In most cases, the clinical importance of fetal isolated mild tricuspid valve regurgitation is not known. This study evaluated the relationship between fetal isolated mild tricuspid regurgitation in the general obstetric population and postnatal congenital cardiac disorders. Detailed fetal echocardiography was done between 18 and 24 weeks' gestation to detect ...

For individuals and the society as a whole, the increased risk of sudden cardiac death in obese patients is becoming a major challenge, especially since obesity prevalence has been increasing steadily around the globe. Traditional risk factors and obesity often coexist. Hypertension, diabetes, obstructive sleep apnea and metabolic syndrome are ...

Abstract Atrial fibrillation (AF) is a highly prevalent arrhythmia with pronounced morbidity and mortality. Genetics analysis has established electrophysiological substrates, which determine individual vulnerability to AF occurrence and maintenance. MicroRNAs (miRNAs) found in virtually all organisms function as negative regulators of protein-coding genes. Several studies have suggested a role for ...

Atrial fibrillation (AF) represents the most common cardiac arrhythmia and chronic oral anticoagulation (OAC) is the cornerstone therapy to prevent cerebrovascular events among those having high thromboembolic risk. However, 20-30% of patients with AF have co-existing coronary artery disease (CAD). Importantly, since the prevalence of both AF and CAD increase ...

The management of cardiac arrest after cardiac surgery differs from the management of cardiac arrest under other circumstances. In other studies, interposed abdominal compression-cardiopulmonary resuscitation (IAC-CPR) resulted in a better outcome compared with conventional CPR. The aim of the present study was to determine the feasibility, safety and efficacy of ...

Midkine (MK), a heparin-binding growth factor, has been shown to prevent cardiac remodeling after ischemic injury through its anti-apoptotic effect. Cell apoptosis is central to the pathophysiology of cardiac remodeling in congestive heart failure (CHF) of ischemic as well as non-ischemic origin. We hypothesized that MK exerts the anti-apoptotic cardioprotective ...

Resuscitation of patients who sustain a cardiac arrest as a result of trauma (traumatic cardiac arrest) has previously been described as 'futile'. Several published series have since contradicted this claim and reported survival-to-discharge data ranging from 0 to 35%. International resuscitation guidelines (European Resuscitation Council and American Heart Association) promote ...

Cardiac resynchronization therapy (CRT) is a well-established therapy for patients with heart failure (HF) and wide QRS configuration, especially for those in sinus rhythm. However, for those with permanent AF, atrioventricular nodal (AVN) ablation use remains under debate. Our objective was to evaluate clinical outcomes and mortality of AVN ablation ...

Because of heart-lung interactions, weaning from mechanical ventilation induces strong hemodynamic changes that can lead to weaning-induced cardiac failure. Cardiac patients are particularly at risk for this complication. In this review, we will summarize the most recent advances concerning the mechanisms, diagnosis and treatment of weaning-induced cardiac failure. The role ...

Transesophageal echocardiography (TEE) is often performed during cardiac operations. The need to repeat TEE to exclude left atrial or left atrial appendage thrombus before direct current cardioversion (DCCV) in patients with a recent intraoperative TEE showing no thrombus is unclear. We sought to determine the incidence of and risk factors ...

Ultrasound has been shown to produce Premature Ventricular Contractions (PVC's). Two clinical applications in which acute cardiac pacing by ultrasound may be valuable are: (1) preoperative patient screening in cardiac resynchronization therapy surgery; (2) Emergency life support, following an event of sudden death, caused by cardiac arrest. Yet, previously the ...

Left-bundle-branch-block(LBBB) and QT-prolongation are both associated with a worse prognosis. LBBB lengthens the QT-interval. So far it is not known if QT-time prolongation during LBBB differs in repolarization from QT-time prolongation during narrow QRS. The aim of the present proof-of-concept-study is therefore to develop a formula that allows to compare ...

Background. In organophosphate (OP) poisoning cardiac complications may occur. However, the current body of knowledge largely consists of limited studies, and case reports are mainly on electrocardiogram (ECG) abnormalities. As definite myocardial injury is difficult to assess through ECG, we investigated the prevalence of myocardial injury through cardiac biochemical markers ...

Many advances have been made in the diagnosis and management of heart failure (HF) in recent years. Cardiac biomarkers are an essential tool for clinicians: point of care B-type natriuretic peptide (BNP) and its N-terminal counterpart (NT-proBNP) levels help distinguish cardiac from non-cardiac causes of dyspnea and are also useful ...

Toll-like receptor-4 (TLR4), a receptor of the innate immune system, is suggested to have detrimental effects on cardiac function after myocardial infarction (MI). RP105 (CD180) is a TLR4 homolog lacking the intracellular signaling domain that competitively inhibits TLR4-signaling. Thus, we hypothesized that RP105 deficiency, by amplifying TLR4 signaling, would lead ...

Cardiac resynchronization therapy (CRT) on patients with advanced and refractory heart failure has made remarkable progress. Clinically, notched QRS (nQRS) is commonly seen on electrocardiographs (ECGs) with bundle branch block morphology and on paced ECGs after implantation of a CRT device, which may reflect the heterogeneity of ventricular myocardial depolarization ...

Acute carbon monoxide (CO) poisoning is the most common cause of poisoning and poisoning-related death in the United States. It manifests as broad spectrum of symptoms ranging from mild headache, nausea, and fatigue to dizziness, syncope, coma, seizures resulting in cardiovascular collapse, respiratory failure, and death. Cardiovascular complications of CO ...

Abstract Aluminium phosphide (AlP) is a highly toxic pesticide that inhibits cytochrome oxidase c and causes oxidative stress. Death results from refractory cardiogenic shock due to myocardial dysfunction. There is very little information regarding extracorporeal life support in severe AlP poisoning. Although several therapies are available, none are curative. We ...

Chronic hypersecretion of the pancreatic hormone amylin is common in humans with obesity or prediabetic insulin resistance and induces amylin aggregation and proteotoxicity in the pancreas. We recently showed that hyperamylinemia also affects the cardiovascular system. Here, we investigated whether amylin aggregates interact directly with cardiac myocytes and whether controlling ...

Introduction: Carbon monoxide (CO) is one of the leading causes of poisoning; it inhibits oxygen delivery, subsequently causing ischemic changes and ultimately death by multiorgan failure. Furthermore, thromboembolic episodes due to CO poisoning have been reported. However, intracardiac thrombus formation following exposure to CO has been very rarely described. Here, ...

The no-reflow phenomenon (NRP) is defined as the lack of adequate myocardial tissue perfusion despite a patent epicardial coronary artery. The incidence of NRP varies between 2-5% of elective percutaneous coronary interventions (PCI) and 30% in primary PCI. Clinically, it is an independent predictor of myocardial infarction, in-hospital mortality, and ...
