In a series of over 6000 patients referred for fetal echocardiography during an eight year period, 37 fetuses were found to have complete heart block. There were 16 cases of isolated heart block and 21 cases associated with structural heart disease. All mothers of fetuses with isolated complete heart block had evidence of circulating syndrome Sjögren A antibody (Ro). Only one mother had clinica...

BACKGROUND The risk of complete heart block (CHB) from congenital heart repairs in Ghana is unknown. This information is important for referring physicians and in pre-operative counselling of patients and facilitates the process of obtaining informed consent for such repairs. OBJECTIVES This study was undertaken to determine the incidence of permanent post-operative CHB requiring pacemaker im...

BACKGROUND The ventricular septal defect (VSD) is the most common form of congenital heart defects. The purpose of this study was to evaluate the results of the early complications and mid-term follow-up of the transcatheter closure of the VSD using the Amplatzer VSD Occluder. METHODS Between April 2012 and October 2013, 110 patients underwent the percutaneous closure of the perimembranous VS...

A genetic predisposition associated with HLA B27 for developing complete heart block with or without clinical or radiological signs of associated rheumatic disease has recently been found. In this electrophysiological study of 12 patients with spontaneous complete heart block and HLA B27 associated disease, of whom eight had ankylosing spondylitis, 10 had suprahisian second or third degree atri...

Background. Congenital heart block is characterized by blockage of electrical impulses from the atrioventricular node (AV node) to the ventricles. This blockage can be caused by ion channel impairment that is the result of genetic variation. This study aimed to investigate the possible causative variants in a Thai family with complete heart block by using whole exome sequencing. Methods. Genomi...
