Cross sectional echocardiographic assessment of the extent of the atrial septum relative to the atrioventricular junction in atrioventricular septal defect.
OBJECTIVE To study patients with atrioventricular septal defect to determine the pathognomonic morphological features of the lesion and the relation between the septal structures and the atrioventricular junction. Setting : Tertiary level paediatric cardiology centre. METHODS Cross sectional echocardiograms from 60 patients were reviewed using qualitative and quantitative analysis. The unifyi...
متن کاملAtrioventricular Septal Defect with Common Atrioventricular Junction Guarded by a Common Valve Consisting of Left Atrioventricular Trifoliate Valve
INTRODUCTION Atrioventricular septal defect with common atrioventricular junction is a rare adult congenital cardiac syndrome. This occurrence with prolonged survival is exceptionally rare. CASE REPORT We present the case of a patient who presented with this defect with common atrioventricular junction who survived to the age of 32. We describe a 32-year-old man with atrioventricular septal d...
متن کاملCatheter modification of the atrioventricular junction with radiofrequency energy for control of atrioventricular nodal reentry tachycardia.
BACKGROUND The utility of transcatheter application of radiofrequency energy to eliminate atrioventricular nodal reentrant tachycardia (AVNRT) was investigated. METHODS AND RESULTS Thirty-nine patients (mean age, 53 +/- 20 years; range 14-86 years) with medically refractory AVNRT underwent perinodal ablation with radiofrequency energy. A custom-designed 6F catheter with a large (3-mm-long) di...
متن کاملOptical mapping of the atrioventricular junction.
In the normal heart, the atrioventricular node (AVN) is part of the sole pathway between the atria and ventricles, and is responsible for the appropriate atrial-ventricular delay. Under normal physiological conditions, the AVN controls appropriate frequency-dependent delay of contractions. The AVN also plays an important role in pathology: it protects ventricles during atrial tachyarrhythmia, a...
متن کاملOptical Mapping of the Human Atrioventricular Junction
Fluorescent optical mapping of cardiac electrophysiology in animal models has produced a wealth of information about the function of the cardiac pacemaking and conduction system. However, expanding optical mapping studies to the human conduction system will significantly increase our understanding of clinically relevant phenomena, such as atrioventricular nodal reentrant tachycardia, that are d...
