A Comparative Study of the Rapid (I) and Slow (I) Delayed Rectifier Potassium Currents in Undiseased Human, Dog, Rabbit, and Guinea Pig Cardiac Ventricular Preparations.

To understand the large inter-species variations in drug effects on repolarization, the properties of the rapid (I) and the slow (I) components of the delayed rectifier potassium currents were compared in myocytes isolated from undiseased human donor (HM), dog (DM), rabbit (RM) and guinea pig (GM) ventricles by applying the patch clamp and conventional microelectrode techniques at 37 °C. The amplitude of the E-4031-sensitive I tail current measured at -40 mV after a 1 s long test pulse of 20 mV, which was very similar in HM and DM but significant larger in RM and GM. The L-735,821-sensitive I tail current was considerably larger in GM than in RM.

Case report: Urgent surgical management of pediatric clear cell sarcoma of the kidney with atrial obstruction.

Clear cell sarcoma of the kidney (CCSK) is an uncommon renal neoplasm of childhood. Progression of intracaval or cavoatrial thrombosis is extremely rare and mostly asymptomatic, treated with neoadjuvant therapy followed by surgery. However, in an unstable patient, acute radical surgical intervention is the treatment of choice.

Left ventricular rotational abnormalities in adult patients with corrected tetralogy of Fallot following different surgical procedures (Results from the CSONGRAD Registry and MAGYAR-Path Study).

Background: Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease (CHD). Abnormal aortic dimensions and elasticity parameters have been long described for corrected TOF (cTOF) together with left ventricular (LV) rotational abnormalities, but results are conflicting. The present study focuses on investigating LV rotational mechanics in cTOF, and possible correlation of these parameters with aortic elasticity.

Left ventricular strains correlate with aortic elastic properties in adult patients with corrected tetralogy of Fallot (Results from the CSONGRAD Registry and MAGYAR-Path Study).

Background: Aortopathy is a common phenomenon in tetralogy of Fallot (TOF). The current study was designed to detect left ventricular (LV) deformation abnormalities and its relation to aortic stiffness in corrected TOF (cTOF) using the novel three-dimensional (3D) speckle-tracking echocardiography (3DSTE). Detailed comparative analysis between patients with early palliation-late correction (pcTOF) and early total reconstruction (etrTOF) was also performed.

Reimplantation and long-term mortality after transvenous lead extraction in a high-risk, single-center cohort.

Purpose: The use of cardiac implantable electronic devices (CIEDs) has increased significantly over the last decades. With the development of transvenous lead extraction (TLE), procedural success rates also improved; however, data regarding long-term outcomes are still limited. The aim of our study was to analyze the outcomes after TLE, including reimplantation data, all-cause and cause-specific mortality.

Surgical treatment of heart failure due to giant coronary artery fistula: a case report.

Coronary fistula between the left circumflex coronary artery and the coronary sinus is among the less common forms of coronary artery fistula. A 60-yea\r-old female patient presented to our outpatient cardiology department with symptoms of severe, de novo heart failure.

[Coarctatio aortae: management from infancy to adulthood].

The surgical management of congenital heart defects is changing continuously due to technical development. Aortic coarctation is one of the most frequent congenital heart diseases often with serious symptoms. The authors review the different surgical techniques (end-to-end anastomosis, pathplasty, interposition) and present the up-to-date procedures from infancy to adulthood.

Left Atrial Volumetric and Deformation Analysis in Adult Patients with Dextro-Transposition of the Great Arteries (Insights from the CSONGRAD Registry and MAGYAR-Path Study).

Background: In complete or dextro-transposition of the great arteries (dTGA), the aorta and the pulmonary artery are transposed. The present study was designed to examine dTGAassociated left atrial (LA) volumetric and functional abnormalities in adult patients late after repair and to compare their results to those of healthy controls.

Methods: The present study consisted of 15 dTGA patients (30.

Agricultural systems as potential sources of emerging human mycoses caused by Trichoderma: a successful, common phylotype of Trichoderma longibrachiatum in the frontline.

Trichoderma species are abundant in different agricultural habitats, but some representatives of this genus, mainly clade Longibrachiatum members are also emerging as causative agents of various human diseases with even fatal outcome. Strains of these species frequently show resistance to commonly used azole antifungals. Based on previous data it is hypothesized that Trichoderma isolates identified in human infections derive from environmental-including agricultural-origins.

[Pediatric coronary artery surgery. ].

Pediatric coronary artery surgery for congenital heart disease has become increasingly important in newborns and infants. It is life-saving in unsuccessful coronary transfer surgery, injury of coronary artery during surgery, in pediatric coronary artery bypass surgery (PCABS) due to acquired Kawasaki disease. We review the current surgical role of congenital and acquired coronary artery diseases in newborns and infants.

Five-Year Outcomes after PCI or CABG for Left Main Coronary Disease.

Background: Long-term outcomes after percutaneous coronary intervention (PCI) with contemporary drug-eluting stents, as compared with coronary-artery bypass grafting (CABG), in patients with left main coronary artery disease are not clearly established.

Methods: We randomly assigned 1905 patients with left main coronary artery disease of low or intermediate anatomical complexity (according to assessment at the participating centers) to undergo either PCI with fluoropolymer-based cobalt-chromium everolimus-eluting stents (PCI group, 948 patients) or CABG (CABG group, 957 patients). The primary outcome was a composite of death, stroke, or myocardial infarction.

Off-Pump Versus On-Pump Bypass Surgery for Left Main Coronary Artery Disease.

