RESUMEN
PURPOSE: Intermediate-high-risk pulmonary embolism (IHR PE) is a challenging form of embolism obstruction that causes right ventricular (RV) dysfunction. The optimal management of IHR PE has not been established. This single-center prospective, observational study aimed to evaluate the efficacy and safety of complex catheter-directed therapy (CDT) - catheter-directed mechanical aspiration thrombectomy (CDMT) supplemented with catheter-directed thrombolysis (hybrid CDT) in comparison to CDMT alone for IHR PE. METHODS: A propensity score based on the pulmonary embolism severity index class and Miller obstruction index (MOI) was calculated, and 21 hybrid CDT cases (mean age 54.8 (14.7) years, 9/21 women) were matched with 21 CDMT cases (mean age 58.8 (14.9) years, 13/21 women). The baseline demographics, clinical, and treatment characteristics were analyzed. RESULTS: No significant differences were detected regarding baseline demographics and PE severity parameters. Hybrid CDT demonstrated a higher reduction in mean pulmonary artery pressure (mPAP) (hybrid CDT: median mPAP reduction 8 mmHg (IQR: 6-10 mmHg) vs CDMT: median mPAP reduction 6 mmHg (IQR: 4-7 mmHg); P = 0.019), MOI score (hybrid CDT: median change - 5 points (IQR: 5-6 points) vs CDMT median change - 3 points (IQR: 3-5 points); P = 0.019), and median RV: left ventricular ratio (hybrid CDT: median change 0.4 (IQR: 0.3-0.45) vs CDMT median change 0.26 (IQR: 0.2-0.4); P = 0.007). No major bleeding was observed. Both the hybrid CDT and CDMT alone treatments are safe and effective in managing IHR PE. CONCLUSIONS: Hybrid CDT is a promising technique for the management of IHR PE with insufficient thrombus load reduction by CDMT. TRIAL REGISTRATION: NCT0447356-registration date 16 July 2020.
RESUMEN
BACKGROUND: Recent studies revealed that alterations in glucose and lipid metabolism in idiopathic pulmonary arterial hypertension (IPAH) are associated with disease severity and poor survival. However, data regarding the impact of diabetes mellitus (DM) on the prognosis of patients with IPAH remain scarce. The aim of our study was to determine that impact using data from a national multicentre prospective pulmonary hypertension registry. METHODS: We analysed data of adult patients with IPAH from the Database of Pulmonary Hypertension in the Polish population (BNPPL) between March 1, 2018 and August 31, 2020. Upon admission, clinical, echocardiographic, and haemodynamic data were collected at 21 Polish IPAH reference centres. The all-cause mortality was assessed during a 30-month follow-up period. To adjust for differences in age, body mass index (BMI), and comorbidities between patients with and without DM, a 2-group propensity score matching was performed using a 1:1 pairing algorithm. RESULTS: A total of 532 patients with IPAH were included in the study and 25.6% were diagnosed with DM. Further matched analysis was performed in 136 patients with DM and 136 without DM. DM was associated with older age, higher BMI, more advanced exertional dyspnea, increased levels of N-terminal pro-brain natriuretic peptide, larger right atrial area, increased mean right atrial pressure, mean pulmonary artery pressure, pulmonary vascular resistance, and all-cause mortality compared with no DM. CONCLUSIONS: Patients with IPAH and DM present with more advanced pulmonary vascular disease and worse survival than counterparts without DM independently of age, BMI, and cardiovascular comorbidities.

