RESUMO
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.

OBJECTIVES: The purpose of this article is to present the authors´ comments on the analysis of the conditions for admitting a person to a psychiatric hospital against their will on the basis of a judgment issued by a guardianship court as part of proceedings initiated at the request of an authorized entity, and the assumptions contained therein are based on applicable normative acts. METHODS: The method of analyzing the current provisions of medical law was used, and of the social security law were also referred to. The judicature of the courts, in particular the Supreme Court, was collected, presented and considered, which constitute a practical guide in assessing whether or not the conditions for admitting a patient to a psychiatric hospital without their consent have been met. RESULTS: Placing a mentally ill person in a psychiatric hospital without their consent, in a situation where the person does not pose a direct threat to their health and life, or to the health and life of third parties, and does not pose a threat to public safety, is quite a specific restriction of the human right to freedom, sanctioned by the state. CONCLUSIONS: The provision of Article 29 (1) of the Mental Health Act is a special provision, it should be interpreted strictly, without referring to the principles of broad interpretation or analogy, and the supreme directive of the courts' actions should be the requirement that the ruling should be purposeful from the point of view of the good and interest of the person concerned.

BACKGROUND: Catheter directed therapies (CDT) are widely used in the treatment of acute pulmonary embolism (PE). A multicenter registry was organized to evaluate their application in real life and to determine efficacy and safety of these procedures. Local experience of participating centers in percutaneous techniques for PE treatment was assessed. METHODS: An internet-based registry was designed to collect clinical, echocardiographic and laboratory data of consecutive PE patients treated with CDT in participating centers between 2017 and 2022. RESULTS: Under analysis were 145 consecutive patients with acute PE, aged 61 ± 15 years, treated with CDT in 7 centers: 50 (34.5%) patients with high-risk PE (HRPE), and 95 (65.5%) patients with intermediate-high risk PE (IHRPE). 100 (69%) patients were treated with dedicated devices, in 45 (31%) subjects a pigtail catheter was used. Total PE or CDT related in-hospital mortality in HRPE reached 14% (7 patients), while in IHRPE 3.2% (3 patients) (p = 0.032). 50% of PE or CDT related deaths occurred in patients treated with a pigtail catheter. All-cause mortality in 145 patients was 9.7%, and it was higher in HRPE than in IHRPE (18% vs. 5.3%, p = 0.019). The use of pigtail catheters compared to dedicated systems was associated with higher mortality (20% vs. 5%, p = 0.01). CONCLUSIONS: Catheter directed therapies is a real option of treating PE. It was used as primary therapy also in patients without contraindication for thrombolysis suggesting that clinical practice does not always follow current PE guidelines. Patients treated with dedicated CDT systems had a higher survival rate than subjects treated with pigtail catheters.
RESUMO
BACKGROUND: The impact of left circumflex coronary artery (LCX) ostium atherosclerosis in left main coronary artery (LM) bifurcation disease is not well-known. AIM: The study aimed to assess whether the involvement of LCX ostium carries prognostic implications in patients undergoing unprotected LM percutaneous coronary intervention (PCI). METHODS: Consecutive 564 patients with unprotected LM (ULMCA) disease who underwent LM PCI between January 2015 and February 2021, with at least 1 year of available follow-up were included in the study. The first group was composed of 145 patients with ULMCA disease with LCX ostium stenosis, and the second group consisted of 419 patients with ULMCA disease without LCX ostium stenosis. RESULTS: Patients in the group with ULMCA disease with LCX ostium stenosis were significantly older and had more comorbidities. The two-stent technique was used more often in the group with LCX ostium stenosis (62.8% vs. 14.6%; P <0.001). During 7-year follow-up, all-cause mortality did not differ significantly between groups with and without LCX ostium stenosis (P = 0.50). The use of one-stent or two-stent technique also did not impact mortality in patients with LCX ostial lesions (P = 0.75). Long-term mortality subanalysis for three groups of patients: (1) patients with LM plus LCX ostium stenosis; (2) LM plus left anterior descending artery (LAD) ostium stenosis; (3) LM plus LCX ostium plus LAD ostium stenosis also did not differ significantly (P = 0.63). CONCLUSIONS: LCX ostium involvement in LM disease PCI is not associated with adverse long-term outcomes, which is highly beneficial for the Heart Team's decision-making process.

