Abstract Pulsed field ablation (PFA) is an emerging technology for the treatment of atrial fibrillation (AF), which pre-clinical and early-stage clinical data are suggestive some degree preferentiality to myocardial tissue without damage adjacent structures. Here in MANIFEST-17K study we assessed safety PFA by studying post-approval use this modality. Of 116 centers performing with a pentaspline catheter, were received from 106 (91.4% participation) regarding 17,642 patients undergoing (mean...
Abstract Aims Data on the hybrid atrial fibrillation (AF) treatment are lacking in patients with structural heart disease undergoing concomitant CryoMaze procedures. The aim was to assess whether timely pre-emptive catheter ablation would achieve higher freedom from AF or tachycardia (AT) and be associated better clinical outcomes than surgical alone. Methods results trial investigated non-paroxysmal coronary artery bypass grafting and/or valve repair/replacement mandatory procedure who were...
Mushrooms of the genus Ganoderma are known for diverse biological activities, demonstrated both traditionally and experimentally.

Besides exploration most active components in species or genotypes, new formulation techniques development. In recent years, there has been a growing interest use nanomaterials because significant pharmacology applications as substance carriers. Applying nanoparticles...
Ischaemic stroke, especially in the younger population, is an important cause of morbidity and mortality. When compared with older underlying aetiology stroke young includes higher rates cardioembolic disease congenital heart anomalies. Paradoxical embolism may be ischaemic cerebral events, which has to ruled out patients no other evident aetiology. A persistent left superior vena cava (PLSVC) that drains into atrium a very rare anomaly occurring postnatal life embolic events such as...
Abstract Introduction Frequent ventricular premature complexes (VPCs) may cause symptoms and/or lead to deterioration of LV systolic function. Although frequent VPCs be abolished by catheter ablation, it challenging in case their origin from the papillary muscles (PMs). Our collaborative study aimed analyze detail site and outcome ablation. Methods Consecutive 34 patients (males: 68%; aged 62 ± 12 years; ejection fraction: 50 9%) undergoing ablation originating PMs were included. All...
Atrial fibrillation is known very frequent cause of ischemic stroke. Undetected paroxysmal atrial (PAF) thus often considered a possible cryptogenic stroke (CIS). The aim this prospective study was to detect PAF using ECG Holter monitoring and determinate whether prolongation the 3 weeks would increase detection rates in young CIS patients ≤ 50 years.The set consisted IS years enrolled HISTORY (Heart Ischemic STrOke Relationship studY) (NCT01541163). defined according TOAST criteria...
Úvod: Hrudní pás umožňuje pořídit 1svodový EKG záznam. Získaná data byla validována pro měření srdeční frekvence a rovněž i detekci fibrilace síní díky srovnání s krátkými záznamy z holterovského u selektovaných pacientů. Zatím ale nebyla ověřena možnost vyhodnocení dlouhých záznamů neselektovaných kardiologických pacientů se širokým spektrem srdečních chorob. Metodologie výsledky: Do studie bylo zařazeno 54 hospitalizovaných 53 ambulantních zdravých kontrol (n = 161 celkově). U všech...
<b><i>Background:</i></b> Undetected atrial fibrillation (AF) is often suspected as the possible cause in patients with cryptogenic ischemic stroke (IS), especially elderly population. In young IS patients, prevalence of AF, particularly paroxysmal form, remains still not enough established. Our aim was to assess presence AF using a long-term electrocardiography (ECG) Holter monitoring. <b><i>Methods:</i></b> The study set consisted acute ≤50...
A substantial proportion of arteriovenous fistulas fail to function adequately for hemodialysis. Existing studies on fistula failure prediction assess patency rather than the more clinically relevant outcome function. We hypothesized that preoperative demographic and ultrasound characteristics, postoperative assessment by an experienced vascular access nurse would predict which will not hemodialysis.Prospective cohort study chronic kidney disease patients at a tertiary care center in...
V tomto přehledovém článku shrnujeme již zavedené i nové elektroanatomické mapovací systémy a technologie pro katetrizační ablaci arytmií, zejména fibrilace síni. posledních letech počet katetrizačních ablací exponenciálně roste díky technologickým pokrokům umožňujícím komplexní katétrové ablace. Kvalita současných systémů mapování je dostatečně vysoká jak standardní ablace, jako izolace plicních žil, tak hodnocení komplexních arytmií. Nadále jsou vyvíjeny nástroje s cílem usnadnit...
Atrial fibrillation (AF), typical atrial flutter (AFL), and other tachycardias (ATs) are common in patients with pulmonary hypertension. Frequently, several supraventricular arrhythmias successively observed individual patients. We investigated the hypothesis of whether more extensive radiofrequency catheter ablation bi-atrial arrhythmogenic substrate instead clinical arrhythmia alone results superior outcomes arterial hypertension (PH) arrhythmias.Patients combined post- pre-capillary or...
Atrial fibrillation is common in patients with structural heart disease who are undergoing cardiac surgery. Surgical CryoMaze has been shown to be an effective treatment several trials, but success rates have varied considerably, between 47-95%. The sequential hybrid approach, combining surgical followed by radiofrequency catheter ablation, can achieve high freedom from atrial arrhythmias. However, concomitant treatment, data comparing the approach alone lacking.The SurHyb study was designed...

Almost 114,000 were implanted 2021, which 27.9% single-chamber, 67.4% dual-chamber 4.6% biventricular. The annual number implantations has been steadily increasing 6% decline 2020 increased reductions...
Leadless pacemakers (PMs) were recently introduced to address the complication rate of standard PMs with transvenous leads.A 34-year old male a history intravenous substance abuse and chronic type C hepatitis developed complete atrioventricular block after cardiac surgery for infective endocarditis. Repeatedly, endo- epi-cardially implanted had be explanted due infection. A leadless MICRA pacemaker was successfully dislocation into pulmonary artery several days implantation. The PM retrieved...