Introduction: Microvascular changes play a significant role in systemic sclerosis (SSc) and mixed connective tissue disease (MCTD). The most serious complications of SSc and MCTD are lung fibrosis (LF) and pulmonary hypertension (PH). Aim: To determine the relationship of the changes observed in capillaries with the serological profile, LF, PH, and finger ulcerations in patients with SSc and MCTD. Material and methods: The tested group comprised 80 persons (61 SSc, 19 MCTD); mean age 53.6 ±13.6 years. Patients were qualified to the LF group based on HRCT. Likelihood of PH was determined using echocardiography. The presence of antinuclear antibodies (ANA) was assessed using indirect immunofluorescence, while ANA profile, and sclerosis profile were assessed using EUROIMMUN kits, and antiphospholipid antibodies (aPL) using the ELISA method. Capillaroscopy was performed using the Nikon CPS 160 optical microscope. Results: The following were found: a relationship between occurrence of anti-SS-A (p = 0.006) and anti-centromere B antibodies (p = 0.012) and ramified vessels, between anti-SS-B and capillary haemorrhages (p = 0.019), a positive correlation between NOR90 antibodies and winding loops (p = 0.021), PM-Scl 100 antibodies and enlarged vessels (p = 0.033), a negative correlation between Scl-70 antibodies and winding loops (p = 0.033), and a relationship between aCL and winding loops (p = 0.002). No relationship between the capillaroscopy image and PH risk was found. A positive correlation was found between avascularisation areas and LF and between giant capillaries and finger ulcerations. A negative correlation was found between U1-RNP antibodies and finger ulcerations (p = 0.009), and a positive correlation between antibodies to fibrillarin and ulcerations (p = 0.028). Conclusions: SS-A, SS-B and anti-centromere antibodies are associated with the late phase of sclerodermic microangiopathy. Avascularisation areas significantly correlate with a higher prevalence of LF. U1-RNP antibodies have a protective role, while anti-fibrillarin antibodies are the risk factor for finger ulcerations.
RESUMEN
OBJECTIVES: We sought to assess the technical and clinical feasibility of continuous aspiration catheter-directed mechanical thrombectomy (CDT) in patients with high- or intermediate-high-risk pulmonary embolism (PE). METHODS AND RESULTS: Fourteen patients (eight women and six men; age range: 29-71 years) with high- or intermediate-high-risk PE and contraindications to or ineffective systemic thrombolysis were prospectively enrolled between October 2018 and February 2020. The Indigo Mechanical Thrombectomy System (Penumbra, Inc., Alameda, California) was used as CDT device. Low-dose local thrombolysis (alteplase, 3-12 mg) was additionally applied in three patients. Technical and procedural success was achieved in 14 patients (100%). Complete or nearly complete clearance of pulmonary arteries was achieved in nine patients (64.3%), whereas partial clearance was achieved in five (35.7%). A significant improvement in the pre- and postprocedural patients' clinical status was observed in the following fields (median; interquartile range): heart rate (110; 100-120/min vs. 85; 80-90/min; p < 0.0001), systolic blood pressure (106; 90-127 mmHg vs. 123; 110-133 mmHg; p = 0.049), arterial oxygen saturation (88.5; 84.2-93% vs. 95.0; 93.8-95%, p = 0.0051), pulmonary artery systolic pressure (55; 44-66 mmHg vs. 42; 34-53 mmHg; p = 0.0015), Miller index score (21.5; 20-23 vs. 9.5; 8-13; p < 0.0001) and right ventricular/left ventricular ratio (1.3; 1.3-1.5 vs. 1.0; 0.9-1.0; p < 0.0001). No major periprocedural bleeding was detected. CONCLUSIONS: CDT is a feasible and promising technique for management of high- or intermediate-high-risk PE to decrease thrombus burden, reduce right heart strain, and improve hemodynamic and clinical status. Some patients may benefit from simultaneous local low-dose thrombolytic therapy. Nevertheless, its criteria and role in CTD-managed patients require further elucidation.

