BACKGROUND Ectopia Cordis is defined as complete or partial displacement of the heart outside the thoracic cavity. It is a rare congenital defect with failure of fusion of the sternum with extra thoracic location of the heart. The estimated prevalence of this case is 5.5 to 7.9 per million live births. CASE PRESENTATION We had a case of a 16-hour-old male neonate weighing 2.9kg with externall...
A survey conducted by cardiologists in Soweto, Johannesburg, provided an opportunity of assessing the frequency of congenital heart disease in black schoolchildren. Among 12,050 schoolchildren aged 2 to 18 years, 48 had a congenital heart defect, yielding a prevalence of 3.9 per 1000. Only in 2- to 6-year-old children did the prevalence exceed that of rheumatic heart disease. The distribution o...
Background. The congenitally corrected transposition of the great arteries (L-TGA) is a very rare congenital heart defect, which often remains undetected for several decades of life. Case Presentation. We report on a 45-year-old man without prior history of heart disease, presenting with cardiac shock related to a first episode of tachycardic atrial fibrillation. The diagnostic work-up identifi...
Objective- To evaluate tail vertebra as an autogenous cortical bone and cancellous bone for filling ulnarsegmental bone defect in dogs.Design- Experimental study.Animals- Eight adult mongrel dogs with an aver age age of 37.S months and average body wei ght of17.62 kg.Procedure- Th e animals were randomly divided into two groups . A bone defect (2.S-cm) was created onthe middle po rtion of the r...
Background & Aim: Coarctation accounts for about 5-9% of congenital heart diseases and is the fifth common congenital heart disorder in children. Approximately 90% of untreated patients die before the age of 50 and about half of deaths occur before the age of 10 due to heart failure. The main goal of this study is assessing the frequency of reccurent coarctation after repair and determining...
Objective(s): In heart failure, the heart-to-mediastinum (H/M) ratio of the delayed image and washout rate (WR) are well-known as a powerful cardiac event predictors. H/M ratio quantifies the accumulation rate of MIBG in the myocardium and WR quantifies reduction of meta-iodobenzylguanidine (MIBG) accumulation in the heart from the early planar image to the delayed pla...
BACKGROUND AND AIM In Congenital Heart Disease (CHD), shunting of blood occurs through the anatomical defects which lead to mixing of oxygenated and deoxygenated blood. Chronic hypoxia which occurs due to the above said mechanism has the potency to cause DNA damage in children with CHD. In chronic hypoxia, there is a liberation of Reactive Oxygen Species (ROS) due to tissue injury as a result o...
background: closure of patent ductus arteriosus (pda), ventricular septal defect (vsd) and atrial septal defect (asd) can be done surgically or by device. this study was designed to compare the total cost of surgical or device closures of pda, asd or vsd for iranian patients. methods: this is a cross-sectional study, conducted from january 1, 2005 until january 1, 2006 in two large heart center...
The haemodynamic effects and clinical manifestations of congenital heart lesions may be greatly influenced by developmental changes in the circulation. The sequential changes associated with abnormal communications between the systemic and pulmonary circulations are well typified by the effect on ventricular septal defect. The possible influences of ventricular septal defect on the foetal circu...
INTRODUCTION Aortopulmonary window (APW), a large aortopulmonary septal defect (APSD), is a serious and rare defect within congenital heart diseases. CASE REPORT In this study, we reported an APW case with severe pulmonary arterial hypertension. This patient was successfully treated by transcatheter closure with a muscular ventricular septal defect (VSD) occluder. CONCLUSION We had a succes...
