Why the study?
Does pacemaker implantation improve left ventricular end-diastolic diameter, shortening fraction, and cardiothoracic ratio in patients with isolated congenital complete atrioventricular block?
Population
149 patients with isolated congenital complete atrioventricular block (CCAVB)
Comparison
Pacemaker (PM) implantation vs Non-pacemaker state

May support earlier pacing in asymptomatic patients with cardiomegaly; leaves open need for randomized confirmation in congenital AV block.
Does pacemaker implantation improve left ventricular end-diastolic diameter, shortening fraction, and cardiothoracic ratio in patients with isolated congenital complete atrioventricular block?
Pacemaker implantation in patients with isolated congenital complete atrioventricular block is associated with a significant decrease in heart size and normalization of shortening fraction, suggesting asymptomatic patients with increased cardiac size may benefit from earlier intervention.
