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 ...

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 ...

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 ...

Carbon monoxide (CO) poisoning frequently affects repolarization, resulting in abnormal electrocardiography findings. The goal of this study was to examine the effect of CO poisoning on the novel transmyocardial repolarization parameters T peak-T end (Tp-e), Tp-e dispersion, and Tp-e/QT and the relationship of these parameters to myocardial injury (MI). This ...

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 ...

We previously reported that type VI collagen deposition increases in the infarcted myocardium in vivo. To date, a specific role for this nonfibrillar collagen has not been explored in the setting of myocardial infarction (MI). To determine whether deletion of type VI collagen in an in vivo model of post-MI ...

Left ventricular noncompaction is an unusual but increasingly recognized cardiomyopathy, the etiology of which is still not definitely established. Clinical presentation includes a wide spectrum of scenarios, including heart failure, thromboembolism and malignant arrhythmias, with half of deaths occurring suddenly. Early detection of LVNC is therefore essential to prevent sudden ...

There is no 'gold standard' non-invasive test to diagnose myocarditis. It is a clinico-histopathological diagnosis.1 Clinical manifestations include: heart failure, chest pain (from either pericarditis or angina from coronary artery spasm/inf lammation), sudden cardiac death and arrhythmias (sinus tachycardia, ectopics, ventricular tachycardia, heart blocks). Examination may reveal raised JVP, pulmonary ...
