Congenitally corrected transposition of the great arteries (ccTGA) can occur in isolation, or in combination with other structural cardiac anomalies, most commonly ventricular septal defect, pulmonary stenosis and tricuspid valve disease. Clinical recognition can be challenging, so echocardiography is often the means by which definitive diagnosis is made. The tricuspid valve and right ventricle are on the systemic arterial side of the ccTGA circulation, and are therefore subject to progressive functional deterioration...

Women with polycystic ovary syndrome (PCOS) have compromised cardiovascular health profiles and an increased risk of pregnancy complications. In order to evaluate potential consequences, we aim to compare the cardiovascular and metabolic health of the children from women with PCOS with a population-based reference cohort. We included children from women with PCOS between the age of 2.5 to 4 years (n = 42) and 6 to 8 years (n = 32). The reference groups consisted of 168 (3-4 years old) and 130 children (7-8 years old)...

Adipose tissue is an important source of adipose derived stem cells (ADSCs). These cells have the potential of being used for certain therapies, in which the main objective is to recover the function of a tissue/organ affected by a disease. In order to contribute to repair of the tissue, these cells should be able to survive and carry out their functions in unfavorable conditions after being transplanted. This process requires a better understanding of the biology involved: such as the time cells remain in the implant site, how long they stay there, and whether or not they differentiate into host tissue cells...

A previously healthy 2-year-old Guatemalan female with an undiagnosed chronic illness characterized by fever and rash had presented with anorexia, weight loss, periorbital edema, abdominal pain and distention. A chest radiograph documented cardiomegaly. An echocardiogram demonstrated a pericardial effusion, dilated right atrium, right ventricle, and main pulmonary artery as well as diminished right ventricular systolic function and pulmonary hypertension. Right ventricular systolic pressure was estimated at 90 mmHg...

BACKGROUND: It has been difficult to prove that the "catecholamine-induced cardiomyopathy" contributes to the mechanism of sudden cardiac death in Chagas heart disease. Also, it is almost impossible to rule out the possibility that is not involved in the process. More importantly, the vagal-cholinergic pathway in the ventricle plays a direct role in the prevention of the initiation of complex ventricular arrhythmias, including non-sustained ventricular tachycardia, ventricular fibrillation responsible for sudden death...

BACKGROUND: It has been proposed that chronic exposure to prolonged strenuous exercise may result in maladaptation of the right ventricle (RV). The of this study aim was to establish RV structure and function, including septal insertion points, using conventional echocardiography and myocardial strain (ε) imaging in a veteran population of ultramarathon runners (UR) and age- and sex-matched controls. METHODS: A retrospective study design provided 40 UR (>35 years old; mean ± SD training experience, 18 ± 12 years) and 24 sedentary controls who had previously undergone conventional two-dimensional, tissue Doppler and speckle-tracking echocardiography to measure RV size and function...

We present the case of a patient who presented with acute coronary syndrome and was found to have a mass compressing the left atrium. An angiogram revealed a large saphenous vein graft aneurysm with a fistula into a cardiac chamber, presumed to be the left ventricle. The patient also developed a functional mitral stenosis secondary to this mass causing left atrial compression. The patient passed away prior to receiving surgery. We describe a rare case of venous graft aneurysm with compression and fistula to a chamber other than the right atrium, that to our knowledge has yet to be reported...

BACKGROUND: Spinal cord and brain stem lesions require a judicious approach with an optimized trajectory due to a clustering of functions on their surfaces. Intraoperative mapping helps locate function. To confidently locate such lesions, neuronavigation alone lacks the desired accuracy and is of limited use in the spinal cord. OBJECTIVE: To evaluate the clinical value of fluoresceins for initial delineation of such critically located lesions. METHODS: We evaluated fluorescein guidance in the surgical resection of lesions with blood-brain barrier disruption demonstrating contrast enhancement in magnet resonance imaging in the spinal cord and in the brain stem in 3 different patients...

