Resynchronization of Left Ventricular Contraction After Reimplantation of Anomalous Left Coronary Artery

Spontaneous resynchronization of dyskinetic segments of the left ventricle occurs after coronary bypass surgery in adults and has been shown in some children. It is, however, unknown what degree of dyskinesis is likely to be reversible in infants with ischemia from anomalous coronary arteries and what criteria would indicate that a resynchronization strategy of biventricular pacing might be needed. These questions need data from quantitative serial tissue Doppler observations of patients from pre-operative to late post-operative follow-up.
