PURPOSE: To determine the value of dual-source computed tomography (DSCT) in depicting the morphological characteristics and diagnosing the associated malformations for patients with transposition of the great arteries (TGA) before surgery. MATERIALS AND METHODS: Twenty-five patients with TGA who underwent DSCT and transthoracic echocardiography (TTE) examination were retrospectively reviewed. The morphological types of TGA, the spatial relationship between the pulmonary artery and the aorta, as well as coronary artery-associated abnormalities were assessed by DSCT...

The common heart diseases resulting in a brain abscess are associated with a right to left shunt and include tetralogy of Fallot and transposition of great vessels. Atrial septal defect (ASD) is almost always associated with the left to right shunt and therefore is not a commonly considered risk factor for brain abscess. We report the case of a 29-year-old male, with no symptoms of cardiac disease, who presented with the left posterior frontal pyogenic abscess which led to the detection of a silent ASD. Our case emphasizes the need for a careful evaluation of the source of infection in patients with a brain abscess...

Congenitally corrected transposition of great vessels (CCTGV) is a rare congenital heart disease (CHD) accounting for <1% of CHDs. CCTGV with infundibular pulmonary stenosis (PS) with ventricular septal defect (VSD) is part of Fallot's physiology. It is known to be associated with bradyarrhythmias like atrioventricular (AV) blocks, and acquired complete AV block occurs at a rate of 2% per year. Patients can have left-sided accessory pathways, which may cause atrioventricular reentrant tachycardia (AVRT)...

OBJECTIVE: To describe a new sonographic marker of transposition of great arteries (TGA) during the first-trimester screening. METHODS: We reviewed six cases of TGA from 2013 to 2016 in which an antenatal diagnosis of TGA at first-trimester screening (11-13 + 6 weeks of gestation) was confirmed postnatally. We specifically assessed images obtained by scanning the fetal heart in three vessels (3V) and three-vessel with trachea (3VT) views using color Doppler...

In 1799, Matthew Baillie, William Hunter's nephew, published his famous atlas of pathology. It was entitled A Series of Engravings Accompanied with Explanations which are Intended to Illustrate the Morbid Anatomy of Some of the Most Important Parts of the Human Body. The present study aims to match the illustrations to extant specimens in the collections of William and John Hunter, preserved at the University of Glasgow and at the Royal College of Surgeons of England respectively. Baillie's book contains 10 fasciculi, consisting of 73 plates and 206 figures...

Originating as a single vessel emerging from the embryonic heart, the truncus arteriosus must septate and remodel into the aorta and pulmonary artery to support postnatal life. Defective remodeling or septation leads to abnormalities collectively known as conotruncal defects, which are associated with significant mortality and morbidity. Multiple populations of cells must interact to coordinate outflow tract remodeling, and the cardiac neural crest has emerged as particularly important during this process. Abnormalities in the cardiac neural crest have been implicated in the pathogenesis of multiple conotruncal defects, including persistent truncus arteriosus, double outlet right ventricle and tetralogy of Fallot...

Transposition of great arteries (TGA) is more commonly associated with D-malposition of great arteries where anterior aorta produces characteristic "I" sign in the three-vessel view (3VV) in fetal heart imaging. We describe two cases with TGA and L-malposition of aorta where 3VV imaging showed an apparently normal arrangement of vessels while outflow tract imaging proved vital in diagnosing transposition anatomy. Apparently, normal 3VV in the presence of disproportionate vessel caliber and inability to produce normal outflow images should raise the suspicion...

A 29-year-old woman was referred to our hospital due to exacerbation in dyspnea on exertion and easy fatigability. A known case of congenitally corrected transposition of the great vessels and congenital complete heart block, she had already received a permanent single-chamber pacemaker. Decision was made to implant a biventricular pacemaker for the treatment of the failing heart. Excellent coronary sinus lead implantation was done, conferring amelioration of symptoms, QRS narrowing in the electrocardiogram, and improvement of systemic ventricular systolic function in echocardiography...

Situs inversus with levocardia and congenitally corrected transposition of the great arteries represents a relatively very rare congenital condition and most patients are diagnosed in infancy or early age. This case report describes a 35-year old man with congenitally corrected transposition of the great arteries which presented with a five month history of exertional dyspnea. A diagnosis was confirmed by transesophageal echocardiogram, showing situs inversus, levocardia, atrioventricular and ventriculoarterial discordance...

OBJECTIVE: Very few studies have been conducted in this part of world to identify relation between maternal serum homocysteine levels and congenital heart disease in their offsprings. With this perspective in mind, this study was carried out. METHODS: Fifty women were enrolled in this study. Thirty of these had delivered neonates who were diagnosed to have congenital heart diseases. These were treated as cases. Twenty of these women had delivered neonates who did not have any congenital heart diseases and were treated as controls...

BACKGROUND: The presence of a structural cardiac defect in the setting of dextrocardia is extremely rare. Graspable models allow enhanced appreciation of aberrant structures and vascular relations, particularly in rare and complex cases. This is the first case report of the use of a replica of a patients' anatomy to plan the surgical strategy in the setting of dextrocardia. AIMS: We intend to demonstrate the benefit of three-dimensional printing to enhance preoperative planning in complex congenital heart disease undergoing heart transplantation...

Importance: Mortality in patients with congenital heart disease (CHD) has markedly decreased during recent decades because of advancement in pediatric care. However, there are limited data on survival trends in children and young adults with CHD compared with the general population. Objective: To determine survivorship in children and young adults with CHD compared with matched controls. Design, Setting, and Participants: A registry-based, prospective, matched-cohort study was conducted in Sweden...

Incorrect pacemaker lead placement into the systemic ventricle is a complication that has rarely been described in patients with D-transposition status after atrial baffle palliation. We present a case of ventricular lead misplacement in the systemic right ventricle of a patient with D-transposition of the great arteries after Mustard procedure. This case demonstrates the challenges with proper imaging of lead placement in patients with atrial baffles and long-term management of a lead in the systemic ventricle...

OBJECTIVE: To describe the clinical course of paediatric patients undergoing surgery for congenital heart disease in UMAE of Yucatan. METHODS: Descriptive review was performed on the records of paediatric patients undergoing surgery for congenital heart disease from 1 November 2011 to 30 November 2013. RESULTS: The most frequent heart diseases were persistent ductus arteriosus (37.6%) and transposition of the great vessels. The median intensive care stay was 3 days...

Background: Delayed or missed diagnosis of critical and cyanotic congenital heart disease (CHD) in asymptomatic newborns may result in significant morbidity and mortality. The aim of this study was to determine the accuracy of pulse oximetry screening performed on the first day of life for the early detection of critical and cyanotic CHD in apparently normal newborns. Methods: This cross-sectional study used postductal pulse oximetry to evaluate term neonates born between 2008 and 2011 with normal physical examinations...

BACKGROUND: Peak velocity measurements are used to evaluate the significance of stenosis in patients with transposition of the great arteries after the arterial switch operation (TGA after ASO). 4D flow cardiovascular magnetic resonance (CMR) provides 3-directional velocity encoding and full volumetric coverage of the great arteries and may thus improve the hemodynamic evaluation in these patients. The aim of this study was to compare peak velocities measured by 4D flow CMR with 2D phase contrast (PC) CMR and the gold standard Doppler echocardiography (echo) in patients with TGA after ASO...
