REVIEW
Shelby Kutty, David A Danford, Gerhard-Paul Diller, Oktay Tutarel
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...

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...

INTRODUCTION: Ablation in the left ventricle (LV) is associated with a risk of thromboembolism. There are limited data on the use of specific thromboembolic prophylaxis strategies post-ablation. We aimed to evaluate a thromboembolic prophylaxis protocol after ventricular tachycardia (VT) ablation. METHODS AND RESULTS: The index procedures of 217 patients undergoing ablation for infarct-related VT with open irrigated-tip catheters were included. Patients with large LV endocardial ablation area (> 3 cm between ablation lesions) were started on low-dose, slowly escalating unfractionated heparin (UFH) infusion 8 hours after access hemostasis, followed by 3 months of anticoagulation...

BACKGROUND: Partial trisomy is often the result of an unbalanced segregation of a parental balanced translocation. Partial trisomy16q is characterized by a common, yet non-specific group of craniofacial dysmorphic features, and systemic malformations with limited post-natal survival. Most of the cases of partial trisomy 16q described in the scientific literature have reported only one, or less frequently two cardiac defects in the affected babies. Herein, we report a case of partial trisomy 16q21➔qter with multiple and complex cardiac defects that have not previously been reported in association with this condition...

BACKGROUND: Traditional palliation for biventricular cyanotic congenital heart lesions often involves staging with systemic-to-pulmonary arterial shunts to secure pulmonary blood flow (PBF) in the newborn period prior to complete repair. However, shunts may lead to life-threatening events secondary to shunt occlusion or acute coronary steal. They may be associated with morbidity secondary to diastolic runoff, systemic steal and volume loading, and do not provide pulsatile flow which has the potential to promote pulmonary artery (PA) growth...

Factor contributing to the high prevalence of hypertension in the elderly is currently observed high survival rate of people diagnosed and treated hypertension, as well as the aging process itself. Detection of systemic complications was considered to be an important element of the diagnosis of hypertension as well as an important parameter of prognosis. Nowadays, echocardiography is the main tool used to assess heart cavities and to diagnose ventricular hypertrophy. AIM: The aim of the study was echocardiographic evaluation of the heart in the course of hypertension in the elderly...

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...

BACKGROUND: The inflammatory response associated with acute pulmonary embolism (PE) contributes to the development of right ventricular (RV) dysfunction. Nonsteroidal anti-inflammatory drugs (NSAIDs) may facilitate the reversal of PE-associated RV dysfunction. METHODS: We randomly assigned normotensive patients who had acute PE associated with echocardiographic RV dysfunction and normal systemic blood pressure to receive intravenous (IV) diclofenac (two doses of 75mg in the first 24h after diagnosis) or IV placebo...

BACKGROUND/OBJECTIVES: Although echocardiographic-Doppler cardiac index (CI) assessment is widely used to guide heart failure management in patients with biventricular circulation, this application has not been studied in the Fontan population. The objective of this study was to: (1) determine the correlation between Doppler and cardiac catheterization CI calculation; (2) determine the association between Doppler CI and the occurrence of Fontan failure. METHODS: Retrospective review of adult Fontan patients followed at Mayo Clinic Adult Congenital Heart Disease program, 1994-2015...

The diagnosis of cardiac sarcoidosis (CS) has become easier due to advances in imaging modalities, but we sometimes encounter difficult-to-diagnose patients. We herein report the case of a 60-year-old Japanese woman who was diagnosed with isolated CS, although she also met the diagnostic criteria of arrhythmogenic right ventricular cardiomyopathy (ARVC). A histological examination by an endomyocardial biopsy of the right ventricle revealed the typical findings of granulomatous change for CS. Although she did not show any characteristics of systemic sarcoidosis, oral prednisolone treatment was introduced, and she achieved a good response...

Congenital heart defect (CHD) is the most common type of birth defect in humans and a leading cause of infant morbidity and mortality. Previous studies have demonstrated that genetic defects play a pivotal role in the pathogenesis of CHD. However, the genetic basis of CHD remains poorly understood due to substantial genetic heterogeneity. In this study, the coding exons and splicing boundaries of the NR2F2 gene, which encodes a pleiotropic transcription factor required for normal cardiovascular development, were sequenced in 168 unrelated patients with CHD, and a novel mutation (c...

BACKGROUND: NO bioavailability has not been systematically examined in congenital heart disease (CHD). To assess NO in patients with CHD, we measured nasal NO (nNO) generated by the nasal epithelia, given blood NO is difficult to measure (half-life, <2 ms). Given NO's role in hemodynamic regulation and the association of NO bioavailability with heart failure risk, we hypothesized NO levels may differ with varying severity of CHD physiologic characteristics. METHODS AND RESULTS: Six-hundred eighteen subjects, 483 with CHD and 135 controls, had nNO measured noninvasively via the nares using American Thoracic Society/European Respiratory Society guidelines...

The brain of the crocodile is known to gain in mass allometrically throughout life, and the addition of neurons (as well as non-neurons) appears to play a significant role in this increasing brain mass. We used immunohistochemistry in the brains of 12 Nile crocodiles ranging between 350 g and 86 kg in body mass and 1.99 g to 7.9 g in brain mass to identify the regions of the brain in which neurons immunopositive for doublecortin, a marker for potential adult neurogenesis, are found. Similar to other reptiles, potential newly born neurons, those immunopositive for doublecortin, were found throughout the telencephalon, the main and accessory olfactory bulbs and the olfactory tract, and in the cerebellar cortex; however, no doublecortin immunopositive neurons were observed in the diencephalon or brainstem...

The available information about anatomical characteristics of the cardiovascular system of the alpaca (Vicugna pacos, Linnaeus 1758) is scarce. The general objective of this work was to describe its heart anatomy. We dissected six adult animals and five neonates. The heart of the alpaca was located in the middle mediastinum, with a craniocaudal extension from the third to the sixth rib. No ligament that connected the fibrous pericardium to the sternum or to the diaphragm was detected. In the right atrium, there was a developed crista terminalis and small pectinate muscles...

BACKGROUND: Right atrial appendage aneurysms are rare entities that may have significant clinical consequences. When co-existing with atrial fibrillation, patients are at risk of developing pulmonary or paradoxical systemic emboli. CASE PRESENTATION: An elderly patient presented to medical attention with symptoms of acute diverticulitis. On abdominal computed tomography, a massively enlarged right atrial appendage aneurysm was discovered incidentally. The aneurysm caused marked compression of the right ventricle and contained an area of hypoenhancement concerning for an intraluminal thrombus...
