The survival rate after BPA is as good as after surgery and significantly better than that of oral medication only.

Diagnostic accuracy of perfusion-weighted phase-resolved functional lung magnetic resonance imaging in patients with chronic pulmonary embolism. Front Med (Lausanne) 2023; 10:1256925. [PMID: 37822465 PMCID: PMC10562573 DOI: 10.3389/fmed.2023.1256925] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Accepted: 09/11/2023] [Indexed: 10/13/2023] Open
Abstract
Purpose This study aimed to evaluate the diagnostic performance of perfusion-weighted phase-resolved functional lung (PW-PREFUL) magnetic resonance imaging (MRI) in patients with chronic pulmonary embolism (CPE). Materials and methods This study included 86 patients with suspected chronic thromboembolic pulmonary hypertension (CTEPH), who underwent PREFUL MRI and ventilation/perfusion (V/Q) single-photon emission computed tomography/computed tomography (SPECT/CT). PREFUL MRI was performed at 1.5 T using a balanced steady-state free precession sequence during free breathing. Color-coded PW images and quantitative parameters were obtained by postprocessing. Meanwhile, V/Q SPECT/CT imaging was performed as a reference standard. Hypoperfused areas in the lungs were scored for each lobe and segment using V/Q SPECT/CT images and PW-PREFUL MR images, respectively. Normalized perfusion (QN) and perfusion defect percentage (QDP) were calculated for all slices. For intra- and interobserver variability, the MRI images were analyzed 2 months after the first analysis by the same radiologist and another radiologist (11 years of lung MRI experience) blinded to the results of the first reader. Results Of the 86 enrolled patients, 77 met the inclusion criteria (36 diagnosed with CPE using V/Q SPECT/CT and 41 diagnosed with non-CPE etiology). For the PW-PREFUL MRI, the sensitivity, specificity, accuracy, and positive and negative predictive values for the diagnosis of CPE were 97, 95, 96, 95, and 98% at the patient level; 91, 94, 93, 91, and 94% at the lobe level, and 85, 94, 92, 88, and 94% at the segment level, respectively. The detection of segmental and subsegmental hypoperfusion using PW-PREFUL MRI revealed a moderate agreement with V/Q SPECT/CT (κ = 0.65; 95% confidence interval: 0.61-0.68). The quantitative results indicated that the QN was lower in the CPE group than in the non-CPE group [median score (interquartile range, IQR) 6.3 (2.8-9.2) vs. 13.0 (8.8-16.7), p < 0.001], and the QDP was higher [median score (IQR) 33.8 (15.7-51.7) vs. 2.2 (1.4-2.9), p < 0.001]. Conclusion PREFUL MRI could be an alternative test to detect CPE without requiring breath-hold, contrast agents, or ionizing radiation.

Abstract
BACKGROUND The efficacy and safety of percutaneous transluminal pulmonary angioplasty (PTPA) for Takayasu arteritis-associated pulmonary hypertension (TA-PH) remain unclear. OBJECTIVES To examine the efficacy and safety of PTPA in TA-PH. METHODS PubMed, Embase, and the Cochrane Central Register of Controlled Trials Library were searched from inception to August 18, 2022, for articles investigating the efficacy and safety of PTPA for TA-PH. The primary efficacy outcomes were pulmonary vascular resistance (PVR) changes from baseline to re-evaluation and 6-minute walking distance (6MWD). The safety outcome was procedure-related complications. RESULTS Five articles comprising 104 patients with TA-PH who underwent PTPA were included. The scores of article quality, as assessed using the methodological index for nonrandomized studies tool, were high, ranging from 13 to 15 points. The pooled treatment effects of PVR (weighted mean difference [WMD]: -4.8 WU; 95% confidence interval [CI]: -6.0 to -3.5 WU; I2 = 0.0%), 6MWD (WMD: 101.9 m; 95% CI: 60.3-143.6 m; I2 = 70.4%) significantly improved. Procedure-related complications, which predominantly present as pulmonary artery injury and pulmonary injury, occurred in 32.0% of the included patients. Periprocedural death occurred in one patient (1.0%, 1/100). CONCLUSIONS Patients with TA-PH could benefit from PTPA in terms of hemodynamics and exercise tolerance, at the expense of procedure-related complications. PTPA should be encouraged to enhance the treatment response in TA-PH. These findings need to be confirmed by further studies, ideally, randomized controlled trials.

Abstract
BACKGROUND Balloon pulmonary angioplasty (BPA) is a promising interventional treatment for inoperable chronic thromboembolic pulmonary hypertension (CTEPH). Evidence in favor of BPA is growing, but long-term data remain scarce. The Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR) is validated for the assessment of patients with pulmonary hypertension within three domains: symptoms, activity, and quality of life (QoL). The aim of the present study was to evaluate the long-term effects of BPA on these domains in patients with inoperable CTEPH. METHODS Between March 2014 and August 2019, technically inoperable patients with target lesions for BPA were included in this prospective, observational study. CAMPHOR scores were compared between baseline (before the first BPA) and 6 months after the last intervention and also for scores assessed at annual follow-ups. RESULTS A total of 152 patients had completed a full series of BPA interventions and a 28 (interquartile range [IQR]: 26-32) week follow-up. Further follow-up assessments including the CAMPHOR score were performed 96 (IQR: 70-117) weeks, 178 (IQR: 156-200) weeks, and 250 (IQR: 237-275) weeks after the last intervention. From baseline to the last follow-up, CAMPHOR scores for symptoms, activity, and QoL improved from 9 (IQR: 6-14) to 3 (IQR: 0-9) (p < 0.001), 8 (IQR: 5-12) to 4 (IQR: 2-8) (p < 0.001), and 5 (IQR: 2-9) to 1 (IQR: 0-5) (p < 0.001). CONCLUSION BPA leads to long-lasting, significant improvement of symptoms, physical capacity, and QoL in inoperable CTEPH patients.