Background: Concerns remain for a greater risk of incomplete revascularization and reduced survival with off-pump coronary artery bypass grafting (CABG) surgery compared with on-pump surgery particularly in patients with left main disease and extensive underlying myocardial ischemia.

Objectives: This study sought to compare outcomes following off-pump versus on-pump surgery for left main disease by performing a post hoc analysis from the multicenter, randomized EXCEL (Evaluation of XIENCE versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial.

Methods: The EXCEL trial was designed to compare percutaneous coronary intervention with everolimus-eluting stents versus CABG in patients with left main disease.

Neuronal Nitric Oxide Mediates the Anti-inflammatory Effects of Intestinal Ischemic Preconditioning.

Background: Ischemic preconditioning (IPC) can provide a defense against ischemia-reperfusion (IR)-induced acute inflammation and barrier dysfunction in many organs. Because nitric oxide (NO) has been implicated as a trigger or mediator in the IPC mechanism and because neuronal NO synthase (nNOS) is a dominant isoform of NOS in the gastrointestinal tract, our aim was to investigate the role of nNOS in IPC-induced protection after mesenteric IR.

Materials And Methods: Intestinal IR was induced in sodium pentobarbital-anesthetized dogs by clamping the superior mesenteric artery for 60 min followed by 2 h of reperfusion (IR group; n = 7).

Methane inhalation reduces the systemic inflammatory response in a large animal model of extracorporeal circulation.

Objectives: Extracorporeal circulation induces cellular and humoral inflammatory reactions, thus possibly leading to detrimental secondary inflammatory responses. Previous data have demonstrated the bioactive potential of methane and confirmed its anti-inflammatory effects in model experiments. Our goal was to investigate the in vivo consequences of exogenous methane administration on extracorporeal circulation-induced inflammation.

Outcomes following surgical revascularization with single versus bilateral internal thoracic arterial grafts in patients with left main coronary artery disease undergoing coronary artery bypass grafting: insights from the EXCEL trial†.

Objectives: Observational data suggest that the use of a single internal thoracic artery (SITA) may result in inferior outcomes compared with bilateral internal thoracic artery (BITA) use for coronary artery bypass grafting (CABG)-a finding not yet supported by randomized trial outcomes. However, the optimal number of internal thoracic artery grafts in patients with left main coronary artery disease has not been investigated.

Methods: The EXCEL trial randomized 1905 patients with left main coronary artery disease to percutaneous coronary intervention with everolimus-eluting stents versus CABG.

[Perioperative use of levosimendan in cardiac surgery. Hungarian recommendation].

Low output syndrome significantly increases morbidity and mortality of cardiac surgery and lengthens the durations of intensive care unit and hospital stays. Its treatment by catecholamines can lead to undesirable systemic and cardiac complications. Levosimendan is a calcium sensitiser and adenosine triphosphate (ATP)-sensitive potassium channel (I) opener agent.

[The significance of N-terminal pro-B natriuretic peptide in the management of adult patients with congenital heart disease - Results from the CSONGRAD Registry].

Introduction: The prognostic role of B-type natriuretic peptide (BNP) level was confirmed in chronic heart failure and congenital heart diseases irrespective of the aetiology.

Aim: The aim of this study was to compare NT‑proBNP measured in the clinical practice and important clinical and echocardiographic parameters in patients with adult congenital heart diseases under our care.

Method: Data of a total of 70 patients were analysed; 34 patients had corrected tetralogy of Fallot and 19 patients had corrected transposition of the great arteries.

Primary cardiac angiosarcoma: A case report.

Cardiac angiosarcomas are the most common primary malignant cardiac tumors in adults. The diagnosis is often delayed due to nonspecific clinical symptoms at presentation. The cornerstones of diagnosis are echocardiography and the histological evaluation of the cardiac biopsy.

Double-locus lymphoplasmacytic aortitis.

Thoracic aortic aneurysm is an indication for major cardiovascular operative procedures. The etiology is usually hypertension and/or atherosclerotic disease; reaching a certain diameter often results in acute aortic syndrome. Immunoglobulin G4-related aortitis, characterized by lymphoplasmacytic vascular tunica media induration without well-defined underlying infectious or autoimmune systemic causes, is uncommon.

[Multivalve redo surgery in adult patient with complex pulmonary artesia].

30-year-old adult with complex pulmonary atresia (previous surgical procedures: in infancy: exploration, at age of 10: ventricular septal defect closing, unifocalization, homograft implantation between right ventricular outflow tract and pulmonary artery) has biventricular dysfunction because of aortic valve regurgitation, ascending aortic aneurysm, and homograft insufficienty. Multivalve surgery: aortic valve plasty, pulmonary homograft changes for homograft and ascending aortic reconstruction by graft were carried out successfully. In Hungary this was the first case of this type of surgery.

Everolimus-Eluting Stents or Bypass Surgery for Left Main Coronary Artery Disease.

Background: Patients with obstructive left main coronary artery disease are usually treated with coronary-artery bypass grafting (CABG). Randomized trials have suggested that drug-eluting stents may be an acceptable alternative to CABG in selected patients with left main coronary disease.

Methods: We randomly assigned 1905 eligible patients with left main coronary artery disease of low or intermediate anatomical complexity to undergo either percutaneous coronary intervention (PCI) with fluoropolymer-based cobalt-chromium everolimus-eluting stents (PCI group, 948 patients) or CABG (CABG group, 957 patients).