AIMS: High- (HR) and intermediate-high risk (IHR) pulmonary embolisms (PEs) are related to high early mortality and long-term sequelae. We aimed to describe clinical outcomes and adverse events in IHR and HR pulmonary embolism (PE) treated with catheter-directed mechanical thrombectomy (CDMT) in a real-world population. METHODS AND RESULTS: This study is a multicenter, prospective registry enrolling 110 PE patients treated with CDMT between 2019 and 2022. The CDMT was performed using the 8F Indigo (Penumbra, Alameda, CA, USA) system bilaterally in pulmonary arteries (PAs). The primary safety endpoints included device or PE-related death during the 48-h after CDMT, procedure-related major bleeding, or other major adverse events. Secondary safety outcomes were all-cause mortality during hospitalization or the follow-up. The primary efficacy outcomes were the reduction of PA pressures and change in the right-to-left ventricular (RV/L) ratio assessed in the imaging 24-48 h after the CDMT.71.8% of patients had IHR PE and 28.2% HR PE. 11.8% of patients had a failure and 34.5% had contraindications to thrombolysis, and 2.7% had polytrauma. There was 0.9% intraprocedural death related to RV failure and 5.5% deaths within the first 48 h. CDMT was complicated by major bleeding in 1.8%, pulmonary artery injury in 1.8%, and ischaemic stroke in 0.9%. Immediate haemodynamic improvements included a 10.4 ± 7.8 mmHg (19.7%) drop in systolic PAP (P < 0.0001), a 6.1 ± 4.2 mmHg (18.8%) drop in mean PAP, and 0.48 ± 0.4 (36%) drop in RV/LV ratio (P < 0.0001). CONCLUSION: These observational findings suggest that CDMT may improve hemodynamics with an acceptable safety profile in patients with IHR and HR PE.

Although the treatment and prognosis of patients after heart transplantation have significantly improved, late graft dysfunction remains a critical problem. Two main subtypes of late graft dysfunction are currently described: acute allograft rejection and cardiac allograft vasculopathy, and microvascular dysfunction appears to be the first stage of both. Studies revealed that coronary microcirculation dysfunction, assessed by invasive methods in the early post-transplant period, correlates with a higher risk of late graft dysfunction and death during long-term follow-up. The index of microcirculatory resistance, measured early after heart transplantation, might identify the patients at higher risk of acute cellular rejection and major adverse cardiovascular events. It may also allow optimization and enhancement of post-transplantation management. Moreover, cardiac allograft vasculopathy is an independent prognostic factor for transplant rejection and survival rate. The studies showed that the index of microcirculatory resistance correlates with anatomic changes and reflects the deteriorating physiology of the epicardial arteries. In conclusion, invasive assessment of the coronary microcirculation, including the measurement of the microcirculatory resistance index, is a promising approach to predict graft dysfunction, especially the acute allograft rejection subtype, during the first year after heart transplantation. However, further advanced studies are needed to fully grasp the importance of microcirculatory dysfunction in patients after heart transplantation.
RESUMO
Transcatheter aortic valve implantation (TAVI) is currently becoming the method of choice in high-risk patients with severe aortic valve stenosis. Post-TAVI complications are more common owing to the increasing use of the method. The majority of TAVI complications derive from concomitant aortic stenosis with moderate/severe aortic insufficiency, paravalvular leak, and atrioventricular block. The contemporary TAVI qualification process includes a thorough echocardiography and angio-CT of the aorta, which is crucial in assessing valve measurements, determining the position of the coronary arteries branching from the aorta, and choosing the optimal valve size. We present the case report of an 81-year-old patient admitted to our hospital because of exacerbation of the clinical condition and development of pulmonary edema a few days after TAVI. Despite the reduction of the initial leak, an echocardiographic examination revealed the remaining severe paravalvular aortic leakage. We performed open-heart cardio-thoracic surgery, explanted the TAVI valve, and implanted the biological prosthesis (Edwards Perimount Magna size 25). Introduction of new interventional treatment approaches and the availability of imaging tools have substantially reduced the incidence of significant paravalvular leak and offered a better prognosis for patients undergoing TAVI.
RESUMO
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.