Emerging Role of Balloon Pulmonary Angioplasty in Chronic Thromboembolic Pulmonary Disease-Insights from the 2022 ESC Guidelines. J Clin Med 2023; 12:5336.

Abstract
In this article, we discuss the topic of chronic thromboembolic pulmonary disease (CTEPD) and the growing role of balloon pulmonary angioplasty (BPA) in its treatment. We present the pathophysiology of CTEPD which arises from an incomplete resolution of thrombi in the pulmonary arteries and leads to stenosis and occlusion of the vessels. The article focuses mainly on the chronic thromboembolic pulmonary hypertension (CTEPH) subpopulation for which prognosis is very poor when left untreated. We describe a multimodal approach to treating CTEPH, including pulmonary endarterectomy (PEA), BPA, and pharmacological therapies. Additionally, the benefits of pharmacological pre-treatment before BPA and the technical aspects of the procedure itself are outlined. It is emphasized that BPA does not replace PEA but serves as a complementary treatment option for eligible patients. We summarized efficacy and treatment goals including an improvement in functional and biochemical parameters before and after BPA. Patients who received pre-treatment with riociguat prior to BPA exhibited a notable reduction in the occurrence of less severe complications. However, elderly patients are still perceived as an especially vulnerable group. It is shown that the prognosis of patients undergoing BPA is similar to PEA in the first years after the procedure but the long-term prognosis of BPA still remains unclear. The 2022 ESC/ERS guidelines highlight the significant role of BPA in the multimodal treatment of CTEPH, emphasizing its effectiveness and recommending its consideration as a therapeutic option for patients with CTEPD, both with and without pulmonary hypertension. This review summarizes the available evidence for BPA, patient selection, procedural details, and prognosis and discusses the potential future role of BPA in the management of CTEPH.

Abstract
Balloon pulmonary angioplasty (BPA) was first described in 2001 and now has evolved into a class I indication for inoperable or residual chronic thromboembolic pulmonary hypertension. This review article aims to describe evidence from studies performed at various pulmonary hypertension (PH) centers across the globe, to better understand the role of BPA in chronic thromboembolic pulmonary disease with and without PH. Additionally, we hope to highlight innovations and the ever-changing safety and efficacy profile of BPA.

Chronic thromboembolic pulmonary hypertension is associated with a loss of total lung volume on computed tomography. World J Radiol 2023; 15:146-156.

Abstract
BACKGROUND Although lung volumes are usually normal in individuals with chronic thromboembolic pulmonary hypertension (CTEPH), approximately 20%-29% of patients exhibit a restrictive pattern on pulmonary function testing.
AIM To quantify longitudinal changes in lung volume and cardiac cross-sectional area (CSA) in patients with CTEPH.
METHODS In a retrospective cohort study of patients seen in our hospital between January 2012 and December 2019, we evaluated 15 patients with CTEPH who had chest computed tomography (CT) performed at baseline and after at least 6 mo of therapy. We matched the CTEPH cohort with 45 control patients by age, sex, and observation period. CT-based lung volumes and maximum cardiac CSAs were measured and compared using the Wilcoxon signed-rank test and the Mann-Whitney u test.
RESULTS Total, right lung, and right lower lobe volumes were significantly reduced in the CTEPH cohort at follow-up vs baseline (total, P = 0.004; right lung, P = 0.003; right lower lobe; P = 0.01). In the CTEPH group, the reduction in lung volume and cardiac CSA was significantly greater than the corresponding changes in the control group (total, P = 0.01; right lung, P = 0.007; right lower lobe, P = 0.01; CSA, P = 0.0002). There was a negative correlation between lung volume change and cardiac CSA change in the control group but not in the CTEPH cohort.
CONCLUSION After at least 6 mo of treatment, CT showed an unexpected loss of total lung volume in patients with CTEPH that may reflect continued parenchymal remodeling.

Abstract
Introduction: Chronic thromboembolic pulmonary hypertension (CTEPH) is a phenotype of pulmonary hypertension due to chronic and multiple organized thrombus. The therapeutic strategy for patients with CTEPH and comorbid protein S deficiency remains unknown due to its rarity. Case: We encountered a 49-year-old male patient with CTEPH and concomitant mild protein S deficiency (type III). We could successfully perform balloon pulmonary angioplasty without any major complications, including thromboembolism and bleeding, followed by standard-dose oral anticoagulation therapy instead of warfarin. Conclusion: A currently established standard therapeutic strategy for CTEPH, including pulmonary angioplasty, may be safe and effective even in patients with concomitant inherent coagulation abnormalities.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare major vessel pulmonary vascular disease that is characterised by fibrotic obstructions deriving from an organised clot. Recent advances in treatments for CTEPH have significantly improved outcomes. Apart from classical surgical pulmonary endarterectomy, balloon pulmonary angioplasty (BPA) and vasodilator drugs that were tested in randomised controlled trials of non-operable patients are now available. In Europe, CTEPH affects males and females equally. In the first European CTEPH Registry, women with CTEPH underwent pulmonary endarterectomy less frequently than men, especially at low-volume centres. In Japan, CTEPH is more common in females and is predominantly treated by BPA. More data on gender-specific outcomes are expected from the results of the International BPA Registry (NCT03245268).