BACKGROUND: Upregulation of the immune system is regarded to play an important role in the etiopathobiology of pulmonary arterial hypertension (PAH) and inoperable chronic thromboembolic pulmonary hypertension (CTEPH). To the best of our knowledge, neopterin (NP) has never been investigated in patients with PAH and CTEPH. OBJECTIVES: The aim of the study was to evaluate the concentration of NP in blood in order to examine its impact on outcome and relationship with disease severity in that population. METHODS: Serum concentration of NP was analysed prospectively in 50 patients (36 with PAH and 14 with CTEPH vs. 31 healthy controls) and assessed in relation to clinical parameters and outcome. RESULTS: NP concentration in the PAH and CTEPH groups combined was significantly higher than in the control group (8.68, 6.39-15.03 vs. 5.14, 4.16-5.98 nmol/L, p < 0.0000001). During 9 months of follow-up, clinical deterioration occurred in 18 patients (including 8 deaths), and NP concentration in this group was higher when compared to stable patients (15.6, 8.52-25.13 vs. 7.87, 6.18-9.89, p = 0.002). The cutoff value of NP derived from ROC curve analysis was 15.3 nmol/L (p = 0.002, AUC 0.77, p = 0.0004, HR = 4.35, 95% CI 1.43-13.18, log-rank test). On Cox regression analysis, NP predicted clinical deterioration (p = 0.009, 95% CI 1.01-1.06). NP correlated positively with NT-proBNP (p < 0.001), red blood cell distribution width (p < 0.001), and right atrium area (p = 0.002) and inversely with 6-min walking test (p = 0.002) and peak oxygen consumption (p = 0.001). CONCLUSIONS: NP concentration is increased in patients with PAH and inoperable CTEPH. Elevated NP concentration is associated with adverse clinical outcomes and correlates with clinical parameters.

BACKGROUND: Red blood cells distribution width (RDW) predicts survival in cardiovascular diseases. Little is known about the variability of RDW level over time among patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). To our knowledge, RDW has never been analysed as a marker of response to specific treatment. MATERIALS AND METHODS: We retrospectively analysed 77 patients for: i) RDW measured during the last hospitalisation before death or during the last follow-up (RDWlast); ii) mean RDW from all hospitalisations during the entire follow-up of the patient (RDWmean); iii) maximum RDW of all hospitalisations of each patient (RDWmax). In order to assess response to specific treatment and association with prognosis, we compared RDW levels (obtained from 56 patients) before and 3 to 6 months after introduction or intensification of treatment in both the alive and deceased group. RESULTS: Twenty-eight of 77 patients died, whereas in specific drugs treatment response analysis, 22 of 56 patients died during follow-up. The cut-off values derived from the ROC analysis and assessed using the log-rank test were significant for RDWlast (p<0.0001), RDWmean (p<0.001) and RDWmax (p=0.02). A decrease in RDW levels after introduction or intensification of specific treatment was significant (p=0.015) in survivors, whereas there was no significance (p=0.29) in decrease in RDW levels in non-survivors after change of therapy. CONCLUSIONS: Red blood cells distribution width might be a potential prognostic biomarker in patients with PAH and inoperable CTEPH. The decrease in RDW level after introduction or escalation of PAH-targeted and CTEPH-targeted drugs is associated with a good treatment response and better prognosis.

BACKGROUND: Subcutaneous treprostinil is a prostacyclin analogue used to treat pulmonary arterial hypertension (PAH). Due to local pain it can cause a deterioration of heart related quality of life (HRQoL) or even abandonment of treatment. The aim of this paper was to assess the feasibility of treatment with intravenous treprostinil administered by means of the Lenus Pro® implantable pump. METHODS: This was a retrospective, multi-center study involving 12 patients (8 females) with PAH treated with a subcutaneous infusion of treprostinil with intolerable pain at the infusion site. Clinical evaluation, including HRQoL assessment with SF-36 questionnaire was performed, before pump implantation and 2-9 months after. The median time of follow-up time was 14 months (4-29 months). RESULTS: After implantation of the Lenus Pro® pump, no statistically significant changes were observed in the 6-min walking distance and NT-proBNP. After implantation 50% of patients were in II WHO functional class (33% before, p = 0,59). There was a significant improvement in HRQoL within the Physical Component Score (28 ± 7 vs 38 ± 8 pts., p < 0,001) and in specific domains of SF-36 form: physical role (31 ± 7 pts. vs. 41 ± 12 pts., p = 0,03), bodily pain (31 ± 12 vs. 50 ± 14 pts., p = 0,02), and vitality (37 ± 8 pts. vs. 50 ± 14 pts., p = 0,03). During the periprocedural period, one patient developed a recurrent haematoma at the implantation site. During follow-up in one patient, the drug delivering cannula slipped out of the subclavian vein, what required repositioning repeated twice, and in another patient an unexpected increase in the drug administration rate was observed. CONCLUSIONS: In patients with PAH who do not tolerate subcutaneous infusion of treprostinil, the use of the Lenus Pro® implantable pump results in significant subjective improvement of vitality and physical aspect of the HRQoL with acceptable safety profile.

