Mutations leading to disorders within ion (mainly potassium and sodium) channels, have different degrees of expression in the brain and in the heart, which can cause simultaneous occurrence of disorders in both organs. This is manifested by the occurrence of epileptic seizures and cardiac electrical disturbances, further exacerbated by stimulation of autonomic structures within the central nervous system. In all patients with unclear paroxysmal disorders, and in those with unexplained sudden cardiac death, consideration should be given to the possibility of occurrence of genetically determined disorders in the ion channels...

Several expert documents on sex-based differences in interventional outcomes are now available, however this is the first position paper from the EAPCI Women Committee discussing the potential influence of sex in the percutaneous treatment of coronary and structural heart disease. Despite the misconception that coronary artery disease is a 'man's disease', contemporary data shows a growing incidence in women. However, women are under-represented in randomised coronary clinical trials (~25%). The generalisation of such studies is therefore problematic in decision-making for females undergoing coronary intervention...

Angiotensin-converting enzyme (ACE-I) inhibitors and ARBs have shown real efficacy in reducing blood pressure, proteinuria, in slowing the progression of chronic kidney disease (MRC) and in clinical improvement. in patients with heart failure, diabetes mellitus and ischemic heart disease. However, their use is limited by some side effects such as the increase in serum potassium (K), which can be particularly severe in patients with renal insufficiency. In the 23,000 patients followed by the PIRP project of the Emilia-Romagna Region, hyperkalaemia at the first visit (K> 5...

The indications for catheter-based structural and electrophysiological procedures have recently expanded to more complex scenarios, in which an accurate definition of the variable individual cardiac anatomy is key to obtain optimal results. Intracardiac echocardiography (ICE) is a unique imaging modality able to provide high-resolution real-time visualization of cardiac structures, continuous monitoring of catheter location within the heart, and early recognition of procedural complications, such as pericardial effusion or thrombus formation...

RATIONALE & OBJECTIVE: Abnormal cardiac structure and function are common in chronic kidney disease (CKD) and end-stage renal disease (ESRD) and linked with mortality and heart failure. We examined changes in echocardiographic measures during the transition from CKD to ESRD and their associations with post-ESRD mortality. STUDY DESIGN: Prospective study. SETTING & PARTICIPANTS: We studied 417 participants with CKD in the Chronic Renal Insufficiency Cohort (CRIC) who had research echocardiograms during CKD and ESRD...

Normal pediatric values of three-dimensional (3D) left ventricular (LV) volumes and strain are not well established; moreover, no reports exist of the stress-strain relation and the heart rate-corrected velocity of circumferential fiber shortening (VCFc) based upon 3D imaging in children. Three-dimensional LV datasets were obtained in pediatric patients (≤18 years of age) with structurally normal hearts. Ventricular volumes and strain components (longitudinal, GLS; circumferential, GCS; and 3D strain, 3DS) were analyzed using a commercial 3D speckle-tracking analysis package...

Long QT syndrome (LQT) represents a heterogeneous family of cardiac electrophysiologic disorders characterized by QT prolongation and T-wave abnormalities on the electrocardiogram. It is commonly associated with syncope, however, sudden cardiac death can occur due to torsades de pointes. LQT is a clinical diagnosis and should be suspected in individuals on the basis of clinical presentation, family history and electrocardiogram characteristics. Management is focused on the prevention of syncope and ultimately sudden death...

Two new flavonoid-triterpene saponin meroterpenoids, clinoposides G (1) and H (2) were isolated from the aerial parts of Clinopodium chinense (Benth.) O. Kuntze. Their structures were elucidated through spectroscopic and electronic circular dichroism (ECD) analyses. Compounds 1 and 2 were evaluated for their protective effects against anoxia/reoxygenation(A/R)-induced injury in H9c2 cells. A/R treatment severely injured the H9c2 cells, which was accompanied by apoptosis. Both 1 and 2 pretreatment significantly inhibited cell injury and apoptosis, improved mitochondrial membrane potential, increased activities of antioxidant enzymes, and reduced the levels of the inflammatory cytokines...

Congenital heart defects (CHDs) are the most common cause of childhood morbidity and early mortality. Prenatal detection of the underlying molecular mechanisms of CHDs is crucial for inventing new preventive and therapeutic strategies. Mutant mouse models are powerful tools to discover new mechanisms and environmental stress modifiers that drive cardiac development and their potential alteration in CHDs. However, efforts to establish the causality of these putative contributors have been limited to histological and molecular studies in non-survival animal experiments, in which monitoring the key physiological and hemodynamic parameters is often absent...

PURPOSE OF REVIEW: Patients with chronic kidney disease (CKD) are at a high risk for cardiovascular events and mortality, particularly heart failure. Echocardiography is the most commonly used diagnostic imaging modality for heart failure. The purpose of this review is to summarize recent literature that demonstrates how echocardiography may be used to define cardiac structure and function in the CKD population and to identify echocardiographic abnormalities that have utility in predicting clinical outcomes in this population...

Endocarditis (IE) is defined by an infection of a native or prosthetic heart valve, the mural endocardium, or an indwelling cardiac device. Although viridan-group streptococci (VGS) and Staphylococci species have collectively been considered as the most common cause of endocarditis, uncommon pathogens may also lead to the disease with significant morbidity and mortality. Abiotrophia defectiva , a nutritionally variant streptococci (NVS), is a virulent bacterium that preferentially affects endovascular structure and is implicated in many culture-negative endocarditis with dreadful complications such as heart failure, septic embolization, and valve destruction...

Formation of tumor thrombus is an occasional manifestation of renal cell carcinoma (RCC). Intravascular invasion of the renal vein and thereafter the inferior vena cava (IVC) might in very rare cases extend into the cardiac chambers. The subtle course and symptoms of such cases alongside with the engagement of vital anatomical structures marks them as a diagnostic and therapeutic challenge. Aggressive surgical intervention has proven to be critical for survival rates in such cases; however total synchronous resection remains a challenge for the surgical team and a debate for the medical community...

Diabetes affects cardiac structure and function, where it leads to diabetic cardiomyopathy. Reactive oxygen species (ROS) produced by oxidative stress play an important role in the development of diabetic cardiomyopathy. Fibroblast growth factor (FGF) 19, an enterokine, is synthesized and released into the ileum. In the present study, we revealed that FGF19 induced an antioxidant response through stimulating the expression of nuclear erythroid factor 2 (NE-F2)-related factor 2 (Nrf2) and as well as reducing ROS production through the AMPK signaling pathway...

BACKGROUND: Normal electrocardiographic (ECG) results have been reported to be associated with a low prevalence of structural heart disease and thus may preclude the need for transthoracic echocardiographic (TTE) imaging. The goal of this study was to determine the prevalence of important TTE abnormalities in patients with a normal ECG referred for TTE imaging. METHODS: Consecutive electrocardiograms over 6 months were reviewed. Patients with a normal ECG who underwent TTE imaging within 30 days formed the study group...

For the year 2017, more than 21,000 published references can be found in PubMed when entering the search term "cardiac surgery". This review focusses on conventional cardiac surgery, considering the new interventional techniques only if they were directly compared to classic techniques but also entails aspects of perioperative intensive care management. The publications last year provided a plethora of new and interesting information that helped to quantify classic surgical treatment effects and provided new guidelines for the management of structural heart disease, which made comparisons to interventional techniques easier...