Abstract
Balloon pulmonary angioplasty (BPA) is now a treatment option for patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH). However, the incidence of restenosis and long-term changes in vessel diameters in pulmonary arteries after BPA are unknown. The present study investigated the incidence of restenosis by measuring changes in vessel diameter after BPA. We reviewed 58 patients (168 lesions) with CTEPH who underwent single dilation for the target lesion (type A/B/C lesions) during BPA procedure followed by selective pulmonary angiography more than 6 months after the final BPA procedure. The outcomes of BPA were assessed in terms of pulmonary artery diameters. In a median follow-up of 1.9 (1.2-2.7) years, restenosis occurred in only one case with a type C lesion after BPA (0.6%). In type A/B lesions, the minimal lumen diameter was significantly enlarged at follow-up after BPA [3.48 (2.59-4.34) to 4.22 (3.31-4.90) mm]. In type C lesions, the minimal lumen diameter was unchanged at follow-up after BPA [3.15 (1.96-3.64) to 3.28 (2.38-4.61) mm]. The present results revealed that restenosis after BPA rarely occurs in type A/B/C lesions. Minimal lumen diameters for type A/B lesions continually increased and those for type C lesions did not decrease. Stent implantation in type A/B/C lesions would be unnecessary after BPA.

Abstract
INTRODUCTION Balloon pulmonary angioplasty (BPA) is a less invasive treatment alternative for patients with chronic thromboembolic pulmonary hypertension (CTEPH) who are unable to move forward with pulmonary thromboendarterectomy. This report describes a single-center experience with a nascent BPA program in the United States (US). METHODS All patients who underwent BPA between August 2018-2021 were included in this retrospective, single-center observational cohort. Pre- and post-procedure clinical information was collected, along with procedural characteristics. RESULTS Thirty patients began their BPA series during the study period. The majority of patients had segmental disease (n = 25, 83.3%). A total of 135 BPA procedures were performed on 417 segments. On average, patients completed 4.5 sessions and the majority of patients (n = 23, 76.7%) underwent more than 2. There were 24 episodes of hemoptysis and 20 procedural events that required treatment, typically with either heparin reversal or balloon tamponade. Of 26 participants with completed series, mean PA pressure (-6 mmHg, 95% CI -9 to -4 mmHg, p = 0.0001), PVR (-1.9 Wood units, 95% CI -2.9 to -1.0, p = 0.0002), and pulmonary compliance (-1.0 mL/mmHg, 95% CI -1.5 to -0.5, p = 0.0002) improved. Improvement was also seen in NYHA functional classification and walk distance (p = 0.01). Two deaths occurred, with one death peri-procedurally. CONCLUSION This paper describes an early experience with BPA at a single US center. Improvement in non-invasive and invasive metrics were seen without adding a significant morbidity to an already high-risk patient population.

Abstract
Background While current guidelines require lung ventilation-perfusion (V/Q) scanning as the first step to diagnose chronic pulmonary embolism in pulmonary hypertension (PH), its use may be limited by low availability and/or exposure to ionizing radiation. Purpose To compare the performance of dynamic chest radiography (DCR) and lung V/Q scanning for detection of chronic thromboembolic PH (CTEPH). Materials and Methods Patients with PH who underwent DCR and V/Q scanning in the supine position from December 2019 to July 2021 were retrospectively screened. The diagnosis of CTEPH was confirmed with right heart catheterization and invasive pulmonary angiography. Observer tests were conducted to evaluate the diagnostic accuracy of DCR and V/Q scanning. The lungs were divided into six areas (upper, middle, and lower for both) in the anteroposterior image, and the number of lung areas with thromboembolic perfusion defects was scored. Diagnostic performance was compared between DCR and V/Q scanning using the area under the receiver operating characteristic curve. Agreement between the interpretation of DCR and that of V/Q scanning was assessed using the Cohen kappa coefficient and percent agreement. Results A total of 50 patients with PH were analyzed: 29 with CTEPH (mean age, 64 years ± 15 [SD]; 19 women) and 21 without CTEPH (mean age, 61 years ± 22; 14 women). The sensitivity, specificity, and accuracy of DCR were 97%, 86%, and 92%, respectively, and those of V/Q scanning were 100%, 86%, and 94%, respectively. Areas under the receiver operating characteristic curve for DCR and V/Q scanning were 0.92 (95% CI: 0.79, 0.97) and 0.93 (95% CI: 0.78, 0.98). Agreement between the consensus interpretation of DCR and that of V/Q scanning was substantial (κ = 0.79 [95% CI: 0.61, 0.96], percent agreement = 0.9 [95% CI: 0.79, 0.95]). Conclusion Dynamic chest radiography had similar efficacy to ventilation-perfusion scanning in the detection of chronic thromboembolic pulmonary hypertension. © RSNA, 2022 Online supplemental material is available for this article.

Balloon Pulmonary Angioplasty for Chronic Thromboembolic Pulmonary Hypertension: A Systematic Review and Meta-analysis. Cardiovasc Intervent Radiol 2023; 46:5-18. [PMID: 36474104 DOI: 10.1007/s00270-022-03323-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Accepted: 11/16/2022] [Indexed: 12/12/2022]
Abstract
PURPOSE To perform a systematic review and meta-analysis assessing the safety and efficacy of balloon pulmonary angioplasty (BPA) in the treatment of chronic thromboembolic pulmonary hypertension (CTEPH). MATERIALS AND METHODS Systematic literature searches were performed from inception to June 2022 to identify studies assessing BPA for CTEPH. Outcomes of interest included the following functional and hemodynamic measures: (a) six-minute walk distance (6MWD), (b) New York Heart Association (NYHA) status, (c) World Health Organization (WHO)-Functional Class status, (d) cardiac index (CI), (e) mean pulmonary artery pressure (mPAP), (f) mean right atrial pressure (mRAP), and (g) pulmonary vascular resistance (PVR). Subgroup analysis was also performed for BPA in post-pulmonary endarterectomy (PEA) patients. All reported BPA-related complications were also recorded. Forty unique studies with a total of 1763 patients were identified for meta-analysis. RESULTS All functional and hemodynamic parameters improved significantly following BPA; 6MWD increased 70 m (95% CI 58-82; P < 0.001), NYHA class improved by - 0.9 classes (95% CI - 1.0 to - 0.8; P < 0.001), WHO-FC class improved by - 1 classes ((95% CI - 1.2 to - 0.9; P < 0.001), CI increased 0.26 L/min/m2 (95% CI 0.17-0.35; P < 0.001), mPAP decreased - 13.2 mmHg (95% CI - 14.7 to - 11.8; P < 0.001), mRAP decreased - 2.2 mmHg (95% CI - 2.8 to - 1.6; P < 0.001), and PVR decreased - 311 dyne/cm/s-5 (95% CI - 350 to - 271; P < 0.001). Meta-analysis of patients who underwent BPA for persistent pulmonary hypertension post-PEA demonstrated significant improvements in 6MWD, WHO-FC, PVR and mPAP. Most common complications included lung injury (8.16%), hemoptysis (7.07%) and vessel injury (5.05%). CONCLUSION BPA represents a safe and effective treatment option for select individuals with CTEPH with significant improvements in hemodynamic parameters, improved exercise tolerance and a relatively low risk of major complications.

