BACKGROUND Newer technologies such as three-dimensional mapping and echocardiography can decrease x-ray exposure during catheter ablation. Many right-sided tachycardias can now be ablated without fluoroscopy. Left-sided tachycardias, however, have not yet been ablated using a zero fluoroscopy approach. OBJECTIVE This study sought to examine the utility of(More)
OBJECTIVE To compare the acute success and recurrence rate of cryoablation for left-sided accessory pathways (AP) with controls who underwent radiofrequency ablation (RFA) at the same institution. BACKGROUND Catheter cryoablation of supraventricular tachycardia (SVT) is considered to be a safer alternative a compared with RFA. At our institution,(More)
OBJECTIVE The purpose of this series is to describe the prenatal echocardiographic findings of vascular rings. METHODS The 3-vessel and trachea view consists of the axial view of the upper mediastinum. The normal left aortic arch appears as a V-shaped confluence of the ductus arteriosus and aortic arch, with the trachea situated posterior and to the(More)
We describe a rare case of right atrial isomerism, levocardia, right-side stomach, obstructed supracardiac total anomalous pulmonary venous connection, double outlet right ventricle with complete atrioventricular septal defect and absent spleen. From the pulmonary venous confluence behind the atrium an ascending as well as a descending vertical vein(More)
OBJECTIVE The purpose of this series was to describe the fetal echocardiographic findings in hypoplastic left heart syndrome with aortic atresia and ventriculocoronary arterial communication and implications of these findings. METHODS We describe 2 fetuses with hypoplastic left heart syndrome with ventriculocoronary arterial communication diagnosed at 29(More)