BACKGROUND: Atrial remodelling in pulmonary arterial hypertension (PAH) may lead to higher incidence of supraventricular arrhythmias (SVA). The purpose of this study was to evaluate the efficiency and safety of various methods for treatment of SVA in this group. METHODS: This was a single centre study. Forty-eight patients (33 women and 15 men) aged 19-77 years (median 49 years) were enrolled. There were 30 patients with idiopathic PAH, 10 had PAH associated with connective tissue disease, and eight with congenital heart disease. A retrospective analysis was performed to estimate the prevalence and type of supraventricular arrhythmias, as well as efficiency and safety of treatment methods. Mean follow-up period was 28.8±17.7 months. RESULTS: Supraventricular arrhythmias occurred in 17 patients (35%) and appeared to be atrial fibrillation, flutter or tachycardia. Supraventricular arrhythmias coexisted with elevated mean right atrial pressure in 75%. Four patients had more than one type of SVA. A flutter-like macro-reentrant form of atrial tachycardia dependent on cavo-tricuspid isthmus was found in four cases. The treatment of SVA included typical methods: antiarrhythmic drugs, direct current cardioversion (DCC), and radiofrequency (RF) ablation. All of the therapeutic methods were effective in managing acute arrhythmia. Three patients required re-ablation. Overall mortality: 14 patients (29%) in the whole study group, including six in SVA group (35%) and eight without SVA (26%). CONCLUSIONS: In patients with PAH DCC, pharmacological cardioversion and RF ablation can be applied safely and effectively. Flutter-like macro-reentrant atrial tachycardia dependent on cavo-tricuspid isthmus is observed in this group. It is more challenging, but possible, to successfully treat this arrhythmia with RF ablation.

This paper describe the case of pulmonary thromboembolism (PTE) in pregnancy diagnosed by angio CT The clinical diagnosis of PTE in normal population is difficult. In pregnancy is even more complicated, because physiologic changes of pregnancy can mimic signs and symptoms of PTE. Our patient presented dyspnoea, breathing effort and cyanosis of the mouth at admission. In the check-up there was a distinct murmur just under the heart and tachycardia 115 bpm. The Doppler examination of the venous vessels of the lower extremities was normal. Echocardiography revealed features of right ventricular failure. Due to increased level of D-dimers and echocardiographic features of right-ventricular overload, the suspicion of pneumonic embolism was made. Therefore, in order to verify the initial diagnosis the decision of pulmonary CT angiography was made with the radiological protection of the fetus. This study revealed pulmonary embolism in the form of numerous defects in the contrast fillings of the pulmonary arteries. CT pulmonary angiography is the first imaging test of choice in general population who is suspected to have PTE. However there is no consensus what should be preferred during pregnancy. In this paper the diagnostic concepts and an evidence-based guidelines were discussed in case of PTE in pregnancy as well as its side effects including teratogenicity and oncogenicity. In each case, the risks and benefits must be compared before a decision is taken. In case of thrombosis symptoms in the lower extremities, ultrasound should be taken as the next step, otherwise chest X-ray must be performed. In patients with normal chest X-ray the next step should be scintigraphy but if chest X-ray is abnormal, angio CT is preferred.