Riociguat and balloon pulmonary angioplasty improve prognosis in patients with inoperable chronic thromboembolic pulmonary Hypertension. J Heart Lung Transplant 2023; 42:134-139. [PMID: 36257870 DOI: 10.1016/j.healun.2022.08.011] [Citation(s) in RCA: 15] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Revised: 07/25/2022] [Accepted: 08/17/2022] [Indexed: 01/31/2023] Open
Abstract
BACKGROUND The combination of riociguat and interventional balloon pulmonary angioplasty (BPA) is currently used to treat patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH). The aim of the present study was to evaluate the impact of this combination therapy on the prognosis of inoperable CTEPH patients by comparing the long-term survival rates of patients undergoing combination therapy with riociguat and BPA with those of inoperable patients from the first international CTEPH registry who did not receive specific treatment. METHODS Between March 2014 and August 2019, 138 technically inoperable patients were included in the present prospective, observational cohort study when they were treated with riociguat and BPA at a single CTEPH referral center. Long-term survival of this cohort was compared using propensity score matching with that of inoperable patients recruited between 2007 and 2009 in the first international CTEPH registry. Kaplan-Meier methods were used to evaluate differences in outcomes. RESULTS Whereas the survival rate in the historical group was 84.6% in the first year, 76.6% in the second, 68.5% in the third, and 58.5% in the fifth year after diagnosis, implementation of riociguat/BPA led to survival rates of 100%, 96.7%, 92.9%, and 90% in the respective follow-up periods. In a comparison of 83 well-matched pairs from the 2 cohorts, survival was markedly better in the group treated with riociguat and BPA than in the historical cohort (HR = 0.145, 95% CI 0.05, 0.421). CONCLUSION The combination of riociguat and BPA for the treatment of inoperable CTEPH is associated with excellent 5-year survival rates.

Abstract
BACKGROUND The aim of this study was to evaluate the effect of balloon pulmonary angioplasty (BPA) using lung perfusion single-photon emission computed tomography (SPECT) in patients with chronic thromboembolic pulmonary hypertension (CTEPH). METHODS AND RESULTS 20 consecutive patients (64 ± 15 years) who were diagnosed with CTEPH and underwent BPA were included in this study. All patients underwent lung perfusion SPECT before and after BPA. The relationship between functional %volume of the lung calculated from the lung perfusion SPECT (FVL-LPSPECT), and other clinical parameters before and after BPA was assessed using the Wilcoxon signed-rank test. The correlation between each parameter and mean pulmonary artery pressure (mPAP) using the Spearman's correlation was performed. To determine predictors of mPAP for evaluating treatment effectiveness, significant parameters were included in multiple regression analysis. After BPA, world health organization functional classification, six-minute walk distance (6MWD), mPAP, and FVL-LPSPECT significantly improved. FVL-LPSPECT (r = - 0.728, P < 0.001) and 6MWD (r = - 0.571, P = 0.009) were significant correlation of mPAP. In the multiple regression analysis, FVL-LPSPECT was the most significant predictor of improvement in mPAP after BPA (P < 0.001). CONCLUSIONS This study demonstrated that the lung perfusion SPECT could be a potential measurement of the effectiveness of BPA in patients with CTEPH.

Abstract
Background Treatment strategy for vascular injury during balloon pulmonary angioplasty (BPA) in patients with chronic thromboembolic pulmonary hypertension (CTEPH) was uncertain. Objectives This study aimed to identify an optimal therapeutic strategy for vascular injury during BPA in patients with CTEPH. Methods This study reviewed 207 patients with CTEPH and 956 BPA procedures between November 1, 2012 and November 30, 2015. Patients who were diagnosed with vascular injury during BPA, which was defined as angiographic signs or sudden respiratory and hemodynamic defects were included in this study. The study investigated the safety and efficacy of the hierarchically systematic treatment strategy including gelatin sponge embolization (GSE). Results More than one-half of the 79 patients and 133 procedures with vascular injury were improved by general treatment with reversal of heparin and high-flow oxygen administration. The investigators performed conventional treatment of proximal vessel occlusion using a guiding or balloon catheter in 47 procedures (35%) in which the culprit vessels could be detected under patients' stable conditions. In 32 procedures (24%) without detected culprit lesions or improvement by conventional treatment, GSE could significantly improve patient condition. The treatment strategy obtained successful bailout in 98% of procedures with vascular injury. No patients who underwent GSE died within 30 days after the treatment. There was no significant difference in cumulative mortality rate (median follow-up: 6.6 years) between groups with or without GSE (15.6% vs 8.2%; adjusted HR: 1.47; 95% CI: 0.25-8.69; P = 0.67). Conclusions Treatment strategy including GSE would be promising for vascular injury during BPA in patients with CTEPH.

