BACKGROUND: Advancing the retrograde microcatheter (MC) into the antegrade guide catheter during retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI) can be challenging or impossible, preventing guidewire externalization. OBJECTIVES: To detail and evaluate all the techniques focused on wiring to achieve intubation of the distal tip of a microcatheter, balloon, or stent with an antegrade or retrograde guidewire, aiming to reduce complications by minimizing tension on fragile collaterals during externalization and enabling rapid antegrade conversion in various clinical scenarios. METHODS: We describe the two main techniques, tip-in and rendezvous, and their derivatives such a facilitated tip-in, manual MC-tip modification, tip-in the balloon, tip-in the stent, deep dive rendezvous, catch-it and antegrade microcatheter probing. We provide case studies that demonstrate the effectiveness of these techniques in complex scenarios involving extreme vessel angulation, severe calcification, fragile collaterals, and challenging retrograde MC crossing without externalization. CONCLUSION: The development of advanced variants along with traditional techniques to establish retrograde guidewire connection and antegrade conversion has led to the establishment of a cohesive group of methods known as portal techniques. These approaches serve as strategic advantages in retrograde CTO-PCI, providing a valuable and feasible alternative to conventional retrograde connection techniques, particularly when those techniques fail. Their ability to avoid the externalization process reduces potential damage to collateral channels and the ostium of the donor artery, potentially leading to a reduction in complication rates.

V přehledovém článku jsou shrnuty časné a dlouhodobé výsledky intervenční léčby vrozených srdečních vad (VSV) v Dětském kardiocentru. V letech 1977–2024 bylo provedeno celkem 7027 intervenčních srdečních katetrizací a 17 182 kardiochirurgických operací, včetně 43 transplantací srdce, u 19 120 jedinců, z nichž 17 323 (90,6 %) mělo vrozenou srdeční vadu a 1797 (9,4 %) mělo primární dysrytmie nebo získaná srdeční onemocnění. Časná pooperační úmrtnost se v posledních 20 letech pohybuje kolem 1 %. Dlouhodobá prognóza byla hodnocena u 13 348 dětí s VSV narozených v letech 1978–2020, u kterých bylo provedeno ve stejném časovém období celkem 14 408 kardiochirurgických operací a 4565 intervenčních srdečních katetrizací. Pravděpodobnost přežití 10, 20, 30 a 40 let po první intervenci byla ve skupině 4419 jedinců s komplexními VSV 84,8 %, 82,5 %, 79,4 % a 77,7 % a ve skupině 8929 jedinců s jinými VSV 96,2 %, 95,1 %, 93,9 % a 91,9 % (HR 3,8: CI 3,4–4,3; p < 0,001). K 31. 12. 2020 žilo v České republice po kardiovaskulární intervenci v Dětském kardiocentru celkem 5915 dětí a 6263 dospělých, z nichž komplexní VSV mělo 1868 (31,6 %) dětí a 1796 (28,7 %) dospělých. Závěr: V populaci České republiky přibývají dospělí po kardiovaskulárních intervencích komplexních vrozených srdečních vad v dětství. Dispenzarizace a sledování těchto jedinců ve specializovaných centrech pro dospělé s vrozenou srdeční vadou jsou nezbytné.
This review article summarizes the early and long-term results of interventional treatment of congenital heart disease (CHD) at the Children’s Heart Centre. Between 1977 and 2024, a total of 7,027 interventional cardiac catheterizations and 17,182 cardiac surgeries, including 43 heart transplants, were performed in 19,120 individuals, of whom 17,323 (90.6%) had congenital heart disease and 1,797 (9.4%) had primary dysrhythmias and/or acquired heart disease. Early postoperative mortality has been around 1% over the last 20 years. Long-term prognosis was evaluated in 13,348 children with CHD born between 1978 and 2020, who underwent a total of 14,408 cardiac surgeries and 4,565 interventional cardiac catheterizations during the same time period. The probability of survival at 10, 20, 30 and 40 years after the first intervention was 84.8%, 82.5%, 79.4% and 77.7% in the group of 4,419 individuals with complex CHD and 96.2%, 95.1%, 93.9% and 91.9% in the group of 8,929 individuals with other CHD (HR 3.8: CI 3.4 4.3; p < 0.001). At the end of year 2020, a total of 5,915 children and 6,263 adults were alive after cardiovascular intervention at the Children’s Heart Centre, of whom 1,868 (31.6%) children and 1,796 (28.7%) adults had complex CHD. Conclusion. In the population of the Czech Republic, the number of adults with complex congenital heart disease after cardiovascular interventions in childhood is increasing. Dispensing and follow-up of these individuals in specialized centers for adults with congenital heart disease are essential.

