Left bundle pacing in transposition of the great arteries with previous atrial redirection operation
Matthew O’Connor, S Y Ho, Karen McCarthy, Michael Α. Gatzoulis, Tom Wong
Abstract
Transposition of the great arteries (TGA) is a congenital heart defect characterized by concordant atrioventricular (AV) and discordant ventriculoarterial connections leading to 2 parallel circulatory systems. There are a number of operations that have been performed over the years to surgically palliate this parallel circulation; currently the arterial switch operation is the standard of care. There are occasions where the arterial switch operation is not feasible (for example, owing to hostile coronary anatomy) and alternative surgical approaches such as the more historical Mustard/Senning operations must be used.