We evaluated the prevalence of systemic sclerosis (SSc)-related autoantibodies and their clinical significance and compared the sensitivity of two line immunoblot assays on a prospective study group of 96 Polish SSc patients (ACR-EULAR 2013 criteria) whose sera were assessed by indirect immunofluorescence (HEp-2 and monkey liver) and line immunoblot assays: ANA Profile 3 and Systemic Sclerosis Profile by EUROIMMUN (Lübeck, Germany). Organ involvement was evaluated according to the EUSTAR Minimal Essential Data Set. The following autoantibodies' prevalence was found: Scl-70 (36%), Ro-52 (28%), CENP-B (22%), CENP-A (20%), PM-Scl-75 (20%), PM-Scl-100 (14%), fibrillarin (7%), Th/To (7%), RNA polymerase III 11 kDa (5%), RNA polymerase III 155 kDa (3%), PDGFR (3%), NOR-90 (2%), and Ku (1%). Significant associations between the autoantibodies' presence and organ involvement were found: ATA (dcSSc > lcSSc, less prevalent muscle weakness), Ro-52 (gangrene, DLCO < 60), CENP-B and A (lcSSc > dcSSc, normal CK), CENP-B (rarer digital ulcers and joint contractures), PM-Scl-100 and 75 (PM/SSc overlap, CK increase, muscle weakness, muscle atrophy), PM-Scl-100 (dcSSc unlikely), PM-Scl-75 (lung fibrosis), fibrillarin (muscle atrophy, proteinuria, conduction blocks, palpitations), Th/To (proteinuria, arthritis, muscle weakness, and rarer esophageal symptoms), RNA Polymerase III 11 kDa (arterial hypertension, renal crisis), RNA polymerase III 155 kDa (renal crisis), and PDGFR (dcSSc, tendon friction rubs). Additionally, the Systemic Sclerosis Profile was significantly more sensitive in detecting SSc-related autoantibodies than ANA Profile 3 (p = 0.002). In conclusion, individual autoantibodies associated with specific characteristics of SSc.
RESUMEN
Pulmonary hypertension (PH) is a severe vascular complication of connective tissue diseases (CTD). Patients with CTD may develop PH belonging to diverse groups: (1) pulmonary arterial hypertension (PAH), (2) PH due to left heart disease, (3) secondary PH due to lung disease and/or hypoxia and (4) chronic thromboembolic pulmonary hypertension (CTEPH). PAH most often develops in systemic scleroderma (SSc), mostly in its limited variant. PAH-CTD is a progressive disease characterized by poor prognosis. Therefore, early diagnosis should be established. A specific treatment for PAH-CTD is currently available and recommended: prostacyclin derivative (treprostinil, epoprostenol, iloprost, selexipag), nitric oxide and natriuretic pathway: stimulators of soluble guanylate cyclase (sGC: riociguat) and phosphodiesterase-five inhibitors (PDE5i: sildenafil, tadalafil), endothelin receptor antagonists (ERA: bosentan, macitentan, ambrisentan). Moreover, novel drugs, e.g., sotatercept, have been intensively investigated in clinical trials. We aim to review the literature on recent advances in the treatment strategy and prognosis of patients with PAH-CTD. In this manuscript, we discuss the mechanism of action of PAH-specific drugs and new agents and the latest research conducted on PAH-CTD patients.
RESUMEN
Thanks to advances in interventional cardiology technologies, catheter-directed treatment has become recently a viable therapeutic option in the treatment of patients with acute pulmonary embolism at high risk of early mortality. Current transcatheter techniques allow for local fibrinolysis or embolectomy with minimal risk of complications. Therefore, these procedures can be considered in high-risk patients as an alternative to surgical pulmonary embolectomy when systemic thrombolysis is contraindicated or ineffective. They are also considered in patients with intermediate-high-risk pulmonary embolism who do not improve or deteriorate clinically despite anticoagulation. The purpose of this article is to present the role of transcatheter techniques in the treatment of patients with acute pulmonary embolism. We describe current knowledge and expert opinions in this field. Interventional treatment is described in the broader context of patient care organization and therapeutic modalities. We present the organization and responsibilities of pulmonary embolism response team, role of pre-procedural imaging, periprocedural anticoagulation, patient selection, timing of intervention, and intensive care support. Currently available catheter-directed therapies are discussed in detail including standardized protocols and definitions of procedural success and failure. This expert opinion has been developed in collaboration with experts from various Polish scientific societies, which highlights the role of teamwork in caring for patients with acute pulmonary embolism.

