Cardiac rhabdomyoma, a type of benign myocardial tumor, is regarded as the most common fetal cardiac tumor. Rhabdomyomas are usually found before birth or during the first year of life. It is widely accepted that rhabdomyomas are strongly associated with tuberous sclerosis, and tend to regress spontaneously without surgical excision. However, if the tumor has caused significant obstruction or refractory arrhythmias, the surgery should be advocated. Most of the surgeries for pediatric cardiac tumors are performed under cardiopulmonary bypass (CPB) with cardioplegia...

BACKGROUND: Quality of life is as important as survival in heart failure (HF) patients. Controversies exist with regards to echocardiographic determinants of exercise capacity in HF, particularly in patients with preserved ejection fraction (HFpEF). The aim of this study was to prospectively examine echocardiographic parameters that correlate and predict functional exercise capacity assessed by 6 min walk test (6-MWT) in patients with HFpEF. METHODS: In 111 HF patients (mean age 63 ± 10 years, 47% female), an echo-Doppler study and a 6-MWT were performed in the same day...

Cardiac arrest survival rates have improved with modern resuscitation techniques, but many survivors experience impairments associated with hypoxic-ischemic brain injury. Currently, little is understood about chronic changes in striatal dopamine (DA) systems after hypoxic-ischemic brain injury. Given the common empiric clinical use of DA enhancing agents in neurorehabilitation, investigation evaluating dopaminergic alterations after cardiac arrest (CA) is necessary to optimize rehabilitation approaches. We hypothesized that striatal DA neurotransmission would be altered chronically after ventricular fibrillation cardiac arrest (VF-CA)...

We studied the morphology of the atrioventricular conduction system (AVCS) and Purkinje fibers of the yak. Light and transmission electron microscopy were used to study the histological features of AVCS. The distributional characteristics of the His-bundle, the left bundle branch (LBB), right bundle branch (RBB), and Purkinje fiber network of yak hearts were examined using gross dissection, ink injection, and ABS casting. The results showed that the atrioventricular node (AVN) of yak located in the right side of interatrial septum and had a flattened ovoid shape...

Stimulation of β-adrenergic receptors (βAR) provides the most efficient physiological mechanism to enhance contraction and relaxation of the heart. Activation of βAR allows rapid enhancement of myocardial function in order to fuel the muscles for running and fighting in a fight-or-flight response. Likewise, βAR get activated during cardiovascular disease in an attempt to counteract the restrictions of cardiac output. However, long-term stimulation of βAR increases the likelihood of cardiac arrhythmias, adverse ventricular remodelling, decline of cardiac performance and premature death, thereby limiting the use of βAR agonists in the treatment of heart failure...

Maternal nutrient restriction induces IUGR increasing later life chronic disease including cardiovascular dysfunction. Our left ventricular (LV) CMRI studies in IUGR baboons (8 M, 8 F, 5.7 years- human equivalent approximately 25 years), control offspring (8 M, 8 F, 5.6 years), and normal elderly (OLD) baboons (6 M, 6 F, mean 15.9 years) revealed long-term LV abnormalities in IUGR offspring. Although it is known that right ventricular (RV) function is dependent on LV health, the IUGR right ventricle (RV) remains poorly studied...

Increased survival rates after corrective or palliative surgery for complex congenital heart disease (CHD) in infancy and childhood are now being coupled with increased numbers of patients who survive to adulthood with various residual lesions or sequelae. These patients are likely to deteriorate in cardiac function or end-organ function, eventually requiring lifesaving treatment including heart transplantation. Although early and late outcomes of heart transplantation have been improving for adult survivors of CHD, outcomes and pretransplant management could still be improved...

We report 5 cases of acute heart failure (AHF) related to multiple sclerosis (MS) relapses. AHF was inaugural in 3 patients, always preceded or accompanied by signs of brainstem dysfunction; it was severe, requiring intensive care management. Echocardiography showed left ventricular hypokinesis. No other cause of AHF has been found. All patients showed a new medullary lesion on brain MRI. All had rapid and complete recovery of ventricular function after intravenous corticosteroids. We concluded to a takotsubo phenomenon...

INTRODUCTION: Because of parallel circulation in the fetus and the differential effect various disease states may have on the shape of the right and left ventricles, this study was conducted to evaluate the Sphericity Index (SI) of 24 transverse segments distributed from the base to the apex of the ventricular chambers. METHODS: Two hundred control fetuses were examined between 20 and 40 weeks of gestation. The displacement of the ventricular endocardium during the cardiac cycle was computed using offline software...

Patients with Brugada syndrome are at risk of life threatening ventricular arrhythmias. Epicardial substrate ablation for Brugada syndrome has been described as a means of controlling these arrhythmias and recent reports describe elimination of the Brugada phenotype with ablation. We describe a unique case in which a patient developed inferior J waves with an early repolarization-type electrocardiogram following successful epicardial infundibular substrate ablation (which eliminated the Brugada syndrome ECG on ajmaline challenge)...

BACKGROUND: Atrial undersensing despite normal atrial lead parameters and high amplitude electrograms has been described in adult patients as a consequence of atrial amplifier saturation. Repetitive inputs cause amplifier ringing and undersensing occurs as consequence of quiet timer blanking. High amplitude ventricular electrograms can also result in atrial blanking secondary to cross chamber effect. This has not been described in pediatric patients or epicardial pacing systems and specific risk factors are not known...

PURPOSE: Increased left ventricular mass (LVM) is an early precursor of target organ damage due to hypertension. Diminished parasympathetic cardiac control has been linked to both hypertension onset and left ventricular impairment; however, emerging evidence suggests that this pattern may be different in African Americans. The present study sought to determine if race impacts the relationship between parasympathetic cardiac control and LVM. METHODS: LVM was assessed via echocardiography in a sample (N = 148) of African American and White adults (Mean age = 33...
