OBJECTIVES: Conventional cardiopulmonary bypass is the most commonly used means of artificial circulation in cardiac surgery. However, it suffers from the effects of haemodilution and activation of inflammatory/coagulation cascades. Prime displacement (PD) can offset haemodilution and Mini-Extracorporeal Technology (MIECT) can offset both. So far, no study has compared all of these modalities together; hence, we compared the outcomes of these 3 modalities at our institution. METHODS: This was a retrospective analysis of our cardiac surgical database...

OBJECTIVES: Blood cardioplegia (BCP) can be used in different ways to protect the heart from ischaemia-reperfusion injury during cardiac surgery. Because there could be differences between warm and cold intermittent cardioplegia with or without warm reperfusion, we investigated the influence of 2 blood cardioplegia solutions on cardiac function, metabolism and infarct size in stable and infarcted rat hearts. METHODS: The hearts of 32 male Wistar rats were excised and inserted into a blood-perfused isolated heart apparatus...

OBJECTIVES: In recent years, the use of del Nido (DN) cardioplegia has been reported in single-valve surgery or isolated coronary artery bypass surgery with acceptable outcomes. The reports of its use in more complex adult cardiac procedures, however, have been scarce. METHODS: We enrolled a total of 149 adult patients who underwent heart valve surgery with the use of DN cardioplegia between May 2014 and December 2016. For a benchmark comparison, 892 patients who underwent cardiac valve surgery with blood cardioplegia during the same period served as controls...

It is unclear whether non-invasive screening of asymptomatic diabetic patients for coronary artery disease (CAD) may improve cardiac outcomes. Thus, we performed a systematic literature review and meta-analysis of randomised controlled trials (RCT's) on this topic. We searched appropriate RCT's in five online databases (PubMed/MEDLINE, Cochrane Library, Embase, Scopus, and Web of Science) from January 2000 to November 2017 and in 41 recent reviews. Two investigators independently extracted and assessed study data using standardised forms...

AIMS: The aim of this study is to evaluate the impact of metabolic syndrome (MetS) on clinical severity and long term prognosis in patients with myocardial infarction with ST segment elevation (STEMI). METHODS: We examined 507 patients with STEMI who were admitted for primary percutaneous coronary intervention classified according to the presence of MetS using American Heart Association and the National Heart, Lung and Blood Institute definition. After applying these criteria, the patients were categorized in patients with MetS and without MetS...

Bioengineering of a functional cardiac tissue composed of primary cardiomyocytes has great potential for myocardial regeneration and in vitro tissue modeling. However, its applications remain limited because the cardiac tissue is a highly organized structure with unique physiologic, biomechanical, and electrical properties. In this study, we undertook a proof-of-concept study to develop a contractile cardiac tissue with cellular organization, uniformity, and scalability by using three-dimensional (3D) bioprinting strategy...

Hydrogen sulfide (H 2 S) is produced by the action of cystathionine-β-synthase (CBS), cystathionine-γ-lyase (CSE) or 3-mercaptopyruvate sulfurtransferase (3-MST). 3-MST converts 3-mercaptopyruvate (MPT) to H 2 S and pyruvate. H 2 S is recognized as an endogenous gaseous mediator with multiple regulatory roles in mammalian cells and organisms. In the present study we demonstrate that MPT, the endogenous substrate of 3-MST, acts also as endogenous H 2 S donor. Colorimetric, amperometric and fluorescence based assays demonstrated that MPT releases H 2 S in vitro in an enzyme-independent manner...

BACKGROUND: During transradial (TR) access, it remains unclear whether differences in baseline patients characteristics and hemostasis care impact the rate of radial artery occlusion (RAO). We sought to compare the rate of RAO after TR access with the 6 French(Fr) Glidesheath Slender (GSS6Fr, Terumo, Japan) or a standard 5 Fr sheath in Japanese and non-Japanese patients. METHODS AND RESULTS: The Radial Artery Patency and Bleeding, Efficacy, Adverse evenT (RAP and BEAT) trial randomized 1,836 patients undergoing TR coronary angiography and/or interventions to receive the GSS6Fr or the standard 5 Fr Glidesheath (GS5Fr, Terumo, Japan)...

The concomitance between coronary artery disease and carotid artery disease is known and well documented. However, it is a fact that, despite the screening methods for these conditions and the advances in surgical treatment, little has been achieved in terms of reducing the risk of complications in the perioperative period. Publications are scarce, being mostly composed of reports or case series. There is little agreement on the best initial therapeutic approach (myocardial versus carotid revascularization) or the best technique to be used (surgery with or without extracorporeal circulation, hybrid treatments, etc...