Chronic thromboembolic pulmonary hypertension (CTEPH) is an ominous disease leading to progressive right ventricular failure (RVF) and death. There is no reliable risk stratification strategy for patients with CTEPH. The pulmonary artery pulsatility index (PAPI) is a novel hemodynamic index that predicts the occurrence RVF. We aimed to investigate prognostic value of PAPI in inoperable CTEPH. Consecutive patients with inoperable CTEPH were enrolled. PAPI was calculated from baseline right heart catheterization data. A prognostic cut-off value was determined, and characteristics of low- and high-PAPI groups were compared. The association between risk assessment and survival was also evaluated. We included 50 patients (mean age 64 ± 12.2 years, 60% female). The number of deaths was 12 (24%), and the mean follow-up time was 52 ± 19.3 months. The established prognostic cut-off value for PAPI was 3.9. The low-PAPI group had significantly higher mean values of mean atrial pressure (14.9 vs. 7.8, p = 0.0001), end-diastolic right ventricular pressure (16.5 vs. 11.2, p = 0.004), and diastolic pulmonary artery pressure (35.8 vs. 27.7, p = 0.0012). The low-PAPI group had lower survival as compared to high-PAPI (log-rank p < 0.0001). PAPI was independently associated with survival and may be applicable for risk stratification in inoperable CTEPH.
RESUMEN
The role of electrocardiography (ECG) in chronic thromboembolic pulmonary hypertension (CTEPH) diagnosis and prognosticating has not been yet established. We aimed to assess the relationships of the recommended ECG criteria of right ventricular hypertrophy (RVH) with clot localization in CTEPH patients. ECG patterns of RVH according to the American College of Cardiology Foundation were assessed in patients with newly diagnosed CTEPH. We enrolled 58 (45.3%) patients with proximal and 70 (54.7%) with distal CTEPH. Receiver-operating characteristics curves analysis indicated that the following ECG abnormalities predicted proximal CTEPH localization: RV1 > 6 mm-AUC 0.75 (CI: 0.66-0.84, p < 0.00001); SV6 > 3 mm-AUC 0.70 (CI: 0.60-0.79, p < 0.00001); SI > RI wave-AUC 0.67 (CI: 0.58-0.77, p = 0.0004); RV1:SV1 > 1.0-AUC 0.66 (CI: 0.56-0.76, p = 0.0009); RV1 peak > 0.035 s (QRS < 120 ms)-AUC 0.66 (CI: 0.56-0.75, p = 0.0016); RV1:SV1 > RV3(V4):SV3(V4)-AUC-0.65 (CI: 0.54-0.75, p = 0.0081); RaVR > 4 mm-AUC 0.62 (CI: 0.52-0.71, p = 0.002) and PII > 2.5 mm-AUC 0.62 (CI: 0.52-0.72, p = 0.00162). Pulmonary vascular resistance significantly correlated with amplitudes of RV1 (r = 0.34, p = 0.008), SV6 (r = 0.53, p = 0.000027) and PII (r = 0.44, p = 0.00007). In patients with CTEPH, only 8 out of 23 ECG RVH criteria were useful for differentiating between proximal and distal CTEPH localization and we found that RV1 and SV6 may contribute as potential discriminators.
RESUMEN
BACKGROUND: The pathophysiology of postoperative atrial fibrillation (POAF) is multifactorial. Inflammation and increased oxidative stress play a significant role in POAF development. Neopterin, a biomarker of cellular immune response that enhances oxidative stress and increases the cytotoxic potential of activated macrophages and dendritic cells, was recently found as an independent predictive biomarker of non-operative atrial fibrillation. However, as far as we know, neopterin has never been investigated in POAF. AIMS: The study aimed to assess neopterin concentration as a prognostic biomarker of POAF following coronary artery bypass grafting (CABG). METHODS: One hundred one patients (80.2% males, 85% off-pump, 15% on-pump) were included. Blood samples were taken from patients for analysis of serum neopterin and high-sensitive C-reactive protein (hs-CRP) at three time points: (1) before operation (NP0); (2) on the first day after operation (NP1); and (3) between the fifth and eighth day after the procedure (NP5-8). All factors (preoperative, echocardiographic, and surgical), significant in univariate analysis, were included in a multivariable logistic regression analysis. RESULTS: POAF occurred in 30 patients (30%). In the analyzed multivariable logistic regression models, the independent predictors of POAF occurrence were: higher NP0 concentration (odds ratio [OR], 1.16; 95% confidence interval [CI], 1.02-1.38 for continuous and OR, 3.75; 95% CI, 1.39-10.1 for NP0 cut-off >8.7 nmol/l), higher body mass index (OR, 1.15; 95% CI 1.02-1.29), history of pulmonary disease (OR, 6.72; 95% CI 1.57-28), increased diastolic thickness of the interventricular septum (OR, 1.45; 95% CI, 1.14-1.83), and duration of operation (OR, 1.01; 95% CI, 1.03-1.36). CONCLUSIONS: We found that elevated neopterin concentration before CABG may be a predictive biomarker of POAF.

