Pericardiectomy is the standard treatment in patients with chronic constrictive pericarditis who have persistent symptoms. However, myocardial atrophy with prolonged pericardial constriction and abrupt increase in venous return can lead to heart failure with volume overload after pericardial decompression, especially in the right ventricle (RV). We experienced a 44 year old male patient who dev...

BACKGROUND The right ventricle (RV) has been defined as the "forgotten chamber", as its role in cardiac physiopathology has long been underestimated. Nevertheless, the RV is involved in a wide range of pathological conditions and its altered function may significantly affect the patient's clinical status. METHODS A selection of the most common cardiovascular magnetic resonance (CMR) features ...

Right ventricular (RV) structure and function serve as important indicators of a wide spectrum of heart diseases such as congenital heart disease, pulmonary hypertension, hypertro-phic cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy/disease (ARVC/D) [1–3]. Over the past years cardiac magnetic resonance imaging (CMR) has proven itself as the preferred imaging modality of choic...

Ventricular non-compaction or spongy myocardium is a rare type of cardiomyopathy resulting from arrested myocardial development during embryogenesis. This rare entity is characterized by excessive prominent trabeculations and deep inter-trabecular recesses in the ventricular wall. The clinical manifestations include heart failure, arrhythmias and cardioembolic events. The usual site of involvem...

Almost 3 quarters of a century ago, an experimental dog model, involving the electrocautery ablation of the free wall of the right ventricle (RV), served as the basis for the contention that the RV serves functionally as a passive conduit. Clearly, our understanding of the RV has evolved over subsequent decades, and the prognostic significance of RV dysfunction is now recognized in a wide array...

OBJECTIVES To assess cardiac morphology and function by means of echocardiograms of children with obstructed breathing while asleep. METHODS The study enrolled 40 children of both sexes, aged from 3 to 11 years; 30 of them had obstructed breathing during sleep (group I) and 10 children were healthy controls (group II). The two groups were similar in terms of sex, age, weight and height. The 4...

Transthoracic echocardiography apical four-chamber view reveals a leaflet (Panel E, arrow) and a discrete subaortic membrane between baseline portion of the left ventricle, RA: right atrium, RV: right ...

Noncompaction ventricular myocardium is an unusual cause of cardiomyopathy. It is association with congenital heart defects, most often with outflow obstructive lesions or coronary anomalies. However, no factor could explain the arrest of development of myocardial structure (isolated form). The pathogenesis of isolated noncompaction is thought to be an arrest in endomyocardial morphogenesis. It...

This study investigated the effects of coenzyme Q10 (CoQ10) supplementation on hematological, enzymes activities and biochemical parameters in broilers with pulmonary hypertension syndrome (PHS).Two hundred and forty 1-d-old Ross 308 male broiler chicks were randomly allocated into 3 groups with 4 replicates. From d 14, the diets were supplemented with CoQ10 at levels of 0, 20 and 40 mg/kg, res...

The total heart volume variation (THVV) during systole has been proposed to be caused by radial function of the ventricles, but definitive data for both ventricles have not been presented. Furthermore, the right ventricle (RV) has been suggested to have a greater longitudinal pumping component than the left ventricle (LV). Therefore, we aimed to compare the stroke volume (SV) generated by radia...