Abstract
Background
The COMPERA 2.0 4-stratum (4-S) risk score has been demonstrated superior over the 3-stratum (3-S) one in patients with pulmonary arterial hypertension and medically managed patients with chronic thromboembolic pulmonary hypertension (CTEPH). We aimed to determine the prognostic value of the original 4-S and 3-S COMPERA 2.0 risk score and two new derivative versions in CTEPH patients who underwent balloon pulmonary angioplasty (BPA).
Methods
We retrospectively enrolled 175 BPA-treated patients with CTEPH. We assessed the risk stratification before and after each BPA session of CTEPH patients by the original 4-S and 3-S COMPERA 2.0 risk score (by rounding decimal to the nearest integer) and two new proposed derivative versions: the modified version (by rounding decimal to the next integer) and a hybrid version that fuses the original and modified versions. The primary endpoint was clinical worsening events. The secondary outcomes were achieving low-risk profile and mean pulmonary arterial pressure (mPAP) < 30 mmHg at follow-up. We used the Kaplan–Meier curve analysis to assess the survival differences between stratified patients. The comparative model’s performance was evaluated in terms of discrimination by Harrell’s C-index.
Results
All versions of COMPERA 2.0 4-S model outperformed the 3-S one in discriminating the differences in echocardiographic and hemodynamic parameters and clinical worsening-free survival rates. The original and hybrid 4-S model could independently predict the primary and secondary endpoints, and the hybrid version seemed to perform better. The first BPA session could significantly improve risk profiles, and these changes were associated with the likelihood of experiencing clinical worsening events, achieving a low-risk profile and mPAP < 30 mmHg at follow-up. The number of BPA sessions required to achieve low risk/mPAP < 30 mmHg increased as the baseline risk score escalated.
Conclusions
The COMPERA 2.0 4-S model outperformed the 3-S one in BPA-treated patients with CTEPH. The 4-S model, especially its hybrid version, could be used to predict clinical outcome before the initiation of BPA and monitor treatment response.

Balloon Pulmonary Angioplasty for Takayasu Arteritis and Peripheral Pulmonary Artery Stenosis Mimicking Chronic Thromboembolic Pulmonary Hypertension. Life (Basel) 2022; 12:life12111797. [DOI: 10.3390/life12111797] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Revised: 11/03/2022] [Accepted: 11/04/2022] [Indexed: 11/09/2022] Open
Abstract
Balloon pulmonary angioplasty (BPA) has been reported to be effective and safe to an acceptable level in patients with distal-type, inoperable chronic thromboembolic pulmonary hypertension (CTEPH), resulting in improved long-term survival. However, evidenced treatment options and strategy including medical therapy of antithrombotic therapy, glucocorticoids, immunosuppressants, and pulmonary hypertension (PH)-specific therapies are scarce in patients with significant PH and right heart failure associated with Takayasu arteritis and peripheral pulmonary artery stenosis, both of which mimic CTEPH. Moreover, there has been still concern on safety and lack of established methodology in performing BPA for these conditions. In this report, we would like to review recent publications including several case reports and discuss the efficacy, safety, and suitable methods of BPA in this population.

Abstract
BACKGROUND A few studies have focused on the cause of death from different types of pulmonary hypertension (PH). This study aimed to systematically analyze the primary and secondary causes of death and compare the profiles between different PH groups. METHODS The contribution of PH to death was assessed in precapillary PH (i.e., group 1 [pulmonary arterial hypertension], group 3 [PH associated with lung disease], and group 4 [chronic thromboembolic PH]) using specific criteria; death was classified into three categories: PH death (death due to PH only), PH-related death, and PH-unrelated death. Disorders other than PH that contributed to death were analyzed, and mortality profiles were compared between groups. RESULTS Eighty deceased patients with PH were examined (group 1, n = 28; group 3, n = 39; and group 4, n = 13). The contribution of PH to death was significantly different between the three groups. "PH death" was most common in group 1 (61%), "PH-related death" in group 3 (56%), and "PH-related death" and "PH-unrelated death" in group 4 (38% for both). The highest contributing factor to death other than PH was respiratory failure in group 3 and malignant disease in group 4. CONCLUSIONS Significant variations in the causes of death were observed in groups 1, 3, and 4 PH patients. In addition to PH, respiratory failure and malignant disease significantly contributed to death in group 3 and group 4 PH, respectively. Understanding the precise death cause may be important in achieving better outcomes in PH patients.

Update on balloon pulmonary angioplasty for treatment of chronic thromboembolic pulmonary hypertension. Curr Opin Pulm Med 2022; 28:369-374.

Abstract
PURPOSE OF REVIEW To provide an update on balloon pulmonary angioplasty (BPA) for the treatment of chronic thromboembolic pulmonary hypertension (CTEPH), a pulmonary vascular disease that is characterized by fibro-thrombotic material mechanically obliterating major pulmonary arteries, resulting in increased pulmonary vascular resistance (PVR), progressive pulmonary hypertension (PH) combined with a microscopic pulmonary vasculopathy [1▪▪], right ventricular (RV) failure [2] and premature death. RECENT FINDINGS Data from a most recent CTEPH European registry (2015 and 2016) suggest significantly improved survival [3▪] of CTEPH patients compared with survival in the eighties [4], or with data from 2007 and 2009 [5]. Pulmonary endarterectomy (PEA) is still the gold-standard therapy for CTEPH [6,7]. However, only around two thirds of all CTEPH patients are amenable to surgery [3▪,5]. Patients not suitable for PEA and treated conservatively have a poor prognosis [8]. BPA may have a role for this particular group of patients. [9-11]. Currently, BPA programs are available in many countries, with excellent results at expert centers [12-15,16▪,17,18▪▪]. Based on recent data, BPA seems to have a greater impact on symptomatic and hemodynamic improvement than medical therapy with riociguat alone [15]. SUMMARY The evidence favoring BPA is growing, but there is still a lack of published controlled trials. In addition, treatment concepts including indication, technical performance, use of PH-targeted medication, and the concept of follow-up vary between centers. In addition, there is a significant learning curve impacting outcomes [13]. The data from the International BPA registry will provide answers for some of the open questions.

