At the time of the ongoing coronavirus pandemic, we are encountering patients who are Covid-19 positive and have severe coronary artery disease. Patients requiring cardiac surgery are particularly challenging. A multidisciplinary discussion aimed at assessing surgery tolerability and considering the most appropriate approach is important given the higher risk of surgical mortality. We report a case of a high-risk Covid-19 positive symptomatic female patient with an acute coronary syndrome and a critical calcified stenosis of the main stem of the left coronary artery. This patient was not suitable for cardiac surgery and she underwent a percutaneous...

Tomáš Janota

Interv Akut Kardiol. 2022;21(2):96-100 | DOI: 10.36290/kar.2022.014  

Intravenous beta blockers have proven to be a reliable class of medications in treating tachyarrhythmias of various underlying causes and in managing severe hypertension. There is an ever-growing number of indications for the use of beta blockers, since the vast majority of medical emergencies result in extreme catecholamine secretion, leading to associated side-effects. These side-effects can be prevented by using beta blockers. Recent findings support the idea that beta blockers can be beneficial in sepsis, shock, acute heart failure, trauma, thermal trauma, and other medical emergencies associated with tachycardia or tachyarrhythmia. Beta blockers...

The number of examinations for acute chest pain in developed countries is rising. The differential diagnosis for chest pain is wide and, even with the use of modern technologies, it is often impossible to determine the exact cause. The choice of optimal diagnostic modalities for a logical and meaningful strategy remains challenging. Decision aid rules have been created for a quick and effective management of patient with chest pain in acute care. They are mentioned in European and American guidelines. This article aims to present an overview of available models for the decision making in the emergency department and explain their benefits, limitations...

Interv Akut Kardiol. 2022;21(2):84-87 | DOI: 10.36290/kar.2022.012  

Sutureless aortic valve replacement is associated with shorter aortic crossclamp times and lower pressures in small aortic roots. Available data are limited on the use of this sutureless method in combined cardiac surgery valve replacement. Combined cardiac surgery valve procedures using a sutureless valve in the aortic position were performed in 11 patients between 2015 and 2020 at the Department of Cardiac Surgery of the University Hospital in Pilsen. The logistic EUROSCORE was 17 ± 7,68, and the aortic cross clamp time 74 ± 11.8 minutes. A benefical postoperative hemodynamic effect was observed in all cases. Only one person with a very...

Interv Akut Kardiol. 2022;21(2):79-83 | DOI: 10.36290/kar.2022.013  

Aim: We aimed to assess the impact of precipitating factors and signs of acute heart failure on the length of hospital stay according to the ejection fraction (EF) subgroups. Methods: We conducted a retrospective study among acute heart failure patients hospitalized at the Department of Cardioangiology in 2017. The most frequent precipitants and signs were included in the multivariate analysis to assess their association with the length of hospital stay. Results: We included 376 patients with a median length of hospital stay 11 days. There were 198, 58, and 120 patients with reduced, mildly reduced, and preserved EF, respectively. In reduced EF,...

Optical coherence tomography (OCT) with a resolution of 10-15 μm is currently the most accurate imaging modality for invasive coronary artery evaluation. As the options of signal and image processing and of using artificial intelligence in medicine progress, so does the evolution of OCT imaging. The article describes the history of OCT development and technical details of this modality, and summarizes the latest data obtained in scientific research. The introduction of novel software tools and hybrid modalities in cardiology may bring new possibilities in quantitative and qualitative assessment of coronary arteries during an interventional procedure.

Triple combination, double meaningReview articles

Vojtěch Novotný

Interv Akut Kardiol. 2022;21(1):41-44 | DOI: 10.36290/kar.2022.002  

The case report presents two views on the concept of "triple combination" in treating a particular patient with coronary artery disease. The first, somewhat untraditional meaning of the two-word expression is used to describe an unusual case of three chronic total occlusions (CTO) in three different coronary territories clinically manifested by heart failure in the setting of ischaemic cardiomyopathy. All the occlusions were gradually recanalized using CTO PCI techniques with a good angiographic and clinical effect. There was a marked improvement in the original systolic left ventricular dysfunction. The individual procedures are illustrated by images...

Interv Akut Kardiol. 2022;21(1):35-40 | DOI: 10.36290/kar.2022.001  

The duration of dual-antiplatelet therapy after percutaneous coronary intervention as well as its composition vary. However, the standard approach was that its termination was followed by long-term administration of acetylsalicylic acid. Recently, studies have become available dealing with a reduced duration of dual-antiplatelet therapy followed by the administration of a P2Y12 inhibitor in monotherapy, most frequently of ticagrelor. These studies include patients with both stable and acute forms of coronary artery disease. The available data suggest that discontinuation of acetylsalicylic acid after a short initial course of dual-antiplatelet therapy...

Current trends in infective endocarditisReview articles

Michal Pazderník

Interv Akut Kardiol. 2022;21(1):27-34 | DOI: 10.36290/kar.2022.004  

According to recently published data, the incidence of infective endocarditis (IE) has been increasing, up to 15 cases per 100,000 population. Due to the still extremely high rate of complications and mortality, the diagnosis and treatment of IE require a comprehensive multidisciplinary approach, hence the role of the "Endocarditis Team" in the treatment of this disease is essential. The use of computed tomography (CT), magnetic resonance imaging (MRI), and nuclear imaging methods (18-FDG PET/CT and SPECT) plays an important role, as these imaging modalities have become part of the diagnostic criteria. Blood culture-negative endocarditis is documented...

Stroke and/or transient ischemic attack prophylaxis from the perspective of an interventional cardiologistReview articles

Bronislav Janek

Interv Akut Kardiol. 2022;21(1):19-26 | DOI: 10.36290/kar.2022.007  

Stroke is one of the most common causes of permanent disability and death in economically developed countries. Ischemic strokes and transient ischemic attacks account for 85% of all these events. The paper deals with two the main causes of central thromboembolism: non-valvular atrial fibrillation and paradoxical embolization with evidence of patent foramen ovale as well as the possibilities of catheterization treatment in their prophylaxis.
