OBJECTIVE: During the course of chronic obstructive pulmonary disease (COPD), pulmonary hypertension (PH) and right ventricular (RV) failure may develop due to elevated afterload of the RV. In those patients, exercise capacity is reduced due to pulmonary and cardiac limitations. We investigated relationships between serum N-terminal of proB-type natriuretic peptide (NT-proBNP) and RV functions with exercise capacity and quality of life in patients COPD. METHODS: An observational case-control study was conducted...

A 59-year-old man was admitted for evaluation of short of breath and bilateral leg edema that had progressively worsened over 3 months. Chest computed tomography revealed marked pericardial thickening. Cardiac echocardiography revealed right heart volume load and diastolic dysfunction. Cardiac catheterization revealed a dip-and-plateau pattern of the pressure curve of right ventricule (RV)without any coronary disease. On a diagnosis of heart failure due to pericardial constriction, he underwent pericardiectomy under cardiopulmonary bypass...

In the recent years, the Fontan completion rate for hypoplastic left heart syndrome (HLHS) is improved because of the outcome of stage-1 palliation improved. However, there are still problems to be solved to achieve better hemodynamics after Fontan operation in patients with HLHS. The 2 major commandments other than classic 10 commandments are A:"good ventricular function" and B:"low pulmonary vascular resistance". To obtain these 2, the following problems should be rectified. They include residual arch obstruction, impaired right ventricule (RV) function, tricuspid regurgitation, elevated pulmonary vascular resistance, development of aorto-pulmonary collaterals and etc...

SSc-associated pulmonary arterial hypertension (PAH) has a poorer prognosis than that of other types of pulmonary hypertension. Recent echocardiographic and haemodynamic studies suggest that right ventriculer (RV) pump function and filling characteristics are altered in SSc-PAH as compared with idiopathic PAH. This could be explained by intrinsic myocardial involvement of the disease, related to abnormal collagen deposition, also observed in the left ventricle, or an increased vulnerability to ischaemia due to coronary vasculopathy, abnormal collagen cross-linking and altered myocyte function...

Acrocallosal Syndrome is a rare genetic disorder which is characterized by moderate to severe mental retardation, agenesis or hypoplasia of the corpus callosum and polydactyly of fingers and toes. The spectrum of this syndrome is very variable. Prominent forehead, broad nasal bridge, short nose and mandible, hypertelorism, epicanthic folds, large anterior fontanelle and tapered fingers, omphalocele and inguinal hernia are some other common findings in this syndrome. Twenty percent of the patients have associated brain abnormalities such as cerebral atrophy, hypothalamic dysfunction, small cerebrum, micropolygyria, hypoplasia of pons, hypoplasia of cerebellar hemispheres, hypoplasia of medulla oblongata, agenesis or hypoplasia of cerebellar vermis and corpus callosum abnormalities...

INTRODUCTION: The different non-invasive examinations do not result in unambigous results about the long-term determination of right ventricular function providing systemic circulation in children with transposition of the great arteries operated with Senning procedure. AIM: The goal of study was to determine the application of MRI for the observation of right and left ventricular morphology and function, for the recognition of the progression of the disease, and for the necessity of reoperation...

Regional suppurative meningoencephalitis and ventriculitis of variable chronicity was diagnosed in three young dogs residing in Colorado. Grass awns were grossly identified in the right occipital cortex of one dog and in the right lateral ventricle of another. Intralesional plant material was microscopically evident in the dura mater overlying the right occipital cortex of the third dog. One grass awn was identified as a floret of Hordeum jabatum. In each case, aerobic culture of brain tissue identified multiple isolates of bacteria...

OBJECTIVE: The arterial switch operation has become the procedure of choice for the simple transposition of the great arteries (TGA) while in the complex forms of the defect the staged approach is frequently implemented. The aim of this study is to compare groups of patients with simple transposition and children with the complex form of the defect and identify factors affecting early and late outcome. DESIGN: From 1997 to 2003, 135 consecutive neonates with TGA underwent arterial switch operation and simultaneous reparation of all associated defects...

OBJECTIVE: 'Classical' repair of Ebstein's anomaly is usually performed with transverse plication of the atrialized chamber. However, the anterior leaflet has restricted motion which is an important factor of the tricuspid valve insufficiency. We studied the long term results of mobilization of the anterior leaflet associated with longitudinal plication of the right ventricule. METHODS: From 1980 to July 2002, 191 patients (mean age 24.4+/-15 years (1-65)) were operated on...

47 patients aged from 2 to 59 years affected by valvular congenital or mixed pulmonary stenosis including three fallot trilogies and one patient with right congestive cardiac failure are treated by percutaneous pulmonary valvulotomy between october 1986 and december 1990. All patients have been controlled with a mean follow-up of 6.5 +/- 1.1 years. The total gradient rate between pulmonary artery and right ventricule decrease from 112 +/- 55 mm Hg to 20 +/- 8 mm Hg on the last control with disappearance of infundibular inflammation and inter auricular shunt in all the concerned cases...

OBJECTIVE: To assess cardiac beta-adrenoceptors (beta-AR) in an obesity-hypertension model. METHODS: Six male beagle dogs (aged 35 +/- 5 months) receiving during 30 weeks a high-fat diet with 60% uncooked beef fat were compared to 6 normal beagle dogs. With right auricular and left ventricular samples we analysed cardiac beta-AR density through binding study using [125I]-cyanopindolol. beta 1 and beta 2 densities were obtained by competition with CGP 20712A. Affinity state of beta-AR was assessed by competition with isoproterenol...

After a Senning procedure for transposition of the great arteries (TGA), systolic dysfunction of the right ventricle (RV) is common. Pre and peroperative chronicale hypoxia may be the cause of this ventricular myocardial alteration. In order to detect abnormalities of myocardial viability and to study their relationship to RV function, the authors studied 41 patients (pts), 11.3 +/- 3 years after a Senning procedure. All patients underwent myocardial scintigraphy of the RV under basal conditions. 1 hour after injection of 1...

A novel operative technique for postinfarction ventricular septal defect has been used in 44 consecutive patients. The operation consists of excluding rather than excising the infarcted septum and ventricular walls. This is accomplished by performance of a left ventriculotomy through the infarcted muscle and securing a glutaraldehyde-fixed bovine pericardium patch to the endocardium of the left ventricle all around the infarcted myocardium. The ventriculotomy is simply closed over the pericardial patch. There were 21 men and 23 women whose mean age was 69 +/- 7 years...

The methods used in the early diagnosis of catheter malposition are compared in 31 patients with temporary endovenous pacemaker. In all cases the heart and the pericardial space were observed either at surgery or at post-mortem examination. The patients were divided into three groups: Group A: eight patients with proof of perforation of the free wall of the right ventricule. Group B: eight patients with dislodgement of the catheter and dysfunction of demand and stimulation without signs of perforation. Group C: fifteen patients without neither dysfunction or perforation...

Hypereosinophilic syndromes are characterized by very high levels of eosinophils in peripheral blood and a dysfunction of several organs as a consequence of their massive infiltration by eosinophilic cells. Cardiac alterations are traditionally known as fibroplastic endomyocarditis (Loeffler's Syndrome). We present the case of a female patient admitted in another center for the study of an accidentally discovered eosinophilia and referred to us because of her progressive hemodynamic deterioration followed by a poor clinical evolution...