Abstract
Introduction Chronic thromboembolic pulmonary hypertension (CTEPH) is a complication of prior pulmonary thromboembolism (PE), caused by incomplete clot dissolution after PE. In patients with CTEPH, lifelong anticoagulation is mandatory to prevent recurrence of PE and secondary in situ thrombus formation. Warfarin, a vitamin K antagonist, is commonly used for anticoagulation in CTEPH based on historical experience and evidence. The anticoagulant activity of warfarin is affected by food and drug interactions, requiring regular monitoring of prothrombin time. The lability of anticoagulant effect often results in haemorrhagic and thromboembolic complications. Thus, lifelong warfarin is a handicap in terms of safety and convenience. Currently, the use of direct oral anticoagulants (DOACs) in CTEPH has increased with the advent of four DOACs. The safety of DOACs is superior to warfarin, with less intracranial bleeding in patients with non-valvular atrial fibrillation and venous thromboembolism. Edoxaban, the latest DOAC, also has proven efficacy and safety for those diseases in two large clinical trials; the ENGAGE-AF trial and HOKUSAI-VTE trial. The present trial seeks to evaluate whether edoxaban is non-inferior to warfarin in preventing worsening of CTEPH. Methods and analysis The KABUKI trial (is an investigator-initiated, multicentre, phase 3, randomised, single-blind, parallel-group, warfarin-controlled, non-inferiority trial to evaluate the efficacy and safety of edoxaban versus warfarin (vitamin K Antagonist) in subjects with chronic thromBoembolic pUlmonary hypertension taking warfarin (vitamin K antagonIst) at baseline) is designed to prove the non-inferiority of edoxaban to warfarin in terms of efficacy and safety in patients with CTEPH. Ethics and dissemination This study is approved by the Institutional Review Board of each participating institution. The findings will be published in a peer-reviewed journal, including positive, negative and inconclusive results. Trial registration number NCT04730037. Protocol version This paper was written per the study protocol V.4.0, dated 29 January 2021.

Bilateral versus unilateral balloon pulmonary angioplasty for inoperable chronic thromboembolic pulmonary hypertension. Respir Res 2022; 23:117. [PMID: 35525930 PMCID: PMC9080167 DOI: 10.1186/s12931-022-02017-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Accepted: 04/07/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND To evaluate the safety and efficacy of bilateral balloon pulmonary angioplasty (BPA) as compared with unilateral BPA for patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH). METHOD We reviewed 210 consecutive BPA sessions for 92 CTEPH patients, including 124 unilateral BPA sessions and 86 bilateral BPA sessions. Radiation exposure, operation details, lesions characteristics and the occurrence of complications were compared between unilateral BPA and bilateral BPA. 131 BPA sessions with a hemodynamics follow-up were included for efficacy analysis, in which hemodynamics changes were compared. Logistic regression analysis was used to identify factors associated with the occurrence of complications. RESULT Bilateral BPA treated more lobes, arteries and lesions [3 (2, 4) vs. 2 (1, 3) lobes, p < 0.001; 8 (5.5, 10) vs. 6 (4, 8) vessels, p = 0.003; 9 (7, 12) vs. 8 (5, 10) lesions, p = 0.01] in one single session than unilateral BPA in a comparable operation duration and amount of contrast media given. Overall, the occurrence of complications was similar between bilateral BPA and unilateral BPA [9 (10.5%) vs. 12 (9.7%), p = 0.83]. Hemodynamics effects didn't differ significantly between bilateral BPA and unilateral BPA in a single session [mPAP, - 4.5 ± 8.6 vs. - 3.6 ± 7.3 mmHg, p = 0.52; PVR, - 1.1 (- 3.5, 0.8) vs. - 1.8 (- 5.2, 0.3) Wood units, p = 0.21]. For the initial BPA session, bilateral BPA also treated more lobes, arteries and lesions than unilateral BPA [3 (2, 4) vs. 2 (1, 2) lobes, p < 0.001; 8.0 (5.8, 9.3) vs. 6.0 (4.0, 8.0) vessels, p = 0.04; 9 (6, 12) vs. 7 (4, 10) lesions, p = 0.02]. The occurrence of complications was also similar [5 (13.2%) vs. 5 (9.3%), p = 0.80], even in patients with poor baseline hemodynamics. Univariate regression analysis reveals the number of lobes treated/session, but not bilateral BPA, as predictive factors of complications. CONCLUSION Bilateral BPA may be safely and effectively performed in patients with CTEPH without increasing operation duration and radiation burden, even in patients with unfavorable baseline hemodynamics.

