Chronic thromboembolic pulmonary hypertension (CTEPH) is a disease resulting from impaired patency of the pulmonary arteries by a clot, and the treatment method of choice is pulmonary endarterectomy (PEA). In inoperable patients, balloon pulmonary angioplasty (BPA) is recommended, but we need to implement pharmacological bridge therapy to BPA in some cases. We report a case of a 38-year-old male diagnosed with CTEPH, disqualified from PEA due to comorbidity, who developed right ventricular (RV) failure.

Nitrogen-enriched mesoporous carbons were prepared from three chosen commercial activated carbons such as Carbon Black OMCARB C-140, KETJENBLACK EC-600JD and PK 1-3 Norit. HRTEM, SEM, Raman spectra, elemental analysis, XPS studies and widely approved N adsorption-desorption measurements allowed us to evaluate the effectiveness of N atom insertion and its influence on the BET surface area and the pore structure of modified carbons.

Introduction And Aim: The European societies EACTS (European Association for Cardio-Thoracic Surgery) and ESVS (European Society for Vascular Surgery) recommend the establishment of "Aortic Teams" from 2019. In Poland, the first such team was officially established in Specialist University Hospital no. 2 in Szczecin in 2021.

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.
An externalized transapical guidewire (ETAG) technique has been used for safe delivery of high-profile devices through a tortuous aorta to zone 0, which is currently precluded after mechanical artificial aortic valve replacement (AVR). The aim of the study was to report one center's experience (based on 3 cases) of a unique modification to the ETAG technique used for the first time during total endovascular aortic arch repair after AVR. This report contains technical notes regarding a new method of steering the guidewire from the apex inside the artificial aortic valve during total endovascular aortic arch repair after AVR and the details crucial in preparation for this mini-invasive procedure.

Assessment in a multidisciplinary team of experts (CTEPH team) is currently recommended for treatment decision making. The aim of the present study was to report the effects of such an interdisciplinary concept.

Aim: The aim of the study was to investigate the effect of MS on the severity of coronary artery disease (CAD) and cardio-vascular risk evaluated using the GRACE 2.0 risk score and left ventricular ejection fraction (LVEF) in patients with first acute coronary syndrome (ACS) treated with coronary angioplasty.
Patent foramen ovale (PFO) is thought to be a risk factor for decompression illness (DCI). Catheter-based closure procedure reduces the risk of DCI in selected scuba divers with PFO. Major complication of invasive approach are rare, minor, especially heart rhythm disturbances are reported relatively often.

Although the QT prolongation is usually associated with this cardiomyopathy, the life threatening arrhythmias are less frequent than expected. We present middle age woman with torsade de pointes caused by significant QTc interval prolongation on the basis of tako-tsubo cardiomyopathy, which could suggest not always mild course of this syndrome.

Implantation of an automatic cardioverter-defibrillator (ICD) significantly reduces mortality of these patients. T-wave alternans (TWA) analysis is a relatively new method of SCD risk stratification.

Methods: Seventy eight patients (pts) with ACS were randomly divided into group A (39 pts) taking atorvastatin, and group NA (39 pts) not taking any statin for the following six weeks.
Background: The increasing role of percutaneous coronary interventions (PCI) in the treatment of coronary artery disease and relatively high restenosis rate following PCI require the introduction of available, easy to perform and cost-effective tests that would enable detection of restenosis after PTCA and identification of patients at particularly high risk of restenosis.
Aim: To estimate the predictive value of early dobutamine stress echocardiography (DSE) for the assessment of risk of coronary restenosis.
Methods: Thirty-nine patients with a single coronary vessel disease after PCI were enrolled in this study.
