The present study was conducted on 35 buffalo foetuses from 0.9 cm CVRL (32 days) to 99.5 cm CVRL (298 days) to observe the morphogenesis and histogenesis of heart. The study revealed that, in 0.9 cm CVRL buffalo foetus, heart was unseptated and tubular which was clearly divided into common atrial chamber dorsally, primitive ventricles ventrally, primitive outflow tract with bulbous cordis regi...

X' On opening the chest the right lung was found most prominent and it was covering the heart and extending over to the left side of the chest. The left lung was not evident as the pericardium was full of blood and most of the lower part of the cavity of the left side of the chest was occupied by the pericardium. On opening the pericardium and removing the blood I found that the heart was ruptu...

Acute heart failure due to myocarditis is not common in Takayasu arteritis, let alone in combination with thrombosis affecting both ventricles and pulmonary arteries. The concomitant infection of non-tuberculosis mycobacterium further complicates the clinical scenario and poses challenges for implementation of tailored treatments. This case report describes a teenage girl with a history of inte...

Complex cyanotic congenital heart diseases with left isomerism are sometimes associated with atrioventricular nodal conduction disturbances that may need permanent pacing. Surgical palliation in such anatomy connecting the superior vena cava to the pulmonary artery precludes a transvenous access for an endocardial pacing lead to the ventricles. Epicardial leads in these patients fail if the pac...

Cardiac abnormalities are common. A wide spectrum of lesions can be encountered in the child and fetus. Complex abnormalities are over-represented in prenatal series as these may be more readily recognized during routine anatomical surveys. While the diagnosis of ‘simple’ defects such as pulmonary stenosis or an isolated ventricular septal defect in an otherwise normally connected heart is usua...

BACKGROUND A secondary rise of intracellular Ca(2+) (Cai) and an upregulation of apamin-sensitive K(+) current (I(KAS)) are characteristic findings of failing ventricular myocytes. We hypothesize that apamin, a specific I(KAS) blocker, may induce torsades de pointes (TdP) ventricular arrhythmia from failing ventricles exhibiting secondary rises of Cai. OBJECTIVE To test the hypothesis that sm...

Following contraction of the heart, efficient relaxation (diastole) is essential for refilling the ventricles with blood. This review describes how ventricular relaxation is controlled by Ca(2+) homeostasis in cardiac muscle cells and how alterations in Ca(2+) cycling affect diastolic function in the normal and failing heart. These discussions illustrate that the diastolic phase is not simply a...

Idiopathic dilated cardiomyopathy (DCM) refers to congestive heart failure which is secondary to abnormal functioning of the ventricles (predominantly left) in the absence of congenital, valvular or disease of the coronary artery as well as any other systemic diseases which are thought to cause myocardial dysfunctioning. In children, DCM is one of the most common types of heart muscle disease w...

Dilated cardiomyopathy (DCM) is primary disease of the muscle of the heart, characterized by a progressive decline in the contractility of the ventricles, dilation of all the cardiac chambers, leading to congestive heart failure (CHF), arrhythmias, and death. Histopathology of the cardiac muscle (myocardium) reveals necrosis of cardiac cells, scar tissue (fibrosis), and sometimes replacement of...