BACKGROUND: In single ventricle patients, aorticopulmonary collaterals (APCs) and pulmonary arteriovenous malformations (PAVMs) following superior cavopulmonary shunt (CPS) can complicate orthotopic heart transplant (OHT) by cyanosis and hemoptysis. Though PAVMs can regress with restoration of hepatic venous flow to the pulmonary circulation, the effects of hypoxemia on the "unconditioned" allograft are not known. CASES: Two patients with significant PAVMs after CPS were cyanotic following OHT...

The Brugada syndrome (BrS) is associated with increased risk of ventricular arrhythmias and sudden cardiac death. It generates genetically mediated arrhythmias posing a true pathophysiological challenge. In search of the similarities between BrS and long QT syndrome some novel insights are suggested. In patients with BrS the duration of QT interval is usually normal. Some investigators have found prolonged QT interval in the syndrome's natural course or the duration of QT segment have been extended by provocative tests unmasking BrS...

OBJECTIVES: Systemic left-to-right shunting causes pulmonary arteriopathy, leading to progressive cardiopulmonary failure and a poor prognosis. In this study, we examined the extraglycemic effect of a synthetic glucagon-like peptide, exendin-4, on pulmonary arteriopathy regression and cardiopulmonary function in nondiabetic rats. METHODS: Pulmonary hypertension (PH) was induced by monocrotaline (60 mg/kg, subcutaneous) injection followed by the creation of an aortocaval fistula...

Intensive training is associated with hemodynamic changes that typically induce an enlargement of cardiac chambers, involving not only the ventricles but also the atria. The hearts of competitive athletes are characterized by increases in left and right atrial dimensions that have been interpreted as a physiologic adaptation to training. Conversely, some authors have hypothesized maladaptive remodeling; furthermore, the extent of left atrial dimensional remodeling may overlap atrial dilation observed in patients with cardiac disease, representing a challenge for clinicians...

BACKGROUND: Intrauterine exposure to a diabetic environment is associated with adverse fetal myocardial remodeling. The aim of this study was to assess the biventricular systolic and diastolic function of fetuses exposed to maternal diabetes (MD) compared with control subjects, using a comprehensive cardiac functional assessment and exploring the role of speckle-tracking to assess myocardial deformation. The authors hypothesized that fetuses exposed to MD present signs of biventricular dysfunction, which can be detected by deformation analysis...

BACKGROUND: Rfx winged-helix transcription factors, best known as key regulators of core ciliogenesis, also play ciliogenesis-independent roles during neural development. Mammalian Rfx4 controls neural tube morphogenesis via both mechanisms. RESULTS: We set out to identify conserved aspects of rfx4 gene function during vertebrate development and to establish a new genetic model in which to analyze these mechanisms further. To this end, we have generated frame-shift alleles in the zebrafish rfx4 locus using CRISPR/Cas9 mutagenesis...

BACKGROUND: Previous studies have suggested the presence of dyssynchrony in the functionally single ventricle. The aim of this study was to investigate the presence of classic-pattern dyssynchrony (CPD), characterized by typical early and late deformation of opposite walls, and its relation to QRS duration and myocardial function in patients with single-ventricle physiology after Fontan palliation. METHODS: In a retrospective cross-sectional study, 101 adolescent and adult patients with single-ventricle physiology after the Fontan procedure were investigated...

OBJECTIVES: Patients with decreased left ventricular function undergoing cardiac surgery have a greater chance of difficult weaning from cardiopulmonary bypass and a poorer clinical outcome. Directly after weaning, interventricular dyssynchrony, paradoxical septal motion, and even temporary bundle-branch block might be observed. In this study, the authors measured arterial dP/dtmax, mean arterial pressure (MAP), and cardiac index using transpulmonary thermodilution, pulse contour analysis, and femoral artery catheter and compared the effects between right ventricular (A-RV) and biventricular (A-BiV) pacing on these parameters...