BACKGROUND: Pulmonary hypertension related to left ventricle heart disease is a common finding in patients with severe aortic stenosis treated with transcatheter aortic valve implantation (TAVI) and is associated with a higher mortality rate. AIMS: The study aimed to analyze the influence of pulmonary artery systolic pressure (PASP) changes after TAVI on long-term survival. METHODS: TAVI was performed in 362 patients between January 2013 and December 2018. The study group comprised 210 patients who underwent a detailed 1-month follow-up. RESULTS: At 1-month, 142 had a stable or decreased PASP value (Group 1), while in 68 patients an increase was observed (Group 2). During 1-year follow-up, 20 patients died (9.5%), 9 in Group 1 and 11 in Group 2 (P = 0.02). The receiver operating characteristic (ROC) curve analysis (area under the curve [AUC], 0.750) revealed a significant value of 1-month measurement for 1-year mortality prediction. The cutoff for the PASP value predictive of mortality was ≤41 mm Hg. A Kaplan-Meier analysis showed significantly higher mortality in patients without a 1-month PASP decrease. In the multivariable analysis, PASP measured at 1-month after TAVI (hazard ratio, 1.040; 95% confidence interval, 1.019-1.062; P < 0.001) was an independent predictor of 1-year mortality. Each 1 mm Hg increase in PASP predicts a 4% increase in the risk of death. CONCLUSION: Decreased or stable value of PASP at 1-month follow-up may predict better 1-year survival after TAVI, while each 1 mm Hg increase in PASP confers a 4% greater risk of 1-year mortality.

BACKGROUNDS: The data concerning the use of bioresorbable vascular scaffolds (BVS) in coronary bifurcation lesions are limited. AIMS: The objective of the study was to evaluate the early and very long-term clinical outcomes of bifurcation stenting with ABSORB BVS. METHODS: One hundred consecutive patients with coronary bifurcation lesions treated with BVS were included. A total of 124 BVS were implanted. Provisional side branch stenting was performed in 66 patients, distal main stenting in 14 patients, systematic T stenting in 2, and T with minimal protrusion (TAP) in 5 patients. Side branch ostial stenting was performed in additional 12 patients. RESULTS: The procedural success was achieved in 98% of patients. In long-term follow-up, the rate of cardiac death was 4.0%, target vessel myocardial infarction was 5.0%, and target vessel revascularization (TVR) was 11%. The cumulative incidence of definite/probable scaffold thrombosis (ST) was 2% at long-term follow-up. Comparison with the historical drug-eluting stents (DES) group revealed higher mortality and major adverse cardiac events rate in the ABSORB group. CONCLUSIONS: Stenting of coronary bifurcation lesions of low-to-moderate complexity with BVS was feasible with good acute performance and acceptable results. However, the risk of death and major adverse cardiovascular events was higher as compared with DES.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare complication of acute pulmonary embolism (APE). Both pharmacological and invasive treatments for CTEPH are available in Poland, and awareness of the disease among physicians is growing. It has been suggested that the COVID-19 pandemic may increase the incidence of CTEPH and facilitate disease detection during more advanced stages of the illness. Thus, the Polish Cardiac Society's Working Group on Pulmonary Circulation, in cooperation with independent experts in this field, launched the updated statement on the algorithm to guide a CTEPH diagnosis in patients with previous APE. CTEPH should be suspected in individuals after APE with dyspnea, despite at least 3 months of effective anticoagulation, particularly when specific risk factors are present. Echocardiography is the main screening tool for CTEPH. A diagnostic workup of patients with significant clinical suspicion of CTEPH and right ventricular overload evident on echocardiography should be performed in reference centers. Pulmonary scintigraphy is a safe and highly sensitive screening test for CTEPH. Computed tomography pulmonary angiography with precise detection of thromboembolic residues in the pulmonary circulation is important for the planning of a pulmonary thromboendarterectomy. Right heart catheterization definitively confirms the presence of pulmonary hypertension and direct pulmonary angiography allows for the identification of lesions suitable for thromboendarterectomy or balloon pulmonary angioplasty. In this document, we propose a diagnostic algorithm for patients with suspected CTEPH. With an individualized and sequential diagnostic strategy, each patient can be provided with suitable and tailored therapy provided by a dedicated CTEPH Heart Team.

