Introduction: In this study, we sought to illustrate our experience in urgent surgical management for embolized cardiac septal occlude devices resulting from trans-catheter closure of atrial septal defect and ventricular septal defect. Mathrials and Methods: We retrospectively reviewed four patients aged 2–10 years who underwent urgent surgery due to cardiac septal occluder embolization between...

Left ventricular function in 53 patients with secundum atrial septal defect was assessed by computer-assisted analysis of the left ventricular echocardiogram and by cardiac catheterization. The patients were divided into two groups, those younger and those older than 60 years, to investigate the effect of aging on left ventricular function. Cavity size was significantly smaller than normal (p l...

Objective(s): The present study was aimed to investigate the influence of thoracic epidural blockade on hypoxia-induced pulmonary hypertension in rats. Materials and Methods: Forty eight Wistar rats were randomly divided into 4 equal groups, named normoxia hypoxia hypoxia/ ropivacaine and hypoxia/saline. Animals were placed in a hypoxia chamber and instrumented with epidural catheters at the t...

BACKGROUND Echocardiographic reference ranges are important to identify abnormalities of cardiac dimensions. Reference ranges for children in sub-Saharan Africa have not been established. The aim of this study was to establish echocardiographic z-score references for Black children in sub-Saharan Africa. METHODS 282 healthy subjects aged 6-16years (143 [51%] males) with no known history of ca...

The echocardiographic findings of eight patients with hypertrophic cardiomyopathy without outflow obstruction (HMC) and of 15 normal (Norm) individuals are presented. The characteristic features in HMC were: (1) interventricular septal width much greater than normal (HMC= 2.5 + 0.3 cm, Norm = 1.0 + 0.2 cm, P <0.005); (2) normal or only slightly increased posterior left ventricular wall thicknes...

To determine whether chronic pressure overload and hypertrophy of the right ventricle alter the diastolic properties of the left ventricle, six adult dogs underwent banding of the pulmonary artery and were instrumented for studies 8 months later. Fourteen control dogs were also studied. Pressure and dimension data were collected from the dogs while they were awake and unsedated. The anterior-po...

Filtered bipolar catheter electodes, I mm apart, were used to pace and record from the high right atrium, right ventricular apex, right ventricular outflow tract, right ventricular inflow tract, middle cardiac vein, great cardiac vein, and endocardium of the left ventricular septal surface. Right ventricular apex to middle cardiac vein and the middle cardiac vein to right ventricular apex condu...

holt-oram syndrome is an autosomal dominant disorder, characterised by skeletal abnormalities of the upper limb associated with congenital heart defect, mainly atrial and ventricular septal defects. skeletal defects exclusively affect the upper limbs in the preaxial radial ray distribution and are bilateral and asymmetrical. they range from clinodactyly, absent or digitalised thumb, hypoplastic...

Aortic valve atresia is usually associated with hypoplasia of the left ventricle and mitral valve. We report a patient presenting aortic atresia with ventricular septal defect and a normally sized left ventricle. The electrocardiogram showed left axis deviation and left ventricular hypertrophy. The ventricular septal defect probably favored a normal growth of the left ventricle, allowing it to ...

To assess regional contractility in idiopathic hypertrophic subaortic stenosis (IHSS), a primary myopathic disorder with documented hyperdynamic ventricular contractions, systolic wall thickening and velocity of contraction of the septum and left ventricular posterior wall were measured in echocardiograms from 16 patients with IHSS and 16 normal subjects. The average thickening of the normal se...