Percutaneous treatment of chronic total occlusions (CTO) is one of the major challenges in contemporary interventional cardiology. These lesions are identified in 15% to 30% of all patients referred for coronary angiography. Percutaneous coronary intervention (PCI) of CTOs is technically challenging and requires familiarity with advanced interventional techniques as well as specialty equipment. The choice of strategy and materials is based on clinical features and coronary anatomy; the correct choice is essential to improve the success probability...

BACKGROUND: Coronary artery bypass grafting (CABG) combined with coronary endarterectomy (CE) can be associated with high operative mortality and morbidity. An intra-aortic balloon pump (IABP) has been the most widely used mechanical circulatory support device during perfusion treatment. However, the benefits of preoperative IABP in CABG combined with CE remain unknown. We conducted a retrospective observational study to evaluate the efficacy of preoperative IABP therapy in patients undergoing adjunctive right coronary artery (RCA) endarterectomy...

OBJECTIVE: Familial Hypercholesterolemia (FH) is an inherited disorder of lipid metabolism characterized by very high low density lipoprotein (LDL) cholesterol since birth, resulting in premature atherosclerosis and coronary artery disease (CAD). Cascade screening of children and family members of proven FH individuals can identify more subjects who have high LDL cholesterol or the family mutation and appropriate intervention can reduce their risk of atherosclerosis and prevent its complications...

We investigated the impact of suboptimal platelet reactivity on clinical outcomes after percutaneous coronary intervention (PCI). We enrolled 500 patients with stable coronary artery disease undergoing elective PCI. Platelet reactivity was measured before PCI using the VerifyNow P2Y12 assay. Primary endpoint was the incidence of ischemic or bleeding events at 1 month and 5 years. Patients with high platelet reactivity (HPR) showed significantly higher rates of ischemic events both during the 1st month after PCI (HR 2...

Transesophageal echocardiography (TEE) is the gold standard imaging study used in the diagnosis of infective endocarditis (IE). Computed tomography angiography (CTA) has undergone rapid advancement as a cardiac imaging technique and has previously shown promise in small non-randomized studies for evaluation of IE. We hypothesized that cardiac CTA would perform similarly to TEE in the detection of endocarditic lesions and that there would be no difference in clinical outcomes whether the coronary arteries were evaluated by CTA or invasive coronary angiography (ICA)...

One particular complexity of coronary artery is the natural tapering of the vessel with proximal segments having larger caliber and distal tapering as the vessel get smaller. The natural tapering of a coronary artery often leads to proximal incomplete stent apposition (ISA). ISA alters coronary hemodynamics and creates pathological path to develop complications such as in-stent restenosis, and more worryingly, stent thrombosis. By employing state-of-the-art computer-aided design software, generic stent hoops were virtually deployed in an idealized tapered coronary artery with decreasing malapposition distance...

Endothelial dysfunction is a form of subclinical cardiovascular disease that may be involved in preterm birth and small-for-gestational-age deliveries. However, concentrations of biomarkers of endothelial dysfunction before pregnancy have rarely been measured. We hypothesized that higher levels of biomarkers of endothelial dysfunction (cellular adhesion molecules and selectins) would be associated with odds of preterm birth and/or small-for-gestational-age deliveries. We included 235 women from the Coronary Artery Risk Development in Young Adults (CARDIA) study who were nulliparous at Y7, reported ≥1 live birth through Y25, and had ≥1 biomarker measured at Y7...

BACKGROUND: Investigation of anginal chest pain has traditionally involved either assessment of the coronary anatomy by angiography or noninvasive testing for reversible ischemia. Invasive pressure wire assessment at the time of angiography offers information on both anatomy and physiology. Fractional flow reserve-guided percutaneous coronary intervention is associated with lower resource utilization and improved clinical outcome compared with angiographic guidance alone. However, the value of routine fractional flow reserve of all major coronary vessels at the time of diagnostic angiography has not been established in a randomized trial despite persuasive observational data...

Heart failure and related morbidity and mortality are increasing at an alarming rate, in large part, because of increases in aging, obesity, and diabetes mellitus. The clinical outcomes associated with heart failure are considerably worse for patients with diabetes mellitus than for those without diabetes mellitus. In people with diabetes mellitus, the presence of myocardial dysfunction in the absence of overt clinical coronary artery disease, valvular disease, and other conventional cardiovascular risk factors, such as hypertension and dyslipidemia, has led to the descriptive terminology, diabetic cardiomyopathy...