BACKGROUND: Balloon pulmonary angioplasty (BPA) is a promising therapy for patients with chronic thromboembolic pulmonary hypertension (CTEPH) who are ineligible for pulmonary endarterectomy. AIMS: The present study aimed to evaluate the safety and efficacy of BPA for CTEPH using the first multicentre registry of a single European country. METHODS: Data were obtained from the Database of Pulmonary Hypertension in the Polish Population (NCT03959748), a prospective, multicentre registry of adult and paediatric pulmonary arterial hypertension (PAH) and CTEPH, for a total of 236 patients with confirmed CTEPH (124 women; mean age 67 years) who underwent 1,056 BPA procedures at eight institutions in Poland. RESULTS: In 156 patients who underwent follow-up assessments after a median of 5.9 (IQR: 3.0-8.0) months after final BPA, the mean pulmonary arterial pressure decreased from 45.1±10.7 to 30.2±10.2 mmHg (p<0.001) and pulmonary vascular resistance from 642±341 to 324±183 dynes (p<0.001), and the six-minute walking test (6MWT) improved from 341±129 to 423±136 m (p<0.001). Pulmonary injury related to the BPA procedure occurred in 6.4% of all sessions. Eighteen patients (7.6%) died during follow-up, including 4 (1.7%) who died within 30 days after BPA. Overall survival was 92.4% (95% confidence interval [CI]: 87.6%-94.9%) three years after the initial BPA procedure. CONCLUSIONS: This multicentre registry confirmed significant improvement of haemodynamic, functional, and biochemical parameters after BPA. Complication rates were low and overall survival comparable to the results of another registry. Therefore, BPA may be an important therapeutic option in patients with CTEPH in Poland.

We aimed to evaluate the clinical course and impact of the SARS-CoV-2 pandemic on the rate of diagnosis and therapy in the complete Polish population of patients (pts) with pulmonary arterial hypertension (PAH-1134) and CTEPH (570 pts) treated within the National Health Fund program and reported in the national BNP-PL database. Updated records of 1704 BNP-PL pts collected between March and December 2020 were analyzed with regard to incidence, clinical course and mortality associated with COVID-19. Clinical characteristics of the infected pts and COVID-19 decedents were analyzed. The rates of new diagnoses and treatment intensification in this period were studied and collated to the proper intervals of the previous year. The incidence of COVID-19 was 3.8% (n = 65) (PAH, 4.1%; CTEPH, 3.2%). COVID-19-related mortality was 28% (18/65 pts). Those who died were substantially older and had a more advanced functional WHO class and more cardiovascular comorbidities (comorbidity score, 4.0 ± 2.1 vs. 2.7 ± 1.8; p = 0.01). During the pandemic, annualized new diagnoses of PH diminished by 25-30% as compared to 2019. A relevant increase in total mortality was also observed among the PH pts (9.7% vs. 5.9% pre-pandemic, p = 0.006), whereas escalation of specific PAH/CTEPH therapies occurred less frequently (14.7% vs. 21.6% pre-pandemic). The COVID-19 pandemic has affected the diagnosis and treatment of PH by decreasing the number of new diagnoses, escalating therapy and enhancing overall mortality. Pulmonary hypertension is a risk factor for worsened course of COVID-19 and elevated mortality.