CXCL10 levels in diagnosis and improved hemodynamics in patients with chronic thromboembolic pulmonary hypertension undergoing balloon pulmonary angioplasty. Pulm Circ 2022; 12:e12091. [PMID: 35685949 PMCID: PMC9171940 DOI: 10.1002/pul2.12091] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Revised: 04/09/2022] [Accepted: 04/30/2022] [Indexed: 11/06/2022] Open
Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is a progressive pulmonary vascular disease characterized by pulmonary artery stenosis or obstructions resulting from insufficient thrombus resolution. Chemokine (C‐X‐C motif) ligand 10 (CXCL10) is a chemokine that contributes to the pathogenesis of many autoimmune diseases and cancers. The present study aims to investigate the levels of CXCL10 in patients with CTEPH throughout balloon pulmonary angioplasty (BPA) and its correlation with the improvement of pulmonary hemodynamics. Plasma CXCL10 levels were measured in 38 CTEPH patients with 100 BPA sessions and in 28 healthy controls. Correlations between CXCL10 and pulmonary hemodynamics were investigated. Receiver operating characteristic (ROC) curves were plotted to display the diagnostic value and the predictive ability for perioperative complications of CXCL10 and CXCL10‐related models. Nomograms were plotted to visualize the diagnostic value and the predictive ability for perioperative complications of CXCL10 and CXCL10‐related models. CXCL10 levels are higher in CTEPH patients compared with healthy controls (36.5 [95% confidence interval {CI}: 25.0–51.1] vs. 14.8 [95% CI: 11.1–30.9], p < 0.0001) and decreased significantly after BPA treatment (36.5 [95% CI: 25.0–51.1] vs. 24.7 [95% CI: 17.2–36.6], p < 0.0005). Preoperative CXCL10 levels positively correlated with mean right atrial pressure (r = 0.25), systolic pulmonary artery pressure (PAP; r = 0.28), diastolic PAP (r = 0.33), mean PAP (r = 0.36), pulmonary vascular resistance (r = 0.31), and N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP; r = 0.46). Furthermore, plasma CXCL10 levels adjusting for age and sex displayed a sensitivity of 86.0% and a specificity of 67.9% for discriminating CTEPH patients from healthy controls. Preoperative CXCL10 levels, in combination with NT‐proBNP, predicted perioperative complications with a sensitivity of 100.0% and a specificity of 46.9% as displayed in ROC analysis. In conclusion, circulating CXCL10 might contribute to the evaluation of disease severity in CTEPH patients and be useful to evaluate the treatment effect of BPA. Future studies are warranted to further study the relationship between pulmonary hemodynamics and circulating CXCL10.

Percutaneous Pulmonary Angioplasty for Patients With Takayasu Arteritis and Pulmonary Hypertension. J Am Coll Cardiol 2022; 79:1477-1488. [PMID: 35422244 DOI: 10.1016/j.jacc.2022.01.052] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Revised: 01/10/2022] [Accepted: 01/24/2022] [Indexed: 01/29/2023]
Abstract
BACKGROUND Percutaneous transluminal pulmonary angioplasty (PTPA) is a treatment modality for chronic thromboembolic pulmonary hypertension, but whether it can be applied to Takayasu arteritis-associated pulmonary hypertension (TA-PH), another chronic obstructive pulmonary vascular disease, remains unclear. OBJECTIVES This study sought to investigate the efficacy and safety of PTPA for TA-PH. METHODS Between January 1, 2016, and December 31, 2019, a total of 50 patients with TA-PH who completed the PTPA procedure (the PTPA group) and 21 patients who refused the PTPA procedure (the non-PTPA group) were prospectively enrolled in this cohort study. The primary outcome was all-cause mortality. The safety outcomes included PTPA procedure-related complications. RESULTS Baseline characteristics and medical therapies were similar between the PTPA group and the non-PTPA group. During a mean follow-up time of 37 ± 14 months, deaths occurred in 3 patients (6.0%) in the PTPA group and 6 patients (28.6%) in the non-PTPA group, contributing to the 3-year survival rate of 93.7% in the PTPA group and 76.2% in the non-PTPA group (P = 0.0096 for log-rank test). The Cox regression model showed that PTPA was associated with a significantly reduced hazard of all-cause mortality in TA-PH patients (HR: 0.18; 95% CI: 0.05-0.73; P = 0.017). No periprocedural death occurred. Severe complications requiring noninvasive positive pressure ventilation occurred in only 1 of 150 total sessions (0.7%). CONCLUSIONS PTPA tended to be associated with a reduced risk of all-cause mortality with acceptable safety profiles and seemed to be a promising therapeutic option for TA-PH patients.

Abstract
Pulmonary hypertension (PH) is characterized by elevated pulmonary arterial pressure (PAP). Although right-heart catheterization is the gold standard method for the diagnosis of PH by definition, various less-invasive imaging tests have been used for screening, detection of underlying diseases-causing PH, and monitoring of diseases. Among them, 4D flow MRI is an emerging and unique imaging test that allows for comprehensive visualization of blood flow in the right heart and proximal pulmonary arteries. The characteristic blood flow pattern observed in patients with PH is vortical flow formation in the main pulmonary artery. Recent studies have proposed the use of these findings to determine not only the presence of PH but also estimate the mean PAP. Other applications of 4D flow MRI for PH include measurement of wall shear stress, helicity, and 3D flow balance in the pulmonary arteries. It is worth noting that 4D flow has also the potential for longitudinal follow-ups. In this review, the clinical definition of PH, summary of conventional imaging tests, characteristics of pulmonary arterial flow as shown by 4D flow MRI, and clinical application of 4D flow MRI in the management of patients with PH will be discussed.

Abstract
Balloon pulmonary angioplasty (BPA) has improved the survival rate of patients with chronic thromboembolic pulmonary hypertension (CTEPH). The resolution of symptoms is one of the remaining goals of BPA. Frailty affects the outcome of cardiovascular diseases or treatments. The aim of this study is to assess the association between frailty and outcome of BPA. The resolution of symptoms is evaluated by the post-BPA World Health Organization functional class (WHO-FC). A total of 54 patients with CTEPH were divided into 2 groups by post-BPA WHO-FC (WHO-FC I group; n = 34 vs. WHO-FC ≥ II group; n = 20). Frailty was assessed by physicians using the clinical frailty scale (CFS) at the point of patient admission for their first BPA sessions. Compared to the WHO-FC ≥ II group, the WHO-FC I group was younger (65.6 ± 13.9 years vs. 74.3 ± 8.0 years) and had a lower CFS (3 [3, 4] vs. 4 [4, 6]) (median [25th, 75th percentiles]). The WHO-FC I achievement rates for each CFS score were CFS 3: 82.8%; 4: 53.8%; 5: 25.0%; 6: 33.3%; and 7: 20.0%. Logistic regression analysis showed that CFS was an independent predictor of WHO-FC I achievement (odds ratio 0.50, p = 0.012), but pre-BPA hemodynamic parameters and age were not independent predictors. Whether WHO-FC I can be achieved is predicted by pre-BPA patient frailty but not by pre-BPA hemodynamic parameters and age.