Introduction: The central venous catheter (CVC) and its use represents a step forward in patient treatment, but involves numerous potential complications. Applying nursing standards to clinical practice achieves high-quality nursing care. Design: Cross-sectional quantitative study using a questionnaire. Methods: Quantitative research using questionnaire technique was conducted to examine nurses' knowledge of nursing care for central venous catheters and adherence to nursing standards. The research sample consisted of 256 nurses in selected regional hospitals in the Slovak Republic. The criterion for including nurses in the sample was the provision of CVC care in routine practice. The data were analysed using descriptive statistics and statistical testing methods. Results: The research found that nurses have certain shortcomings in nursing care for central venous catheters. Nurses know how to work correctly according to aseptic procedures (81%), but they are unsure what barrier devices are needed for dressing and treatment (25%). Conclusion: Based on the research results, it can be concluded that despite nurses' knowledge being adequate, it is necessary to provide regular training on the principles of CVC care to reduce infections associated with healthcare.
BACKGROUND: Chronic thromboembolic pulmonary hypertension results from mechanical obstruction of major pulmonary artery lumina with fibrotic tissue. Main treatment has been pulmonary endarterectomy, a complex surgical procedure removing vascular obstruction. However, at least 40% of patients are not candidates for pulmonary endarterectomy because of technical inoperability, comorbidities, or limited access to surgery. Balloon pulmonary angioplasty (BPA) has emerged as an interventional treatment for these patients. OBJECTIVES: The International BPA Registry (NCT03245268) was designed to investigate BPA practice across 18 established centers in the United States, Europe, and Japan. METHODS: A total of 500 patients were prospectively and consecutively enrolled between March 2018 and March 2020, with follow-up until March 2022. Of these, 484 patients were included in the analysis set. RESULTS: Regional differences were seen in patient characteristics (fewer patients with prior pulmonary endarterectomy and more elderly women in Japan) and procedural details (less medical pretreatment, more jugular access, more segments and more occlusive lesions treated per session and patient, less conscious sedation, less contrast and less radiation, shorter intervals between BPA sessions in Japan). Female sex, procedure in Europe/United States, pulmonary hypertension medications at any time, and higher baseline pulmonary vascular resistance (PVR), calculated as transpulmonary pressure gradient divided by cardiac output, emerged as independent predictors of complications during BPA. After a median of 5 (Q1-Q3: 3-6) BPA sessions per patient within a median time of 4.9 months (Q1-Q3: 1.7-11.0 months), a 15-mm Hg (38%) decrease in mPAP, a 332 dynes/s/cm-5 (57%) decrease in PVR, and a 3.2% increase in arterial saturation (medians; P < 0.001) were observed, and there were significant improvements in functional class, 6-minute walk distance, serum levels of N-terminal probrain natriuretic peptide, and Borg dyspnea index. BPA complications occurred in 11.3% of sessions and 33.9% of patients and were mostly hemoptyses. No patient died within 30 days of BPA. CONCLUSIONS: Our data are in line with previous reports on changes of clinical and hemodynamic parameters and complication rates of BPA. Centers with more experience providing BPAs were more likely to achieve a higher percentage decrease in PVR.

Up to one-third of patients referred for transcatheter tricuspid valve intervention (TTVI) have a transvalvular pacemaker (PPM) or implantable cardioverter-defibrillator (ICD) lead in place. Both the electrophysiology and interventional cardiology communities have been alerted to the complexity of decision-making in this situation due to potential interactions between the leads and the TTVI material, including the risk of jailing or damage to the leads. This document, commissioned by the European Heart Rhythm Association and the European Association of Percutaneous Cardiovascular Interventions of the ESC, reviews the scientific evidence to inform Heart Team discussions on the management of patients with a PPM or ICD who are scheduled for or have undergone TTVI.

BACKGROUND: Current therapy for in-stent restenosis (ISR) is based on drug-eluting stents (DES) or drug-eluting balloon catheters. This prospective randomized study compared the efficacy of a novel sirolimus-eluting balloon (SEB) catheter to that of a paclitaxel-eluting balloon (PEB) catheter for the treatment of bare-metal stent (BMS-ISR) or DES-ISR. METHODS: A total of 145 patients with 158 BMS or DES-ISR lesions were randomly assigned to the treatment with either SEB or PEB. The in-segment late lumen loss at 12 months, the 12-month incidence of binary ISR, and major adverse cardiac events (cardiac death, nonfatal acute myocardial infarction, or target lesion revascularization) were compared between groups. RESULTS: The noninferiority of SEB compared with PEB in the treatment of BMS/DES-ISR with respect to late lumen loss was not demonstrated (Δlate lumen loss, -0.024 mm [95% CI, -0.277 to 0.229]; for a noninferiority margin of 0.20 mm), except in the post hoc subanalysis for the BMS-ISR group (-0.203 mm [95% CI, -0.584 to 0.178]). No significant differences in the incidence of repeated binary ISR (31.6% versus 30.4%, P=0.906) or 12-month major adverse cardiac events (31% for both; P>0.999) between the SEB and PEB groups were observed. CONCLUSIONS: The noninferiority of SEB relative to PEB in the treatment of BMS/DES-ISR with respect to late lumen loss was not confirmed.