Abstract
From its identification as a distinct disease entity, understanding and management of pulmonary hypertension has continuously evolved. Diagnostic and therapeutic interventions have greatly improved the prognostic implications of this devastating disease, previously rapidly and uniformly fatal to one chronically managed by multi-disciplinary teams. Improved diagnostic algorithms and active research into biochemical signatures of pulmonary hypertension (PH) have led to earlier diagnosis of PH. Medical therapy has moved from upfront use of continuous intravenous prostaglandins to administration of combinations of oral medications targeting multiple pathways underlying this disease process. In addition to improved medical therapies, recently introduced interventions such as pulmonary endarterectomy and pulmonary artery balloon angioplasty for chronic thromboembolic pulmonary hypertension (CTEPH) give patients an increasing array of treatment options. Despite these many advances, lung transplantation remains the definitive treatment for patients with disease refractory to or progressing on best medical therapy. As our understanding of medical therapy has advanced, so to have best practices for lung transplantation. Recipient selection and approach to organ transplantation techniques have continuously evolved. Mechanical circulatory support has become increasingly employed to bridge patients through lung transplantation in the immediate post transplantation recovery. In this review, we give a history of lung transplantation for PH, an overview of PH, discuss current best practices and look to the future for insights into the care of these patients.

Abstract
Recently, balloon pulmonary angioplasty (BPA) for chronic thromboembolic pulmonary hypertension (CTEPH) and chronic thromboembolic pulmonary disease (CTEPD) has become an established procedure with stable results. The number of elderly CTEPH/CTEPD patients has also increased due to the widespread recognition of the disease concept. However, the reports of BPA in the elderly are limited. The aim of this study was to evaluate the efficacy and safety of BPA in elderly patients (>80 years). From April 2016 to December 2020, 344 BPA sessions (74 patients) were performed. The safety and efficacy of the BPA procedures were compared in the younger group (<80 years; 278 sessions) and the elderly group (≥80 years; 66 sessions). The hemodynamic parameters were significantly improved in both groups (mean pulmonary arterial pressure: 34.4 ± 9.9 → 21.2 ± 6.2 mmHg, p < 0.001 and 33.2 ± 9.6 → 21.8 ± 8.5 mmHg, p < 0.001; pulmonary vascular resistance: 474.5 ± 248.6 → 201.3 ± 108.7 dyne sec cm−5, p < 0.001 and 496.4 ± 290.9 → 260.5 ± 120.2 dyne sec cm−5, p = 0.002, in younger and elderly group, respectively). The rate of death within 30 days of BPA (0.3% vs. 0%, p = 1.000) and use of positive pressure ventilation (1.4% vs. 3.0%, p = 0.600) were not different between the groups (younger vs. elderly, respectively). BPA significantly improved the hemodynamic parameters of elderly CTEPH/CTEPD patients, and the safety is comparable to that of younger patients.

Abstract
Background Management of inoperable chronic thromboembolic pulmonary hypertension (CTEPH) remains a clinical challenge. Currently, riociguat, a soluble guanylate-cyclase stimulator is recommended by international guidelines. More recently, balloon pulmonary angioplasty (BPA) develops as an alternative treatment for inoperable CTEPH. Method This study is a single-center randomized controlled trial. Subjects with inoperable CTEPH are randomized into either a BPA combined with riociguat or riociguat monotherapy group (2:1) and observed for 12 months after initiation of treatment. The primary endpoint is the change in pulmonary vascular resistance from baseline to 12 months after initiation of treatment. The secondary endpoints include 6-min walk distance (6MWD), WHO-FC, NT-proBNP, SF-36, and other hemodynamic parameters. Safety endpoints are analyzed too. Discussion This study aims to compare the efficacy and safety of BPA combined with riociguat and riociguat monotherapy for inoperable CTEPH.

Hospital costs of Balloon Pulmonary Angioplasty (BPA) procedure and management for CTEPH patients: An observational study based on the French national hospital discharge database (PMSI). PLoS One 2021; 16:e0260483. [PMID: 34874972 PMCID: PMC8651124 DOI: 10.1371/journal.pone.0260483] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Accepted: 11/10/2021] [Indexed: 11/30/2022] Open
Abstract
Introduction Since 2014, Balloon Pulmonary Angioplasty (BPA) has become an emerging and complementary strategy for chronic thromboembolic hypertension (CTEPH) patients who are not suitable for pulmonary endarterectomy (PEA) or who have recurrent symptoms after the PEA procedure. Objective To assess the hospital cost of BPA sessions and management in CTEPH patients. Methods An observational retrospective cohort study of CTEPH-adults hospitalized for a BPA between January 1st, 2014 and June 30th, 2016 was conducted in the 2 centres performing BPA in France (Paris Sud and Grenoble) using the French national hospital discharge database (PMSI-MCO). Patients were followed until 6 months or death, whichever occurred first. Follow-up stays were classified as stays with BPA sessions, for BPA management or for CTEPH management based on a pre-defined algorithm and a medical review using type of diagnosis (ICD-10), delay from last BPA procedure stay and length of stay. Hospital costs (including medical transports) were estimated from National Health Insurance perspective using published official French tariffs from 2014 to 2016 and expressed in 2017 Euros. Results A total of 191 patients were analysed; mainly male (53%), with a mean age of 64,3 years. The first BPA session was performed 1.1 years in median (IQR 0.3–2.92) after the first PH hospitalisation. A mean of 3 stays with BPA sessions per patient were reported with a mean length of stay of 8 days for the first stay and 6 days for successive stays. The total hospital cost attributable to BPA was € 4,057,825 corresponding to €8,764±3,435 per stay and €21,245±12,843 per patient. Results were sensitive to age classes, density of commune of residence and some comorbidities. Conclusions The study generated robust real-world data to assess the hospital cost of BPA sessions and management in CTEPH patients within its first years of implementation in France.
